Overview

The 23LCV1024-I/SN is a 1 Mbit Serial SRAM from Microchip Technology designed for high-speed data buffering and temporary storage. It operates across a wide voltage range of 2.5V to 5.5V and features an integrated battery backup pin to maintain data integrity during power loss. Unlike standard Flash or EEPROM, this SRAM offers unlimited read and write cycles with zero write time.

Why Choose This Part

The device supports SPI and Dual SPI (SDI) modes at clock speeds up to 20 MHz, providing high throughput for 8-pin serial interfaces. Its standby current of only 4 uA makes it ideal for battery-powered applications requiring long-term data retention. The primary engineering advantage is the combination of SRAM speed with the persistent nature of battery-backed memory in a compact SOIC-8 package.

Applications

Non-Volatile Data Logging
Using the VBAT pin to connect a small battery or supercapacitor for keeping critical system state data alive during power outages.
Audio Buffering
Handling real-time audio streams where high-speed serial access and zero latency are required for signal processing.
Scratchpad Memory
Providing additional RAM for resource-constrained microcontrollers during complex math operations or display buffer management.

Getting Started

To interface with this device, connect the SPI bus (SCK, SI, SO, CS) to your MCU and provide a 2.5V-5.5V supply to VDD. If data retention is required, connect a 3V coin cell to the VBAT pin; if not, VBAT should be tied to ground. Microchip provides C libraries through MPLAB Code Configurator (MCC) for easy integration with PIC and AVR microcontrollers.
