The S3F84I9XZZ-QZ89 is a QFP-44 RoHS-compliant Other Processors and Microcontrollers (MCUs) manufactured by IXYS. This MCU is designed to incorporate clock and timer peripherals, data memory, and instruction set architecture into a single chip to enable various control tasks on a simple system level. It offers features such as 8-bit built-in program memory, a low-voltage reset circuit, and a watchdog timer. Additionally, it also provides a wide range of interrupt sources, 2048 bytes RAM and up to 512 bytes of data memory. With its low-power operation and programmability, this device is suitable for handling data segmentation, data routing, software updates, and other control functions for industrial IoT applications.
