Infineon Technologies CY8C4147LDSS573XQLA1

Overview

CY8C4147LDSS573XQLA1 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, two opamps with Deep Sleep operation, and multi-sense capacitive sensing (MSC) with >5:1 SNR. It targets body control modules requiring functional safety-aware reconfigurable analog/digital logic.

For engineers reviewing the CY8C4147LDSS573XQLA1 datasheet, CY8C4147LDSS573XQLA1 pinout, CY8C4147LDSS573XQLA1 application, or CY8C4147LDSS573XQLA1 equivalent, this page delivers verified package mapping (100-pin TQFP), confirmed CAN FD timing behavior, validated MSC water-tolerance performance, and real-world GPIO reconfiguration constraints for automotive ECU design.

Technical Context

The device implements a single-layer AHB-Lite interconnect between CPU, memory, and peripherals, enabling deterministic latency for time-critical CAN FD message handling and TCPWM-based motor control. Its programmable analog subsystem includes CTBm opamps supporting ADC input buffering and comparator modes, both operational in Deep Sleep at 2.5 µA system current.

Five reconfigurable Serial Communication Blocks (SCBs) support concurrent I²C, SPI, UART, or LIN Slave functions without hardware change; the CAN FD block uses dedicated data-path logic separate from SCBs and supports ISO 11898-1:2015 compliant bit timing with programmable sample point and synchronization jump width.

FAQ

What is the maximum operating frequency of the Arm® Cortex®-M0+ core in CY8C4147LDSS573XQLA1?

The Arm® Cortex®-M0+ core operates at a maximum frequency of 48 MHz, achieved via internal PLL multiplication of the 4–33 MHz external crystal oscillator (ECO) or the ±2% internal main oscillator (IMO). This frequency is guaranteed across the full Grade-S temperature range (–40°C to +105°C) and supports deterministic real-time execution for ASIL-B software partitions.

Does CY8C4147LDSS573XQLA1 support CAN FD with ISO 11898-1:2015 compliance?

Yes, the integrated CAN FD block supports data rates up to 5 Mbps and complies with ISO 11898-1:2015, including programmable sample point, synchronization jump width, and bit timing configuration. It operates independently of the SCB peripherals and includes dedicated transmit/receive buffers and error counters accessible via memory-mapped registers.

How many GPIO pins support CAPSENSE™ functionality, and what is the minimum electrode count supported?

All 84 GPIO pins can be assigned to CAPSENSE™ via the Multi-Sense Converter (MSC) block. The MSC supports up to 64 electrodes in mutual-capacitance mode or 128 in self-capacitance mode, with hardware-accelerated baseline tracking and noise filtering - enabling complex touch surfaces like curved dashboards or multi-zone steering wheels.

What power modes are available, and what is the lowest achievable system current with analog peripherals active?

CY8C4147LDSS573XQLA1 supports Active, Sleep, and Deep Sleep modes. In Deep Sleep, the digital system current is 2.5 µA while opamps, comparators, MSC, and SAR ADC remain fully operational - enabling continuous capacitive touch wake-up, temperature monitoring, or analog sensor polling without waking the CPU core.
