23LCV02M-I/SL

Memory IC Overview

The Microchip Technology 23LCV02M-I/SL is a 2-Mbit (256K x 8-bit) serial static random-access memory device housed in a 14-lead TSSOP package. It operates within a supply voltage range of 2.2V to 3.6V and supports an industrial temperature range of -40°C to +85°C. The device features SPI, SDI, and SQI interface compatibility with a maximum clock frequency of 143 MHz. Key specifications include a standby current of 70 µA typical at 25°C, unlimited read/write cycles, and built-in error correction code logic for enhanced reliability.

Memory IC Feature Summary

• Supports external battery backup via the VBAT pin to maintain data when VCC drops below the trip point.
• Includes built-in Error Correction Code (ECC) logic to ensure superior data reliability during read operations.
• Offers flexible page size configuration allowing selection between 32-byte or 256-byte pages.
• Enables high-speed data transfer through Serial Dual Interface (SDI) and Serial Quad Interface (SQI) modes.

Memory IC Applications

• Data logging systems requiring non-volatile retention capabilities
• Embedded control applications needing fast serial access
• Industrial monitoring devices operating in harsh environments

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the 14-lead TSSOP package variant. Confirm the voltage range requirement matches the 2.2V minimum threshold specified for the 23LCV02M series, distinct from the 23AA02M series. Ensure the industrial temperature grade aligns with system operational constraints. Cross-reference the datasheet revision to confirm pinout consistency for the SL package type.

Memory IC Selection Notes

Select this component when battery-backed SRAM functionality is required alongside high-speed serial communication. The 23LCV02M is suitable for designs needing unlimited write endurance compared to EEPROM alternatives. Consider the SQI mode if higher throughput is necessary without increasing pin count. Verify that the host controller supports the required SPI modes and command sets for ECC status reading.

Memory IC Part Context

This part belongs to the 23XX02M family of 2-Mbit serial SRAMs manufactured by Microchip Technology. It shares architectural similarities with the 23AA02M but differs in voltage range and battery backup support. The family utilizes a standard SPI-compatible bus protocol while offering optional dual and quad I/O enhancements for performance scaling.
