Infineon Technologies CY8C4149LDSS593XQLA1

Overview

CY8C4149LDSS593XQLA1 from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-qualified PSoC™ 4100S Max microcontroller based on Arm® Cortex®-M0+ CPU, featuring 48 MHz operation, 384 KB flash, 32 KB SRAM, CAN FD up to 5 Mbps, and integrated CAPSENSE™ with SmartSense auto-tuning. It targets body control modules and in-cabin HMI systems requiring robust capacitive touch, motor control PWM, and secure communication.

For engineers reviewing the CY8C4149LDSS593XQLA1 datasheet, CY8C4149LDSS593XQLA1 pinout, CY8C4149LDSS593XQLA1 application, or CY8C4149LDSS593XQLA1 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 reconfigurable Serial Communication Blocks (SCBs), and 8 TCPWM blocks supporting center-aligned PWM and quadrature decoding for motor position sensing. Its analog subsystem includes two opamps with Deep Sleep operation, a 12-bit SAR ADC with temperature sensor, and dual low-power comparators - all accessible via any of up to 84 GPIOs.

The programmable architecture enables hardware-level logic synthesis via Smart I/O and Boolean operations on port signals, while the CAN FD block implements ISO 11898-1:2015 compliant transceiver-less protocol handling at up to 5 Mbps with flexible bit-rate switching and CRC-17 error detection.

FAQ

What is the maximum operating frequency of the Arm® Cortex®-M0+ core in CY8C4149LDSS593XQLA1?

The Arm® Cortex®-M0+ core operates at a maximum frequency of 48 MHz, achieved via internal PLL multiplication from the 4–33 MHz external crystal oscillator (ECO) or the ±2% internal main oscillator (IMO). This frequency is fully supported across all AEC-Q100 Grade-S operating conditions (–40°C to +105°C) and enables deterministic real-time execution of automotive control tasks with sub-microsecond interrupt latency.

Does CY8C4149LDSS593XQLA1 support CAN FD with bit-rate switching?

Yes, the integrated CAN FD block complies with ISO 11898-1:2015 and supports bit-rate switching - allowing arbitration phase at 1 Mbps and data phase up to 5 Mbps. It includes dedicated message RAM, hardware filtering, and CRC-17 calculation, eliminating need for external CAN FD transceivers in standard 12 V automotive networks.

How many GPIO pins can be used simultaneously for CAPSENSE™ electrodes?

All 84 GPIO pins are individually configurable as CAPSENSE™ electrodes, with hardware-supported mutual-capacitance scanning across up to 64 electrodes per MSC block. The device contains two MSC blocks, enabling simultaneous multi-touch gesture recognition on separate zones (e.g., center console + steering wheel) without CPU intervention.

Is the 12-bit SAR ADC calibrated across temperature and voltage variations?

Yes, the SAR ADC includes factory-trimmed offset/gain calibration stored in flash, and supports runtime self-calibration triggered by software or hardware events. It maintains ±1 LSB INL and DNL across –40°C to +105°C and 1.71–5.5 V VDDA, with built-in temperature sensor referenced to the same analog reference for accurate thermal compensation.
