1 / 9 page AT27C256R Description The AT27C256R is a low-power, high performance 262,144 bit one-time programma- ble 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. Atmel’s scaled CMOS technology provides low active power consumption, and fast programming. Power consumption is typically only 8 mA in Active Mode and less than 10 µA in Standby. (continued) 256K (32K x 8) OTP CMOS EPROM 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 Pin Configurations Pin Name Function A0 - A14 Addresses O0 - O7 Outputs CE Chip Enable OE Output Enable NC No Connect PDIP, SOIC Top View Note: PLCC Package Pins 1 and 17 are DON’T CONNECT.
