Product details
Overview
CY8C4149AZAS568XQLA1 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, CAN FD up to 5 Mbps, and integrated CAPSENSE™ with SmartSense auto-tuning. It serves as a reconfigurable system-on-chip for safety-critical body electronics and human-machine interface control.
For engineers reviewing the CY8C4149AZAS568XQLA1 datasheet, CY8C4149AZAS568XQLA1 pinout, CY8C4149AZAS568XQLA1 application, or CY8C4149AZAS568XQLA1 equivalent, key selection factors include CAN FD timing compliance, Deep Sleep current (2.5 µA), 12-bit SAR ADC performance (1 Msps, differential mode), GPIO flexibility (up to 84 pins, analog/digital/CAPSENSE™ configurable), and hardware crypto acceleration (AES/SHA/TRNG).
Technical Context
The device integrates a single-layer AHB-Lite interconnect linking Cortex-M0+ core, memory subsystem (384 KB flash + 32 KB SRAM), and heterogeneous peripherals including five reconfigurable Serial Communication Blocks (SCBs), eight TCPWM units with quadrature decode and kill-signal triggering, and dual opamps supporting Deep Sleep operation. Clocking includes ECO (4–33 MHz), PLL (48 MHz), WCO (32 kHz), and ±2% IMO.
Analog subsystem comprises a 12-bit SAR ADC with internal temperature sensor, two CTBm opamps with ADC input buffering, two low-power comparators, and a multi-sense converter (MSC) block delivering >5:1 SNR for capacitive sensing. Digital programmability extends to Smart I/O logic and Boolean operations on port signals.
Key Specifications

FAQ
What is the maximum operating temperature grade for CY8C4149AZAS568XQLA1?
CY8C4149AZAS568XQLA1 is qualified to AEC-Q100 Grade-S, supporting continuous operation from –40°C to +105°C ambient temperature. This rating is verified per JESD22-A108 and includes full functionality of all peripherals - including CAN FD, SAR ADC, and CAPSENSE™ - across the entire range.
Does CY8C4149AZAS568XQLA1 include a CAN FD physical layer?
Yes, CY8C4149AZAS568XQLA1 integrates a CAN FD controller with built-in physical layer drivers on dedicated CANFD_TX and CANFD_RX pins. It supports bit rates up to 5 Mbps, recessive-dominant transition timing compliant with ISO 11898-1:2015, and automatic bus-off recovery without software intervention.
Can all GPIO pins be used for CAPSENSE™ sensing simultaneously?
No - while any GPIO pin can be configured for CAPSENSE™, the Multi-Sense Converter (MSC) block supports up to 32 simultaneous sensing channels. Channel allocation is managed by the PDL library and constrained by routing resources; concurrent use of all 84 pins for CAPSENSE™ is not supported due to analog bus bandwidth limits.
Is ModusToolbox™ required for development with this device?
ModusToolbox™ is the recommended and fully supported IDE for CY8C4149AZAS568XQLA1, providing pre-validated Peripheral Driver Libraries (PDL), CAPSENSE™ Tuner, and CAN FD configuration tools. However, Arm®-compliant toolchains (e.g., Keil MDK, IAR Embedded Workbench) can be used with provided linker scripts and startup files - though SmartSense auto-tuning requires ModusToolbox™ integration.
