93LC56BT-I/MNY

Memory IC Overview

The Microchip Technology 93LC56BT-I/MNY is a 2Kbit serial Electrically Erasable PROM (EEPROM) utilizing low-power CMOS technology. It features a fixed 128 x 16-bit organization and operates within a supply voltage range of 2.5V to 5.5V. The device supports an industry-standard 3-Wire Microwire interface with a maximum clock frequency of 2 MHz in the industrial temperature range (-40°C to +85°C). It offers 1,000,000 erase/write cycles and data retention exceeding 200 years.

Memory IC Feature Summary

• Self-timed erase and write cycles with automatic Erase All before Write All functionality
• Power-on/off data protection circuitry prevents accidental programming during power transitions
• Ready/Busy status signal output for monitoring programming completion
• Sequential read capability allows continuous data retrieval without re-selecting addresses

Memory IC Applications

• Low-power nonvolatile memory storage
• Industrial control systems requiring robust data retention
• Embedded applications needing small capacity configuration storage
• Automotive electronics operating in extended temperature ranges

Memory IC Procurement Notes

Verify that the ordering suffix 'MN' corresponds to the TDFN-8 package type as specified in the datasheet. Confirm the 'I' suffix indicates the Industrial temperature grade (-40°C to +85°C). Ensure the 'B' designation matches the required 16-bit word organization. Cross-reference the full part number against official Microchip documentation to confirm RoHS compliance and Pb-free finish specifications.

Memory IC Selection Notes

Select this component when a dedicated 16-bit word size is required without external configuration pins. The 93LC56BT variant provides fixed 128x16 organization, unlike the 'C' version which uses an ORG pin. Consider the TDFN-8 package for surface-mount applications requiring compact footprints. Verify that the 2.5V minimum supply voltage aligns with the system's power rails.

Memory IC Part Context

This device belongs to the 93XX56 series of 2Kbit serial EEPROMs from Microchip Technology. The series includes variants with different voltage ranges (93AA, 93LC, 93C) and organizations (A for 8-bit, B for 16-bit, C for selectable). The 93LC56BT specifically targets applications needing 2.5V operation with 16-bit words.

Memory IC Replacement Considerations

Public confirmed substitute part numbers include 93LC56AT-I/MNY and 93LC56CT-E/MNY.
