Microchip Technology's 27HC641-70B-UX is a 65536-bit (8K x 8) UV erasable programmable read-only memory (UVPROM) utilizing high-speed CMOS technology. This asynchronous device offers a maximum access time of 70ns, making it suitable for demanding applications. The 27HC641 series component is housed in a 28-lead ceramic quad flat pack (CQFP), with a square package style and JEDEC S-XQCC-N28 designation. It operates over a wide temperature range of -55°C to +125°C and features 3-state outputs for flexible system integration. Typical applications include industrial controls, telecommunications infrastructure, and data acquisition systems where robust, non-volatile code storage is essential. The component supports a nominal supply voltage of 5V and exhibits a maximum supply current of 90mA.
