Microchip Technology’s 27HC641-70I-K is a 64Kbit (8K x 8) CMOS UV Erasable Programmable Read-Only Memory (UVPROM) featuring a maximum access time of 70ns. This asynchronous device operates from a 4.5V to 5.5V supply, with a nominal 5V requirement. The 27HC641 series utilizes advanced CMOS technology for low standby and operating currents, with a maximum standby current of 50µA and a maximum supply current of 121mA. The component is housed in a 28-terminal Ceramic Chip Carrier (CQCC28) package with a square footprint and metal-sealed cofired construction, suitable for surface mounting applications. Its 3-state output characteristics allow for efficient bus sharing. The 27HC641-70I-K is engineered for applications demanding reliable, non-volatile program storage, including industrial control systems, telecommunications infrastructure, and legacy system upgrades. Its operating temperature range spans from -40°C to +85°C.
