23LCV1024T-I/SN

Memory IC Overview

The Microchip Technology 23LCV1024T-I/SN is a 1 Mbit Serial SRAM device housed in an 8-lead SOIC package. It features a SPI-compatible bus interface with a maximum clock frequency of 20 MHz and supports SDI mode for dual I/O operations. The memory organization is 128K x 8 bits, operating within a supply voltage range of 2.5 V to 5.5 V. Designed for industrial applications, it functions reliably across a temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports external battery backup via the VBAT pin to maintain data during power loss
• Enables unlimited read and write cycles without write time delays
• Offers flexible access modes including Byte, Page, and Sequential operations
• Integrates low-power CMOS technology for reduced standby current consumption

Memory IC Applications

• Data logging systems requiring persistent storage
• Microcontroller-based embedded designs needing fast non-volatile-like access
• Industrial control units with intermittent power availability
• IoT edge devices utilizing serial communication interfaces

Memory IC Procurement Notes

Verify that the ordering suffix 'SN' corresponds specifically to the 8-lead SOIC package variant. Confirm the 'I' designation indicates the industrial temperature range of -40°C to +85°C. Ensure compatibility with the required SPI or SDI interface protocols before integration into the design.

Memory IC Selection Notes

Select this component when a small footprint serial SRAM with battery backup capabilities is required. It is suitable for designs needing high-speed access up to 20 MHz while maintaining low power consumption. Consider the 8-lead SOIC package constraints and verify that the 2.5 V to 5.5 V supply range aligns with the system power architecture.

Memory IC Part Context

This part belongs to the 23LCV1024 family of 1 Mbit Serial SRAMs from Microchip Technology. The family includes variants with different packages such as TSSOP and PDIP, and options like the 23LC1024 which supports a wider voltage range. The 23LCV1024 series is specifically optimized for lower voltage operation starting at 2.5 V.

Memory IC Replacement Considerations

Direct substitutes include other parts within the 23LCV1024 family with different package suffixes, such as 23LCV1024T-I/ST (TSSOP) or 23LCV1024-I/P (PDIP). Cross-family replacements like the 23LC1024 offer similar functionality but may differ in voltage specifications.
