The Microchip Technology AT27C512R-45PU is a 512Kbit, one-time programmable (OTP) EPROM, organized as 64K x 8 bits. This memory device offers a fast read access time of 45ns, suitable for high-performance microprocessor systems without the need for wait states.
It operates with a single 5V power supply (±10%) and features low-power CMOS operation, consuming a typical 8mA in active mode and less than 10µA in standby. The device is designed for high reliability with 2,000V ESD protection and 200mA latchup immunity. Inputs and outputs are compatible with both CMOS and TTL logic levels.
The AT27C512R-45PU is available in a standard 28-lead PDIP package, designed for through-hole mounting. It also supports industrial and automotive temperature ranges (-40°C to 85°C TC). The device includes an integrated product identification code for programming equipment.
This EPROM memory is ideal for firmware storage where reliable access without mass storage delays is required. It also offers a green (Pb/halide-free) packaging option.
