Product details
Overview
CY8C4147AZE-S285 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), eight 16-bit TCPWM units, a CAN 2.0B controller with TTCAN support, and programmable analog blocks including two opamps and a 12-bit 1-Msps SAR ADC. It targets automotive body electronics requiring robust touch interfaces and real-time control.
For engineers reviewing the CY8C4147AZE-S285 datasheet, CY8C4147AZE-S285 pinout, CY8C4147AZE-S285 application, or CY8C4147AZE-S285 equivalent, key selection criteria include AEC-Q100 Grade-S qualification, on-chip CAPSENSE™ SNR >5:1 with water tolerance, CAN 2.0B + TTCAN compliance, Deep Sleep current of 2.5 µA, and GPIO flexibility across 54 pins with programmable drive strength and slew rate.
Technical Context
The CY8C4147AZE-S285 integrates a fixed-function CAN 2.0B controller supporting time-triggered communication (TTCAN) and message filtering, alongside five SCBs that can be independently configured as I²C, SPI, UART, or LIN slave - enabling mixed-protocol connectivity in automotive domain controllers. Its analog subsystem includes two continuous-time opamps with Deep Sleep operation, a 12-bit SAR ADC with channel sequencer and signal averaging, and a dedicated capacitance-sensing block for sigma-delta (CSD) touch measurement.
Digital resources comprise eight TCPWM blocks supporting center-aligned PWM, quadrature decoding, and comparator-triggered kill signals for motor safety; plus Smart I/O logic for Boolean port-level operations without CPU intervention. Clocking includes a 4–33 MHz ECO, PLL for 48-MHz core clock, and multiple low-power oscillators (WCO, ILO, IMO) enabling precise timing and ultra-low-power wake-up sequences.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4147AZI-S485 | AEC-Q100 Grade-E (–40°C to +125°C), identical peripherals and pinout, but higher temperature rating and slightly higher max operating voltage (5.5 V vs. 5.5 V same). | Suitable for under-hood applications (e.g., engine bay sensors) where ambient exceeds +105°C. | Select when extended junction temperature range is required; otherwise, S285 offers cost and thermal margin optimization for cabin modules. |
| SPC560B50L5 | Power Architecture e200z0h core, 64 MHz, 512 KB flash, 48 KB RAM, no integrated CAPSENSE™, requires external touch controller. | Targeted at powertrain and transmission control where analog sensing is secondary to deterministic interrupt latency. | Choose only if legacy Power Architecture toolchain compatibility or ASIL-B functional safety certification is mandatory; lacks native touch capability. |
Compared with CY8C4147AZE-S285, the S485 variant adds +20°C junction margin at identical cost structure, while the SPC560B50L5 trades integrated CAPSENSE™ and flexible analog for higher flash density and certified ASIL-B support - making it unsuitable for touch-centric cabin ECUs without added components.

FAQ
Is CY8C4147AZE-S285 qualified for automotive applications?
Yes. CY8C4147AZE-S285 is AEC-Q100 qualified to Grade-S (–40°C to +105°C), with full qualification test reports available from Infineon. It meets automotive reliability standards for HTOL, TC, UHAST, and ESD (HBM ≥2 kV, CDM ≥1 kV), and is manufactured in IATF 16949-certified facilities.
Does this device support CAN FD?
No. CY8C4147AZE-S285 implements CAN 2.0B with TTCAN extensions only. It does not support CAN FD data rates or frame formats. For CAN FD, consider Infineon's TRAVEO™ T2G or AURIX™ families, which provide native CAN FD controllers with ISO 11898-1:2015 compliance.
Can CAPSENSE™ operate during Deep Sleep mode?
Yes. The CSD block and associated opamps can remain active in Deep Sleep mode with total system current as low as 2.5 µA. This enables capacitive wake-up events (e.g., button press) without full CPU wake-up, preserving battery life in always-on automotive modules.
What development tools are supported?
CY8C4147AZE-S285 is fully supported by ModusToolbox™ (v3.1+) and legacy PSoC™ Creator (v4.4). Hardware evaluation is enabled via CY8CKIT-149 (PSoC™ 4100S Plus prototyping kit) and CY8CKIT-041-41XX (CAPSENSE™ Pioneer Kit), both including MiniProg3 debug/programming interface and Arduino-compatible headers.
