Features & Applications

The ON Semiconductor serial SRAM family includes several integrated memory devices including this 256 Kb serially accessed Static Random Access Memory, internally organized as 32 K words by 8 bits. The devices are designed and fabricated using ON Semiconductor’s advanced CMOS technology to provide both high−speed performance and low power.

The devices operate with a single chip select (CS) input and use a simple Serial Peripheral Interface (SPI) serial bus. A single data in and data out line is used along with a clock to access data within the devices. The N25S830HA devices include a HOLD pin that allows communication to the device to be paused. While paused, input transitions will be ignored. The devices can operate over a wide temperature range of −40°C to +85°C and can be available in several standard package offerings.

Key Features:

  • Power Supply Range: 2.7 to 3.6 V

  • Flexible Operating Modes:
    • Word read and write
    • Page mode (32 word page)
    • Burst mode (full array)
  • Organization: 32 K x 8 bit
  • Self Timed Write Cycles
  • Built−in Write Protection (CS High)
  • HOLD Pin for Pausing Communication
  • High Reliability: Unlimited write cycles
  • Green SOIC and TSSOP
  • These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS Compliant
