AT27C256R-70PC [Microchip]

The AT27C256R is a low-power, high-performance 262,144-bit 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. 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 mA in Standby. Features include 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, Industrial and Automotive Temperature Ranges.
