AT27LV040A

Features Fast read access time – 90ns Dual voltage range operation – Low voltage power supply range, 3.0V to 3.6V, or – Standard power supply range, 5V  10% Compatible with JEDEC standard Atmel® AT27C040 Low-power, 3.3V CMOS operation – 20µA max standby (less than 1µA, typical) for VCC = 3.6V – 36mW max active at 5MHz for VCC = 3.6V JEDEC-standard package – 32-lead PLCC High-reliability CMOS technology – 2,000V ESD protection – 200mA latchup immunity Rapid programming algorithm – 100µs/byte (typical) CMOS- and TTL-compatible inputs and outputs – JEDEC standard for LVTTL Integrated product identification code Industrial temperature range Green (Pb/halide-free) packaging option 4Mb (512K x 8) Low Voltage, One-time Programmable, Read-only Memory Atmel AT27LV040A 1. Description The Atmel AT27LV040A is a high-performance, low-power, low-voltage, 4,194,304-bit, one-time programmable, read-only memory (OTP EPROM) organized as 512K by 8 bits. It requires only one supply in the range of 3.0 to 3.6V in normal read mode operation, making it ideal for fast, portable systems using battery power. The Atmel innovative design techniques provide fast speeds that rival 5V parts while keeping the low power consumption of a 3V supply. At VCC = 3.0V, any byte can be accessed in less than 90ns. With a typical power dissipation of only 18mW at 5MHz and VCC = 3.3V, the AT27LV040A consumes less than one-half the power of a standard, 5V EPROM. Standby mode supply current is ty...
