AT27BV040

AT27BV040 Features Fast Read Access Time - 120 ns Dual Voltage Range Operation Unregulated Battery Power Supply Range, 2.7V to 3.6V or Standard 5V ± 10% Supply Range Compatible with JEDEC Standard AT27C040 Low Power CMOS Operation 20 µA max. (less than 1 µA typical) Standby for VCC = 3.6V 29 mW max. Active at 5 MHz for VCC = 3.6V JEDEC Standard Packages 32-Lead PLCC 32-Lead TSOP High Reliability CMOS Technology 2,000V ESD Protection 200 mA Latchup Immunity Rapid™ Programming Algorithm - 100 µs/byte (typical) CMOS and TTL Compatible Inputs and Outputs JEDEC Standard for LVTTL and LVBO Integrated Product Identification Code Commercial and Industrial Temperature Ranges Description The AT27BV040 chip is a high performance, low power, low voltage, 4,194,304 bit one-time programmable read only memory (EPROM) organized as 512K by 8 bits. It requires only one supply in the range of 2.7 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 VCC = 2.7V, any byte can be accessed in less than 100 ns. With a typical power dissipation of only 18 mW at 5 MHz and VCC = 3V, the AT27BV040 consumes less than one fifth the power of a standard 5V EPROM. Standby mode supply current is typically less than 1 µA at 3V. The AT27BV040 simplifies system design and stre...
