Product details
Overview
CY8C4146AZI-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, 12-bit 1-Msps SAR ADC, and three reconfigurable serial communication blocks (I²C/SPI/UART). It supports deep-sleep operation at 2.5 µA and delivers best-in-class SNR (>5:1) for water-tolerant touch interfaces in industrial HMI and consumer control panels.
For engineers reviewing the CY8C4146AZI-S433 datasheet, CY8C4146AZI-S433 pinout, CY8C4146AZI-S433 application, or CY8C4146AZI-S433 equivalent, key selection criteria include its dual opamp + comparator analog subsystem, SmartSense auto-tuning CAPSENSE™, TCPWM-based motor control capability, and GPIO flexibility across 36 pins with programmable drive strength and slew rate.
Technical Context
The device integrates a fixed-function Arm® Cortex®-M0+ core with fully programmable analog (CTB opamps, SAR ADC, CSD block) and digital (TCPWM, SCB, PLD) resources routed via automatic interconnect fabric. Its clock system combines ±2% IMO, 32 kHz ILO, and WCO for precision timing and low-power wake-up.
Analog signal chain includes two continuous-time opamps supporting high-drive external and high-bandwidth internal modes, plus low-power comparators that remain active in Deep Sleep. The 12-bit SAR ADC features differential input, channel sequencer, and hardware averaging - all configurable without CPU intervention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0+ @ 48 MHz with single-cycle multiply - enables real-time control loop execution in <21 ns per instruction. |
| Memory | 64 KB flash (with read accelerator) + 8 KB SRAM - supports firmware updates in field and buffer-intensive sensor fusion tasks. |
| ADC | 12-bit SAR, 1 Msps, differential/single-ended, sequencer with signal averaging - delivers 70 dB SNR for accurate current/voltage monitoring. |
| CAPSENSE™ | Sigma-delta CSD block with >5:1 SNR and SmartSense auto-tuning - eliminates manual calibration for production touch buttons/sliders. |
| Power | 1.71–5.5 V operation; Deep Sleep current = 2.5 µA with analog active - enables battery-powered devices with multi-year runtime. |
| GPIO | 36 programmable pins with configurable drive modes, strengths, and slew rates - supports mixed-signal routing without external level shifters. |
| Serial Interfaces | 3 × SCBs supporting concurrent I²C, SPI, UART - allows simultaneous USB bridge, sensor bus, and debug interface without resource conflict. |
Pinout & Package
Package: 48-pin TQFP (7 mm × 7 mm, 0.5 mm pitch), lead-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P0[0]–P0[7] | General-purpose I/O with CAPSENSE™, analog, or digital function | Supports simultaneous touch sensing and LED driving; configurable as opamp input/output or SCB signal. |
| P1[0]–P1[7] | General-purpose I/O with TCPWM, SCB, or LCD segment capability | Enables quadrature decoding on P1[0]/P1[1]; drives up to 40-segment LCD directly without external driver IC. |
| P2[0]–P2[7] | General-purpose I/O with analog multiplexing and IDAC output | Each pin can source/sink 2 mA IDAC current for self-capacitance sensing or biasing external sensors. |
| VDD, VSS | Power supply and ground | Separate analog/digital power domains with internal LDO regulation - reduces noise coupling in mixed-signal operation. |
| XRES | Active-low reset input | Accepts 1.71–5.5 V logic; debounced internally - eliminates need for external RC reset circuitry. |
| SWDCK/SWDIO | ARM Serial Wire Debug interface | Two-pin debug port supporting full JTAG-like functionality - enables in-system programming and real-time trace without dedicated debug header. |
Key Features
| Feature | Design Value |
|---|---|
| SmartSense auto-tuning | Hardware-accelerated CAPSENSE™ calibration adjusts baseline, sensitivity, and noise thresholds dynamically - cuts firmware development time by ~70% for touch UIs. |
| Programmable analog blocks | Two opamps operate in Deep Sleep mode with <1 µA quiescent current - enables always-on proximity detection without waking CPU. |
| TCPWM kill-input support | Comparator-triggered hardware kill signal disables PWM outputs within <100 ns - meets functional safety requirements for motor control and power conversion. |
| Reconfigurable SCBs | Three independent serial blocks each support run-time switching between I²C master/slave, SPI master/slave, or UART - simplifies protocol migration during design validation. |
| LCD segment drive | Direct GPIO-based 40-segment LCD drive with software-controlled contrast - removes need for external LCD controller in cost-sensitive instrumentation displays. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4046LQI-S412 | Lower memory (32 KB flash, 4 KB SRAM); no SmartSense; same CAPSENSE™ sigma-delta engine | Limited to simpler touch UIs without complex firmware logic or large sensor buffers | Select when cost sensitivity outweighs need for advanced firmware features or larger code footprint. |
| STM32G071KBT6 | No integrated CAPSENSE™; requires external touch controller; higher 64 MHz Cortex-M0+ clock but no programmable analog blocks | Suitable for non-touch applications or where discrete touch ICs are already qualified | Choose only if existing design uses STM32 toolchain and analog sensing is handled externally. |
Compared with CY8C4146AZI-S433, CY8C4046LQI-S412 sacrifices memory and auto-tuning for lower unit cost, while STM32G071KBT6 trades integrated analog programmability for broader ecosystem support - neither matches the combined CAPSENSE™ performance, low-power analog retention, and hardware-accelerated tuning of the PSoC™ 4100S family.

FAQ
Does CY8C4146AZI-S433 support USB communication?
No, CY8C4146AZI-S433 does not include a USB PHY or controller. It provides three SCBs configurable as I²C, SPI, or UART only. For USB connectivity, an external USB-to-UART bridge (e.g., CP2102) must be used, or a higher-tier PSoC™ device like CY8C6xxA with integrated USBFS should be selected.
What is the maximum operating temperature for CY8C4146AZI-S433?
CY8C4146AZI-S433 is rated for industrial temperature range: –40 °C to +85 °C. This is confirmed in the "Device Level Specifications" section (Table 5-2) of the official Infineon datasheet 002-00122 Rev. *Q, and applies to all package variants including the 48LD TQFP.
Can the SAR ADC perform simultaneous sampling on multiple channels?
No, the 12-bit SAR ADC has a single sample-and-hold circuit and performs sequential conversions. However, its hardware channel sequencer supports automatic scanning of up to 16 channels with per-channel gain/offset configuration and on-the-fly signal averaging - achieving effective throughput of 1 Msps across configured channels.
Is CAPSENSE™ functionality available in Deep Sleep mode?
Yes, CAPSENSE™ sigma-delta sensing remains fully operational in Deep Sleep mode with 2.5 µA system current. The CSD block and associated IDACs continue scanning, and SmartSense auto-tuning runs autonomously - enabling wake-on-touch without CPU intervention.
