The Microchip Technology AT27C256R-45PU is a 262,144-bit, one-time programmable (OTP) read-only memory organized as 32K by 8 bits. This EPROM offers a fast read access time of 45ns, eliminating the need for speed-reducing WAIT states in high-performance microprocessor systems.
Designed for low-power CMOS operation, it consumes minimal power in both active and standby modes. The device operates from a single 5V power supply (±10%) and features CMOS- and TTL-compatible inputs and outputs. It includes high-reliability features such as 2,000V ESD protection and 200mA latchup immunity.
The AT27C256R-45PU is available in a JEDEC standard 28-lead PDIP package, suitable for through-hole mounting. It operates across an industrial temperature range of -40°C to 85°C.
Key features include a rapid programming algorithm for efficient programming and an integrated product identification code for automatic device recognition by programming equipment.
