Microchip Technology's 28C64B-70I-K is a 64-kilobit (8K x 8) CMOS Electrically Erasable Programmable Read-Only Memory (EEPROM). This parallel interface device operates with a maximum access time of 70ns and supports asynchronous operation. Key features include data polling for status monitoring and automatic write capability. The device is housed in a 32-terminal Ceramic Quad Flat Pack (CQFP) package, designated by the JESD-30 code R-CQCC-N32, with a terminal pitch of 1.27mm. It operates over an industrial temperature range of -40°C to +85°C with a supply voltage range of 4.5V to 5.5V. The 28C64B-70I-K is suitable for applications in industrial control systems, data logging, and embedded computing where reliable non-volatile data storage is critical.
