93C86CT-I/ST

Memory IC Overview

The Microchip Technology 93C86CT-I/ST is a 16-kbit Microwire-compatible serial EEPROM housed in an 8-pin TSSOP package. It features a storage organization of 1024 words by 16 bits or 2048 words by 8 bits, selectable via the ORG pin. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports clock frequencies up to 3 MHz. It offers a data retention period of 200 years and endurance of one million write/erase cycles. The industrial temperature grade covers operation from -40°C to +85°C.

Memory IC Feature Summary

• Microwire-compatible three-wire serial interface for efficient communication.
• Self-timed erase and write cycles with automatic erase-all functionality.
• Configurable memory organization allowing selection between 8-bit and 16-bit word sizes.

Memory IC Applications

• Industrial control systems requiring non-volatile parameter storage.
• Consumer electronics needing compact configuration memory.
• Automotive applications utilizing industrial-grade components.

Memory IC Procurement Notes

Verify the specific suffix 'T' against official datasheets to confirm tape-and-reel packaging status, as standard listings may indicate tube packaging. Ensure the operating voltage matches the 4.5 V to 5.5 V requirement. Confirm the industrial temperature range aligns with system thermal constraints before finalizing procurement.

Memory IC Selection Notes

Select this component when a Microwire interface is required instead of SPI. The 93C86CT variant provides surface-mount convenience in a TSSOP-8 package. Consider the 93LC86 series if lower voltage operation is necessary, or the 93AA86 series for wider voltage compatibility.

Memory IC Part Context

This part belongs to the 93C86 family of 16-kbit serial EEPROMs from Microchip Technology. The family includes variants with different packages such as PDIP, SOIC, and MSOP, and different voltage ranges like the 93LC86 and 93AA86 series. The 'I' designation indicates industrial temperature rating.

Memory IC Replacement Considerations

Compatible substitutes include other members of the 93C86 family, such as the 93C86C-I/SN (SOIC) or 93C86A-I/P (PDIP), provided the memory organization and voltage requirements are met. Verify pinout compatibility and interface protocol support.
