The Microchip Technology AT27C040-90PU is a high-performance, low-power 4,194,304-bit One-Time Programmable (OTP) Read-Only Memory (ROM) organized as 512K by 8 bits. It features a fast read access time of 90 ns, suitable for high-performance microprocessor systems. The device operates from a single 5V ±10% power supply and consumes low power, with typical active current of 8mA and standby current less than 10μA.
This EPROM memory utilizes Atmel's scaled CMOS technology, ensuring both low active power consumption and fast programming capabilities. It supports a rapid programming algorithm, typically 100μs/byte, for efficient production use. The AT27C040-90PU is available in industry-standard JEDEC-approved packages, including the 32-lead PDIP and 32-lead PLCC. Its inputs and outputs are CMOS- and TTL-compatible, and it operates within an industrial temperature range of -40°C to 85°C.
Designed for reliability, the AT27C040-90PU includes 2000V ESD protection and 200mA latchup immunity. The device features two-line control (CE, OE) to prevent bus contention in high-speed systems. It is supplied in a 32-DIP (0.600", 15.24mm) through-hole package, making it suitable for various electronic designs requiring non-volatile memory storage.
