AT28C64-20JC Description

Short technical summary and product information.

The Microchip Technology AT28C64-20JC is a 64Kbit non-volatile electrically erasable and programmable read-only memory (EEPROM) with a parallel interface. It is organized as 8K words by 8 bits, providing 64Kbit of storage capacity.

 

Key electrical specifications include a typical access time of 120 ns (from datasheet) or 150 ns (from manufacturer page), and a fast byte write cycle time of 200 µs or 1 ms. The device operates from a supply voltage of 4.5V to 5.5V and features low power consumption with a typical active current of 30 mA and a CMOS standby current of 100 µA.

 

Designed for reliability, the AT28C64 offers high endurance and data retention. It operates within a temperature range of 0°C to 70°C (TC) for commercial applications, though datasheet indicates industrial ranges are also available. The component is housed in a 32-PLCC (J-Lead) surface-mount package, measuring 13.97mm x 11.43mm.

 

This EEPROM is suitable for applications requiring persistent data storage, such as firmware storage, embedded systems, and legacy computing equipment. Its parallel interface allows for direct microprocessor control, simplifying integration.
