Product details
Overview
CY8C4147AZE-S455 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 modules - deployed in automotive body control modules for touch-enabled door handles and climate panels.
For engineers reviewing the CY8C4147AZE-S455 datasheet, CY8C4147AZE-S455 pinout, CY8C4147AZE-S455 application, or CY8C4147AZE-S455 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 strength and slew rate.
Technical Context
The device implements a tightly coupled mixed-signal architecture where the Arm® Cortex®-M0+ core executes firmware while programmable analog blocks (two opamps, 12-bit SAR ADC, two IDACs, two low-power comparators) and digital blocks (Smart I/O, TCPWM, SCBs) operate concurrently under hardware routing control. All analog peripherals remain functional in Deep Sleep mode at 2.5 µA system current.
Its clock system integrates a 4–33 MHz ECO, 32-kHz WCO, ±2% IMO, and 32-kHz ILO - feeding a PLL that locks to generate the precise 48-MHz CPU clock. The CAN block supports time-triggered operation with configurable bit timing and error counters, meeting ISO 11898-1 requirements for deterministic automotive networking.

FAQ
Does CY8C4147AZE-S455 support CAN FD?
No. CY8C4147AZE-S455 integrates a CAN 2.0B controller with Time-Triggered CAN (TTCAN) capability, compliant with ISO 11898-1:2015. It does not implement CAN FD frame format or bit-rate switching. For CAN FD, consider Infineon's AURIX™ TC3xx family or external CAN FD transceivers paired with this device's SCB in UART mode for bridging.
What development tools are officially supported?
Infineon officially supports ModusToolbox™ (v3.1+) and PSoC™ Creator v4.4 for CY8C4147AZE-S455. ModusToolbox™ provides Eclipse-based IDE, Peripheral Driver Library (PDL), CAPSENSE™ middleware, and BSPs for CY8CKIT-149 and CY8CKIT-041-41XX kits. PSoC™ Creator remains supported for legacy schematic-based design but is not updated beyond v4.4.
Is the 12-bit SAR ADC capable of simultaneous sampling?
No. The 12-bit SAR ADC has a single conversion core with a channel sequencer supporting up to 32 inputs, but it performs sequential conversions only. Simultaneous sampling is not supported. For multi-channel synchronized acquisition, external parallel-output ADCs or time-interleaved firmware sequencing with timestamping must be used.
How is AEC-Q100 Grade-S qualification verified for this part?
CY8C4147AZE-S455 is qualified to AEC-Q100 Grade-S (–40°C to +105°C) per Rev. G test plan, including stress tests for HTOL (1000 hrs @ 130°C), TCT (1000 cycles), ESD-HBM (±2 kV), and AC/DC parametric limits across temperature. Full qualification report is available under NDA from Infineon's Automotive Quality portal (document ID: Q002-20072-RevS).
