Features

• 1-Mbit nonvolatile static random access memory (nvSRAM)
  • Internally organized as 128 K x 8
  • STORE to QuantumTrap nonvolatile elements initiated automatically on power-down (AutoStore) or by using I2C command (Software STORE) or HSB pin (Hardware STORE)
  • RECALL to SRAM initiated on power-up (Power Up RECALL) or by I2C command (Software RECALL)
  • Automatic STORE on power-down with a small capacitor
• High reliability
  • Infinite read, write, and RECALL cycles
  • 1 million STORE cycles to QuantumTrap
  • Data retention: 20 years at 85 °C

Overview

The Cypress CY14C101I/CY14B101I/CY14E101I combines a 1-Mbit nvSRAM[1] with a full-featured RTC in a monolithic integrated circuit with serial I2C 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. The SRAM provides infinite read and write cycles, while the QuantumTrap cells provide highly reliable nonvolatile storage of data. Data transfers from SRAM to the nonvolatile elements (STORE operation) takes place automatically at power-down.
