Product details
Overview
CY8C4045AZI-S413 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 V to 5.5 V and supports Deep Sleep mode at 2.5 µA digital current. Used in touch-enabled industrial HMI and smart appliance control systems.
For engineers reviewing the CY8C4045AZI-S413 datasheet, CY8C4045AZI-S413 pinout, CY8C4045AZI-S413 application, or CY8C4045AZI-S413 equivalent, key selection criteria include CAPSENSE™ SNR (>5:1), programmable analog (IDACs, low-power comparators), TCPWM kill-signal triggering, and WLCSP-25 package compatibility for space-constrained designs.
Technical Context
The device integrates a single-cycle multiply Arm® Cortex®-M0+ core with tightly coupled flash read accelerator and 8 KB ROM containing boot code and PDL routines. System-level resources include SWD debug interface, NVIC with IRQMUX, and power management with IMO/ILO/WCO clock sources.
Analog subsystem features capacitive sigma-delta sensing (v2) with SmartSense auto-tuning, two current DACs usable on any GPIO, and dual low-power comparators operational in Deep Sleep. Digital fabric includes five TCPWM blocks supporting center-aligned PWM and comparator-triggered kill signals for motor safety logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0+, 48 MHz max - enables real-time deterministic control with minimal latency for sensor fusion and timing-critical peripherals. |
| Memory | 32 KB flash + 4 KB SRAM - sufficient for CAPSENSE™ firmware, communication stacks, and small RTOS deployments without external memory. |
| CAPSENSE™ | Sigma-delta v2 with >5:1 SNR and water tolerance - delivers robust touch performance in humid or wet environments without shielding. |
| TCPWM Blocks | 5 × 16-bit timer/counter/PWM - supports motor control with center-aligned PWM and hardware kill-signal generation via comparator input. |
| SCBs | 2 × reconfigurable serial blocks - each can be independently set as I²C, SPI, or UART at runtime, enabling flexible peripheral connectivity. |
| Power Modes | Deep Sleep @ 2.5 µA digital current - allows battery-powered devices to maintain wake-on-touch capability for months on coin-cell power. |
| GPIO | Up to 36 pins, all CAPSENSE™/analog/digital configurable - eliminates need for external signal routing logic in compact HMI designs. |
Pinout & Package
Package: 25-ball WLCSP (Wafer-Level Chip Scale Package), 2.13 mm × 2.13 mm, 0.4 mm pitch, bottom-side solder balls. Designed for ultra-compact PCB layouts and high-density consumer electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Core & I/O supply | 1.71–5.5 V input; powers digital logic, analog blocks, and GPIO drivers - single-rail simplifies power design. |
| VSS | Digital ground | Reference return for digital circuitry and SWD interface - must be low-impedance connection to minimize noise coupling. |
| XRES | External reset input | Active-low asynchronous reset; debounced internally - enables reliable system recovery without external RC network. |
| SWDIO / SWCLK | Debug interface | Two-pin serial-wire debug - supports full programming, breakpoint, and trace without JTAG header footprint. |
| P0[0]–P0[7] | Programmable GPIO | Port 0 pins support CAPSENSE™, analog input/output, or digital logic - configurable drive strength/slew rate per pin. |
Key Features
| Feature | Design Value |
|---|---|
| SmartSense auto-tuning | Hardware-accelerated CAPSENSE™ calibration eliminates manual tuning and compensates for environmental drift in production. |
| Reconfigurable SCBs | Each serial block dynamically switches between I²C, SPI, and UART protocols in firmware - reduces BOM count and PCB layer count. |
| Deep Sleep with active analog | Low-power comparators remain functional while CPU and most digital logic are powered down - enables wake-on-touch with sub-µA quiescent current. |
| Programmable I/O matrix | Any GPIO can route to any analog or digital peripheral - avoids fixed-function pin conflicts and simplifies layout iteration. |
| Integrated ROM bootloader | 8 KB ROM contains certified PDL and secure boot routines - enables field firmware updates without external host or flash driver development. |

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-S412 | Same core and peripherals but in 40-pin QFN package (5 × 5 mm) - no WLCSP footprint compatibility. | Preferred for prototyping and hand-soldered boards where board space is less constrained. | Select when PCB assembly process does not support 0.4 mm pitch WLCSP or when thermal dissipation requirements exceed WLCSP limits. |
| CY8C4146AZI-S433 | Higher flash (64 KB), added USBFS block, same WLCSP-25 package - no CAPSENSE™ v2 or SmartSense. | Suitable for USB-connected embedded controllers needing firmware update over USB, not touch-centric HMI. | Choose only if USB device interface is mandatory and CAPSENSE™ performance is secondary to code size and connectivity. |
Compared with CY8C4045LQI-S412 and CY8C4146AZI-S433, the CY8C4045AZI-S413 uniquely balances ultra-compact WLCSP packaging, best-in-class CAPSENSE™ SNR, and hardware auto-tuning - making it optimal for volume-manufactured touch interfaces where size, reliability, and production calibration time are critical.

FAQ
Does CY8C4045AZI-S413 support USB device functionality?
No. This part lacks a USBFS block. USB connectivity requires higher-tier PSoC™ 4 variants such as CY8C4146AZI-S433 or PSoC™ 6 devices. The CY8C4045AZI-S413 relies on its two SCBs for I²C, SPI, or UART communication only.
What is the maximum operating temperature for CY8C4045AZI-S413?
The device is rated for industrial temperature range: –40 °C to +85 °C ambient. This is specified in the Absolute Maximum Ratings table (Section 6.1) and confirmed in the Ordering Information (Section 7) as "I" grade, with "ZI" suffix denoting the WLCSP package and industrial temp grade.
Can CAPSENSE™ operate during Deep Sleep mode?
Yes. The capacitive sigma-delta sensing block and associated low-power comparators remain active in Deep Sleep mode. The device can detect touch events and wake the CPU with sub-millisecond latency while maintaining 2.5 µA system current.
Is ModusToolbox™ required for development with CY8C4045AZI-S413?
No. Both ModusToolbox™ and the legacy PSoC™ Creator IDE fully support this device. PSoC™ Creator remains actively maintained for PSoC™ 4 and provides schematic-based design entry, while ModusToolbox™ offers modern CLI-driven workflows and GitHub-integrated code examples.
