The Microchip Technology AT28HC64B-70SU-235 is a 64K bit (8K x 8) parallel EEPROM utilizing advanced CMOS technology. This device offers a fast 70ns access time, enabling efficient data retrieval. Its asynchronous operating mode and parallel interface simplify integration into various system architectures. The AT28HC64B features data polling and a toggle bit for write-in-progress detection, alongside a minimum data retention of 10 years and an endurance rating of 100,000 write cycles. Operating within a supply voltage range of 4.5V to 5.5V, it consumes a typical supply current of 40mA and a low standby current of 100µA. This component is housed in a 28-lead PDSO (SOP) package with a 1.27mm terminal pitch, suitable for surface mounting. Applications span industrial control, automotive systems, and data logging where non-volatile storage is critical.
