AT27C256R-45PU - Microchip

Description: The Atmel® AT27C256R is a low-power, high-performance, 262,144-bit, one-time programmable, read-only memory (OTP EPROM) organized as 32K by 8 bits. It requires only one 5V power supply in normal read mode operation. Any byte can be accessed in less than 45ns, eliminating the need for speed reducing WAIT states on high-performance microprocessor systems. The Atmel scaled CMOS technology provides low active power consumption and fast programming. Power consumption is typically only 8mA in active mode and l
