S-93C46CD0H-T8T2U3

Memory IC Overview

The S-93C46CD0H-T8T2U3 is a 1 K-bit (64-word × 16-bit) 3-wire serial E2PROM from the S-93C46C/56C/66C/76C/86C H Series. It operates within a voltage range of 1.6 V to 5.5 V for reading and 1.8 V to 5.5 V for writing, with a maximum clock frequency of 2.0 MHz. The device supports sequential read operations and features an 8-pin TSSOP package. It is qualified for automotive applications with an operating temperature range of −40°C to +105°C.

Memory IC Feature Summary

• Supports sequential read operations with automatic address incrementation in 16-bit blocks.
• Includes a write protect function that activates during low power supply voltage conditions.
• Features a built-in clock pulse monitoring circuit to prevent erroneous writes caused by noise or double counting.

Memory IC Applications

• Automotive electronic control units
• Medical equipment data storage
• Industrial systems requiring high reliability

Memory IC Procurement Notes

Verify AEC-Q100 qualification details directly with sales representatives as specifications may vary. Confirm the specific tape packing requirements for the T8T2 suffix before ordering. Ensure the application environment stays within the specified temperature and voltage limits to maintain data retention guarantees.

Memory IC Selection Notes

Select this component for designs requiring 1 K-bit non-volatile memory with Microwire interface compatibility. The TSSOP-8 package suits space-constrained PCB layouts. Consider the 105°C operation grade if the system exceeds standard commercial temperature ranges. Verify write enable/disable logic integration with the host controller.

Memory IC Part Context

This part belongs to the S-93C46C/56C/66C/76C/86C H Series, which offers capacities from 1 K-bit to 16 K-bit. The 'H' designation indicates support for operation up to 105°C, suitable for automotive environments. The series shares common instruction sets and electrical characteristics across different memory densities.

Memory IC FAQ

How does the device handle write operations during low voltage?

A built-in detection circuit automatically cancels write instructions and sets the write disable status when the supply voltage drops below approximately 1.2 V.

What is the initial delivery state of the memory addresses?

All memory addresses are initialized to FFFFh upon delivery.
