Product details
Overview
CY8C4147AZQ-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 - deployed in industrial HMI, smart sensor nodes, and motor control edge devices.
For engineers reviewing the CY8C4147AZQ-S445 datasheet, CY8C4147AZQ-S445 pinout, CY8C4147AZQ-S445 application, or CY8C4147AZQ-S445 equivalent, key selection criteria include Deep Sleep current (2.5 µA), SAR ADC resolution (12-bit @ 1 Msps), CapSense SNR (>5:1), CAN 2.0B compliance, and TQFP-44 package compatibility with Arduino-compatible prototyping kits.
Technical Context
The device integrates a single-core Arm Cortex-M0+ with tightly coupled flash accelerator and 8-channel DMA, enabling deterministic real-time control. Its clock architecture combines IMO (±2%), WCO (32 kHz), ECO (4–33 MHz), and PLL to generate stable 48-MHz system clock with glitch-free switching.
Analog subsystem includes two opamps operable in Deep Sleep, a 12-bit SAR ADC with channel sequencer and averaging, two IDACs, and two low-power comparators - all routed via programmable interconnect to any of 54 GPIOs. The dedicated CapSense Sigma-Delta (CSD) block delivers water-tolerant touch sensing without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0+, 48 MHz - enables deterministic real-time firmware execution with Thumb-2 instruction set and single-cycle multiply. |
| Flash Memory | 128 KB with Read Accelerator - supports zero-wait-state code execution at 48 MHz for latency-critical ISR handling. |
| SRAM | 16 KB, zero wait-state - sufficient for dual-buffered CAN message queues and CapSense raw data storage. |
| ADC | 12-bit SAR, 1 Msps, differential mode - resolves ±1 LSB INL for precision sensor signal acquisition in industrial transducers. |
| CapSense SNR | >5:1 - ensures reliable touch detection under wet conditions and EMI noise in appliance control panels. |
| CAN Interface | CAN 2.0B with TTCAN support - provides time-triggered messaging for synchronized actuator control in motor drives. |
| Deep Sleep Current | 2.5 µA - enables multi-year battery life in wireless sensor endpoints with periodic wake-up via WCO or comparator event. |
Pinout & Package
Package: 44-pin TQFP (0.8-mm pitch), RoHS-compliant, body size 10 × 10 mm, exposed thermal pad.
| 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 banks - requires local 100-nF decoupling. |
| VSS | Ground reference | Digital and analog ground return; must be connected to low-impedance PCB plane for CapSense noise immunity. |
| P0[0]–P0[7] | Programmable GPIO bank | Support CapSense CSD, analog input, UART TX/RX, or PWM output - configurable slew rate and drive strength per pin. |
| SWDCLK / SWDIO | Serial Wire Debug interface | Two-pin debug port for programming and full-chip debugging; enabled by default, disableable via firmware for security. |
| CAN_TX / CAN_RX | CAN physical layer interface | Differential pair routed to external CAN transceiver; supports 1 Mbps operation with internal termination control. |
| XRES | External reset input | Active-low asynchronous reset; debounced internally; overrides all power modes including Deep Sleep. |
Key Features
| Feature | Design Value |
|---|---|
| SmartSense™ auto-tuning | Hardware-accelerated CapSense calibration eliminates manual parameter tuning across temperature/humidity variations. |
| Programmable analog routing | Connects opamp outputs directly to SAR ADC inputs or IDACs without PCB traces - reduces noise and layout complexity. |
| True Random Number Generator (TRNG) | Meets NIST SP 800-90B entropy requirements for secure key generation in bootloader authentication. |
| Device security lockdown | Permanent disable of SWD, flash read, and programming interfaces - prevents firmware extraction or malicious reprogramming. |
| Quadrature decoder | Hardware TCPWM block implementation - enables precise position/speed measurement from incremental encoders without CPU overhead. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32G474RET6 | ARM Cortex-M4F core, no integrated CapSense, higher 170 µA/MHz active current | Lacks hardware touch engine; requires external IC or software-based touch algorithm with lower SNR | Select when floating-point math or USB-C PD control is required, not when robust wet-touch UI is primary requirement |
| RP2040 | Dual-core ARM Cortex-M0+, no CAN, no TRNG, no analog peripherals beyond basic ADC | No CAN 2.0B or CapSense - unsuitable for industrial fieldbus or touch HMI applications | Select for cost-sensitive consumer IoT where USB mass storage boot and dual-core threading outweigh analog/CAN needs |
Compared with STM32G474RET6 and RP2040, CY8C4147AZQ-S445 uniquely integrates CapSense, CAN, and programmable analog in a single die - eliminating external components for touch + fieldbus + sensor conditioning in space-constrained industrial edge nodes.

FAQ
Does CY8C4147AZQ-S445 support hardware encryption acceleration?
No. CY8C4147AZQ-S445 does not include dedicated AES or SHA hardware accelerators. It relies on software libraries (e.g., Mbed TLS) executed on the Cortex-M0+ core. However, its True Random Number Generator (TRNG) meets NIST SP 800-90B entropy requirements for secure key derivation in cryptographic operations.
Can the CapSense block operate during Deep Sleep mode?
Yes. The CapSense Sigma-Delta (CSD) block remains fully functional in Deep Sleep mode with only 2.5 µA total system current. It can autonomously scan up to 16 sensors and trigger a wake-up interrupt upon touch detection - enabling ultra-low-power wake-on-touch functionality without CPU involvement.
What is the maximum allowed ECO frequency range for CY8C4147AZQ-S445?
The external crystal oscillator (ECO) supports frequencies from 4 MHz to 33 MHz, as specified in the PSoC 4100S Plus datasheet (Document 002-19966 Rev. *H). Operation outside this range may cause clock instability or failure to start, and is not characterized or guaranteed by Infineon.
Is the CAN block compliant with ISO 11898-1:2015?
Yes. The CAN 2.0B block implements full ISO 11898-1:2015 physical layer signaling compliance, including recessive-dominant bit arbitration, error frame generation, and TTCAN time-triggered scheduling. It requires an external CAN transceiver (e.g., TJA1042T) for bus-level interfacing.
