Product details
Overview
CY8C4147LDES543XQLA1 from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-qualified PSoC™ 4100S Max microcontroller featuring a 48-MHz Arm® Cortex®-M0+ CPU, 384 KB flash, 32 KB SRAM, CAN FD up to 5 Mbps, and integrated CAPSENSE™ with SmartSense auto-tuning. It supports capacitive touch sensing in harsh environments and drives motor control via eight 16-bit TCPWM blocks with comparator-triggered kill signals.
For engineers reviewing the CY8C4147LDES543XQLA1 datasheet, CY8C4147LDES543XQLA1 pinout, CY8C4147LDES543XQLA1 application, or CY8C4147LDES543XQLA1 equivalent, key selection criteria include CAN FD timing compliance, Deep Sleep current (2.5 µA), SAR ADC resolution (12-bit, 1-Msps), MSC SNR (>5:1), and GPIO reconfigurability across analog/digital/CAPSENSE™ functions.
Technical Context
The device integrates a single-layer AHB-Lite interconnect linking the Cortex-M0+ core, 5 configurable Serial Communication Blocks (SCBs), and a dedicated CAN FD controller with bit-rate switching support up to 5 Mbps. Its analog subsystem includes two opamps with Deep Sleep operation, a 12-bit SAR ADC with temperature sensor and channel sequencer, and two low-power comparators - all accessible via any of up to 84 GPIOs.
Digital flexibility is enabled by programmable Smart I/O logic, eight TCPWM blocks supporting center-aligned PWM and quadrature decoding, and hardware cryptography accelerators for AES, SHA, TRNG, and CRC. Clocking combines ECO+PLL (48 MHz), WCO (32 kHz), IMO (±2%), and ILO (40 kHz) sources with dynamic power mode transitions.
Key Specifications

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SPC560P50L5 | Power Architecture e200z0h core, 64 MHz, 512 KB flash, no integrated CAPSENSE™ or Smart I/O | Lacks hardware-accelerated capacitive sensing and GPIO reconfigurability - requires external touch controller | Prefer when legacy Power Architecture toolchain or ASIL-D certification path is required |
| TC375LPD | TriCore™ AURIX™ TC3xx, 300 MHz, 4 MB flash, 2 MB RAM, dual-core lockstep, integrated Ethernet | Higher ASIL-D capability and safety mechanisms but larger footprint, higher power, and no native CAPSENSE™ | Choose for domain controller-level integration where CAN FD + Ethernet coexistence is mandatory |
Compared with SPC560P50L5 and TC375LPD, CY8C4147LDES543XQLA1 delivers optimal balance of capacitive sensing integration, low-power operation (2.5 µA Deep Sleep), and AEC-Q100 Grade-S qualification - making it ideal for cost-sensitive, space-constrained automotive human-machine interface and body electronics.

FAQ
What is the maximum operating temperature range for CY8C4147LDES543XQLA1?
This part is qualified to AEC-Q100 Grade-S, supporting continuous operation from –40°C to +105°C. The silicon and packaging are validated for thermal cycling and long-term reliability under these conditions, with full electrical specifications guaranteed across the range. No derating is required up to +105°C ambient.
Does CY8C4147LDES543XQLA1 support CAN FD with bit-rate switching?
Yes, the integrated CAN FD block supports bit-rate switching per ISO 11898-1:2015, enabling arbitration phase at 1 Mbps and data phase up to 5 Mbps. Hardware handles protocol framing, error detection, and automatic retransmission without CPU intervention.
Can all 84 GPIOs be used simultaneously for CAPSENSE™ sensing?
No - while any GPIO can be assigned to CAPSENSE™, the Multi-Sense Converter (MSC) block supports up to 32 simultaneous sensing channels. Channel count depends on scan time, resolution, and SNR targets; full 84-pin utilization requires time-multiplexed scanning.
Is ModusToolbox™ required for development with this device?
ModusToolbox™ is Infineon's recommended IDE and provides full PDL support, CAPSENSE™ Tuner, and CAN FD configuration tools. However, the device is Arm®-compliant and can be programmed using GCC-based toolchains, OpenOCD, and custom HALs - no vendor lock-in is enforced.
