Product details
Overview
CY8C4124PVS-442Z from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex™-M0 programmable system-on-chip (PSoC® 4100 family) integrating MCU, reconfigurable analog/digital blocks, 12-bit 806 ksps SAR ADC, two opamps with comparator mode, and two SCBs supporting I²C/SPI/UART. It operates from 1.71 V to 5.5 V and supports –40 °C to +105 °C industrial temperature range. Used in capacitive touch HMI, motor control feedback, and low-power sensor nodes.
For engineers reviewing the CY8C4124PVS-442Z datasheet, CY8C4124PVS-442Z pinout, CY8C4124PVS-442Z application, or CY8C4124PVS-442Z equivalent, key selection criteria include its 24-MHz CPU speed, 32 kB flash / 4 kB SRAM memory map, Deep Sleep current of 20 nA, CapSense Sigma-Delta (CSD) support with >5:1 SNR, and dual SCB flexibility for mixed-protocol communication interfaces.
Technical Context
The device implements a single-layer AHB-Lite interconnect between CPU, memory, and peripherals, enabling deterministic access timing and low-latency peripheral response. Its programmable analog subsystem includes two CTBm (Capacitive Touch Block) opamps configurable as buffers, comparators, or transimpedance amplifiers, each with dedicated ADC input buffering capability.
Digital logic is implemented via DSI (Digital System Interconnect), allowing runtime reconfiguration of TCPWM outputs, SCB protocols, and GPIO routing without firmware reload. The SWD debug interface provides full on-chip debugging with four address breakpoints and two data watchpoints, enabled by default and disableable only in firmware.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4247LQI-BL483 | Same PSoC 4200 family; adds Bluetooth LE radio and 64 kB flash, but no LCD drive support. | Targeted at wireless-connected devices where RF integration reduces external component count. | Select when BLE connectivity is mandatory and LCD driving is unnecessary. |
| STM32F072RBT6 | Arm Cortex-M0, 48 MHz, 128 kB flash, 16 kB SRAM, but fixed-function peripherals only - no reconfigurable analog/digital blocks. | Suitable for cost-sensitive, high-volume applications with stable peripheral requirements and no field reconfiguration needs. | Select when deterministic peripheral mapping and larger memory outweigh programmability benefits. |
Compared with CY8C4124PVS-442Z, CY8C4247LQI-BL483 trades LCD capability for integrated BLE and higher memory, while STM32F072RBT6 offers greater raw memory and clock speed but lacks hardware reconfigurability - making it less adaptable to evolving analog signal chain or protocol requirements.

FAQ
What debug interface does CY8C4124PVS-442Z support?
CY8C4124PVS-442Z uses the Arm Serial Wire Debug (SWD) interface with two dedicated pins (SWDIO and SWCLK). It supports full programming, real-time debugging, four address breakpoints, and two data watchpoints. Debug is enabled by default and can be disabled only through firmware - re-enabling requires full flash erase if disabled.
Does CY8C4124PVS-442Z support capacitive touch sensing out of the box?
Yes - it integrates Cypress CapSense Sigma-Delta (CSD) hardware with >5:1 SNR and built-in water tolerance. The device includes SmartSense™ auto-tuning firmware libraries and supports up to 36 self- or mutual-capacitance sensors using any GPIO pin without external components.
Can CY8C4124PVS-442Z operate from a 1.8-V supply?
Yes - its operating voltage range is 1.71 V to 5.5 V. At 1.8 V, the maximum CPU frequency is reduced to 20 MHz per electrical specifications, and analog performance (e.g., ADC ENOB, opamp GBW) meets datasheet limits under those conditions.
Is there hardware support for LCD segment driving?
Yes - CY8C4124PVS-442Z supports static and multiplexed LCD driving on all GPIO pins (up to 36 segments and commons), with dedicated memory bits per pin retained during Deep Sleep mode. It supports 4-bit per-pin memory and direct mapping to TCPWM or SCB outputs for timing-critical displays.
