23LCV1024-I/P

Memory IC Overview

The Microchip Technology 23LCV1024-I/P is a 1 Mbit Serial Static Random Access Memory (SRAM) device housed in an 8-lead PDIP package. It operates within a supply voltage range of 2.5 V to 5.5 V and supports industrial temperature conditions from -40°C to +85°C. The device features a SPI-compatible bus interface with a maximum clock frequency of 20 MHz and includes support for SDI (Serial Dual Interface) mode. It offers unlimited read/write cycles, zero write time, and external battery backup capability via the VBAT pin.

Memory IC Feature Summary

• Supports SPI and SDI interfaces for flexible data transfer rates
• Enables external battery backup to maintain memory contents during power loss
• Provides unlimited read and write endurance without write delay
• Operates across a wide voltage range suitable for various logic levels

Memory IC Applications

• Data logging systems requiring persistent storage
• Industrial control applications needing reliable non-volatile-like SRAM
• Embedded systems interfacing with microcontrollers via SPI
• Battery-backed memory solutions for critical data retention

Memory IC Procurement Notes

Verify that the specific part number matches the required voltage range and package type. Confirm the temperature grade aligns with your operational environment. Ensure compatibility with your system's SPI controller settings, particularly regarding SDI mode if utilized. Check for any specific ordering suffixes that might affect packaging or lead times.

Memory IC Selection Notes

Select this component when a high-density serial SRAM with battery backup is required. It is suitable for applications needing fast random access without the wear leveling complexity of flash memory. Consider the PDIP package for through-hole mounting requirements. Evaluate the need for SDI mode to determine if dual I/O lines are necessary for increased throughput.

Memory IC Part Context

This device belongs to the 23LCV series of serial SRAMs from Microchip Technology. It is designed as a drop-in replacement for parallel SRAMs in many applications, reducing pin count and board space. The 'I' designation indicates the industrial temperature range, while '/P' specifies the PDIP package style.

Memory IC Replacement Considerations

Direct replacements include other 23LCV1024 variants with different packages such as SOIC or TSSOP. Cross-referencing with similar capacity serial SRAMs from other manufacturers requires careful verification of pinouts, voltage levels, and command sets.
