23A1024-E/P

Memory IC Overview

The Microchip Technology 23A1024-E/P is a 1 Mbit Serial SRAM device organized as 128K x 8 bits. It operates within a supply voltage range of 1.7 V to 2.2 V and supports an automotive temperature range from -40°C to +125°C. The component utilizes SPI, SDI, and SQI interfaces with a maximum clock frequency of 16 MHz for the E-temp grade. It features a PDIP-8 package and includes byte, page, and sequential read/write modes.

Memory IC Feature Summary

• Supports unlimited read and write cycles with zero write time
• Compatible with SPI, Dual I/O (SDI), and Quad I/O (SQI) bus protocols
• Includes HOLD functionality to suspend serial communication sequences

Memory IC Applications

• Automotive embedded systems requiring extended temperature operation
• Microcontroller data storage via SPI interface
• Low-power battery-operated devices utilizing standby mode

Memory IC Procurement Notes

Verify that the specific ordering suffix 'P' corresponds to the PDIP-8 through-hole package configuration. Confirm the 'E' designation aligns with the required automotive temperature range of -40°C to +125°C. Ensure the voltage rating matches the 1.7V to 2.2V specification for the 23A series variant rather than the 23LC series.

Memory IC Selection Notes

Select this component when an automotive-grade environment necessitates operation up to +125°C. Choose the 23A1024 over the 23LC1024 if the system design operates on lower voltages between 1.7V and 2.2V. Verify that the host microcontroller supports the desired serial interface mode, whether standard SPI or higher-speed SDI/SQI.

Memory IC Part Context

This part belongs to the 23A1024/23LC1024 family of 1 Mbit Serial SRAMs manufactured by Microchip Technology. The 23A series specifically targets applications requiring wider temperature ranges and lower operating voltages compared to the standard 23LC series. It provides non-volatile-like persistence during power while offering high-speed random access capabilities.

Memory IC Replacement Considerations

The 23LC1024 serves as a functional substitute if the application voltage exceeds 2.2V and the operating temperature remains within industrial limits (-40°C to +85°C). Verify pin compatibility and ensure the replacement meets the specific voltage and thermal requirements of the target circuit.
