93LC46A-E/SN

Memory IC Overview

The Microchip Technology 93LC46A-E/SN is a 1Kbit low-voltage serial Electrically Erasable PROM (EEPROM) utilizing advanced CMOS technology. It features an 8-bit word 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 provides data retention exceeding 200 years with 1,000,000 erase/write cycles endurance. Designed for industrial applications, it functions reliably across a temperature range of -40°C to +125°C and is housed in an 8-lead SOIC package.

Memory IC Feature Summary

• Low-power CMOS construction suitable for nonvolatile memory applications
• Self-timed erase and write cycles with automatic erase before write all operations
• Power-on/off data protection circuitry prevents accidental programming during power fluctuations
• Industry standard 3-wire serial I/O interface with Ready/Busy status signal

Memory IC Applications

• Industrial control systems requiring reliable parameter storage
• Automotive electronics operating under extended temperature conditions
• Embedded devices needing compact serial EEPROM solutions

Memory IC Procurement Notes

Verify the specific suffix 'E' indicates automotive grade qualification (-40°C to +125°C) and 'SN' denotes the 8-lead SOIC package. Confirm RoHS compliance and lead-free matte tin finish requirements against current datasheet specifications. Ensure sourcing channels provide valid traceability codes matching the manufacturer's marking legend.

Memory IC Selection Notes

Select this component when fixed 8-bit word size is required without external configuration pins. Compare against 93LC46C variants if dynamic word size selection via the ORG pin is necessary. Consider the 93LC46B variant if 16-bit word organization is preferred for the application architecture.

Memory IC Part Context

This part belongs to the 93XX46A/B/C series of 1Kbit Microwire compatible serial EEPROMs. The 'A' designation specifies dedicated 8-bit communication capability, distinguishing it from 'B' (16-bit) and 'C' (selectable) versions. The series utilizes low-voltage CMOS technology for efficient operation in space-constrained designs.

Memory IC Replacement Considerations

Direct functional substitutes include other 93LC46A variants with different temperature grades or packages, such as 93LC46A-I/SN for industrial temperature ranges.
