AT93C46C-10PI

Memory IC Overview

The AT93C46C-10PI is a 1-kbit (128 x 8 or 64 x 16) Microwire serial EEPROM manufactured by Microchip Technology. It operates within a supply voltage range of 2.5 V to 5.5 V and supports clock frequencies up to 2 MHz. The device features a 200 ns access time and is housed in an 8-pin PDIP package for through-hole mounting. It functions across an industrial temperature range of -40°C to +85°C and offers a data retention period of 200 years.

Memory IC Feature Summary

• Supports Microwire 3-wire serial interface with configurable 8-bit or 16-bit word organization
• Provides high-speed serial read and write operations with low power consumption
• Ensures long-term non-volatile data storage with extended retention capabilities

Memory IC Applications

• Industrial control systems requiring parameter storage
• Consumer electronics for configuration data retention
• Automotive modules needing reliable non-volatile memory

Memory IC Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +85°C) and 'P' indicates the PDIP package. Confirm the 'C' variant specifications against the official datasheet, as some variants may differ in voltage or speed. Ensure compatibility with existing Microwire protocol implementations before procurement.

Memory IC Selection Notes

Select this component when a robust, low-pin-count serial EEPROM is required for industrial environments. The 1-kbit capacity suits applications storing calibration data or user settings. The PDIP package facilitates prototyping and through-hole assembly. Verify that the system's microcontroller supports the Microwire interface timing requirements.

Memory IC Part Context

This part belongs to the AT93C46 series of Microwire-compatible serial EEPROMs. It shares functional similarities with the 93C46 family but includes specific Microchip designations. The series is designed for cost-effective, small-capacity non-volatile memory needs in embedded systems where space and pin count are constrained.

Memory IC Replacement Considerations

Direct replacements include other AT93C46 variants with compatible packages and temperature ranges. Cross-reference with 93LC46C-I/P for similar electrical characteristics. Ensure substitute parts match the Microwire interface protocol and voltage levels.
