23LC1024T-I/SN

Memory IC Overview

The Microchip Technology 23LC1024T-I/SN is a 1 Mbit Serial SRAM device organized as 128K x 8 bits. It features an SPI-compatible bus interface supporting SDI (dual) and SQI (quad) modes with a maximum clock frequency of 20 MHz. The component operates within a supply voltage range of 2.5V to 5.5V and supports industrial temperature grades from -40°C to +85°C. It utilizes low-power CMOS technology, offering unlimited read/write cycles and zero write time.

Memory IC Feature Summary

• Supports SPI, SDI, and SQI bus interfaces for flexible data transfer rates
• Provides unlimited read and write endurance cycles
• Features low standby current consumption for power efficiency
• Includes byte, page, and sequential operation modes

Memory IC Applications

• Microcontroller external memory expansion
• Data logging systems requiring high endurance
• Industrial control applications
• Embedded storage for real-time processing

Memory IC Procurement Notes

Verify the specific ordering suffix 'SN' corresponds to the SOIC-8 package and 'I' denotes the Industrial temperature grade (-40°C to +85°C). Confirm that the 'T' indicates tape and reel packaging if required by assembly equipment. Ensure compatibility with the host microcontroller's SPI voltage levels and timing requirements before finalizing procurement.

Memory IC Selection Notes

Select this component when a non-volatile solution is not required but high-speed random access and infinite write endurance are necessary. It serves as a direct replacement for parallel SRAM in space-constrained designs using serial interfaces. Consider the 23A1024 variant only if the application strictly requires a lower voltage range of 1.7V to 2.2V.

Memory IC Part Context

This part belongs to the 23LC1024 family of 1 Mbit Serial SRAMs manufactured by Microchip Technology. It is designed to interface directly with popular microcontroller families via standard serial protocols. The device offers a robust alternative to flash memory for applications demanding frequent data updates without wear-leveling constraints.

Memory IC Replacement Considerations

The 23A1024 is a functional substitute within the same family, differing primarily in its supported voltage range of 1.7V to 2.2V compared to the 2.5V to 5.5V range of the 23LC1024.
