S-93C76ADFJ-TB-U

Overview

The S-93C76ADFJ-TB-U is a high-speed, low-current consumption 3-wire serial EEPROM with an 8 K-bit capacity organized as 512 words by 16 bits. It operates on a Microwire bus interface and supports sequential reading with automatic address incrementing in 16-bit blocks. The device functions within a read voltage range of 1.8 V to 5.5 V and a write voltage range of 2.7 V to 5.5 V. Maximum operating frequency reaches 2.0 MHz at supply voltages between 4.5 V and 5.5 V. The component includes a write protect function triggered during low power supply conditions.

Feature Summary

• Supports sequential read operations with automatic address incrementing for efficient data retrieval.
• Includes built-in detection circuitry to disable writing during low power supply voltage events.
• Features a three-wire serial communication interface compatible with the Microwire bus protocol.

Applications

• Consumer electronics
• Office equipment
• Communications devices

Procurement Notes

Verify the specific package type against the ordering suffix, as the datasheet lists SOP, TSSOP, and TMSOP options. Confirm that the application environment remains within the specified temperature range of -40°C to +85°C. Ensure the design accounts for the required pull-down resistors on input pins to prevent floating states. Check for any specific end-of-life or NRND status updates from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a non-volatile memory solution requires a simple three-wire interface and low current consumption. It is suitable for applications needing moderate storage density with fast read speeds. Designers must ensure the system voltage meets the minimum threshold for write operations if programming is required. Consider the physical package constraints and the need for external pull-down resistors on control lines during selection.

Part Context

This part belongs to the S-93C76A series of 3-wire serial EEPROMs manufactured by ABLIC Inc. The series is designed for general electronic devices requiring reliable data storage with minimal pin count. The specific model indicates a particular package variant within the broader family of 8 K-bit memory solutions offered by the manufacturer.

Replacement Considerations

Consult official ABLIC documentation for direct substitutes. Verify compatibility regarding the Microwire interface timing and voltage levels when considering alternative EEPROMs. Ensure any replacement maintains the same memory organization and package dimensions if board space is constrained.
