What are the key features of 23LC1024T-I/SN?
- 1 Mbit (128 kB) serial SRAM with up to 20 MHz SPI clock for fast embedded data buffering
- Byte, page, and sequential access modes offer flexible read/write strategies for diverse firmware architectures
- Compact SOIC-8 package simplifies layout on space-constrained PCBs alongside microcontrollers
- Low standby current makes it suitable for battery-powered IoT devices requiring external data memory
What is 23LC1024T-I/SN used for?
The 23LC1024T-I/SN is ideal for embedded systems that require external RAM expansion beyond the microcontroller's internal SRAM, such as data loggers, communication buffers, and audio streaming buffers. Its SPI interface with up to 20 MHz clock speed pairs naturally with PIC, AVR, and ARM Cortex-M microcontrollers running at 3.3 V or 5 V. Industrial control panels and sensor networks use this device to store temporary measurement records or communication packets without needing a larger, more power-hungry parallel memory.

Frequently Asked Questions
How much storage capacity does 23LC1024T-I/SN provide and how is it accessed?
23LC1024T-I/SN provides 1 Mbit (128 kB) of SRAM organized as 131,072 bytes with 8-bit data width. Access is via a 4-wire SPI interface supporting byte, page, and sequential modes at up to 20 MHz clock, enabling fast burst reads and writes from any SPI-capable microcontroller.
In a data-logger design, how fast can 23LC1024T-I/SN transfer sensor samples over SPI?
At the maximum SPI clock of 20 MHz with 8-bit transfers, 23LC1024T-I/SN can sustain approximately 2.5 MB/s in sequential mode. This is fast enough to buffer hundreds of ADC samples per millisecond, preventing data loss on high-rate sensors such as vibration accelerometers or audio inputs operating at 44 kHz sample rates.
What package does 23LC1024T-I/SN use and what footprint does it require on a PCB?
23LC1024T-I/SN comes in an SOIC-8 package with 1.27 mm pitch and a body approximately 4.9 mm x 3.9 mm. This small 8-pin outline fits on standard 2-layer PCBs, requires only 4 signal traces (CS, SCK, SI, SO) plus power and ground, and leaves ample room for decoupling capacitors rated at 100 nF near the VCC pin.
When should a designer choose 23LC1024T-I/SN over a larger SPI flash for temporary data storage?
23LC1024T-I/SN is preferred when data must be overwritten frequently, since SRAM supports unlimited write cycles compared to the limited erase cycles of SPI flash (typically 100,000 cycles per sector). For circular buffers, DMA staging areas, and real-time variable storage needing byte-level random writes at up to 20 MHz, the 1 Mbit SRAM avoids flash wear-out entirely.
