Product details
Overview
CY8C4149AZES555XQLA1 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 body control modules, smart sensors, and automotive HMI interfaces.
For engineers reviewing the CY8C4149AZES555XQLA1 datasheet, CY8C4149AZES555XQLA1 pinout, CY8C4149AZES555XQLA1 application, or CY8C4149AZES555XQLA1 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 flexibility (up to 84 pins, all CAPSENSE™-capable).
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, and dual opamps with Deep Sleep support. Its analog subsystem includes a 12-bit SAR ADC with temperature sensor, two low-power comparators, and CTBm blocks enabling programmable gain/feedback configurations.
Digital reconfigurability is implemented via Smart I/O logic blocks and programmable routing matrix, allowing Boolean operations on port signals without CPU intervention. The CAN FD block supports ISO 11898-1:2015 with bit rates up to 5 Mbps and flexible message filtering, while the MSC block delivers hardware-accelerated capacitive sensing with water-tolerant scanning and automatic calibration.

FAQ
What is the maximum operating temperature range for CY8C4149AZES555XQLA1?
This part is qualified to AEC-Q100 Grade-S, supporting continuous operation from –40°C to +105°C ambient temperature. It includes on-die thermal monitoring via the integrated SAR ADC temperature sensor, which is factory-calibrated and usable for system-level thermal management without external components.
Does CY8C4149AZES555XQLA1 support CAN FD with ISO 11898-1:2015 compliance?
Yes, the integrated CAN FD block fully complies with ISO 11898-1:2015, supporting data rates up to 5 Mbps, flexible data length (up to 64 bytes), and error confinement mechanisms. It includes dedicated message RAM, hardware filtering, and bit-rate switching capability required for automotive Ethernet coexistence.
Can all 84 GPIO pins be used simultaneously for CAPSENSE™ sensing?
No - while any GPIO pin can be configured for CAPSENSE™, the MSC block supports up to 32 physical sensing electrodes per scan cycle due to hardware resource limits in the multi-sense converter. Simultaneous use of all 84 pins requires time-multiplexed scanning across multiple groups.
Is ModusToolbox™ required to develop firmware for this device?
ModusToolbox™ is the recommended and fully supported IDE, providing Peripheral Driver Libraries (PDL), CAPSENSE™ Tuner, and CAN FD configuration tools. However, the device is Arm®-compliant and can also be programmed using GCC-based toolchains and OpenOCD with appropriate startup files and linker scripts provided in Infineon's GitHub repositories.
