Overview

The 23LC1024-I/SN is a 1 Mbit high-speed Serial SRAM with a wide operating voltage range from 2.5V to 5.5V. It utilizes a standard SPI interface and supports SDI and SQI modes for increased throughput, making it ideal for microcontrollers with limited internal RAM that require external memory expansion.

Why Choose This Part

This device offers unlimited endurance with zero write time, unlike EEPROM or Flash. The support for Quad I/O (SQI) allows for significantly higher data rates while maintaining a low pin-count 8-SOIC footprint and a low standby current of only 10 uA.

Applications

Audio Buffering
Provides volatile storage for digital audio streams or delay effects where low latency and unlimited read/write cycles are required.
Display Frame Buffers
Acts as an external buffer for small graphical displays, storing pixel data for microcontrollers that lack sufficient on-chip memory.
Sensor Data Logging
Used as a high-speed scratchpad to aggregate high-frequency sensor data before processing or batch-writing to non-volatile storage like SD cards.

Getting Started

Interface the device with a microcontroller using the SPI, SDI, or SQI bus. Ensure your firmware handles the volatile nature of the SRAM by initializing data on power-up. For rapid prototyping, use a standard SOIC-8 to DIP adapter on a breadboard with common MCU platforms like PIC, AVR, or STM32.
