AT27LV256A

AT27LV256A Features Fast Read Access Time - 70 ns Dual Voltage Range Operation Low Voltage Power Supply Range, 3.0V to 3.6V or Standard 5V ± 10% Supply Range Pin Compatible with JEDEC Standard AT27C256 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 28-Lead 330-mil SOIC 28-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 Integrated Product Identification Code Commercial and Industrial Temperature Ranges 256K (32K x 8) Low Voltage OTP CMOS EPROM Description The AT27LV256A is a high performance, low power, low voltage 262,144 bit one-time programmable read only memory (OTP EPROM) organized as 32K by 8 bits. It requires only one supply in the range of 3.0V to 3.6V in normal read mode operation, making it ideal for fast, portable systems using battery power. Atmel’s innovative design techniques provide fast speeds that rival 5V parts while keeping the low power consumption of a 3.3V supply. At VCC = 3.0V, any byte can be accessed in less than 70 ns. With a typical power dissipation of only 18 mW at 5 MHz and VCC = 3.3V, the AT27LV256A consumes less than one fifth the power of a standard 5V EPROM.
