Memory IC datasheet and documents for 23K640T-I/SN

23K640T-I/SN

Memory IC Overview

The Microchip Technology 23K640T-I/SN is a 64-Kbit (8192 x 8-bit) low-power CMOS Serial SRAM accessed via an SPI-compatible bus. It operates within a supply voltage range of 2.7V to 3.6V and supports clock frequencies up to 20 MHz. The device features a 32-byte page size and includes a HOLD pin for pausing serial communication. It is housed in an 8-lead SOIC package and supports industrial temperature ranges from -40°C to +85°C.

Memory IC Feature Summary

Supports flexible operating modes including byte, page, and sequential read/write operations.
Includes a dedicated HOLD input pin to suspend transmission without resetting the sequence.
Features low-power CMOS technology with defined standby and active current consumption levels.
Provides access to a STATUS register for configuring device operating modes.

Memory IC Applications

Data logging systems requiring non-volatile-like temporary storage.
Microcontroller-based embedded designs needing fast random access memory.
Industrial control applications utilizing SPI interfaces.
Automotive electronics compliant with AEC-Q100 standards.

Memory IC Procurement Notes

Verify that the ordering suffix 'I' corresponds to the Industrial temperature range (-40°C to +85°C) and 'SN' indicates the 8-lead SOIC package. Confirm the 'T' suffix denotes tape and reel packaging if required for automated assembly. Ensure the specific variant matches the 2.7V to 3.6V supply voltage requirement for the 23K640 series.

Memory IC Selection Notes

Select this component when an SPI interface is preferred over parallel buses to save I/O pins. Choose the 23K640T-I/SN specifically for its 64-Kbit capacity and 32-byte page mode efficiency. Consider the automotive-grade E-temperature variant if operation up to +125°C is necessary instead of the standard industrial range.

Memory IC Part Context

This part belongs to the 23X640 family of 64-Kbit Serial SRAMs manufactured by Microchip Technology. The family includes variants like the 23A640 which operates at lower voltages (1.5V to 1.95V). The 23K640 series is designed for high reliability and offers multiple package options including PDIP, SOIC, and TSSOP.
