Microchip Technology's 27HC641L-70I-J is an 8K x 8 UV Erasable Programmable Read-Only Memory (UVPROM) with a 70ns access time. This CMOS device offers a memory density of 65536 bits and operates asynchronously with a 5V nominal supply voltage range of 4.5V to 5.5V. The 24-pin Ceramic Dual In-line Package (CDIP) with a glass-sealed window allows for in-situ erasure. It features 3-state outputs, making it suitable for applications requiring parallel data access. The operating temperature range is -40°C to +85°C. This component finds application in industrial control systems, legacy equipment support, and embedded systems where non-volatile program storage is required and reprogrammability via UV light is a design consideration.
