A276308A Functional Description Read Mode Auto Identify Mode The A276308A has two control functions, both of which must be logically active in order to obtain data at the outputs. CE is the power control and should be used for device selection. OE is the output control and should be used to data to the output pins, which is independent of device selection. Assuming that addresses are stable, address access time (tAA) is equal to the delay from CE to output (tCE). Data is available at the output after a delay (tOE) from the falling edge of OE , as long as CE has been low and the addresses have been stable for at least tAA - tOE. The auto identify mode allows the reading out of a binary code from a EPROM that will identify its manufacturer and type. This mode is intended for use by programming equipment for the purpose of automatically matching the device to be programmed with its corresponding programming algorithm. To activate the mode, the programming equipment must apply 12.0V ± 0.5V on address line A9 of the A276308A. Three identification code can be read from data output pin by toggling A0 and A1. The other addresses must be held at VIL during this mode. Byte 0 (with A0 at VIL, A1 at VIL) represents the manufacturer code which is 37H. Byte 1 and Byte 2 represent the device code and continuation code, which is 2CH and 7FH respectively. All identifiers for these codes will possess odd parity, with MSB (IO7) defined the parity bit. Standby Mode The A276308A has a standby mode which reduces the active current from 30mA to 100µA. The A276308A is placed in the standby mode by applying a CMOS high signal to CE . When in the standby mode, the output are in a high impedance state, independent of the OE .

Exposure to the absolute maximum rating conditions for extended periods may affect device reliability. Notes: 1. During voltage transitions, the input may undershoot GND to -2.0V for periods less than 20 ns. Maximum DC voltage on input and I/O may overshoot to VCC + 2.0V for periods less than 20 ns. 2. When transitions, A9 and VPP may undershoot GND to -2.0V for periods less than 20 ns. Maximum DC input voltage on A9 and VPP is +13.5V which may overshoot to 14.0V for period less than 20 ns.

A276308A an additional pulse programming is applied for a maximum of 25 pulses. On completion of 1 byte programming and, The verified address is incremented. After the final address is completed, all bytes are verified again with VCC = 5.0 Volt. Programming and Program Verify The programming flowchart is shown in Page 10. The A276308A is shipped with all bits being set to "1". Programming causes relevant bits to be changed to "0". The programming mode is started by setting VCC to 6.25V, OE /VPP to +12.75V and CE is at VIL. Data to be programmed can be directly input in the 8 bit format through the data bus. Program Inhibit This mode is used to program one of multiple A276308A whose VCC, address bus and data bus are connected in parallel. When programming is performed, other A276308A can be inhibited from being programmed by setting their CE pins to VIH and OE /VPP pins to +12.75V. The write programming algorithm reduces programming time by using 100µs pulse followed by a byte verification to determine whether the byte has been successfully programmed.
