Description

The AT27BV4096 is a high performance, low power, low voltage 4,194,304-bit one-

time programmable read only memory (OTP EPROM) organized as 256K by 16 bits. It

requires only one supply in the range of 2.7V to 3.6V in normal read mode operation.

The by-16 organization makes this part ideal for portable and handheld 16 and 32 bit

microprocessor based systems using either regulated or unregulated battery power.

Atmel’s innovative design techniques provide fast speeds that rival 5V parts while keeping the low power consumption of a 3V supply. At V CC = 2.7V, any word can be accessed in less than 120 ns. With a typical power dissipation of only 18 mW at 5 MHz and VCC = 3V, the AT27BV4096 consumes less than one fifth the power of a standard 5V EPROM. Standby mode supply current is typically less than 1 µA at 3V.

AT27BV4096 Programming Waveforms(1) Notes: 1. The Input Timing Reference is 0.8V for VIL and 2.0V for VIH. 2. tOE and tDFP are characteristics of the device but must be accommodated by the programmer. 3. When programming the AT27BV4096 a 0.1 µF capacitor is required across VPP and ground to suppress spurious voltage transients. DC Programming Characteristics TA = 25 ± 5°C, VCC = 6.5 ± 0.25V, VPP = 13.0 ± 0.

AT27BV4096 Rapid Programming Algorithm A 50 µs CE pulse width is used to program. The address is set to the first location. V CC is raised to 6.5V and V PP is raised to 13.0V. Each address is first programmed with one 50 µs CE pulse without verification. Then a verification / reprogramming loop is executed for each address. In the event a word fails to pass verification, up to 10 successive 50 µs pulses are applied with a verification after each pulse.
