Description

The AT27BV512 is a high performance, low power, low voltage 524,288-bit one-time

programmable read only memory (OTP EPROM) organized as 64K by 8 bits. It

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

making it ideal for fast, portable 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 C C = 2.7V, any byte can be accessed in less than 70 ns. With a typical power consumption of only 18 mW at 5 MHz and V CC = 3V, the AT27BV512 consumes less than one fifth the power of a standard 5V EPROM. Standby mode supply current is typically less than 1 µA at 3V.

AT27BV512 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 AT27BV512, 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, OE/VPP = 13.0 ± 0.

AT27BV512 Rapid Programming Algorithm A 100 µs CE pulse width is used to program. The address is set to the first location. VCC is raised to 6.5V and OE/VPP is raised to 13.0V. Each address is first programmed with one 100 µs CE pulse without verification. Then a verification / reprogramming loop is executed for each address. In the event a byte fails to pass verification, up to 10 successive 100 µs pulses are applied with a verification after each pulse.
