The AT28HC256-12PI from Microchip Technology is a high-performance, 256Kbit electrically erasable and programmable read-only memory (EEPROM). Organized as 32,768 words by 8 bits, this non-volatile memory device utilizes advanced CMOS technology for fast operation and low power consumption.
Key electrical specifications include a fast read access time of 70 ns, a supply voltage range of 4.5V to 5.5V, and a typical page write cycle time of 10ms. It features automatic page write operation with internal latches for up to 64 bytes, and DATA Polling for end-of-write detection. The device operates efficiently with an active current of 80 mA and a standby current of less than 5 mA.
Designed for reliability, the AT28HC256 offers endurance of 10^4 to 10^5 cycles and data retention of 10 years. It is housed in a 28-PDIP through-hole package, suitable for industrial control systems and consumer electronics where dependable data storage is essential. The operating temperature range is -40°C to 85°C (TC).
This EEPROM supports hardware and software data protection features. Its JEDEC approved byte-wide pinout and compatibility with CMOS and TTL inputs/outputs make integration straightforward. The device also offers a green (Pb/Halide-free) packaging option.
