The AT27C010/L in available in a choice of industry stand- ard JEDEC-approved one-time programmable (OTP) plastic PDIP, PLCC, and TSOP packages. All devices fea- ture two line control ( CE, OE) to give designers the flexibil- ity to prevent bus contention. With 128K byte storage capability, the AT27C010/L allows firmware to be stored reliably and to be accessed by the system without the delays of mass storage media. Atmel’s 27C010/L have additional features to ensure high quality and efficient production use. The Rapid  Program- ming Algorithm reduces the time required to program the part and guarantees reliable programming. Programming time is typically only 100 µs/byte. The Integrated Product Identification Code electronically identifies the device and manufacturer. This feature is used by industry standard programming equipment to select the proper program- ming algorithms and voltages. Description (Continued) Switching between active and standby conditions via the Chip Enable pin may produce transient voltage excur- sions. Unless accommodated by the system design, these transients may exceed data sheet limits, resulting in de- vice non-conformance. At a minimum, a 0.1 µF high fre- quency, low inherent inductance, ceramic capacitor should be utilized for each device. This capacitor should be connected between the V CC and Ground terminals of the device, as close to the device as possible. Additionally, to stabilize the supply voltage level on printed circuit boards with large EPROM arrays, a 4.7 µF bulk electrolytic capacitor should be utilized, again connected between the V CC and Ground terminals. This capacitor should be posi- tioned as close as possible to the point where the power supply is connected to the array. 3-154 AT27C010/L

(1) VPP Supply Voltage with *NOTICE: Stresses beyond those listed under “Absolute Maxi- mum Ratings” may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions beyond those indi- cated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Note: 1. Minimum voltage is -0.6V dc which may undershoot to -2.0V for pulses of less than 20 ns. Maximum out- put pin voltage is V CC + 0.75V dc which may over- shoot to +7.0V for pulses of less than 20 ns.

The ad- dress is set to the first location. VCC is raised to 6.5V and VPP is raised to 13.0V. Each address is first programmed with one 100 µs PGM pulse without verification. Then a verification / reprogramming loop is executed for each ad- dress. In the event a byte fails to pass verification, up to 10 successive 100 µs pulses are applied with a verifica- tion after each pulse. If the byte fails to verify after 10 pulses have been applied, the part is considered failed. After the byte verifies properly, the next address is se- lected until all have been checked. V PP is then lowered to 5.0V and VCC to 5.0V. All bytes are read again and com- pared with the original data to determine if the device passes or fails. AT27C010/L 3-159
