Infineon Technologies CY8C4147LDES553XQLA1

Overview

CY8C4147LDES553XQLA1 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, integrated CAN FD (up to 5 Mbps), 12-bit 1-Msps SAR ADC, dual opamps with Deep Sleep operation, and multi-sense capacitive sensing (MSC) with >5:1 SNR for touch interfaces in harsh environments.

For engineers reviewing the CY8C4147LDES553XQLA1 datasheet, CY8C4147LDES553XQLA1 pinout, CY8C4147LDES553XQLA1 application, or CY8C4147LDES553XQLA1 equivalent, this device supports reconfigurable analog/digital logic, hardware crypto acceleration (AES/SHA/TRNG), TCPWM-based motor control kill signals, and five runtime-reconfigurable SCBs for I²C/SPI/UART/LIN - critical for automotive body control, infotainment HMI, and ADAS sensor interface design.

Technical Context

The CY8C4147LDES553XQLA1 implements a single-layer AHB-Lite interconnect linking its Cortex-M0+ core, memory subsystem (384 KB flash + 32 KB SRAM), and heterogeneous peripherals including CAN FD, MSC, CTBm analog blocks, and five SCBs. Its clock system integrates ECO (4–33 MHz) with PLL, WCO, IMO (±2%), and ILO (40 kHz) for precise timing across sleep/wake transitions.

It supports concurrent low-power operation: Deep Sleep mode draws 2.5 µA digital current while maintaining active analog functions (opamps, comparators, MSC), and all 84 GPIOs are programmable for CAPSENSE™, analog input, or digital I/O with configurable drive strength and slew rate - enabling unified signal acquisition and actuation in space-constrained automotive modules.

FAQ

What is the maximum operating frequency of the Arm® Cortex®-M0+ core in CY8C4147LDES553XQLA1?

The Arm® Cortex®-M0+ core operates at a maximum frequency of 48 MHz, achieved via internal PLL locked to an external crystal oscillator (ECO) or the ±2% internal main oscillator (IMO). This frequency is fully supported across the full Grade-S temperature range (–40°C to +105°C) and enables deterministic real-time execution of automotive control algorithms with sub-microsecond interrupt latency.

Does CY8C4147LDES553XQLA1 support CAN FD in both transmitter and receiver modes?

Yes, the integrated CAN FD block supports full-duplex operation at data rates up to 5 Mbps, including bit-rate switching between nominal and data phases. It implements ISO 11898-1 compliant protocol handling, message filtering, and FIFO-based transmit/receive buffers - requiring only an external CAN transceiver for physical layer connection.

How many pins support CAPSENSE™ functionality, and what is the minimum recommended trace length?

All 84 GPIO pins support CAPSENSE™ via the Multi-Sense Converter (MSC) block. For optimal SNR, Infineon recommends keeping sensor trace lengths under 10 cm with 5–10 mil width and solid ground plane beneath; longer traces require guard ring implementation and layout tuning per AN91820 guidelines.

Is hardware cryptographic acceleration available in Deep Sleep mode?

No - the AES/SHA/TRNG/CRC crypto engine is disabled in Deep Sleep mode to minimize leakage current. However, the device retains SRAM content and can wake rapidly (<1 µs) upon interrupt to execute cryptographic operations in Active mode, supporting secure key derivation and signature verification in low-duty-cycle applications.
