Procurement Notes

Verify the manufacturer designation carefully, as some listings associate this part number with Littelfuse, Inc., while others cite Zilog. Confirm the specific datasheet version and pinout compatibility before integration. Ensure the supplier provides official documentation supporting the 1.8V to 5.5V operating range and the TSSOP-28 package dimensions. Cross-reference the memory size and interface specifications against your system requirements to avoid mismatches.

Selection Notes

Select this component when both UART and I2C connectivity are required in a space-constrained design. The wide voltage tolerance allows flexibility in power supply design. Consider the thermal performance within the specified temperature range for harsh environments. Evaluate the 57.6 kb/s data rate limit against application throughput needs. The low current draw makes it suitable for battery-operated or energy-efficient systems.

Part Context

This microcontroller belongs to the ZDU series of communications devices. It serves as a bridge between digital systems and serial protocols. The TSSOP-28 form factor enables efficient PCB layout. It complements other Zilog embedded solutions by providing dedicated interface handling without burdening the main processor.
