23LCV1024-I/ST

Memory IC Overview

The Microchip Technology 23LCV1024-I/ST is a 1 Mbit (128K x 8-bit) Serial SRAM device housed in an 8-lead TSSOP package. It operates within a supply voltage range of 2.5V to 5.5V and supports a maximum clock frequency of 20 MHz via a SPI-compatible interface. The component features low-power CMOS technology with a standby current of 4 µA at +85°C. It includes an external battery backup input (VBAT) for data retention when VCC falls below the trip point, ensuring unlimited read and write cycles.

Memory IC Feature Summary

• Supports SPI and SDI bus interfaces for flexible communication protocols
• Enables data preservation through external battery backup connection
• Provides unlimited read and write cycle endurance

Memory IC Applications

• Microcontroller system memory expansion
• Real-time data buffering in embedded systems
• Industrial control applications requiring non-volatile-like data retention

Memory IC Procurement Notes

Verify that the ordering suffix 'ST' corresponds to the TSSOP-8 package variant required for your design. Confirm the industrial temperature grade 'I' (-40°C to +85°C) matches your environmental specifications. Ensure the 2.5V to 5.5V operating voltage aligns with your system power rails. Check for RoHS compliance requirements if applicable to your manufacturing standards.

Memory IC Selection Notes

Select this component when a 1 Mbit serial SRAM solution is needed with SPI compatibility. It is suitable for designs requiring high-speed random access without the refresh overhead of DRAM. Consider the VBAT pin functionality if battery-backed data retention is necessary during power transitions. Verify that the TSSOP-8 footprint fits your PCB layout constraints.
