Product details
Overview
CY8C4147AZS-S285 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 (SCBs), eight TCPWM modules, a CAN 2.0B controller with TTCAN support, and programmable analog blocks for sensor interface in body electronics.
For engineers reviewing the CY8C4147AZS-S285 datasheet, CY8C4147AZS-S285 pinout, CY8C4147AZS-S285 application, or CY8C4147AZS-S285 equivalent, key selection criteria include its AEC-Q100 Grade-S qualification, on-die CAPSENSE™ SNR > 5:1, Deep Sleep current of 2.5 µA, CAN 2.0B + TTCAN capability, and 54 GPIO with configurable drive modes - all critical for automotive interior control and smart sensor node design.
Technical Context
This device implements a tightly integrated mixed-signal SoC architecture where the Arm® Cortex®-M0+ core executes firmware while programmable analog (CTB, SAR ADC, IDACs) and digital (TCPWM, SCB, Smart I/O) blocks operate under hardware-configured routing. Its clock system combines a 4–33 MHz ECO, PLL, WCO, and ±2% IMO to support deterministic real-time timing across sleep/wake transitions.
The CAPSENSE™ subsystem uses capacitive sigma-delta (CSD) modulation with hardware-accelerated SmartSense tuning, enabling robust touch detection under moisture and EMI. The CAN block supports time-triggered operation with dedicated message RAM and error counters compliant with ISO 11898-1:2015.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0+, 48 MHz max - enables deterministic real-time control with Thumb-2 instruction set and NVIC interrupt handling. |
| Flash / SRAM | 128 KB flash with Read Accelerator; 16 KB SRAM - supports complex automotive firmware with fast code execution and data buffering. |
| Operating Voltage | 1.71 V to 5.5 V - allows direct interface with 3.3 V and 5 V automotive subsystems without level-shifting. |
| Deep Sleep Current | 2.5 µA digital system current - enables always-on wake-on-touch or wake-on-CAN functionality in low-power vehicle modules. |
| CAPSENSE™ SNR | > 5:1 signal-to-noise ratio - ensures reliable button/slider detection under condensation, glove use, or EMI-rich cabin environments. |
| CAN Interface | CAN 2.0B with TTCAN support - provides deterministic message scheduling and synchronization for safety-critical body control networks. |
| GPIO Count | 54 programmable pins - supports multi-function routing for touch, analog sensing, PWM lighting control, and LIN/CAN coexistence. |
Pinout & Package
Package: 48-pin QFN (7 mm × 7 mm, 0.5 mm pitch), RoHS-compliant, wettable flank option available.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDIO0–VDDIO3 | I/O power supply domains | Independent 1.71–5.5 V supplies per port group - enables mixed-voltage interfacing (e.g., 3.3 V logic + 5 V analog sensors). |
| P0.0–P9.7 | Programmable GPIO | 54 total pins; each supports CAPSENSE™, analog input/output, digital logic, or SCB/CAN functions via hardware routing matrix. |
| XTAL_IN / XTAL_OUT | External crystal oscillator input/output | Supports 4–33 MHz ECO for precise timing; required for CAN bit-rate accuracy and USB-free clock recovery. |
| CAN_TX / CAN_RX | Dedicated CAN transceiver interface | Direct connection to external CAN PHY; internal termination and filtering reduce BOM count and PCB area. |
| WAKEUP[0–3] | Deep Sleep wake sources | Four independent wake inputs - enables selective wake from CAPSENSE™, GPIO, CAN activity, or timer events without full CPU boot. |
Key Features
| Feature | Design Value |
|---|---|
| SmartSense auto-tuning | Hardware-accelerated CAPSENSE™ calibration eliminates manual firmware tuning and maintains SNR across temperature/humidity drift. |
| Reconfigurable SCBs | Five serial blocks dynamically switch between I²C/SPI/UART/LIN slave modes at runtime - reduces peripheral count and simplifies protocol migration. |
| TTCAN support | Time-triggered CAN scheduling with guaranteed latency and synchronized message transmission - meets ASAM MCD-2 MC timing requirements. |
| Deep Sleep analog retention | Opamps, comparators, and SAR ADC remain active during 2.5 µA Deep Sleep - enables continuous sensor monitoring without CPU intervention. |
| Programmable drive strength | Configurable GPIO output drive (2–25 mA) and slew rate per pin - optimizes EMI, rise/fall times, and noise immunity for LED drivers or relay controls. |
Applications
| Automotive Door Module | Smart HVAC Control Panel |
|---|---|
Use Scenario: Multi-button capacitive touch interface with backlight dimming and window lock status feedback. IC Role / Device Role / Timing Role: Main MCU executing touch scan, PWM lighting control, LIN slave communication, and CAN gateway logic.

