Product details
Overview
CY8C4147AZI-S445 from Infineon Technologies (acquired Cypress Semiconductor) is a PSoC 4100S Plus programmable system-on-chip featuring a 48-MHz Arm Cortex-M0+ CPU, 128 KB flash, 16 KB SRAM, integrated CapSense® capacitive sensing, CAN 2.0B interface, and programmable analog/digital blocks. It operates from 1.71–5.5 V, supports Deep Sleep at 2.5 µA, and targets embedded human-interface and industrial control applications with mixed-signal reconfigurability.
For engineers reviewing the CY8C4147AZI-S445 datasheet, CY8C4147AZI-S445 pinout, CY8C4147AZI-S445 application, or CY8C4147AZI-S445 equivalent, key selection criteria include its 44-pin TQFP package, 54 GPIOs with CapSense/analog/digital flexibility, CAN 2.0B + TRNG + SmartSense™ auto-tuning, and compatibility with PSoC Creator IDE for hardware/firmware co-design.
Technical Context
The device integrates an Arm Cortex-M0+ core with tightly coupled flash (128 KB, Read Accelerator) and SRAM (16 KB, zero wait-state), enabling deterministic real-time execution. Its programmable analog subsystem includes two opamps (Deep Sleep-capable), a 12-bit 1-Msps SAR ADC with channel sequencer, and two IDACs-supporting high-precision sensor front-ends and self-capacitive touch sensing.
Digital resources comprise five reconfigurable Serial Communication Blocks (SCBs) supporting I²C/SPI/UART, eight 16-bit TCPWM blocks with quadrature decode and comparator-triggered kill signals, and a dedicated CAN 2.0B controller with Time-Triggered CAN (TTCAN) support-enabling robust motor control and automotive-grade communication.

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 |
|---|---|---|---|
| CY8C4147LQI-S433 | Same PSoC 4100S Plus family, 48-pin QFN package, identical peripherals but different pin mapping and thermal characteristics. | Preferred for space-constrained PCBs requiring fine-pitch soldering and higher thermal dissipation. | Select when board layout favors QFN over TQFP and thermal management is critical. |
| STM32G474RET6 | Arm Cortex-M4F core, 512 KB flash, no integrated CapSense; includes FPU and advanced timers but lacks programmable analog blocks. | Better suited for math-intensive control loops but requires external touch controller and analog signal chain components. | Choose when floating-point computation dominates and CapSense integration is not required. |
Compared with CY8C4147LQI-S433, the CY8C4147AZI-S445 offers TQFP ease-of-handling and legacy footprint compatibility; versus STM32G474RET6, it delivers full analog/digital reconfigurability in one die-reducing BOM count and layout complexity for CapSense-centric designs.

FAQ
What development tools are required to program and debug CY8C4147AZI-S445?
PSoC Creator IDE (free Windows-based tool) is the primary development environment, providing schematic-based hardware design, automatic routing, and API-driven firmware generation. Programming and debugging use the standard Arm Serial-Wire Debug (SWD) interface with MiniProg3 or KitProg2 programmers-no JTAG adapter needed. Third-party Arm tools (Keil, IAR, GCC) are also supported after initial project setup.
Does CY8C4147AZI-S445 support capacitive touch through glass or plastic overlays?
Yes-its CapSense Sigma-Delta (CSD) engine achieves >5:1 signal-to-noise ratio and includes hardware-based SmartSense™ auto-tuning, enabling reliable touch detection through up to 8 mm of glass or 5 mm of plastic. The CSD block dynamically adjusts scan parameters to compensate for overlay thickness, moisture, and EMI-eliminating manual calibration during production.
Can the CAN peripheral operate independently of the CPU during Deep Sleep mode?
No-the CAN block requires the HFCLK and is disabled in Deep Sleep mode. However, wake-up events (e.g., CAN message reception) can be configured to trigger exit from Deep Sleep via the Wakeup Interrupt Controller (WIC), resuming full CAN operation within 35 µs. For true autonomous CAN filtering, external CAN controllers with sleep-wake capability are required.
How is flash security enforced on CY8C4147AZI-S445?
Flash protection is implemented via hardware lock bits that prevent read-out or reprogramming once set. Debug access can be permanently disabled by clearing the SWD enable bit in the protection register-requiring full chip erase to restore. All programming interfaces (SWD, bootloader) are disabled when maximum device security is activated, making forensic analysis impossible without destructive decapsulation.
