Memory IC datasheet and documents for 93LC46C-I/ST

93LC46C-I/ST

Memory IC Overview

The Microchip Technology 93LC46C-I/ST is a 1Kbit low-voltage serial Electrically Erasable PROM (EEPROM) housed in an 8-lead TSSOP package. It utilizes Microwire-compatible 3-wire serial I/O and supports word-selectable memory organization via the ORG pin, allowing configuration for either 128 x 8-bit or 64 x 16-bit data structures. The device operates within a supply voltage range of 2.5V to 5.5V and features industrial temperature ratings from -40°C to +85°C.

Memory IC Feature Summary

Configurable memory architecture selectable between 8-bit and 16-bit word sizes using the external ORG pin
Integrated power-on and power-off protection circuitry to prevent data corruption during voltage transitions
Self-timed erase and write cycles with automatic Erase All functionality preceding Write All operations

Memory IC Applications

Low-power nonvolatile storage for microcontroller system parameters
Configuration data retention in embedded control circuits
Calibration value storage in industrial instrumentation

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design specifications align with the documented electrical characteristics for the intended operating environment.

Memory IC Selection Notes

Select this component when flexible memory width is required without changing hardware revisions. The ORG pin allows adaptation to different bus widths. Verify that the 2.5V minimum supply voltage meets the system requirements, as lower voltage variants exist within the broader product family.

Memory IC Part Context

This part belongs to the 93XX46 series of Microwire compatible EEPROMs. The 'C' designation indicates support for both 8-bit and 16-bit organizations, distinguishing it from dedicated 'A' (8-bit only) and 'B' (16-bit only) devices. The 'I' suffix specifies the industrial temperature range suitable for general commercial applications.
