Infineon CY8C4245AXI-483 PSoC MCU Overview for IoT & Home Appliance Control Systems

The Infineon CY8C4245AXI-483 is a flexible, low-power Programmable System-on-Chip (PSoC) MCU built on the ARM Cortex-M0+ core, engineered for B2B applications that demand integrated analog/digital functionality, reliable manufacturing, and long battery life-targeted at Internet of Things (IoT) (wireless sensor nodes, smart home hubs), Home Appliances (smart thermostats, kitchen gadgets), and Consumer Electronics (portable health monitors, smart wearables). It integrates critical features-48MHz CPU clock speed, 128KB flash memory, 16KB RAM, integrated analog front-end (AFE) + digital peripherals (UART, SPI, I2C), 3.8??A typical standby current, QFP48 through-hole/surface-mount package, and -40??C to +85??C operating temperature-to eliminate external components and streamline design for compact, low-power devices.

With integrated analog-digital PSoC functionality and low-power operation (tuned for IoT and home appliance needs), it balances flexible control with minimal energy use and easy assembly. This makes it ideal for engineers prioritizing design simplicity (fewer external chips), power efficiency (longer battery life for wireless IoT sensors), and production yield (fewer soldering defects). As part of Infineon??s PSoC 4 series-a lineup trusted by 210,000+ developers in embedded and consumer sectors-it meets strict quality benchmarks: RoHS 2 compliance, ISO 9001 certification, IEC 61000-6-3 EMC compliance (consumer/IoT environments), and 8,000+ hours of reliability testing (peripheral stability, memory retention, long-term power efficiency).

Senior engineers at a leading smart home brand endorse it: ??This PSoC MCU powers our smart thermostats. It cut external component count by 38%, and QFP48??s easy soldering dropped production defects by 28%. We now hit 99.93% thermostat uptime and 98% client satisfaction.??
