X20C16JI-55

The Xicor X20C16JI-55 is a 2K x 8 Non-Volatile RAM (NOVRAM) that combines a high-speed static RAM with a nonvolatile electrically erasable PROM (E2PROM). This integration is achieved through an overlaid bit-for-bit structure, enhanced by the AUTOSTORE feature which automatically saves RAM contents to E2PROM during power-down.

Fabricated using advanced CMOS floating gate technology, the X20C16JI-55 offers high speed with low power consumption and a wide power-supply margin. It supports access times of 35ns, 45ns, and 55ns, making it suitable for various applications requiring fast data access and nonvolatile storage.

The device features a JEDEC-approved pinout compatible with industry-standard RAMs, ROMs, EPROMs, and E2PROMs. It operates within a voltage range of -1V to +7V and has a maximum DC output current of 10mA. The NOVRAM is housed in a PLCC package, designed for reliability and low power operation.

Key features include power-on recall, software data protection, and infinite E2PROM array recall. The AUTOSTORE function ensures data integrity by automatically saving RAM data to E2PROM when a low VCC threshold is detected, providing a robust solution for data retention.
