Microchip Technology's 28C64B-90B-UC is a 64 Kbit CMOS EEPROM featuring an 8K x 8 memory organization. This parallel interface device offers a fast 90ns access time and operates over a wide temperature range of -55°C to +125°C. The 28C64 series component supports data polling and has a ready/busy output for status indication. It is housed in a 32-terminal ceramic chip carrier (CQCC32) package, identified by JESD-30 code R-XQCC-N32. This component is suitable for applications in the industrial, automotive, and aerospace sectors requiring non-volatile data storage. The device is designed for surface mounting and utilizes a 5V nominal supply voltage with a standby current of 250µA and a maximum supply current of 80mA. The write cycle time is a maximum of 1ms.
