The CY8C4124LQA-S433T from Infineon is a PSoC 4 microcontroller featuring an ARM Cortex-M0+ core at 24 MHz. It provides 16KB of flash and 4KB of SRAM, along with integrated CapSense touch sensing and an LCD driver. With a supply range of 1.71V to 5.5V and a 40-UFQFN package, this device is designed for human-machine interface applications requiring flexible analog and digital integration.
- Integrated CapSense: Eliminates external touch controllers, reducing cost and simplifying PCB design for user interfaces.
- Wide Supply Range: Operates from 1.71V to 5.5V, supporting both 3.3V and 5V systems without level shifters.
- Built-in LCD Driver: Enables direct segmented display control, saving additional driver ICs.
- Compact 40-UFQFN: Small footprint with exposed pad for thermal management in dense designs.
- Low-Power Modes: Supports battery-operated applications with efficient sleep and wake-up cycles.
Touch-Sensitive Consumer Electronics
The integrated CapSense block allows designers to implement buttons, sliders, and proximity sensors on appliances, wearables, and remote controls without dedicated touch ICs.
Smart Home Control Panels
Combining LCD output, CapSense input, and 5.5V operation, it suits wall-mounted keypads and thermostat interfaces with backlit displays.
Industrial Human-Machine Interfaces (HMI)
The 24MHz Cortex-M0+ and PWM capabilities support simple HMI panels with LED dimming and touch feedback in machinery.
Battery-Powered IoT Sensors
With 1.71V minimum operation and low-power modes, it enables long-life wireless sensor nodes that wake periodically to transmit data.
Automotive Interior Controls
Operating from -40°C to 85°C, it handles dashboard touch buttons and ambient lighting control in vehicles.
Medical Handheld Instruments
The CapSense interface and LCD driver facilitate hygienic, easy-to-clean touch surfaces on glucose meters and drug delivery devices.
