The Microchip Technology 28C64B-12I-D is a 65536-bit electrically erasable programmable read-only memory (EEPROM) organized as 8K words by 8 bits. This parallel interface device features a maximum access time of 120ns and operates with a 5V supply voltage (4.5V to 5.5V) using advanced CMOS technology. The 28C64B series supports asynchronous operation and includes features such as data polling for write completion confirmation and automatic write operations. Its 28-pin ceramic dual in-line package (CDIP28) with through-hole termination is suitable for applications requiring robust environmental resistance. This component is commonly found in industrial control systems, automotive electronics, and data logging applications where reliable non-volatile storage is critical. Standby current is a maximum of 150µA, with an active supply current of 70mA. The write cycle time is rated at a maximum of 1ms.
