Product details
Overview
CY8C4147AZE-S445T 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 >5:1 SNR. It includes a CAN 2.0B block with TTCAN support, five reconfigurable SCBs (I²C/SPI/UART/LIN), and eight TCPWM blocks-used in motor control, touch HMI, and body electronics systems.
For engineers reviewing the CY8C4147AZE-S445T datasheet, CY8C4147AZE-S445T pinout, CY8C4147AZE-S445T application, or CY8C4147AZE-S445T equivalent, key selection criteria include AEC-Q100 Grade-S qualification, on-chip CAPSENSE™ with SmartSense auto-tuning, CAN 2.0B + TTCAN timing compliance, Deep Sleep current of 2.5 µA, and GPIO flexibility across 54 pins with programmable drive strength and slew rate.
Technical Context
This device implements a tightly integrated mixed-signal SoC architecture where the Arm® Cortex®-M0+ core coordinates programmable analog (CTB opamps, 12-bit SAR ADC, IDACs), digital (TCPWM, SCB, CAN), and CAPSENSE™ sigma-delta sensing blocks via shared interconnect and DMA. Its clock system combines ECO (4–33 MHz), WCO (32 kHz), IMO (±2%), and ILO for precise timing across sleep/wake transitions.
The CAN block supports time-triggered communication with hardware timestamping and message filtering, while CAPSENSE™ uses dedicated CSD hardware with automatic baseline calibration and water-tolerance algorithms-enabling robust touch interfaces without external components in harsh automotive environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP S32K144HAT0MLHT | ARM Cortex-M4F core, 112 MHz; includes Ethernet MAC and FlexCAN FD; no integrated CAPSENSE™ | Targets higher-performance powertrain and ADAS edge nodes requiring floating-point math and CAN FD bandwidth | Select when CAN FD, Ethernet, or DSP-intensive firmware is required; add external touch controller for capacitive UI. |
| Renesas RL78/F14 | 16-bit RL78 core, 32 MHz; AEC-Q100 Grade-2 (–40°C to +105°C); no CAN FD or CAPSENSE™ | Cost-sensitive body electronics with basic CAN 2.0B and minimal analog needs | Choose for legacy toolchain continuity and lower unit cost where touch UI and TTCAN are not required. |
Compared with S32K144HAT0MLHT and RL78/F14, CY8C4147AZE-S445T uniquely integrates CAPSENSE™, TTCAN, and Deep Sleep analog retention in a single AEC-Q100 Grade-S package-making it optimal for touch-enabled body controllers where mixed-signal consolidation and deterministic timing outweigh raw compute throughput.

FAQ
Does CY8C4147AZE-S445T support CAN FD?
No. This device implements a CAN 2.0B controller with optional time-triggered CAN (TTCAN) functionality but does not support CAN FD data rates or extended frame formats. For CAN FD, consider Infineon's AURIX™ TC3xx series or NXP's S32K3xx family.
What development tools are officially supported for this part?
Infineon officially supports ModusToolbox™ (v3.1+) and PSoC™ Creator (v4.4) for firmware development, along with CY8CKIT-149 prototyping kit and MiniProg3 programmer/debugger. Both IDEs provide full peripheral configuration, CAPSENSE™ tuning, and CAN register-level access.
Is the 12-bit SAR ADC capable of simultaneous sampling?
No. The 12-bit SAR ADC has a single conversion engine with channel sequencer and signal averaging, but lacks dual or interleaved sampling hardware. Simultaneous sampling requires external synchronized ADCs or devices like Infineon's XMC7000 series with dual-core ADC support.
Can CAPSENSE™ operate during Deep Sleep mode?
Yes. CAPSENSE™ CSD hardware remains active in Deep Sleep mode with 2.5 µA system current, enabling wake-on-touch functionality. SmartSense auto-tuning runs during wake cycles, and baseline tracking continues in low-power mode using internal comparators and IDACs.
