(2) | When the integer part of result exceeds 10 digits, the display will show 10 most significant digits of result divided by 10*'° and “E”. (3) | When the integer part of result exceeds 19 digits, display will show a zero and “E”. (4) | When the integer part of result in memory register exceeds 10 digits at memory calculation, display will show a zero and “E”, and previous data will be kept in memory resister. (5) When an overflow occurs on the way of add-on/discount calculation, display will show a zero and “E”. (6) | When square root of any negative number is attempted, “E” and square root of absolute value are displayed. (7) In overflow condition, any operation or numeral entry will be inhibited. Clearing Overflow Condition (1) The resulting overflow condition can be cleared by depressing [ON/C/CE] - (2) | At memory overflow condition, depression of [mB] after ION/C/CE] will recall the previous memory data.

The first of a sequence of data keys will clear the contents of display register before being entered. The decimal point key will be accepted the first time it is depressed during calculations. (2) Arithmetic Operation Keys The arithmetic operation keys include the plus [+], minus [=] , multiply [x], divide [=], equal[=], percent [%], square root , memory add , memory subtract [M-], sign change [+7 —], data shift 5]. Depression of this key conditions the calculator for addition of display register to upper register. If the calculator was previously conditioned for add, subtract, multiply or device, those operation would be performed with the resultant intermediate sum, difference, product or quotient displayed and previous modes and reset, and calculator stores add command. In the successive depressions of this key, the first will perform the previously enabled mode and more than twice depressions will be ignored. | Depression of this key performs the same function as the[+] key with the exception that calculator stores subtract mode. Depression of this key conditions the calculator for multiplication of upper register and display register. If the calculator was previously conditioned for add, subtract multiply or divide, those operation would be performed with the resultant intermediate sum, difference, product or quotient displayed. And then set the multiply mode. 1998-12-02 8/34

TOSHIBA T9947S,JT9947X-AS [M=] Depression of this key will perform the same function as the[M-+] with the exception that the calculator result or displayed number is subtracted from the memory register. E] Depression of this key following numeral entry will perform the previously enabled mode. lf no number has been entered, the displayed number will be used to perform the previously enabled mode. If no mode are enabled, this key will be ignored. If multiplication or division are enabled, constant mode operations are performed by termination a sequence of operations with the E] key, entering a new number and depressing the [=] key. Any key sequence terminated with, [=] key will not require the use of ION/C/CE] key before a new operation sequence can be initiated. If the calculator was previously conditioned for addition, or subtraction or multiplication or divination, calculations would be performed as follows. a+b[%] a+arb/100 a-b[%] a-a-b/100 axb[%] a-b/100 azb 100 a/b If no mode are enabled, this key will be ignored. If multiplication or division are enabled, constant mode operations are performed by terminating a sequence of operation with the Pe] key, entering new number and depressing the [%] key. Depression of this key will perform the previously enabled mode and add the result to memory register and leave the result in the display register. If no modes are enabled, the displayed number is added to memory register by this key. Any key sequence terminated with[M+] will not require the use of the [ON:/C/CE] key before a new operation sequence can be initiated. “TAB” fixed point mode selectable E] Depression of this key performs a similar function as the [x] key except that division of upper register by display register is either set up or performed and the divide mode is activated. 1998-12-02 9/34

TOSHIBA T9947S,JT9947X-AS Depression of this key calculated the square root of number displayed without changing modes of operation. Depression of this key following [+], [=], [x], or [=] keys will transfer the contents of display register to upper register and calculate the square root of number displayed. The entry of a new number following this key clear the previous display. Depression of this key will change the sign of display register. Depression of this key will shift the right data of display register. (3) | Command Function Keys The command function keys include the clear entry/clear all [ON/C/CE] , recall /clear memory Depression of this key following GE], (I). [x] or [] will transfer the contents of display register to upper register and recall the contents of memory register to display register. key following [=] , [%], [M+], [M=]or any number key will recall the contents of memory register to the display register without affecting any other operations in progress. Successive depressions of key will clear the memory register. ION/C/CE] Depression of this key after Im]. +]. or numeral keys will clear the display register. You can reset the error symbol “E” if you depress [ON/C/CE] at the condition of exceeding capacity error. Depression of this key will off the LSI. Arithmetic Operations 1. Addition Key Op.

Storage criteria Solid state chips, unlike packaged devices, are non-hermetic devices normally fragile and small in physical size, and therefore, require special handling considerations as follows :

9.1 Chips must be stored under proper conditions to insure that they are not subjected to a

moist and/or contaminated atmosphere that alter their electrical, physical, or mechanical characteristics. After the shipping container is opened, the chips must be stored under the following conditions : A. Storage temperature, 40°C max. B. Relative humidity, 50% max. C. Clean, dust-free environment.

9.2 The user must exercise proper care when handling chips or wafers to prevent even the

slightest physical damage to the chip.

9.3 During mounting and lead bounding of chips the user must use proper assembly techniques

to obtain proper electrical, thermal, and mechanical performance.

9.4 After the chip has been mounted and bounded, any necessary procedure must be followed

by the user to insure that these non-hermetic chips are not subjected to moist or contaminated atmosphere which might cause the development of electrical conductive paths across the relatively small insulating surfaces. In addition, proper consideration must be given to the protection of these devices from other harmful environments which could conceivably adversely affect their proper performance. 1998-12-02 29/34

TOSHIBA T9947S,JT9947X-AS 10.Handling criteria The user should find the following suggested precautions helpful in handling chips. In any event, because of the extremely small size and fragile nature of chips, care should be taken in handling these devices.

10.1 Grounding

a) Bonders, pellet pickup tools, table tops, trim and form tools, sealing equipment, and other equipment used in chip handling should be properly grounded. b) Operator should be properly grounded.

10.2 In-process handling

a) Assemblies or subassemblies of chips should be transported and stored in conductive carriers. b) All external leads of the assemblies or subassemblies should be shorted together. VISUAL INSPECTION CRITERIA 1. Visual inspection magnification shall be 40 x in principle. 2. Defects defined :

2.1 Thickness

See the technical data sheet.

2.2 Chip and crack

A die shall be rejected if : a) Any crack of chip extends greater than 35m in length into the inside of the scribble line. (see Fig.1) 2.3. Metallization A die shall be rejected if : a) More than 25% of the designed area of the metallization is missing at any bonding pad. b) There is a short or break which affects electrical characteristics in any lead pattern. (see Fig.2)

2.4 Glass protection coat

A die shall be rejected if : a) It exhibits glass protection coat which covers more than 25% of any active bonding pad. 9998-12-02 30/34

2.5 Attached foreign material

A die shall be rejected if : a) A die is covered by stains or attached foreign material which size is more than 5 times as large as a bonding pad area. b) It exhibits residual ink, stains or attached foreign material which covers more than 20% of any active bonding pad. (see Fig.3)

2.6 Others

A die shall be rejected if : a) There have no evident probed impression on the bonding pads. b) A inked die, defective die, is intermized. 3. Limit samples should be fized, if necessary. + Scribe line Short Break _ Die edge a 35pm Fig.1 Fig.2 Lead pattern Stain or foreign materials Ay Fig.3 1998-12-02 31/34
