Microchip Technology's 28C64B-90I-D is an 8K x 8 (64 kilobit) CMOS EEPROM featuring parallel interface and a maximum access time of 90ns. This component operates asynchronously and supports data polling and ready/busy status for efficient write operations. The 28C64B-90I-D is housed in a 28-lead ceramic dual in-line package (CDIP28) with through-hole mounting. Its operating temperature range is -40°C to +85°C, with a supply voltage range of 4.5V to 5.5V. This device is suitable for applications in industrial control, automotive systems, and telecommunications infrastructure. The EEPROM offers a 3-state output characteristic and a write cycle time of up to 1ms.
