Product details
Overview
CY8C4149LDAS573XQLA1 from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-grade PSoC™ 4100S Max microcontroller based on Arm® Cortex®-M0+ CPU, featuring 48 MHz operation, 384 KB flash, 32 KB SRAM, integrated CAN FD (up to 5 Mbps), and multi-sense capacitive sensing (MSC) with >5:1 SNR for touch interfaces in harsh environments.
For engineers reviewing the CY8C4149LDAS573XQLA1 datasheet, CY8C4149LDAS573XQLA1 pinout, CY8C4149LDAS573XQLA1 application, or CY8C4149LDAS573XQLA1 equivalent, this device supports reconfigurable analog/digital blocks, Deep Sleep mode at 2.5 µA, hardware crypto acceleration (AES/SHA/TRNG), and five runtime-reconfigurable SCBs for I²C/SPI/UART/LIN - critical for automotive body control, infotainment HMI, and motor control timing systems.
Technical Context
The CY8C4149LDAS573XQLA1 integrates a single-layer AHB-Lite interconnect linking its Cortex-M0+ core, 8× TCPWM blocks (supporting center-aligned PWM and quadrature decoding), and dual opamp CTBm blocks capable of ADC input buffering and Deep Sleep operation. Its clock system combines ECO (4–33 MHz), PLL (48 MHz output), WCO (32 kHz), and ±2% IMO for flexible timing across sleep/wake transitions.
Analog subsystem includes a 12-bit 1-Msps SAR ADC with temperature sensor, two low-power comparators active in Deep Sleep, and MSC block enabling CAPSENSE™ with SmartSense auto-tuning and water tolerance. Digital flexibility is extended via programmable Smart I/O and five SCBs supporting concurrent I²C, SPI, UART, and LIN Slave protocols.

FAQ
What is the maximum operating temperature range for CY8C4149LDAS573XQLA1?
CY8C4149LDAS573XQLA1 is qualified to AEC-Q100 Grade-S, supporting continuous operation from –40°C to +105°C ambient temperature. This rating is verified per test condition HTOL (High Temperature Operating Life) and TC (Temperature Cycling), ensuring reliability in under-hood and dashboard-mounted automotive applications.
Does CY8C4149LDAS573XQLA1 support CAN FD with ISO 11898-1 physical layer compliance?
No - CY8C4149LDAS573XQLA1 contains a CAN FD protocol controller only. It requires an external CAN FD transceiver (e.g., Infineon TJA1044, NXP TJA1057) to achieve ISO 11898-1 physical layer compliance and bus termination. The device provides dedicated CAN_TX/CAN_RX pins with slew-rate control for clean signal integrity.
Can the MSC block perform mutual-capacitance scanning without host CPU intervention?
Yes - the Multi-Sense Converter (MSC) block executes full mutual-capacitance scan sequences autonomously using hardware sequencers and DMA. It supports up to 64 electrodes, stores raw counts in SRAM, and triggers interrupts upon completion - enabling low-CPU-overhead touch detection during active or Deep Sleep modes.
Is ModusToolbox™ required to configure the programmable analog blocks?
No - while ModusToolbox™ provides graphical configuration and auto-generated PDL code for CTBm opamps and SAR ADC, all analog block registers are fully documented in the PSoC™ 4100S Max TRM (002-30041). Engineers may configure them directly via register writes or custom HAL drivers without ModusToolbox™ dependency.
