Product details
Overview
CY8C4149LDSS553XQLA1 from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-qualified 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 targets body control modules, smart sensors, and automotive HMI systems requiring robust capacitive touch under wet conditions.
For engineers reviewing the CY8C4149LDSS553XQLA1 datasheet, CY8C4149LDSS553XQLA1 pinout, CY8C4149LDSS553XQLA1 application, or CY8C4149LDSS553XQLA1 equivalent, key selection considerations include CAN FD timing compliance, Deep Sleep analog retention (2.5 µA system current), MSC water-tolerant sensing, and reconfigurable SCB peripherals supporting I²C/SPI/UART/LIN in runtime.
Technical Context
The device integrates a single-layer AHB-Lite interconnect linking the Cortex-M0+ core to programmable analog (CTBm opamps, SAR ADC, LP comparators), digital (TCPWM, Smart I/O), and connectivity blocks (5 SCBs, CAN FD, I2S TX Master). All analog blocks-including opamps and comparators-retain operation in Deep Sleep mode with 2.5 µA total system current.
Its clock system combines a 4–33 MHz ECO with PLL (generating 48 MHz), 32-kHz WCO, ±2% IMO, and 40-kHz ILO-enabling precise timing for motor control (quadrature decode, kill-signal triggering) and low-power wake-up events. The MSC block delivers hardware-accelerated capacitive sensing with SmartSense auto-tuning.

FAQ
What is the maximum operating temperature range for CY8C4149LDSS553XQLA1?
CY8C4149LDSS553XQLA1 is qualified to AEC-Q100 Grade-S, supporting continuous operation from –40°C to +105°C. This rating is validated across all silicon, package, and electrical parameters per the official Infineon datasheet Rev. *G. No derating is required within this range for automotive under-hood or cabin applications.
Does CY8C4149LDSS553XQLA1 support hardware-based CAN FD bit-rate switching?
Yes. The integrated CAN FD controller supports automatic bit-rate switching between nominal (up to 1 Mbps) and data-phase (up to 5 Mbps) segments per ISO 11898-1:2015. Configuration is handled via register-level control in the CANFDx_CTL register set, with dedicated FIFOs and error counters for both phases.
Can all 84 GPIOs be used simultaneously for CAPSENSE™ sensing?
No. While all GPIOs are CAPSENSE™-capable, the MSC block supports up to 64 simultaneous sensing electrodes due to hardware resource limits in the analog front-end and scan sequencer. Using more than 64 electrodes requires time-multiplexed scanning, which reduces effective update rate and increases noise susceptibility.
Is ModusToolbox™ required to configure the programmable analog blocks?
No. ModusToolbox™ provides GUI-based configuration and code generation for CTBm opamps, SAR ADC, and MSC, but all analog blocks can be configured directly via register writes using the PDL API or bare-metal C. Full register maps and initialization sequences are documented in the PSoC™ 4100S Max Technical Reference Manual.
