Product details
Overview
CY8C4745AZI-S413 from Infineon Technologies (formerly Cypress Semiconductor) is a programmable 32-bit Arm® Cortex®-M0+ microcontroller in the PSoC 4700S family, integrating MagSense™ inductive sensing and CapSense® capacitive sensing on a single die. It features 48 MHz CPU, 32 KB flash, 4 KB SRAM, up to 16 inductive sensors, and dual reconfigurable SCBs supporting I²C/SPI/UART. It targets metal proximity detection in industrial HMI and touchless control systems.
For engineers reviewing the CY8C4745AZI-S413 datasheet, CY8C4745AZI-S413 pinout, CY8C4745AZI-S413 application, or CY8C4745AZI-S413 equivalent, key selection criteria include its integrated MagSense capability for sub-190 nm metal deflection detection, CapSense Sigma-Delta SNR >5:1 with water tolerance, Deep Sleep current of 2.5 µA, 1.71–5.5 V operation, and TCPWM-based motor kill-signal triggering.
Technical Context
The CY8C4745AZI-S413 implements a tightly coupled Arm Cortex-M0+ subsystem with 48 MHz clocking via trimmed IMO (±2% accuracy), supported by fractional clock dividers for precise peripheral timing. Its analog subsystem includes two low-power comparators operational in Deep Sleep mode and a single-slope 10-bit ADC with configurable reference.
Digital resources include five 16-bit TCPWM blocks with center-aligned/edge/pseudo-random PWM modes and comparator-triggered kill signals for motor safety, plus two SmartIO ports enabling Boolean logic on GPIOs without CPU intervention. The device uses a single-layer AHB interconnect and supports concurrent analog/digital routing via PSoC Creator.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0+, 48 MHz - enables real-time sensor fusion and deterministic interrupt response in embedded HMI applications. |
| Flash / SRAM | 32 KB flash with Read Accelerator / 4 KB SRAM - supports firmware updates and local sensor data buffering without external memory. |

Pinout & Package
Package: 48-pin TQFP (7 mm × 7 mm, 0.5 mm pitch), RoHS-compliant, lead-free, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Primary power supply input | Accepts 1.71–5.5 V; powers digital core, analog blocks, and I/O; requires local decoupling per datasheet layout guidelines. |
| VSS | Ground reference | Digital and analog ground return; must be connected to low-impedance PCB plane to maintain MagSense/CapSense noise immunity. |

Key Features
| Feature | Design Value |
|---|---|
| MagSense™ inductive sensing | Enables contactless metal detection with factory-calibrated compensation for coil tolerance and PCB variation-no external components required. |
| CapSense® Sigma-Delta (CSD) | Delivers >5:1 signal-to-noise ratio and intrinsic water tolerance, eliminating need for overlay shielding or firmware-based noise rejection algorithms. |
| SmartIO programmable logic | Permits Boolean operations (AND/OR/XOR) directly on GPIO inputs/outputs-offloads simple state-machine logic from CPU to reduce latency and power. |
| TCPWM kill-signal triggering | Hardware-level PWM shutdown initiated by comparator output-ensures sub-microsecond response for motor overcurrent or fault conditions. |
| Deep Sleep with active analog | Maintains MagSense/CapSense monitoring and comparator wake-up at 2.5 µA system current-enables always-on sensing in energy-constrained devices. |

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 |
|---|---|---|---|
| CY8C4745AZI-S412 | Same die, identical specs, but shipped in tape-and-reel instead of tray; no functional difference. | Identical use cases; selected only for automated SMT assembly compatibility. | Choose S412 for high-volume pick-and-place production; S413 remains optimal for prototyping and low-volume builds. |
| CY8C4745LQI-S413 | Same architecture but in 40-pin QFN package; 4 fewer GPIOs and no LCD segment drive capability. | Suitable for space-constrained designs where inductive sensing count ≤12 and LCD is unused. | Select LQI-S413 when board area is critical and full 36-GPIO count or LCD drive is unnecessary. |
Compared with CY8C4745AZI-S413, the S412 offers identical functionality in tape-and-reel packaging for production lines, while the LQI-S413 trades GPIO count and LCD support for smaller footprint-making the S413 optimal for development, evaluation, and applications requiring maximum I/O flexibility and display integration.

FAQ
What development tools are required to program the CY8C4745AZI-S413?
PSoC Creator IDE (free, Windows-only) is the official development environment, providing schematic-based hardware design, automatic routing, and pre-verified CapSense/MagSense components. Programming is performed via SWD interface using MiniProg3 or KitProg2 programmers. Arm GCC toolchain integration is supported for advanced firmware development outside PSoC Creator.
Does the CY8C4745AZI-S413 support hardware encryption or secure boot?
No. The CY8C4745AZI-S413 does not include dedicated cryptographic accelerators, TRNG, or secure boot ROM. It relies on software-based AES libraries and external secure elements for confidentiality-critical applications. Its security model focuses on tamper-resistant debug disable and flash protection bits-not hardware root-of-trust.
Can MagSense and CapSense operate simultaneously on the same GPIO pin?
No. While both sensing modalities share the same GPIO structure, they cannot run concurrently on a single pin due to conflicting analog front-end configurations. Pins must be statically assigned to either MagSense (inductive) or CapSense (capacitive) mode during design time in PSoC Creator.
What is the maximum operating temperature rating for the CY8C4745AZI-S413?
The CY8C4745AZI-S413 is rated for operation from −40°C to +105°C ambient temperature (Industrial Grade), verified per AEC-Q100 stress testing standards. This rating applies to the full 1.71–5.5 V supply range and all specified peripheral functions including MagSense and CapSense.
