CY14B101Q2-LHXIT

1兆位（ 128K ×8 ）串行SPI的nvSRAM 1 Mbit 128K x 8 Serial SPI nvSRAM

Functional Overview

The Cypress CY14B101Q1/CY14B101Q2/CY14B101Q3 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.
