23LCV1024T-E/SN

Memory IC Overview

The Microchip Technology 23LCV1024T-E/SN is a 1 Mbit (128K x 8) Serial Static Random Access Memory device. It operates within a supply voltage range of 2.5 V to 5.5 V and supports clock frequencies up to 20 MHz via an SPI-compatible bus interface. The component features low-power CMOS technology with standby current as low as 4 µA at +85°C. It includes an external battery backup input (VBAT) for data retention when the main power supply drops below the trip point. The device is housed in an 8-lead SOIC package and supports industrial temperature ranges from -40°C to +85°C.

Memory IC Feature Summary

• Supports external battery backup via VBAT pin to maintain SRAM data during power loss
• Enables dual I/O access through SDI mode for increased data transfer rates
• Provides unlimited read and write cycles without wear-out limitations
• Operates with zero write time, eliminating traditional write cycle delays

Memory IC Applications

• Data logging systems requiring persistent storage during power interruptions
• Embedded microcontroller applications needing fast non-volatile-like memory access
• Industrial control systems operating in harsh environmental conditions
• Battery-powered devices utilizing backup power supplies for critical data retention

Memory IC Procurement Notes

Verify that the ordering suffix correctly identifies the SN package type and E temperature grade. Confirm compatibility with the specific SPI controller or master device intended for use. Ensure the design accounts for the VBAT pin requirements if battery backup functionality is utilized. Check for any recent Product Change Notifications regarding assembly sites or packaging updates.

Memory IC Selection Notes

Select this component when high-speed serial access is required alongside data retention capabilities during power failures. Consider the 23LCV1024T-E/SN for designs necessitating surface-mount integration with specific thermal performance characteristics. Evaluate the need for SDI mode support to optimize bandwidth compared to standard SPI operations. Compare against other series members based on voltage range and package availability constraints.

Memory IC Part Context

This part belongs to the 23LCV1024 family of 1 Mbit Serial SRAMs manufactured by Microchip Technology. The family shares core architectural features but varies in operating voltage, temperature grades, and physical packaging options. The 'T' indicates tape and reel packaging, while 'SN' specifies the 8-lead SOIC form factor. The 'E' suffix denotes the extended industrial temperature rating.

Memory IC Replacement Considerations

Direct substitutes include other variants within the 23LCV1024 family such as the 23LCV1024-I/SN or 23LCV1024-E/ST, provided package and temperature specifications align. Cross-referencing with the 23LC512 or 23A1024 series may be necessary if capacity or voltage requirements differ. Verify pinout compatibility before substituting.
