Product details
Overview
CY8C4147AZE-S255 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 touch-sensing with SmartSense auto-tuning. It includes five reconfigurable serial communication blocks (I²C/SPI/UART/LIN), a CAN 2.0B controller with TTCAN support, and eight 16-bit TCPWMs-enabling motor control and human-machine interface functions in automotive body electronics.
For engineers reviewing the CY8C4147AZE-S255 datasheet, CY8C4147AZE-S255 pinout, CY8C4147AZE-S255 application, or CY8C4147AZE-S255 equivalent, key selection criteria include its AEC-Q100 Grade-S qualification, on-chip CAPSENSE™ SNR >5:1, CAN 2.0B + TTCAN timing compliance, Deep Sleep current of 2.5 µA, and programmable analog/digital routing for mixed-signal system integration.
Technical Context
This device implements a tightly coupled mixed-signal SoC architecture where the Arm® Cortex®-M0+ core executes firmware while dedicated hardware blocks handle real-time analog acquisition (12-bit 1-Msps SAR ADC), sigma-delta capacitive sensing (CSD), and deterministic CAN messaging. Its clock system integrates PLL, ECO (4–33 MHz), WCO (32 kHz), IMO (±2%), and ILO for multi-domain timing control.
The programmable digital fabric includes Smart I/O blocks for Boolean logic on GPIOs and TCPWMs supporting center-aligned PWM, quadrature decoding, and comparator-triggered kill signals-critical for motor drive safety. Analog resources feature two opamps operable in Deep Sleep, dual IDACs for self-capacitance sensing, and low-power comparators enabling always-on wake-up detection.

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable mixed-signal MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4147AZI-S455 | Same die, AEC-Q100 Grade-E (–40°C to +125°C), 48-pin QFN package | Targeted for under-hood applications requiring higher junction temperature tolerance | Select when operating ambient exceeds +105°C or full Grade-E qualification is mandated by OEM spec. |
| CY8C4146AZE-S255 | Same package and grade, but with 64 KB flash / 8 KB SRAM (reduced memory) | Suitable for cost-sensitive designs with simpler firmware and no bootloader or OTA requirements | Choose when application firmware size remains below 56 KB and no future feature expansion is planned. |
Compared with CY8C4147AZE-S255, the Grade-E variant offers extended thermal range at identical peripheral capability, while the 64 KB flash version trades memory headroom for lower unit cost-neither is pin-compatible with non-4100S Plus families due to routing and register map differences.

FAQ
What is the maximum operating frequency of the Arm® Cortex®-M0+ core in CY8C4147AZE-S255?
The CY8C4147AZE-S255 operates its Arm® Cortex®-M0+ CPU at up to 48 MHz, achieved via internal PLL multiplication of the IMO or external crystal oscillator input. This frequency is fully supported across the entire Grade-S temperature range (–40°C to +105°C) and enables real-time execution of CAPSENSE™ algorithms, CAN protocol stacks, and motor control loops without throttling.
Does CY8C4147AZE-S255 support hardware-based capacitive touch sensing without external components?
Yes. The device integrates a dedicated capacitance-sigma-delta (CSD) block with built-in IDACs, modulators, and digital filtering that performs self-capacitance and mutual-capacitance sensing directly on any GPIO pin. SmartSense auto-tuning adjusts sensing parameters dynamically, eliminating need for external RC networks or calibration firmware.
Can the CAN peripheral operate in time-triggered mode without external timing references?
Yes. The integrated CAN 2.0B block supports Time-Triggered CAN (TTCAN) using the internal 48-MHz clock domain synchronized to the ECO or WCO. TTCAN message scheduling and time-stamping are handled entirely in hardware, requiring no external time-source or software intervention for deterministic frame transmission.
What debug and programming interfaces are supported during development?
CY8C4147AZE-S255 supports SWD (Serial Wire Debug) via dedicated debug pins and is compatible with Infineon's MiniProg3 and KitProg3 programmers. It also supports PSoC™ Creator and ModusToolbox™ IDE workflows, including flash programming, real-time variable watch, and hardware breakpoint debugging without requiring additional JTAG adapters.
