Infineon Technologies CY8C4149LDAS563XQLA1

Overview

CY8C4149LDAS563XQLA1 from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-grade 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), and multi-sense capacitive sensing (MSC) with >5:1 SNR. It supports CAPSENSE™, LCD segment drive, five reconfigurable SCBs (I²C/SPI/UART/LIN), and hardware cryptography (AES/SHA/TRNG).

For engineers reviewing the CY8C4149LDAS563XQLA1 datasheet, CY8C4149LDAS563XQLA1 pinout, CY8C4149LDAS563XQLA1 application, or CY8C4149LDAS563XQLA1 equivalent, key selection considerations include CAN FD timing compliance, Deep Sleep current (2.5 µA), MSC water-tolerance capability, programmable analog opamp modes, and GPIO flexibility across 84 pins in 100-pin TQFP.

Technical Context

The device implements a single-layer AHB-Lite interconnect linking the Cortex-M0+ core, DMA engine, and peripherals including eight TCPWM blocks with quadrature decode and comparator-triggered kill signals for motor control safety. Its analog subsystem integrates two CTBm opamps (operable in Deep Sleep), a 12-bit 1-Msps SAR ADC with temperature sensor, and two low-power comparators - all accessible via any GPIO.

Digital reconfigurability is enabled by Smart I/O logic blocks and five Serial Communication Blocks (SCBs) supporting runtime mode switching between I²C, SPI, UART, or LIN Slave. The CAN FD block operates at up to 5 Mbps with dedicated message RAM and protocol error handling, while the Crypto block accelerates AES-128/256, SHA-1/256, CRC, and TRNG functions.

FAQ

What is the maximum operating frequency of the Arm® Cortex®-M0+ core in CY8C4149LDAS563XQLA1?

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 fully supported across all operating voltage ranges (1.71–5.5 V) and temperature grades, including Grade-S (–40°C to +105°C).

Does CY8C4149LDAS563XQLA1 support CAN FD with bit-rate switching?

Yes, the integrated CAN FD block supports bit-rate switching - nominal arbitration phase up to 1 Mbps and data phase up to 5 Mbps - with dedicated message RAM, hardware filtering, and protocol error handling per ISO 11898-1:2015. It requires no external transceiver for physical layer compliance when paired with a standard CAN FD transceiver.

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

Up to 84 GPIO pins are available for CAPSENSE™ sensing, with the Multi-Sense Converter (MSC) block supporting up to 8 simultaneous sense channels (MSC_CH0–MSC_CH7) in self-capacitance mode or 4 pairs in mutual-capacitance mode. All GPIOs are software-mapped to MSC inputs without hardware routing restrictions.

Is the 12-bit SAR ADC capable of differential measurements and internal temperature sensing?

Yes, the 12-bit SAR ADC supports both differential and single-ended input modes with programmable gain and channel sequencing. It includes a built-in temperature sensor calibrated against the die temperature, delivering ±2.5°C accuracy over the full Grade-S range (–40°C to +105°C) without external components.
