AT93C66-10TI-1.8

Memory IC Overview

The AT93C66-10TI-1.8 is a 4Kbit (4096-bit) serial electrically erasable programmable read-only memory (EEPROM) manufactured by Microchip Technology. It operates within a supply voltage range of 1.8V to 5.5V and supports a clock frequency up to 2 MHz at 5V. The device features an industrial temperature range of -40°C to +85°C and utilizes an 8-lead Thin Shrink Small Outline Package (TSSOP). Memory organization is user-selectable between 512 x 8 or 256 x 16 configurations via the ORG pin.

Memory IC Feature Summary

• Supports three-wire serial interface with self-timed write cycles
• Provides high reliability with one million write cycle endurance
• Features user-selectable internal memory organization for flexible data storage

Memory IC Applications

• Industrial applications requiring low-power operations
• Commercial systems utilizing low-voltage logic
• Data storage in embedded controllers

Memory IC Procurement Notes

Verify the specific ordering suffix matches the required package type, as the TI designation indicates an 8-lead TSSOP package. Confirm the voltage option corresponds to the 1.8V specification. Ensure the component meets the necessary environmental standards for your deployment. Cross-reference the manufacturer's current datasheet revision to validate all electrical parameters before finalizing procurement specifications.

Memory IC Selection Notes

Select this component when a 4Kbit EEPROM capacity is required with a three-wire serial interface. The 1.8V operating range makes it suitable for low-voltage systems. Consider the TSSOP package if space-constrained surface-mount assembly is needed. Verify that the host processor can support the synchronous timing requirements for the SK, DI, and DO pins during read and write operations.

Memory IC Part Context

This part belongs to the AT93C46/56/66 family of serial EEPROMs. The '66' variant specifically provides 4096 bits of storage. While originally developed by Atmel Corporation, the product line is now managed by Microchip Technology. This generation serves as a predecessor to newer A-series devices, offering standard performance for established designs.

Memory IC Replacement Considerations

The datasheet notes that this device is not recommended for new designs and suggests referring to the AT93C66A. Verify compatibility with the AT93C66A regarding pinout and instruction set before substitution.
