Product details
Overview
CY8C4124AZI-S433T from Infineon is a programmable 32-bit Arm® Cortex®-M0+ microcontroller with 48 MHz CPU, 32 KB flash, 4 KB SRAM, integrated CAPSENSE™ capacitive sensing, and reconfigurable analog/digital blocks. It supports 1.71–5.5 V operation, deep-sleep mode at 2.5 µA, and up to 36 GPIOs in 48-pin TQFP package - deployed in human-interface touch panels, industrial control HMI, and battery-powered sensor nodes.
For engineers reviewing the CY8C4124AZI-S433T datasheet, CY8C4124AZI-S433T pinout, CY8C4124AZI-S433T application, or CY8C4124AZI-S433T equivalent, key selection criteria include capacitive SNR (>5:1), TCPWM kill-signal triggering for motor safety, SmartSense auto-tuning, SAR ADC resolution (12-bit, 1 Msps), and SCB reconfigurability across I²C/SPI/UART protocols.
Technical Context
The device integrates a fixed-function Arm® Cortex®-M0+ core with programmable analog (two opamps, 12-bit SAR ADC, two low-power comparators) and digital resources (five TCPWM blocks, three SCBs, programmable logic). Its clock system includes IMO (±2%), ILO (32 kHz), and WCO support for precise timing.
Capacitive sensing uses sigma-delta modulation with hardware-accelerated SmartSense tuning and >5:1 signal-to-noise ratio - enabling robust water-tolerant touch detection without firmware calibration. Analog and digital peripherals remain operational in Deep Sleep mode with 2.5 µA system current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0+, 48 MHz - delivers deterministic real-time control with single-cycle multiply for motor or sensor algorithms. |
| Flash / SRAM | 32 KB flash / 4 KB SRAM - sufficient for CAPSENSE™ + BLE stack + custom firmware in compact embedded applications. |
| SAR ADC | 12-bit, 1-Msps, differential/single-ended - enables high-fidelity analog sensor acquisition with channel sequencer and signal averaging. |
| CAPSENSE™ SNR | >5:1 signal-to-noise ratio - ensures reliable touch detection under moisture, noise, or ESD stress without manual tuning. |
| Deep Sleep Current | 2.5 µA - supports multi-year battery life in always-on touch interfaces or environmental monitors. |
| TCPWM Blocks | Five 16-bit Timer/Counter/PWM units - provide center-aligned PWM, quadrature decoding, and comparator-triggered kill signals for motor safety. |
| SCBs | Three serial communication blocks - each dynamically configurable as I²C, SPI, or UART, enabling flexible peripheral connectivity without pin remapping. |
Pinout & Package
Package: 48-pin TQFP (7 mm × 7 mm, 0.5 mm pitch), lead-free and RoHS-compliant. Pin functions are fully reconfigurable via PSoC™ Creator or ModusToolbox™; all GPIOs support CAPSENSE™, analog input/output, or digital logic roles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P0[0]–P0[7] | General-purpose I/O with CAPSENSE™ | Supports self- and mutual-capacitance sensing; programmable drive strength and slew rate for noise immunity. |
| P1[0]–P1[7] | Analog-capable GPIO | Connectable to SAR ADC inputs, opamp outputs, or IDAC sinks - enables mixed-signal signal chain integration. |
| P2[0]–P2[7] | Digital I/O with TCPWM/SCB routing | Directly routable to TCPWM capture/compare or SCB SCL/SDA/MOSI/MISO - eliminates external glue logic. |
| XRES | Active-low reset input | Asynchronous hardware reset with internal pull-up; compatible with pushbutton or supervisor IC assertion. |
| VDD / VSS | Power supply / ground | Single 1.71–5.5 V supply rail; decoupling required per datasheet layout guidelines for analog stability. |
| SWDIO / SWCLK | Debug interface | 2-pin Serial Wire Debug port - supports full-speed programming, real-time trace, and breakpoints without dedicated JTAG pins. |
Key Features
| Feature | Design Value |
|---|---|
| SmartSense auto-tuning | Hardware-accelerated CAPSENSE™ calibration eliminates manual firmware tuning and maintains performance across temperature/humidity drift. |
| Reconfigurable SCBs | Each of three serial blocks can be assigned I²C master/slave, SPI master/slave, or UART TX/RX at runtime - reducing BOM count and PCB footprint. |
| Deep Sleep analog retention | Opamps, comparators, and SAR ADC remain active during 2.5 µA Deep Sleep - enables wake-on-touch or wake-on-threshold events. |
| Programmable logic (PLD) | Boolean combinational logic on port inputs/outputs - implements debounce, edge detection, or state machines without CPU intervention. |
| LCD segment drive | Up to 32 segments driven directly from GPIOs - eliminates external LCD driver IC in low-cost display interfaces. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable microcontroller with capacitive sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4024LQI-S412 | Lower memory (16 KB flash / 2 KB SRAM); no TCPWM kill-signal feature; same 48-pin QFN package. | Limited to simpler touch-only applications without motor control or complex timing. | Select when cost sensitivity outweighs need for advanced PWM safety features and larger code space. |
| STM32G031F8P6 | No integrated CAPSENSE™; requires external RC network and firmware-based touch algorithm; higher active current (50 µA/MHz). | Suitable only where touch is secondary and analog sensing dominates; lacks hardware-accelerated tuning. | Choose if existing STM32 toolchain familiarity offsets CAPSENSE™ performance loss and added firmware development effort. |
Compared with CY8C4124AZI-S433T, CY8C4024LQI-S412 trades memory and safety features for lower unit cost, while STM32G031F8P6 shifts capacitive sensing burden to software and increases power overhead - making CY8C4124AZI-S433T optimal for touch-centric, safety-aware, and battery-constrained designs.

FAQ
Does CY8C4124AZI-S433T support USB connectivity?
No, CY8C4124AZI-S433T does not include a USB PHY or controller. It relies on external USB-UART bridges (e.g., CP2102) or host-side USB enumeration via its configurable SCBs operating in UART mode. USB functionality is not natively implemented in silicon.
What development tools are required to program this device?
Programming requires either Infineon's ModusToolbox™ (free, Eclipse-based IDE with PDL and CAPSENSE™ middleware) or legacy PSoC™ Creator. Both support full debug via SWD using KitProg3 or MiniProg4 programmers. No third-party toolchain licensing is needed.
Can the SAR ADC perform simultaneous sampling on multiple channels?
No, the 12-bit SAR ADC is single-channel with a hardware channel sequencer. It acquires samples sequentially with programmable delay between channels and supports signal averaging per channel - but lacks true simultaneous sampling or dual ADC cores.
Is the 48-pin TQFP package RoHS and REACH compliant?
Yes, CY8C4124AZI-S433T is certified RoHS-compliant (2011/65/EU) and REACH-conformant (SVHC-free), with lead-free matte tin finish and halogen-free molding compound - documented in Infineon's material declaration report 002-00122 Rev. *Q.
