CY14E101Q2A-SXI
数据手册.pdfNVRAM NVSRAM Serial-SPI 1Mbit 5V 8Pin SOIC Tube
Functional Overview
The Cypress CY14X101Q combines a 1-Mbit nvSRAM with a nonvolatile element in each memory cell with serial SPI interface. The memory is organized as 128 K words of 8 bits each. The embedded nonvolatile elements incorporate the QuantumTrap technology, creating the world’s most reliable nonvolatile memory.
Features
