4 FN8127.2 September 16, 2005 Pin Description Principles of Operation Power-on Reset Application of power to the X5083 activates a power-on reset circuit. This circuit goes LOW at 1V and pulls the RESET pin active. This signal prevents the system microprocessor from starting to operate with insufficient voltage or prior to stabilization of the oscillator. RESET active also blocks communication to the device through the SPI interface. When VCC exceeds the device VTRIP value for 200ms (nominal) the circuit releases RESET, allowing the processor to begin executing code. While VCC < VTRIP communications to the device are inhibited. Low Voltage Monitoring During operation, the X5083 monitors the VCC level and asserts RESET if supply voltage falls below a preset minimum VTRIP. The RESET signal prevents the microprocessor from operating in a power fail or brownout condition and terminates any SPI communication in progress. The RESET signal remains active until the voltage drops below 1V. It also remains active until VCC returns and exceeds VTRIP for 200ms. When VCC falls below VTRIP, any communications in progress are terminated and communications are inhibited until V CC exceeds VTRIP for tPURST. Watchdog Timer The watchdog timer circuit monitors the microprocessor activity by monitoring the WDI input. The microprocessor must toggle the CS /WDI pin periodically to prevent a RESET signal. The CS/WDI pin must be toggled from HIGH to LOW prior to the expiration of the watchdog time out period. The state of two nonvolatile control bits in the status register determine the watchdog timer period. The microprocessor can change these watchdog bits with no action taken by the microprocessor these bits remain unchanged, even after total power failure. VCC Threshold Reset Procedure The X5083 is shipped with a standard VCC threshold (VTRIP) voltage. This value will not change over normal operating and storage conditions. However, in applications where the standard V TRIP is not exactly right, or if higher precision is needed in the VTRIP value, the X5083 threshold may be adjusted. The procedure is described below, and uses the application of a high voltage control signal. Setting the VTRIP Voltage This procedure is used to set the VTRIP to a higher voltage value. For example, if the current VTRIP is 4.4V and the new VTRIP is 4.6V, this procedure will directly make the change. If the new setting is to be lower than the current setting, then it is necessary to reset the trip point before setting the new value. PIN (SOIC/ PDIP) PIN TSSOP NAME FUNCTION 13 C S /WDI Chip Select Input. CS HIGH, deselects the device and the SO output pin is at a high impedance state. Unless a nonvolatile write cycle is und erway, the device will be in the standby power mode. CS LOW enables the device, placing it in the active power mode. Prior to the start of any operation after power-up, a HIGH to LOW transition on CS is required. Watchdog Input. A HIGH to LOW transition on the WDI pin restarts the Watchdog timer. The absence of a HIGH to LOW transition within the watchdog time out period results in RESET going active. 24 S O Serial Output. SO is a push/pull serial data output pin. A read cycle shifts data out on this pin. The falling edge of the serial clock (SCK) clocks the data out. 57 S I Serial Input. SI is a serial data input pin. Input all opcodes, byte addresses, and memory data on this pin. The rising edge of the serial clock (SCK) latches the input data. Send all opcodes (Table 1), addresses and data MSB first. 68 S C K Serial Clock. The Serial Clock controls the serial bus timing for data input and output. The rising edge of SCK latches in the opcode, address, or data bits present on the SI pin. The falling edge of SCK changes the data output on the SO pin. 35 W P Write Protect. When WP is LOW, nonvolatile write operations to the memory are prohibited. This “Locks” the memory to protect it against inadvertent changes when WP is HIGH, the device operates normally.

7 1 RESET Reset Output. RESET is an active LOW, open drain output which goes active whenever VCC falls below the minimum VCC sense level. It will remain active until VCC rises above the minimum VCC sense level for 250ms. RESET goes active if the watchdog timer is enabled and CS remains either HIGH or LOW longer than the selectable watchdog time out period. A falling edge of CS will reset the watchdog timer. RESET goes active on power-up at about 1V and remains active for 250ms after the power supply stabilizes. X5083
