Product details
Overview
CY8C4045AZI-S413T from Infineon is a 32-bit Arm® Cortex®-M0+ microcontroller with 48 MHz CPU, 32 KB flash, 4 KB SRAM, integrated CAPSENSE™ capacitive sensing, two SCBs supporting I²C/SPI/UART, and five 16-bit TCPWM blocks. It operates from 1.71–5.5 V and supports Deep Sleep mode at 2.5 µA digital current. Used in touch-enabled human-machine interfaces for industrial control panels and consumer appliances.
For engineers reviewing the CY8C4045AZI-S413T datasheet, CY8C4045AZI-S413T pinout, CY8C4045AZI-S413T application, or CY8C4045AZI-S413T equivalent, key selection criteria include CAPSENSE™ SNR (>5:1), programmable analog (IDACs, comparators), TCPWM kill-signal triggering, and 36 GPIO flexibility across QFN/TQFP/WLCSP packages.
Technical Context
The device integrates a single-cycle multiply Arm® Cortex®-M0+ core with dedicated hardware-accelerated CAPSENSE™ v2 sigma-delta sensing engine delivering >5:1 SNR and water-tolerant operation. Its analog subsystem includes two low-power comparators active in Deep Sleep and two current DACs routable to any GPIO.
Digital resources comprise five TCPWM blocks supporting center-aligned PWM, comparator-triggered kill signals for motor safety, and two reconfigurable serial communication blocks (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 real-time deterministic control with single-cycle multiply for motor or sensor math. |
| Memory | 32 KB flash + 4 KB SRAM - sufficient for CAPSENSE™ firmware, TCPWM control loops, and dual-protocol SCB stacks. |
| Capacitive Sensing | CAPSENSE™ v2 sigma-delta with SmartSense auto-tuning - eliminates manual calibration and maintains reliability under moisture or EMI. |
| Analog Peripherals | 2× IDACs (up to 2 mA), 2× low-power comparators - support self-capacitance/proximity sensing and wake-on-event in Deep Sleep. |
| Digital Peripherals | 5× TCPWM, 2× SCB, 36 GPIO - enables concurrent motor control (PWM), communication (I²C display + UART debug), and multi-channel touch sensing. |
| Power Modes | Deep Sleep @ 2.5 µA digital + operational analog - sustains capacitive wake detection while minimizing battery drain in portable HMI. |
Pinout & Package
This device is packaged in a 40-pin QFN (7 mm × 7 mm, 0.5 mm pitch) with exposed thermal pad. Pin functions are fully configurable via PSoC™ Creator or ModusToolbox™, and all GPIOs support CAPSENSE™, analog, or digital roles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Core & I/O supply | 1.71–5.5 V input; powers CPU, SRAM, and all digital/analog blocks. |
| VSS | Ground reference | Common return path for analog/digital domains; requires low-impedance PCB connection. |
| P0[0]–P0[7] | Programmable GPIO | Support CAPSENSE™, IDAC output, comparator input, or SCB signal routing. |
| SWDCLK / SWDIO | Debug interface | ARM Serial Wire Debug pins - enable full on-chip debugging without external emulators. |
| XRES | External reset | Active-low asynchronous reset input; debounced internally for robust system recovery. |
Key Features
| Feature | Design Value |
|---|---|
| SmartSense auto-tuning | Hardware-accelerated CAPSENSE™ calibration eliminates manual threshold tuning and adapts to environmental drift. |
| Reconfigurable SCBs | Each SCB can be independently assigned as I²C master/slave, SPI master/slave, or UART - reduces BOM count vs. discrete protocol ICs. |
| TCPWM kill-input trigger | Comparator output directly disables PWM output in <100 ns - meets functional safety timing for motor overcurrent protection. |
| Deep Sleep analog retention | Comparators and CAPSENSE™ remain active during 2.5 µA Deep Sleep - enables always-on touch wake without host CPU intervention. |
Applications
| Industrial HMI Panel | Smart Appliance Control |
|---|---|
Use Scenario: Touch-based operator interface on factory HMIs with metal bezel and ambient moisture exposure. IC Role / Device Role / Timing Role: Primary MCU executing CAPSENSE™ scan, driving segmented LCD, and managing Modbus RTU over UART. Use Value: CAPSENSE™ v2's >5:1 SNR and water tolerance ensure reliable touch detection despite condensation or cleaning fluids. | Use Scenario: Integrated control unit in washing machines with rotary encoder emulation and motor phase control. IC Role / Device Role / Timing Role: Real-time motor controller using TCPWM center-aligned PWM and comparator-triggered fault shutdown. Use Value: Sub-100 ns kill-signal response prevents IGBT shoot-through during overcurrent events. |
| Portable Medical Device | Home Automation Hub |
Use Scenario: Battery-powered patient monitor with capacitive buttons and low-power status LED indicators. IC Role / Device Role / Timing Role: System controller managing touch input, LED dimming via PWM, and BLE UART bridge. Use Value: 2.5 µA Deep Sleep with active comparators extends battery life to >2 years on coin cell. | Use Scenario: Central hub coordinating Zigbee/Z-Wave radios, touch controls, and relay drivers for lighting zones. IC Role / Device Role / Timing Role: Application processor handling CAPSENSE™ UI, SCB-based radio interface, and TCPWM-driven zero-cross detection. Use Value: Single-chip integration of touch, comms, and timing reduces board area by 35% vs. discrete MCU + touch controller + timer IC. |
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 |
|---|---|---|---|
| CY8C4045LQI-S403 | Same core/peripherals but in 32-pin QFN; lacks 4 GPIOs and one SCB. | Suitable for space-constrained designs with reduced I/O and single-protocol comms. | Select when footprint and cost outweigh need for dual SCBs or full 36-GPIO flexibility. |
| CY8C4146AZI-S433 | Higher flash (64 KB), added USBFS block, same CAPSENSE™ and TCPWM features. | Required for USB-connected devices needing HID or CDC class enumeration. | Choose when USB device connectivity is mandatory and additional memory supports larger firmware stacks. |
Compared with CY8C4045LQI-S403, the CY8C4045AZI-S413T provides two full SCBs and 4 extra GPIOs for complex HMI + comms integration; versus CY8C4146AZI-S433, it trades USB for lower cost and power, making it optimal for battery-powered touch interfaces without host connectivity.

FAQ
What development tools support CY8C4045AZI-S413T?
Infineon officially supports both ModusToolbox™ (cross-platform, Eclipse-based) and PSoC™ Creator (Windows-only, schematic-driven). Both provide full CAPSENSE™ configuration, TCPWM setup, and SCB protocol assignment. MiniProg4 is the recommended programmer/debugger, and CY8CKIT-145-40XX serves as the validated prototyping kit.
Does CY8C4045AZI-S413T support hardware encryption?
No. This part does not include dedicated cryptographic accelerators or secure boot ROM. It relies on software-based AES/SHA implementations in firmware. For hardware security, consider Infineon's PSoC™ 6 family, which integrates TRNG, PKA, and secure bootloader.
Can all 36 GPIOs be used simultaneously for CAPSENSE™?
No. While all GPIOs are CAPSENSE™-capable, practical limits depend on scan time and SNR requirements. The datasheet specifies up to 24 simultaneous sensors with >5:1 SNR using default SmartSense settings; higher counts require trade-offs in resolution or scan rate.
Is the WCO (32 kHz watch crystal oscillator) required for Deep Sleep operation?
No. The internal 32 kHz ILO (low-power oscillator) suffices for Deep Sleep timing and wake-up intervals. The WCO is optional and improves RTC accuracy to ±20 ppm but consumes more current and requires external crystal placement.
