93LC86AT-I/OT

Memory IC Overview

The Microchip Technology 93LC86AT-I/OT is a 16K bit low-voltage serial Electrically Erasable PROM (EEPROM) utilizing advanced CMOS technology. It features a dedicated 2048 x 8-bit memory organization and operates within a supply voltage range of 2.5V to 5.5V. The device supports an industry-standard 3-Wire Microwire compatible serial interface with a maximum clock frequency of 3 MHz. Designed for industrial applications, it functions reliably across a temperature range of -40°C to +85°C and is housed in a compact 6-lead SOT-23 surface-mount package.

Memory IC Feature Summary

• Low-power CMOS construction suitable for nonvolatile memory applications
• Microwire compatible 3-wire serial input/output interface
• Self-timed erase/write cycles with automatic erase before write all operations
• Power-on/off data protection circuitry prevents accidental data disturbance

Memory IC Applications

• Industrial control systems requiring persistent parameter storage
• Consumer electronics needing configuration data retention
• Automotive modules operating within specified temperature ranges
• Embedded devices storing calibration or identification information

Memory IC Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +85°C) and 'OT' denotes the SOT-23-6 package. Confirm RoHS compliance and lead-free status as per current manufacturing standards. Ensure the ordering code matches the exact 8-bit organization requirement, as other variants in the family may offer different word sizes or voltage ranges.

Memory IC Selection Notes

Select this component when a fixed 8-bit word width is required without external configuration pins. Compare against 93LC86BT variants if 16-bit organization is needed, or 93LC86C models if programmable organization via the ORG pin is desired. Consider the 93AA86A series only if operation below 2.5V is necessary, as the LC variant requires a minimum of 2.5V.

Memory IC Part Context

This part belongs to the 93XX86A/B/C family of 16K bit serial EEPROMs from Microchip Technology. The 'LC' designation indicates a 2.5V to 5.5V operating range, distinguishing it from the lower voltage AA series and higher voltage C series. The 'A' suffix specifies a fixed 8-bit organization, unlike the B (16-bit) or C (selectable) versions.

Memory IC Replacement Considerations

Direct functional substitutes include the 93LC86BT-I/OT for 16-bit organization needs or the 93LC86C-I/OT for configurable word size. Verify that any replacement maintains the same SOT-23-6 footprint and industrial temperature rating.
