23LCV512T-I/SN

Memory IC Overview

The Microchip Technology 23LCV512T-I/SN is a 512-Kbit Serial Static Random Access Memory (SRAM) device. It features an SPI-compatible bus interface with support for Dual I/O (SDI) mode, operating at clock frequencies up to 20 MHz. The memory organization is 64K x 8 bits. It supports a supply voltage range of 2.5V to 5.5V and operates within an industrial temperature range of -40°C to +85°C. The device is housed in an 8-lead Thin Shrink Small Outline (TSSOP) package.

Memory IC Feature Summary

• Supports external battery backup via VBAT pin to maintain data during power loss
• Enables unlimited read and write cycles without wear-out limitations
• Offers flexible access modes including Byte, Page, and Sequential operations
• Provides low-power CMOS technology with standby current reduction capabilities

Memory IC Applications

• Data logging systems requiring non-volatile-like retention via battery backup
• Microcontroller-based embedded systems needing fast random access memory
• Industrial control applications operating in extended temperature environments
• Battery-powered devices utilizing low standby current consumption

Memory IC Procurement Notes

Verify the specific ordering suffix 'T' indicates tape and reel packaging when sourcing this component. Confirm the 'I' suffix corresponds to the industrial temperature grade (-40°C to +85°C). Ensure the 'SN' designation matches the required 8-lead TSSOP package type for your PCB layout. Cross-reference the datasheet revision B for updated terminology and package drawings.

Memory IC Selection Notes

Select this component when an SPI interface is preferred over parallel buses for space-constrained designs. Choose the 23LCV512T-I/SN specifically for its TSSOP footprint requirements. Consider the SDI capability if higher data throughput is needed compared to standard SPI. Evaluate the battery backup feature necessity against alternative non-volatile memory solutions.

Memory IC Part Context

This part belongs to the 23LCV512 family of serial SRAMs from Microchip Technology. It shares functional similarities with other members like the 23LCV512-I/SN but differs in packaging format. The series is designed to interface directly with popular microcontroller families, offering a drop-in replacement for volatile memory applications where data retention via external backup is required.

Memory IC Replacement Considerations

Direct substitutes include other variants within the 23LCV512 family such as the 23LCV512-I/SN or 23LCV512-I/P, provided the package difference is accommodated. Verify compatibility with existing firmware regarding SPI command sets and timing parameters before substitution.
