What are the key features of 23LC1024-E/SN?
- 1 Mbit (128 KB) serial SRAM with SPI, SDI, and SQI modes for flexible interface selection
- Up to 16 MHz clock frequency enabling fast data throughput in embedded data buffering applications
- SOIC-8 compact package with 2.5 V to 5.5 V supply range for broad MCU compatibility
What is 23LC1024-E/SN used for?
The 23LC1024-E/SN serves as an external data buffer or scratch-pad RAM for microcontrollers that lack sufficient on-chip SRAM for audio streaming, data logging, or display framebuffering tasks. Its SQI quad-interface mode allows throughput up to 4x standard SPI speeds, making it suitable for real-time data acquisition systems. Embedded networking equipment and IoT gateways also use it to temporarily store packet payloads before processing.

Frequently Asked Questions
What SPI clock speeds does the 23LC1024-E/SN support and how does that affect data throughput?
The 23LC1024-E/SN supports a maximum clock frequency of 16 MHz in SPI mode. In SQI mode, which uses all 4 I/O lines simultaneously, effective throughput reaches up to 8 MB/s, making it well suited for buffering audio streams or large sensor datasets in embedded systems.
How much memory does the 23LC1024-E/SN provide and what is the data organisation?
The device contains 1,048,576 bits (1 Mbit) organised as 131,072 bytes with an 8-bit wide data bus. This gives 128 KB of addressable SRAM, which is adequate for storing one full frame of a 128x64 monochrome OLED display or several seconds of 8-bit audio at 8 kHz.
When should a designer choose 23LC1024-E/SN over an internal SRAM expansion in a microcontroller?
The 23LC1024-E/SN is preferred when the target MCU has insufficient on-chip SRAM and adding a larger MCU would significantly increase cost or board area. Operating from 2.5 V to 5.5 V and housed in an 8-pin SOIC package, it integrates with minimal BOM impact, requiring only 4 to 6 signal lines and decoupling capacitors.
What is the factory lead time for the 23LC1024-E/SN and how should production planners account for it?
Microchip lists a 6-week factory lead time for the 23LC1024-E/SN. Production planners should place orders at least 8 to 10 weeks before the scheduled assembly date to account for shipping and incoming inspection. Authorised distributors frequently maintain safety stock to cover shorter-notice demand of up to a few thousand pieces.
