23LC1024-I/P

Memory IC Overview

The Microchip Technology 23LC1024-I/P is a 1 Mbit Serial Static Random Access Memory (SRAM) device. It features a 128K x 8-bit organization and supports SPI, SDI, and SQI interfaces with a maximum clock frequency of 16 MHz for the E-temp grade or 20 MHz for I-temp. The component operates within a supply voltage range of 2.5 V to 5.5 V and functions across an industrial temperature range of -40°C to +85°C. It utilizes low-power CMOS technology and is housed in an 8-lead PDIP package.

Memory IC Feature Summary

• Supports SPI, SDI, and SQI bus interfaces for flexible data transfer rates
• Provides unlimited read and write cycles with zero write time
• Operates on low-power CMOS technology with standby current as low as 4 µA at +85°C
• Includes Byte, Page, and Sequential modes for efficient memory access

Memory IC Applications

• Microcontroller system expansion requiring non-volatile-like persistent storage
• Data logging applications needing fast random access capabilities
• Embedded systems utilizing SPI-compatible communication protocols
• Industrial control units operating within extended temperature ranges

Memory IC Procurement Notes

Verify the specific suffix 'I' confirms the Industrial temperature range (-40°C to +85°C). Confirm the 'P' suffix indicates the 8-lead PDIP through-hole package. Ensure the source documentation explicitly lists the 23LC1024-I/P part number to validate the 2.5V to 5.5V voltage range specifications before procurement.

Memory IC Selection Notes

Select this component when a microcontroller requires additional high-speed volatile memory accessible via standard serial lines. The 23LC1024-I/P is suitable for designs needing robust industrial temperature performance and through-hole mounting. Consider the 16 MHz limit if using the Automotive grade, though this specific part is Industrial rated.

Memory IC Part Context

This device belongs to the 23LC1024 family of 1 Mbit Serial SRAMs manufactured by Microchip Technology. It shares architectural similarities with the 23A1024 but differs in its wider operating voltage range. The series is designed to interface directly with popular microcontroller families, offering a cost-effective alternative to parallel SRAM solutions while maintaining high-speed data throughput.

Memory IC Replacement Considerations

The 23LC1024-I/SN and 23LC1024-I/ST are functionally equivalent alternatives offering different package types (SOIC and TSSOP respectively) while maintaining the same electrical characteristics and pinout compatibility.
