The CY8C4126AZI-M443 from Infineon is a versatile ARM Cortex-M0 microcontroller designed for low-power and touch-sensing applications. It operates from 1.71V to 5.5V, runs at 24MHz, and features 64KB flash and 8KB SRAM. Integrated CapSense, LCD driver, and multiple serial interfaces make it ideal for HMI, industrial, and consumer products. The 48-LQFP package and extended temperature range support demanding environments.
- Integrated CapSense: Eliminates external touch ICs, reducing cost and PCB area while improving design flexibility.
- Wide Voltage Range (1.71V-5.5V): Supports both 3.3V and 5V systems, simplifying power supply design and enabling direct battery operation.
- Low Power Consumption: Multiple sleep modes and fast wake-up extend battery life in portable devices.
- Rich Analog Peripherals: Includes ADC, comparators, and current DACs for precise sensor interfacing.
- Robust Protection: Brown-out detect, low-voltage detect, and watchdog timer enhance system reliability.
Industrial Human-Machine Interface (HMI)
With integrated CapSense, the CY8C4126AZI-M443 can implement capacitive touch buttons, sliders, and proximity sensors without external components, reducing BOM cost and improving reliability in industrial panels.
Portable Medical Devices
The wide 1.71V to 5.5V supply range and low-power modes enable battery-operated glucose meters, pulse oximeters, and thermometers. The LCD driver simplifies segmented display integration.
Smart Home Controllers
Use the PWM and analog peripherals to control lighting, motorized blinds, and environmental sensors. The 24MHz Cortex-M0 provides enough processing for real-time control loops.
