Product details
Overview
CY8C4147AZE-S295 from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-qualified 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), CAN 2.0B with TTCAN support, and eight 16-bit TCPWM blocks-used in motor control, touch HMI, and automotive body electronics.
For engineers reviewing the CY8C4147AZE-S295 datasheet, CY8C4147AZE-S295 pinout, CY8C4147AZE-S295 application, or CY8C4147AZE-S295 equivalent, key selection criteria include AEC-Q100 Grade-S qualification, on-die CAPSENSE™ SNR > 5:1, CAN 2.0B + TTCAN timing compliance, Deep Sleep current ≤ 2.5 µA, and GPIO flexibility across 54 pins with programmable drive modes.
Technical Context
This device implements a mixed-signal SoC architecture where analog and digital resources-including two continuous-time opamps, a 12-bit 1-Msps SAR ADC, dual IDACs, and low-power comparators-are routed via a programmable interconnect fabric. Its clock system integrates ECO (4–33 MHz), WCO (32 kHz), IMO (±2%), and ILO, with PLL enabling precise 48-MHz core operation.
The CAN block supports time-triggered communication (TTCAN) with dedicated message RAM and hardware timestamping, while CAPSENSE™ uses sigma-delta (CSD) modulation for robust water-tolerant touch detection. All analog peripherals remain functional in Deep Sleep mode, enabling ultra-low-power wake-on-touch or wake-on-CAN event operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0+, 48 MHz max - enables real-time deterministic execution of automotive control loops and sensor fusion algorithms |
| Flash / SRAM | 128 KB flash with Read Accelerator / 16 KB SRAM - supports secure bootloader, OTA updates, and dual-bank firmware storage |
| CAPSENSE™ SNR | > 5:1 signal-to-noise ratio - ensures reliable touch detection under wet conditions and EMI noise in automotive cabins |
| CAN Interface | CAN 2.0B with TTCAN support - provides deterministic, time-synchronized messaging for body control modules and gateway applications |
| Deep Sleep Current | 2.5 µA digital system current - enables battery-powered always-on touch wake-up without compromising vehicle battery life |
| GPIO Count | 54 programmable pins - each configurable as CAPSENSE™, analog input/output, or digital with slew-rate and drive-strength control |
| ADC Resolution | 12-bit SAR, 1-Msps - supports high-fidelity sensor acquisition (e.g., temperature, pressure, position) with hardware channel sequencing |
Pinout & Package
Package: 48-pin QFN (7 mm × 7 mm, 0.5 mm pitch), RoHS-compliant, thermally enhanced with exposed thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDIO0–VDDIO3 | I/O power supply rails | Independent 1.71–5.5 V domains per port group - enable mixed-voltage interface (e.g., 3.3 V MCU logic + 5 V analog sensors) |
| P0[0]–P0[7] | General-purpose GPIO bank | Supports CAPSENSE™ CSD, analog input, SCB UART/SPI/I²C, and TCPWM capture - all with programmable pull-up/down and interrupt-on-change |
| CAN_TX / CAN_RX | Dedicated CAN transceiver interface | Direct connection to external CAN PHY; internal termination and filtering reduce BOM count and PCB area |
| XTAL_IN / XTAL_OUT | External crystal oscillator inputs | Support 4–33 MHz ECO for precise clock source - required for CAN bit timing accuracy and TTCAN synchronization |
| VDDD / VSSD | Digital core supply/ground | 1.71–5.5 V core domain - powers CPU, flash, SRAM, and digital logic; decoupling critical for EMI immunity in automotive environments |
Key Features
| Feature | Design Value |
|---|---|
| SmartSense auto-tuning | Hardware-accelerated CAPSENSE™ calibration eliminates manual tuning and field recalibration - reduces development time and improves production yield |
| Programmable analog routing | Flexible interconnect between opamps, ADC, IDACs, and comparators - enables custom sensor signal chains without external components |
| TTCAN hardware timestamping | Dedicated 32-bit free-running timer synchronized to CAN bus clock - enables precise time-stamping of received messages for diagnostic logging and synchronization |
| Deep Sleep analog retention | Opamps, comparators, and CAPSENSE™ remain active at 2.5 µA - allows wake-on-touch or wake-on-CAN while preserving analog state |
| Reconfigurable SCBs | Five independent serial blocks each configurable as UART, SPI, I²C, or LIN slave - simplifies multi-protocol communication without additional ICs |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4147LQ-S295 | Same die, 64-pin QFN package, higher pin count (54 GPIO), no CAN block | Lacks CAN 2.0B/TTCAN - suitable only for non-networked touch/HMI or sensor nodes | Select when CAN is unnecessary and board layout requires larger footprint for routing or thermal relief |
| SPC560B50L5 | Power Architecture e200z0h core, 64 MHz, 512 KB flash, ASIL-B certified, no integrated CAPSENSE™ | Requires external touch controller and analog signal chain - increases BOM and layout complexity | Select when functional safety certification (ISO 26262 ASIL-B) is mandatory and touch is handled externally |
Compared with CY8C4147LQ-S295 and SPC560B50L5, CY8C4147AZE-S295 uniquely combines AEC-Q100 Grade-S qualification, on-die CAN+TTCAN, and production-ready CAPSENSE™-enabling single-chip solutions for cost-sensitive, space-constrained automotive HMI and body control designs.

FAQ
Does CY8C4147AZE-S295 support ISO 26262 functional safety requirements?
No, CY8C4147AZE-S295 is AEC-Q100 qualified (Grade-S) but not ISO 26262-certified. It lacks hardware safety mechanisms like lockstep cores or memory ECC required for ASIL-B/C. For safety-critical functions, it may serve as a monitoring or companion controller alongside a certified MCU, but cannot independently fulfill ASIL requirements.
What development tools are officially supported for this device?
Infineon officially supports ModusToolbox™ (v3.1+) and legacy PSoC™ Creator (v4.4) for CY8C4147AZE-S295. ModusToolbox™ provides Peripheral Driver Library (PDL), CAPSENSE™ middleware, and BSPs for CY8CKIT-149 and CY8CKIT-041-41XX kits. Debug requires KitProg3 or MiniProg3 with SWD interface.
Can the on-chip CAPSENSE™ replace mechanical buttons in automotive interior applications?
Yes-CY8C4147AZE-S295's CAPSENSE™ with CSD modulation and SmartSense achieves > 5:1 SNR and meets IEC 61000-4-6 immunity requirements for automotive interiors. It supports wet-finger operation, proximity wake-up, and gesture recognition, and has been validated in production HVAC and infotainment panels per OEM specifications.
Is external crystal required for CAN operation?
Yes-an external 4–33 MHz crystal (ECO) is mandatory for CAN bit timing accuracy and TTCAN synchronization. The internal IMO (±2%) does not meet CAN timing tolerance requirements; the ECO feeds the PLL to generate the precise 48-MHz system clock needed for CAN baud rate generation and timestamp consistency.
