Product details
Overview
CY8C4147AZE-S455T 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-S455T datasheet, CY8C4147AZE-S455T pinout, CY8C4147AZE-S455T application, or CY8C4147AZE-S455T 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 GPIO flexibility across 54 pins with programmable drive strength and slew rate.
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 low-power comparators, and two IDACs-are fully programmable and routed via automatic interconnect fabric. Its CAN block supports time-triggered operation with hardware synchronization to system clocks and external triggers.
The TCPWM subsystem provides quadrature decoding, comparator-triggered kill signals for motor safety, and center-aligned/edge/pseudo-random PWM modes. Clocking includes a 4–33 MHz ECO, PLL-derived 48-MHz core clock, 32-kHz WCO, and ±2% IMO-enabling precise timing across automotive sensor, actuator, and communication functions.

FAQ
What is the maximum operating temperature for CY8C4147AZE-S455T?
The CY8C4147AZE-S455T is qualified to AEC-Q100 Grade-S, supporting continuous operation from –40°C to +105°C ambient temperature. This rating is verified per JEDEC JESD47 and includes thermal cycling, high-temperature operating life, and storage tests-making it suitable for under-hood and cabin applications where thermal stress exceeds standard commercial grades.
Does this device support CAN FD or only classical CAN?
The CY8C4147AZE-S455T integrates a CAN 2.0B controller with Time-Triggered CAN (TTCAN) support but does not implement CAN FD physical layer or protocol extensions. It supports bit rates up to 1 Mbps in classical CAN mode and provides hardware timestamping, synchronization, and schedule table execution for deterministic network behavior-aligned with AUTOSAR-compliant CAN stacks.
Can CAPSENSE™ operate during Deep Sleep mode?
Yes-CAPSENSE™ CSD sensing can run autonomously in Deep Sleep mode using the internal low-power oscillator (ILO) and dedicated hardware sequencer. The device draws only 2.5 µA total system current while continuously scanning up to 32 electrodes, with wake-up interrupts generated upon touch detection-enabling zero-power HMI standby in automotive infotainment and control panels.
Is ModusToolbox™ required, or can PSoC™ Creator still be used?
Both tools are supported: PSoC™ Creator remains fully functional for legacy and new designs targeting CY8C4147AZE-S455T, offering schematic-based hardware configuration and API-driven firmware development. ModusToolbox™ is recommended for new projects due to its IDE-neutral workflow, GitHub-hosted PDL libraries, and enhanced CI/CD integration-but PSoC™ Creator continues to receive updates and technical support from Infineon.
