AT93C86A-10SU-1.8

Memory IC Overview

The AT93C86A-10SU-1.8 is a 16-Kbit (2,048 x 8 or 1,024 x 16) three-wire serial EEPROM manufactured by Microchip Technology. It operates within a supply voltage range of 1.8V to 5.5V and supports clock frequencies up to 2 MHz at 5V. The device features an industrial temperature range from -40°C to +85°C and utilizes an 8-lead SOIC package.

Memory IC Feature Summary

• Supports user-selectable internal memory organization as either 2,048 x 8-bit or 1,024 x 16-bit via the ORG pin.
• Includes Schmitt trigger filtered inputs for noise suppression on the three-wire serial interface.
• Features self-timed erase/write cycles with automatic ready/busy status output capability.

Memory IC Applications

• Industrial applications requiring low-power and low-voltage operations
• Commercial applications utilizing three-wire serial communication
• Systems needing non-volatile data storage with configurable word sizes

Memory IC Procurement Notes

Verify that the specific suffix '1.8' corresponds to the 1.8V minimum operating voltage grade in the official datasheet. Confirm the 'S' indicates the 8-lead SOIC package type. Ensure the 'U' denotes the unbuffered version if applicable to your design requirements. Cross-reference the full part number against the manufacturer's current product identification system to avoid ordering errors.

Memory IC Selection Notes

Select this component when a 16-Kbit capacity is required with a three-wire serial interface. Choose the 1.8V grade variant if the system operates at lower supply voltages. The ORG pin allows flexibility in memory organization without changing hardware. Ensure the application environment stays within the specified industrial temperature range for reliable operation.

Memory IC Part Context

This device belongs to the AT93C86A family of Microwire-compatible serial EEPROMs. It shares functional similarities with other 16-Kbit devices in the series but differs in package options and voltage grades. The 'SU' designation specifically identifies the surface-mount SOIC package variant within the broader product line.

Memory IC Replacement Considerations

The 93AA86C-I/SN is listed as a substitute part number. Verify compatibility regarding package dimensions, voltage ranges, and timing characteristics before implementation.
