What are the key features of 23LCV1024-I/ST?
- 1 Mbit (128K x 8-bit) SPI SRAM with battery-backed data retention for non-volatile RAM applications
- Up to 20 MHz SPI clock frequency enables fast serial read and write access in embedded systems
- Separate I/O architecture supports full-duplex SPI communication for high-speed data buffering
- TSSOP-8 package minimizes PCB footprint while providing low standby current for battery-powered designs
What is 23LCV1024-I/ST used for?
The 23LCV1024-I/ST is ideal for data logging, configuration storage, and circular buffer applications in embedded systems where battery-backed SRAM provides instant read/write access without the write endurance limits of Flash or EEPROM. Its SPI interface at 20 MHz makes it a drop-in serial RAM solution for microcontrollers in IoT gateways, industrial data recorders, and metering systems requiring fast, non-volatile byte-addressable storage. The compact TSSOP-8 package suits space-constrained PCB designs in handheld instruments and wearable electronics.

Frequently Asked Questions
What SPI clock frequency does the 23LCV1024-I/ST support and how does this affect data throughput?
The 23LCV1024-I/ST supports SPI clock frequencies up to 20 MHz, enabling read and write throughput of approximately 2.5 MB/s in standard SPI mode. This is sufficient for real-time data logging at 10 kHz sample rates across 8-bit or 16-bit channels without introducing acquisition gaps in embedded data recorder designs.
How does the battery-backed retention feature of the 23LCV1024-I/ST differ from standard SRAM or EEPROM?
Unlike standard volatile SRAM that loses data on power removal, the 23LCV1024-I/ST retains all 128K x 8-bit of stored data when a backup battery is connected to the VCAP pin. Unlike EEPROM, it has no write endurance limit per byte, making it suitable for high-frequency circular buffer applications where millions of write cycles would degrade EEPROM cells.
For a microcontroller-based data logger, when is 23LCV1024-I/ST preferable to an I2C EEPROM?
When data must be written at kilobyte-per-second rates with random byte addressing, 23LCV1024-I/ST's 20 MHz SPI interface and SRAM write speed outperform I2C EEPROM devices limited to 400 kHz and page-write delays of 5-10 ms. The absence of write endurance limits also makes it more reliable for continuous logging applications that would exhaust an EEPROM's 1 million cycle rating.
What is the memory capacity of the 23LCV1024-I/ST and how does the TSSOP-8 package constrain its use cases?
The 23LCV1024-I/ST provides 1 Mbit (1,048,576 bits) of SRAM organized as 131,072 bytes (128K x 8 bits). The TSSOP-8 package measures approximately 3 mm x 4.4 mm, making it suitable for densely populated PCBs but requiring SMD assembly with fine-pitch soldering equipment, which may limit its use in hand-assembled prototyping contexts.
