93AA86CT-I/MC

Memory IC Overview

The Microchip Technology 93AA86CT-I/MC is a 16K bit low-voltage serial EEPROM utilizing Microwire-compatible 3-Wire Serial I/O. It features an 8-lead 2x3 DFN package and supports a supply voltage range of 1.8V to 5.5V. The device offers industrial temperature operation from -40°C to +85°C. Memory organization is selectable between 2048 x 8-bit and 1024 x 16-bit via the ORG pin. Key electrical specifications include a maximum clock frequency of 3 MHz, 1,000,000 erase/write cycles endurance, and data retention exceeding 200 years.

Memory IC Feature Summary

• Configurable memory word size selection through external logic levels on the ORG pin
• Integrated power-on and power-off data protection circuitry for voltage integrity
• Self-timed erase and write cycles with automatic erase-before-write functionality
• Hardware write-protection capability via the dedicated Program Enable (PE) pin

Memory IC Applications

• Low-power nonvolatile memory storage in battery-operated devices
• Industrial control systems requiring reliable data retention
• Embedded applications needing configuration parameter storage
• Microwave compatible serial interface memory modules

Memory IC Procurement Notes

Verify that the specific ordering suffix CT indicates cut tape packaging rather than reel quantities when sourcing samples or small batches. Confirm the MC suffix corresponds to the 8-lead 2x3 DFN package format required by your PCB layout. Ensure the I designation matches your operational temperature requirements of -40°C to +85°C. Cross-reference the datasheet revision to confirm compatibility with your system's voltage levels.

Memory IC Selection Notes

Select this component when a Microwire interface is preferred over SPI or I2C protocols. Choose the 93AA86CT variant specifically if the design requires the compact 2x3 DFN footprint. The 'C' version is necessary only if dynamic word-size selection or hardware write-protection via the PE pin is required. Verify that the 1.8V minimum operating voltage aligns with your system's power rail capabilities.
