Microchip Technology presents the 28C64AT-25-SO, an 8K x 8 CMOS EEPROM operating from a 4.5V to 5.5V supply. This device offers a maximum access time of 250ns and supports asynchronous operation with parallel interface. Key features include automatic write, bulk erase capability, and data retention exceeding 10 years. The 28C64 Series component is housed in a 28-lead Small Outline Package (PDSO28, R-PDSO-G28) with a 1.27mm terminal pitch, suitable for surface mounting. Applications for this memory component span industrial automation, consumer electronics, and telecommunications systems. Standby current is rated at 100µA max, with a maximum operating current of 30mA. The write cycle time is 1ms max.