Use Value: >5:1 SNR ensures reliable slider tracking under condensation; Deep Sleep mode extends battery backup runtime to >72 hours. |
| Body Control Unit (BCU) | Seat Position Memory System |
Use Scenario: Centralized control of door locks, mirrors, lights, and interior lighting with CAN network coordination. IC Role / Device Role / Timing Role: CAN 2.0B + TTCAN node managing scheduled diagnostics, firmware updates, and actuator command arbitration. Use Value: Time-triggered messaging guarantees <100 µs jitter for synchronized mirror fold/unfold sequences across multiple ECUs. | Use Scenario: Motorized seat position storage and recall using potentiometer feedback and memory seat buttons. IC Role / Device Role / Timing Role: Analog front-end (opamp + SAR ADC) for precision pot reading, TCPWM for motor drive, and EEPROM-emulated flash for seat profile storage. Use Value: On-die opamp buffering eliminates external signal conditioning; 12-bit ADC resolution achieves ±0.5° seat angle accuracy. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP S32K144 | ARM Cortex-M4F core, 112 MHz; no integrated CAPSENSE™; requires external touch controller. | Better floating-point performance for motor control algorithms; lacks native capacitive sensing. | Select when high-speed math or AUTOSAR Classic compliance is prioritized over touch integration. |
| Renesas RL78/F14 | 16-bit RL78 core, 32 MHz; built-in touch I/O but no sigma-delta CSD; lower SNR (~3:1) and no SmartSense. | Lower cost for basic touch panels; insufficient for water-tolerant or high-EMI cabin applications. | Select for entry-level interior switches where moisture resistance and SNR are non-critical. |
Compared with S32K144 and RL78/F14, CY8C4147AZS-S285 uniquely delivers certified automotive touch sensing, TTCAN, and sub-3 µA Deep Sleep in a single die - eliminating external components while meeting Grade-S thermal and AEC-Q100 requirements.

FAQ
Does CY8C4147AZS-S285 support AUTOSAR?
No, CY8C4147AZS-S285 does not natively support AUTOSAR Classic or Adaptive stacks. It is designed for bare-metal or RTOS-based automotive applications (e.g., FreeRTOS, Micrium µC/OS). AUTOSAR compatibility requires external middleware integration and is not validated by Infineon for this device.
What is the maximum operating temperature for Grade-S qualification?
The CY8C4147AZS-S285 is qualified to AEC-Q100 Grade-S, with guaranteed operation from –40°C to +105°C ambient temperature. This rating covers junction temperatures up to +125°C under specified power dissipation and PCB thermal design conditions.
Can the internal opamps drive capacitive loads directly?
Yes, the two continuous-time opamps support programmable drive strength and can directly drive capacitive loads up to 100 pF in buffer mode. For larger loads (>100 pF), external isolation resistors are recommended to maintain phase margin and prevent oscillation.
Is CAN FD supported on this device?
No, CY8C4147AZS-S285 implements CAN 2.0B only, with TTCAN extensions. It does not support CAN FD data rates, frame formats, or CRC enhancements. CAN FD capability requires PSoC™ 6 or external CAN FD controllers.
