93LC86C-E/MS

Memory IC Overview

The Microchip Technology 93LC86C-E/MS is a 16K-bit low-voltage serial EEPROM utilizing Microwire-compatible 3-wire serial I/O. It features an automotive temperature range of -40°C to +125°C and operates within a supply voltage range of 2.5V to 5.5V. The device supports a maximum clock frequency of 3 MHz at higher voltages, with sequential read capabilities and self-timed erase/write cycles. Memory organization is selectable between 2K x 8 or 1K x 16 via the ORG pin, and it includes a Program Enable (PE) pin for hardware write protection.

Memory IC Feature Summary

• Configurable memory word size selection via external logic levels on the ORG pin
• Hardware write protection capability through the dedicated Program Enable pin
• Integrated power-on/off data protection circuitry to prevent corruption during voltage transitions
• Ready/Busy status signaling available on the Data Output pin during programming operations

Memory IC Applications

• Automotive electronic control units requiring nonvolatile storage
• Industrial systems needing robust data retention under extreme temperatures
• Low-power embedded devices utilizing serial communication interfaces
• Configuration storage in microcontroller-based architectures

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm that the 'E' designation aligns with your system's operational thermal environment specifications. Ensure compatibility with the Microwire protocol timing requirements before finalizing procurement decisions.
