What are the key features of 23LCV1024-I/P?

1 Mbit (128 KB x 8) serial SRAM with 20 MHz SPI clock enabling fast random and sequential access in 8-bit data width
Supports SPI, SDI, and SQI modes allowing the user to switch between 1-bit, 2-bit, and 4-bit I/O for higher throughput
Battery-backed data retention with separate VCC and VCAP pins preserving 128 KB of SRAM contents during power interruptions

What is 23LCV1024-I/P used for?

The 23LCV1024-I/P is used as an external data buffer and logging memory in embedded microcontroller systems where the internal SRAM is insufficient for temporary data storage. It is well suited for audio sample buffers, data logging in industrial sensors, and network packet buffering in 8-bit MCU designs that already have an SPI bus, adding 128 KB of fast random-access storage without the address/data bus overhead of parallel SRAM.

Frequently Asked Questions

What is the total memory capacity of 23LCV1024-I/P and how is it organized for SPI access?

The 23LCV1024-I/P provides 1 Mbit of SRAM organized as 128 KB x 8 bits, accessed via a serial SPI interface at up to 20 MHz clock frequency. Both random byte access and sequential page-mode reads are supported, enabling efficient burst transfers of large data blocks from an embedded microcontroller within a few microseconds per 128-byte page.

How does the dual-supply architecture of 23LCV1024-I/P help retain data during a power loss event?

The 23LCV1024-I/P has separate VCC and VCAP supply pins, allowing a small capacitor or battery on VCAP to hold the SRAM array contents even when the main VCC supply is removed. This battery-backed retention feature preserves all 128 KB of stored data across power cycles, eliminating the need for an external flash write cycle and the associated latency in data-logging or state-save applications.

In what scenario is 23LCV1024-I/P a better expansion choice than an I2C EEPROM for a microcontroller data buffer?

When a microcontroller needs to buffer large blocks of data at high update rates — such as capturing 1000 sensor samples per second or streaming 16-bit audio — the 23LCV1024-I/P 20 MHz SPI interface provides far greater bandwidth than an I2C EEPROM limited to 400 kHz or 1 MHz. SRAM also offers unlimited write cycles, unlike EEPROM limited to typically 1 million writes per cell, making it more suitable for high-frequency logging applications.
