93C46BT-E/MS

Memory IC Overview

The Microchip Technology 93C46BT-E/MS is a 1-kbit Microwire serial EEPROM housed in an 8-lead MSOP package. It features a 64 x 16 memory organization and supports a maximum clock frequency of 3 MHz. The device operates within a supply voltage range of 4.5 V to 5.5 V and is rated for an extended industrial temperature range from -40°C to +125°C. Key electrical specifications include a 250 ns access time, 1 mA maximum active read current, and 2 mA operating supply current.

Memory IC Feature Summary

• Supports high-speed Microwire serial interface with up to 3 MHz clock capability
• Provides hardware or software write protection mechanisms
• Features self-timed erase and write cycles for autonomous operation

Memory IC Applications

• Industrial control systems requiring non-volatile data storage
• Automotive electronics operating in extended temperature environments
• Smart metering applications needing secure parameter retention

Memory IC Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature grade (-40°C to +125°C) and 'MS' denotes the MSOP-8 package. Confirm that the 'T' suffix specifies tape-and-reel packaging suitable for automated surface-mount assembly. Ensure compatibility with 4.5V to 5.5V logic levels before integration into the target circuit design.

Memory IC Selection Notes

Select this component when a 64-word by 16-bit structure is required rather than the 128x8 configuration found in other series variants. Choose the MSOP-8 package for space-constrained surface-mount designs. The extended temperature rating makes it suitable for harsh automotive or industrial environments where standard commercial grades would fail.

Memory IC Part Context

This part belongs to the 93C46A/B/C family of low-power CMOS serial EEPROMs manufactured by Microchip Technology. The 'B' designation typically indicates a fixed 64x16 organization, while the 'C' variant allows selection via an ORG pin. This specific model represents the tape-and-reel version of the commercial-grade device adapted for extended industrial temperatures.
