Memory IC datasheet and documents for 93LC46CT-E/MS

93LC46CT-E/MS

Memory IC Overview

The Microchip Technology 93LC46CT-E/MS is a 1Kbit low-voltage serial Electrically Erasable PROM (EEPROM) utilizing advanced CMOS technology. It features a 64 x 16-bit memory organization and operates within a supply voltage range of 2.5V to 5.5V. The device supports a maximum clock frequency of 2 MHz and offers data retention exceeding 200 years with 1,000,000 erase/write cycles endurance. Designed for industrial applications, it functions reliably across temperatures from -40°C to +85°C and is housed in an 8-lead MSOP package.

Memory IC Feature Summary

Supports industry-standard 3-Wire Microwire serial interface for communication
Includes power-on/off data protection circuitry to prevent corruption
Features self-timed erase and write cycles with automatic ready/busy status signaling

Memory IC Applications

Low-power nonvolatile memory storage
Industrial control systems requiring reliable data retention
Embedded devices needing compact serial EEPROM solutions

Memory IC Procurement Notes

Verify the specific suffix 'E' corresponds to the Automotive temperature grade (-40°C to +125°C) if required, as datasheet tables list 'I' for Industrial and 'E' for Automotive ranges. Confirm the 'T' suffix indicates tape-and-reel packaging rather than tube. Ensure the 'C' designation matches the 64x16 organization requirement, distinct from dedicated A or B versions.

Memory IC Selection Notes

Select this component when a fixed 16-bit word size is necessary, unlike the 'C' version which allows configuration via the ORG pin. Choose the MSOP package for space-constrained surface-mount designs. Verify that the 2.5V minimum operating voltage aligns with the system's power rails, as lower voltage variants exist within the broader series.

Memory IC Part Context

This part belongs to the 93XX46A/B/C family of 1Kbit Microwire compatible serial EEPROMs. The 'LC' variant specifically denotes operation at lower voltages starting at 2.5V, distinguishing it from the 'AA' (1.8V start) and 'C' (4.5V start) sub-series. The 'B' designation confirms the hardware-fixed 16-bit organization without an external configuration pin.
