Product details
Overview
CY8C4147AZE-S445 from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-grade PSoC™ 4100S Plus microcontroller featuring a 48-MHz Arm® Cortex®-M0+ CPU, 128 KB flash, 16 KB SRAM, and integrated CAPSENSE™ capacitive sensing with SmartSense auto-tuning. It includes five reconfigurable serial communication blocks (SCB), eight 16-bit TCPWM units, and a CAN 2.0B controller with time-triggered support - deployed in automotive body control modules requiring robust touch interfaces and real-time bus communication.
For engineers reviewing the CY8C4147AZE-S445 datasheet, CY8C4147AZE-S445 pinout, CY8C4147AZE-S445 application, or CY8C4147AZE-S445 equivalent, key selection criteria include AEC-Q100 Grade-S qualification, on-chip CAPSENSE™ SNR >5:1, CAN 2.0B + TTCAN capability, Deep Sleep current ≤2.5 µA, and GPIO flexibility across 54 pins with programmable drive strength and slew rate.
Technical Context
The device integrates a dual-domain clock system with a 48-MHz PLL-fed core clock, independent 32-kHz WCO for RTC, and ±2% IMO for fast wake-up. Its analog subsystem includes two opamps supporting ADC input buffering and comparator modes, plus a 12-bit 1-Msps SAR ADC with channel sequencer and signal averaging.
Digital resources comprise eight TCPWM blocks supporting center-aligned PWM and quadrature decoding, five SCBs configurable as I²C/SPI/UART/LIN, and a dedicated CAN 2.0B block with TTCAN timing compliance - enabling deterministic motor control and distributed sensor networks in ASIL-B–aligned systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0+, 48 MHz max - enables real-time deterministic execution of automotive firmware stacks including AUTOSAR MCAL drivers. |
| Memory | 128 KB flash (with Read Accelerator), 16 KB SRAM - supports secure boot, OTA update partitions, and runtime data buffering for CAN/CAPSENSE™ co-processing. |
| CAPSENSE™ | Capacitive sigma-delta (CSD) with SNR >5:1 and water tolerance - delivers reliable touch detection in wet/harsh cabin environments without external shielding. |
| CAN Interface | CAN 2.0B + time-triggered CAN (TTCAN) - provides synchronized message scheduling for safety-critical actuator control in body domain ECUs. |
| Power Modes | Deep Sleep mode: 2.5 µA digital + operational analog - sustains capacitive wake-up and CAN bus monitoring while meeting automotive low-power requirements. |
| GPIO | 54 programmable pins, all support CAPSENSE™, analog, or digital functions with configurable drive strength/slew rate - eliminates external level shifters and simplifies PCB routing. |
| ADC | 12-bit SAR, 1 Msps, differential/single-ended, with hardware channel sequencer and signal averaging - enables high-accuracy battery voltage, temperature, and sensor monitoring. |
Pinout & Package
Package: 48-pin QFN (7 mm × 7 mm, 0.5 mm pitch), RoHS-compliant, moisture sensitivity level 3 (MSL3).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDIO0–VDDIO3 | I/O power supply domains | Independent 1.71–5.5 V domains per port group - enable mixed-voltage interfacing (e.g., 3.3 V MCU logic with 5 V analog sensors). |
| P0.0–P9.7 | Programmable GPIO | All 54 pins support CAPSENSE™, analog input/output, or digital logic - no fixed-function pin constraints; routing fully software-defined. |
| CAN_TX / CAN_RX | Dedicated CAN transceiver interface | Hardwired to internal CAN controller - requires external CAN transceiver (e.g., TJA1042) for physical layer compliance. |
| XTAL_IN / XTAL_OUT | External crystal oscillator input/output | Supports 4–33 MHz ECO for precise clocking; required for CAN bit timing accuracy and USB-free synchronization. |
| WCO_IN / WCO_OUT | 32.768 kHz watch crystal interface | Enables low-power RTC operation during Deep Sleep - critical for wake-on-touch and periodic CAN bus monitoring. |
Key Features
| Feature | Design Value |
|---|---|
| SmartSense auto-tuning | Hardware-accelerated CAPSENSE™ calibration eliminates manual tuning and field recalibration - reduces development time by >70% for touch-button and slider designs. |
| Programmable analog blocks | Two opamps with ADC input buffering and comparator modes - enable single-chip sensor signal conditioning (e.g., thermistor amplification + threshold detection) without external opamp ICs. |
| Reconfigurable SCBs | Five serial blocks dynamically switch between I²C/SPI/UART/LIN at runtime - allows flexible peripheral sharing (e.g., SPI for display + UART for debug + LIN for door module comms) from one hardware resource. |
| True Random Number Generator (TRNG) | Dedicated hardware entropy source compliant with NIST SP 800-90B - enables FIPS-compliant key generation for secure bootloader authentication and firmware signing. |
| Quadrature decoder | Built into TCPWM block - directly processes encoder signals for motor position/speed feedback without CPU intervention, freeing M0+ cycles for higher-layer control. |
Applications
| Automotive Door Module | Climate Control Panel |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4147AZI-S445 | Same die, AEC-Q100 Grade-E (–40°C to +125°C), identical peripherals and pinout. | Required for under-hood applications (e.g., engine bay sensors) exceeding +105°C ambient. | Select when extended temperature range is mandated by placement location - no firmware or layout changes needed. |
| SPC560B50L5 | 32-bit Power Architecture e200z0, 64 MHz, 512 KB flash, no integrated CAPSENSE™, requires external touch controller. | Used in legacy automotive clusters where CAN FD and larger memory footprint are prioritized over capacitive UI. | Choose only if existing SPC5 toolchain and AUTOSAR stack compatibility outweigh CAPSENSE™ integration benefits. |
Compared with CY8C4147AZE-S445, the Grade-E variant offers wider thermal margin but same functionality, while the SPC560B50L5 trades integrated touch capability for higher CAN FD bandwidth and legacy ecosystem alignment - making CY8C4147AZE-S445 optimal for cost-sensitive, space-constrained cabin control nodes.
