The Infineon CY8C4125AXI-M445 is a PSoC 4 MCU built around a 24MHz ARM Cortex-M0 core. It offers 32KB flash and 4KB SRAM, with a wide 1.71V to 5.5V supply range. Integrated CapSense, LCD drive, and multiple protection circuits (Brown-out, LVD, POR, WDT) make it a versatile choice for human-machine interfaces and industrial sensing. The 64-LQFP package provides ample I/O for complex designs.
- Integrated CapSense: Eliminates external touch controllers, reducing BOM cost and board space.
- Wide Voltage Range (1.71V-5.5V): Simplifies power supply design, allowing direct battery or 5V rail operation.
- Robust Protection: Built-in Brown-out Reset, LVD, and WDT enhance system reliability in noisy environments.
- Low-Power Cortex-M0: Efficient 24MHz core balances performance and energy consumption for battery devices.
