Product details
Overview
CY8C4124PVI-432T 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 SAR ADC, two opamps, and two SCBs supporting I²C/SPI/UART. It operates from 1.71 V to 5.5 V, delivers 24 MHz CPU performance with single-cycle multiply, and includes 32 kB flash and 4 kB SRAM. Used in capacitive touch HMI, industrial sensor nodes, and low-power embedded control.
For engineers reviewing the CY8C4124PVI-432T datasheet, CY8C4124PVI-432T pinout, CY8C4124PVI-432T application, or CY8C4124PVI-432T equivalent, key selection criteria include its 48-pin TQFP package, 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 tightly coupled AHB-Lite bus architecture with separate memory-mapped peripherals (TCPWM, SCB, SAR ADC, CTBm) and a programmable digital system interconnect (DSI) enabling dynamic routing between analog and digital resources. Its clock system integrates IMO (24 MHz ±2%) and ILO (32.768 kHz), with automatic glitch-free switching and dedicated sleep-mode clock gating.
Capacitive sensing is handled by dedicated hardware (CSD block) with SmartSense™ auto-tuning, while analog signal conditioning uses two rail-to-rail opamps configurable as buffers, comparators, or ADC input drivers - all operating down to Deep Sleep mode with wakeup capability via GPIO or comparator event.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0, 24 MHz max, single-cycle 32-bit multiply - enables deterministic real-time control and Thumb-2 binary compatibility with higher Cortex-M families. |
| Flash / SRAM | 32 kB flash with Read Accelerator, 4 kB SRAM - supports firmware storage with zero-wait-state execution at full speed and data retention during Hibernate. |
| ADC | 12-bit SAR, 806 ksps, differential/single-ended, channel sequencer with signal averaging - enables high-resolution sensor acquisition with noise reduction in resource-constrained systems. |
| Analog Peripherals | 2 opamps (reconfigurable buffer/comparator/ADC driver), 2 low-power comparators, 2 IDACs - provides on-chip signal conditioning and capacitive sensing excitation without external components. |
| Communication | 2 SCBs, each configurable as I²C/SPI/UART - allows concurrent use of different protocols (e.g., I²C sensor interface + UART debug port) with runtime reconfiguration. |
| Power Modes | Stop (20 nA), Deep Sleep (1.3 µA typical), Hibernate (200 nA) - supports battery-powered operation with fast wake-up (< 5 µs from Deep Sleep) and pin-triggered resume. |
| Operating Range | 1.71 V to 5.5 V, –40 °C to +105 °C - ensures robust operation across industrial power rails and extended temperature environments. |
Pinout & Package
Package: 48-pin TQFP (7 mm × 7 mm, 0.5 mm pitch), RoHS-compliant, lead-free, surface-mount.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Power supply and ground | Dual VDD pins (Pins 1, 48) and four VSS pins (Pins 2, 24, 25, 47) ensure stable core and I/O rail decoupling in mixed-signal layouts. |
| P0[0]–P0[7], P1[0]–P1[7], P2[0]–P2[7], P3[0]–P3[7], P4[0]–P4[3] | Programmable GPIO | All 36 pins support CapSense, analog input/output, LCD segment/common, or digital logic with configurable drive strength/slew rate. |
| SWDCLK, SWDIO | Debug interface | Two-pin Serial Wire Debug (SWD) enables full on-chip programming, breakpoint, and watchpoint debugging without JTAG overhead. |
| XRES | External reset | Active-low asynchronous reset input with internal pull-up; overrides all power modes and initiates cold boot sequence. |
| XTAL_IN / XTAL_OUT | External crystal interface | Optional 1–33 MHz crystal connection for precision timing; bypassed when using internal IMO/ILO oscillators. |
Key Features
| Feature | Design Value |
|---|---|
| CapSense CSD Engine | Hardware-accelerated sigma-delta modulation with >5:1 SNR and water-tolerant scanning - eliminates firmware-based polling and enables reliable touch buttons/sliders in humid environments. |
| SmartSense™ Auto-Tuning | Firmware-transparent calibration of CapSense parameters (IDAC, resolution, scan time) - reduces design iteration time and compensates for PCB parasitics and environmental drift. |
| Reconfigurable SCBs | Two independent serial communication blocks supporting I²C master/slave, SPI master/slave, or UART TX/RX simultaneously - avoids peripheral conflicts in multi-interface designs. |
| Deep Sleep with Analog Wakeup | Comparator and opamp remain active in Deep Sleep; generate interrupt on threshold crossing - enables ultra-low-power sensor monitoring without CPU intervention. |
| Flash Security Modes | Open/Protected/Kill modes with row-level read/write protection - prevents unauthorized firmware extraction or partial erase attacks in field-deployed devices. |
Applications
| Industrial Sensor Node | Capacitive Touch HMI |
|---|---|

Use Value: Integrated IDACs provide 8-bit current sourcing per channel; programmable opamps serve as current-sense amplifiers with rail-to-rail output. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable mixed-signal controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4124LQI-433 | Same core, 40-pin QFN package, lower pin count, no XRES pin, reduced GPIO count (24) | Suitable for space-constrained designs where fewer I/Os and no external reset are acceptable | Select when board area is critical and full 36-GPIO capability is unnecessary. |
| CY8C4245FNI-483 | Enhanced PSoC 4200 variant: 128 kB flash, 16 kB SRAM, USBFS block, higher-speed ADC (1 Msps) | Required for USB-connected devices or applications needing larger firmware footprint and faster sampling | Choose when USB device interface or >32 kB code size is mandatory; not drop-in compatible due to USB PHY and pinout changes. |
Compared with CY8C4124LQI-433 and CY8C4245FNI-483, the CY8C4124PVI-432T offers optimal balance of I/O count (36), package accessibility (48-pin TQFP), and industrial temperature range (–40 °C to +105 °C) for cost-sensitive, medium-complexity embedded controllers requiring CapSense and dual-protocol serial interfaces.

FAQ
What debug interface does CY8C4124PVI-432T support?
CY8C4124PVI-432T uses a two-wire Serial Wire Debug (SWD) interface compliant with Arm CoreSight standards. It supports full programming, breakpoint, and watchpoint debugging without requiring JTAG pins. The SWDCLK and SWDIO pins (Pins 45 and 46 in TQFP) are dedicated and cannot be reassigned to GPIO functions.
Does CY8C4124PVI-432T support USB connectivity?
No, CY8C4124PVI-432T does not include a USB physical layer (PHY) or USB controller. It lacks USBFS or USBOTG blocks. For USB-enabled designs, consider the PSoC 4200 family (e.g., CY8C4245FNI-483) which integrates USBFS with full device/host capability and dedicated USB I/O pins.
Can the SAR ADC operate during Deep Sleep mode?
Yes, the 12-bit SAR ADC can perform conversions in Deep Sleep mode using the internal ILO clock. Channel sequencing and signal averaging remain functional, and conversion completion triggers a wakeup interrupt. However, flash access and CPU execution are suspended until exit from Deep Sleep.
How many CapSense electrodes can CY8C4124PVI-432T support?
CY8C4124PVI-432T supports up to 36 self-capacitance or 28 mutual-capacitance electrodes using its dedicated CSD block. Electrode count depends on routing constraints and scan time requirements; full 36-electrode operation is verified in the CY8C4124PVI-432T datasheet (Rev. *K, Table 10-1) with SmartSense™ enabled.
