23LCV512T-E/SN

Memory IC Overview

The Microchip Technology 23LCV512T-E/SN is a 512-Kbit Serial SRAM device featuring an SPI-compatible bus interface with support for SDI (Serial Dual Interface) mode. It operates within a supply voltage range of 2.5V to 5.5V and supports clock frequencies up to 20 MHz. The memory organization is 64K x 8 bits, structured in 32-byte pages. The component includes an external battery backup input (VBAT) to maintain data retention when VCC falls below the trip point. It is available in an 8-lead SOIC package.

Memory IC Feature Summary

• Supports unlimited read and write cycles without write time delays.
• Features an external battery backup pin (VBAT) for data retention during power loss.
• Compatible with standard SPI protocols and offers dual I/O access via SDI mode for increased throughput.
• Provides byte, page, and sequential operation modes for flexible data access.

Memory IC Applications

• Microcontroller systems requiring non-volatile-like data storage with high-speed random access.
• Industrial control applications utilizing industrial temperature grade components.
• Embedded systems needing fast data logging or buffer storage with battery-backed integrity.

Memory IC Procurement Notes

Verify that the ordering suffix 'E' corresponds to the Extended temperature range (-40°C to +125°C) as specified in the manufacturer's selection table, distinct from the Industrial range. Confirm the 'SN' suffix indicates the 8-lead SOIC package type. Ensure the datasheet revision matches the required specifications for your design implementation.

Memory IC Selection Notes

Select this component when high-speed volatile storage is needed alongside battery backup capabilities. Compare against EEPROM options if write endurance is critical, noting SRAM offers zero write time. Consider the SDI interface requirement if higher data rates are necessary compared to standard SPI-only devices.

Memory IC Part Context

The 23LCV512 belongs to Microchip's family of serial SRAM devices designed for direct interfacing with microcontrollers. It serves as a high-performance alternative to parallel SRAMs by reducing pin count through serial communication. The device integrates seamlessly into systems requiring rapid data acquisition and preservation.

Memory IC Replacement Considerations

Check for 23LCV512-I/SN if Industrial temperature range (-40°C to +85°C) suffices. Verify compatibility with 23LC512 variants regarding interface modes and voltage levels before substitution.
