S-34TS04L0B-A8T5U5

Overview

The S-34TS04L0B-A8T5U5 is a 2-wire serial EEPROM with an integrated temperature sensor. It features 4 K-bit capacity organized as two pages of 256 words by 8 bits. Operating voltage ranges from 1.7 V to 3.6 V, supporting I2C bus frequencies up to 1.0 MHz. The device includes software write protection for four 128-byte blocks and SMBus timeout functionality. Temperature accuracy is ±0.5°C typical between +75°C and +95°C. Endurance is rated at 10^6 cycles per word, with data retention of 100 years.

Feature Summary

• Integrated digital temperature sensor with selectable hysteresis and EVENT pin output
• Software-based individual block write protection mechanism
• SMBus timeout function for communication stability
• Low power consumption with shutdown modes

Applications

• Solid State Drives (SSDs)
• Consumer electronics
• Office equipment
• Communication devices

Procurement Notes

Verify the specific ordering suffix A8T5U5 corresponds to the DFN-8(2030)B package and tape reel packing configuration. Confirm that the application environment falls within general electronic device usage; contact the manufacturer for automotive or medical equipment integration requirements before procurement.

Selection Notes

Select this component when both non-volatile storage and ambient temperature monitoring are required on a single I2C bus. Ensure the system supports the 1.7 V to 3.6 V supply range and utilizes open-drain outputs for SDA/SCL lines. Verify that the 4 K-bit capacity meets the memory requirements and that the DFN-8 package fits the PCB layout constraints.

Part Context

This part belongs to the S-34TS04L series of 2-wire serial EEPROMs manufactured by ABLIC Inc. The series combines standard E2PROM functions with a dedicated temperature sensing block. The 'B' suffix indicates an operating temperature range of -20°C to +125°C, while 'A8T5' specifies the DFN-8 package and tape packing.

Replacement Considerations

Direct replacements must match the 4 K-bit capacity, I2C interface, and DFN-8 package. Verify compatibility with the specific DTIC codes used for EEPROM and temperature sensor access. Check if alternative parts support the same SMBus timeout feature and software write protection architecture.
