  • Overview
    AT27C256R-15PC Product overview

    Description The AT27C256R is a low-power, high performance 262,144 bit one-time programmable read only memory (OTP EPROM) organized 32K by 8 bits. It requires only one 5V power supply in normal read mode operation. Any byte can be accessed in less than 45 ns, eliminating the need for speed reducing WAIT states on high performance microprocessor systems. Features •Fast Read Access Time - 45 ns •Low Power CMOS Operation   100 µA max. Standby   20 mA max. Active at 5 MHz •JEDEC Standard Packages   28-Lead 600-mil PDIP   32-Lead PLCC   28-Lead TSOP and SOIC •5V± 10% Supply •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 •Integrated Product Identification Code •Commercial and Industrial Temperature Ranges
