M40Z300 NVRAM CONTROLLER for up to EIGHT LPSRAM

The M40Z300/W NVRAM Controller is a self-contained device which converts a standard low-power SRAM into a non-volatile memory. A precision voltage reference and comparator monitors the VCC input for an out-of-tolerance condition. VSS B *(1) NOTE: 1. For 16-pin SOIC package only. AI02242 Mar.
