Product details
Overview
CY8C4146AZQ-S433 from Infineon is a programmable 32-bit Arm® Cortex®-M0+ microcontroller with 48 MHz CPU, 64 KB flash, 8 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 delivers >5:1 SNR for water-tolerant touch interfaces in consumer HMI and industrial control panels.
For engineers reviewing the CY8C4146AZQ-S433 datasheet, CY8C4146AZQ-S433 pinout, CY8C4146AZQ-S433 application, or CY8C4146AZQ-S433 equivalent, this device offers verified TCPWM timing control, SAR ADC acquisition at 1 Msps, configurable SCB serial interfaces (I²C/SPI/UART), and hardware-accelerated SmartSense auto-tuning for production-ready capacitive sensing design.
Technical Context
The device integrates a single-core Arm Cortex-M0+ CPU with tightly coupled flash and SRAM, enabling deterministic real-time execution of mixed-signal firmware. Its programmable analog subsystem includes two opamps supporting high-drive external and high-bandwidth internal modes, plus a 12-bit SAR ADC with differential input and channel sequencer.
Digital flexibility is delivered via five TCPWM blocks (supporting center-aligned PWM, quadrature decoding, and comparator-triggered kill signals) and three reconfigurable SCBs that dynamically switch between I²C, SPI, and UART protocols without firmware reload.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0+, 48 MHz max - enables deterministic real-time control with single-cycle multiply for motor or sensor processing. |
| Flash Memory | 64 KB with read accelerator - supports fast code execution and firmware updates without performance penalty. |
| SRAM | 8 KB - sufficient for dual-buffered ADC acquisition, CAPSENSE™ baseline tracking, and RTOS task stacks. |
| SAR ADC | 12-bit, 1 Msps, differential mode - captures high-fidelity analog sensor data with hardware averaging and sequenced channel scanning. |
| Deep Sleep Current | 2.5 µA - sustains capacitive wake-up detection and RTC operation on battery-powered IoT endpoints. |
| CAPSENSE™ SNR | >5:1 - ensures reliable touch detection under moisture, gloves, or EMI noise in industrial or appliance HMI. |
| TCPWM Blocks | 5 × 16-bit - generate precise center-aligned PWM for BLDC commutation, quadrature decode for rotary encoders, and kill-input safety logic. |
Pinout & Package
48-pin TQFP package (7 mm × 7 mm, 0.5 mm pitch) with full GPIO reconfigurability: all 36 GPIOs support CAPSENSE™, analog input/output, or digital logic functions. Drive strength, slew rate, and pull-up/down are software-configurable per pin.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P0[0]–P0[7] | General-purpose I/O with CAPSENSE™ | Supports self- and mutual-capacitance sensing; configurable as analog input, opamp output, or SCB signal line. |
| P1[0]–P1[7] | General-purpose I/O with TCPWM | Direct routing to TCPWM block inputs/outputs for PWM generation, capture, or quadrature decoding. |
| P2[0]–P2[7] | General-purpose I/O with SCB | Hardware-mapped to SCB0–SCB2 for I²C SDA/SCL, SPI MOSI/MISO/SCLK/SS, or UART TX/RX. |
| VDD, VSS | Power supply rails | Support 1.71–5.5 V operation; decoupling required per Infineon layout guidelines for analog stability. |
| XRES | Active-low reset input | Asynchronous reset with internal pull-up; compatible with external pushbutton or supervisor IC assertion. |
| SWDIO / SWCLK | Debug interface | Two-pin Serial Wire Debug interface for programming and real-time trace without dedicated JTAG pins. |
Key Features
| Feature | Design Value |
|---|---|
| SmartSense Auto-Tuning | Hardware-accelerated CAPSENSE™ calibration eliminates manual tuning; adapts to environmental drift and electrode aging. |
| Reconfigurable SCBs | Three independent serial blocks dynamically assign I²C/SPI/UART functionality at runtime-no pin remapping or PCB change needed. |
| Deep Sleep Analog Operation | Opamps and comparators remain active in Deep Sleep mode, enabling low-power wake-on-touch or analog threshold detection. |
| Programmable CTB Opamps | Two continuous-time opamps support external high-drive (25 mA) or internal high-bandwidth (12 MHz GBW) modes-configurable per application need. |
| LCD Segment Drive | GPIOs double as segment drivers for static or multiplexed LCDs-reduces BOM count in display-integrated HMI designs. |
Applications
| Home Appliance Control Panel | Industrial Human-Machine Interface |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable mixed-signal MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4046LQ-S412 | Lower memory (32 KB flash, 4 KB SRAM); no SmartSense; 10-bit CSD only. | Suitable for cost-sensitive touch-only applications without analog sensor processing or complex firmware. | Select when CAPSENSE™ is primary function and TCPWM/SAR ADC usage is minimal. |
| STM32G071KBT6 | No integrated CAPSENSE™; requires external touch controller; higher 64 MHz CPU but no reconfigurable analog blocks. | Better for pure control tasks with rich peripheral set (USB, advanced timers), but adds BOM complexity for touch. | Select when USB connectivity or deterministic 64 MHz timing outweighs integrated analog/touch benefits. |
Compared with CY8C4146AZQ-S433, CY8C4046LQ-S412 sacrifices memory and SmartSense for lower unit cost, while STM32G071KBT6 trades integrated mixed-signal flexibility for broader standard peripherals and ecosystem scale-making CY8C4146AZQ-S433 optimal for touch-centric embedded systems needing analog integration and ultra-low-power wake capability.

FAQ
Does CY8C4146AZQ-S433 support USB communication?
No, CY8C4146AZQ-S433 does not include a USB PHY or controller. It provides three reconfigurable SCBs supporting I²C, SPI, and UART only. For USB connectivity, an external bridge IC (e.g., CP2102N) or migration to PSoC™ 4000S/4100S+ variants with USBFS is required.
What development tools are officially supported for this device?
Infineon officially supports ModusToolbox™ 3.x for CY8C4146AZQ-S433, including the PDL peripheral driver library, CAPSENSE™ Tuner, and BSPs for evaluation kits like CY8CKIT-146. Legacy PSoC™ Creator is deprecated but remains functional for existing projects.
Can the SAR ADC perform simultaneous sampling on multiple channels?
No, the 12-bit SAR ADC is single-channel with hardware sequencer support-it acquires channels sequentially with programmable delay between conversions. True simultaneous sampling requires external parallel ADCs or devices with multiple independent SAR cores.
Is the 48 MHz CPU frequency achievable across the full 1.71–5.5 V supply range?
Yes, the Arm Cortex-M0+ core operates at up to 48 MHz across the entire 1.71–5.5 V VDD range, validated per Infineon's electrical specifications (Section 5.2). No voltage scaling or frequency derating is required for full-speed operation.
