S-93C46BD0I-K8T3U

Overview

The S-93C46BD0I-K8T3U is a 1 K-bit (64 x 16) 3-wire serial EEPROM manufactured by ABLIC Inc. It operates within a voltage range of 1.8 V to 5.5 V for reading and 2.7 V to 5.5 V for writing, with a maximum clock frequency of 2.0 MHz at higher voltages. The device supports sequential read operations and includes write protection during low power supply conditions. It features an endurance of 1 million cycles per word and data retention of up to 100 years at 25°C. The component is housed in an 8-pin TMSOP package.

Feature Summary

• Supports Microwire bus communication with automatic address incrementation during sequential reads.
• Includes built-in detection to cancel write instructions when the power supply voltage drops below the threshold.
• Features a clock pulse monitoring circuit that prevents erroneous writes caused by noise or double counting.
• Provides a test pin that can be connected to ground or power supply without affecting performance.

Applications

• Consumer electronics
• Office equipment
• Communications devices

Procurement Notes

Verify the specific ordering suffix K8T3U against the manufacturer's current product name structure to confirm the package type and environmental compliance status. Ensure the design accounts for the required pull-down resistors on input pins to prevent floating states. Confirm that the application environment remains within the specified operating temperature range of -40°C to +85°C.

Selection Notes

Select this part for applications requiring low current consumption and high-speed serial access via a 3-wire interface. Consider the 1 K-bit capacity and 16-bit word organization for storing configuration data. Ensure the system voltage supports the minimum 2.7 V requirement for write operations. Verify compatibility with the Microwire protocol timing constraints before integration.

Part Context

This component belongs to the S-93C46B/56B/66B series of 3-wire serial E2PROMs from ABLIC Inc. The series offers varying memory capacities, with the S-93C46B providing 1 K-bit storage. These devices are designed for general electronic use and share common electrical characteristics and instruction sets across the family, differing primarily in memory size and address bit requirements.

Replacement Considerations

Direct substitutes include other parts within the S-93C46B series such as S-93C46BD0I-J8T1G or S-93C46BR0I-J8T1x, provided the package and environmental codes match. Cross-manufacturer replacements like the Microchip 93C46 series may require verification of pinout compatibility and timing parameters.
