Memory IC datasheet and documents for 93LC46AT-I/ST

93LC46AT-I/ST

Memory IC Overview

The Microchip Technology 93LC46AT-I/ST is a 1Kbit low-voltage serial Electrically Erasable PROM (EEPROM) utilizing advanced CMOS technology. It features a fixed 128 x 8-bit organization and operates on an industry-standard 3-wire Microwire serial interface. The device supports a maximum clock frequency of 3 MHz at VCC levels between 4.5V and 5.5V, with reduced speeds at lower voltages. It includes power-on/off data protection circuitry and automatic erase/write cycles.

Memory IC Feature Summary

Low-power CMOS construction for nonvolatile memory applications
Self-timed erase and write cycles with automatic Erase All before Write All
Power-on/off data protection to prevent accidental programming
Ready/Busy status signal output via the Data Out pin

Memory IC Applications

Low-power nonvolatile memory storage
Industrial control systems requiring serial EEPROM
Automotive electronics operating in extended temperature ranges

Memory IC Procurement Notes

Verify that the ordering suffix 'I' confirms the Industrial temperature range (-40°C to +85°C). Confirm the 'ST' suffix corresponds to the 8-lead TSSOP package. Ensure the specific part number matches the required 128 x 8-bit organization, as other variants in the series may offer different word sizes or voltage ranges.

Memory IC Selection Notes

Select this component when a dedicated 8-bit word size is required without an external ORG pin configuration. Compare against 93LC46B variants if 16-bit words are needed. Verify that the 2.5V to 5.5V supply range aligns with the system design, noting that higher clock frequencies require VCC above 4.5V.

Memory IC Part Context

This device belongs to the 93XX46A/B/C family of 1Kbit serial EEPROMs from Microchip Technology. The 'LC' designation indicates a 2.5V minimum operating voltage, distinguishing it from the 1.8V capable 'AA' series and the 4.5V minimum 'C' series. The 'A' variant provides a fixed 8-bit organization.
