48L512中文资料512 Kb SPI Serial EERAM数据手册Microchip规格书

描述 Description

EERAM is an SRAM that doesn't lose its content on a power disruption. Inside each memory cell, transparent to the user, are nonvolatile transistors that capture the SRAM content and hold it through power loss events. On power restore, the SRAM is reloaded with its last content and SRAM operation can continue.This product is no longer available. Please see EOL PCN# CAAN-21DKPT068

特性 Features

65,536 x 8 bit Serial SRAM with internal nonvolatile data backup
