Product details
Overview
CY8C4149AZSS548XQLA1 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 CAPSENSE™ multi-sense converter with >5:1 SNR. It supports capacitive touch, motor control, and body electronics in automotive ECUs.
For engineers reviewing the CY8C4149AZSS548XQLA1 datasheet, CY8C4149AZSS548XQLA1 pinout, CY8C4149AZSS548XQLA1 application, or CY8C4149AZSS548XQLA1 equivalent, key selection criteria include CAN FD timing compliance, Deep Sleep current (2.5 µA), SAR ADC resolution (12-bit, 1-Msps), MSC water tolerance, and GPIO reconfigurability across analog/digital/CAPSENSE™ functions.
Technical Context
The device integrates a single-layer AHB-Lite interconnect linking CPU, DMA, flash, SRAM, and peripherals including five reconfigurable Serial Communication Blocks (SCBs) supporting I²C/SPI/UART/LIN, eight 16-bit TCPWM blocks with quadrature decode and comparator-triggered kill signals, and a dedicated CAN FD controller compliant with ISO 11898-1:2015.
Analog subsystem includes two continuous-time opamps (CTBm) with Deep Sleep operation, a 12-bit SAR ADC with temperature sensor and channel sequencer, two low-power comparators, and a multi-sense converter (MSC) optimized for high-noise automotive environments with hardware SmartSense auto-tuning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0+, 48 MHz - enables real-time deterministic control for automotive body modules and sensor fusion. |
| Flash / SRAM | 384 KB flash with Read Accelerator / 32 KB SRAM - supports complex firmware with secure boot and OTA update partitions. |
| CAN FD Speed | Up to 5 Mbps data phase - meets high-bandwidth requirements for ADAS domain controllers and gateway ECU communication. |
| SAR ADC | 12-bit, 1-Msps, differential/single-ended, with signal averaging - delivers precise battery voltage, temperature, and sensor monitoring in noisy power domains. |
| Deep Sleep Current | 2.5 µA digital system current - enables always-on wake-on-touch or wake-on-CAN while meeting automotive low-power budget constraints. |
| CAPSENSE™ SNR | >5:1 signal-to-noise ratio - ensures reliable capacitive button/slider operation under condensation, glove use, and ESD stress per ISO 10605. |

Pinout & Package
Package: 100-pin TQFP (14 mm × 14 mm, 0.5 mm pitch), RoHS-compliant, wettable flank option for automated optical inspection (AOI).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P0[0]–P0[7] | Port 0 GPIO bank | Supports CAPSENSE™, analog input (ADC/SAR), opamp output, or SCB/I²C - configurable per-pin drive strength/slew rate. |
| P1[0]–P1[7] | Port 1 GPIO bank | Includes CAN FD TX/RX (P1[2]/P1[3]), TCPWM capture inputs, and LCD segment outputs - enables mixed-signal HMI integration. |

| VDDD / VDDA | Digital/analog core supplies | Separate 1.71–5.5 V domains with internal LDO regulation - isolates noise-sensitive analog blocks from digital switching transients. |
Key Features
| Feature | Design Value |
|---|---|
| Hardware SmartSense tuning | Automatic MSC calibration without host CPU intervention - reduces firmware development time for touch UIs and eliminates manual threshold tuning in production. |
| Programmable Smart I/O | Boolean logic on port inputs/outputs - implements debounce, edge detection, or pulse stretching in hardware, freeing CPU cycles for safety-critical tasks. |
| Crypto accelerators | AES-128/256, SHA-256, TRNG, CRC - enables secure bootloader authentication, encrypted CAN FD message signing, and anti-cloning protection per UNECE R155. |
| Deep Sleep analog retention | Opamps, comparators, and MSC remain active at 2.5 µA - supports wake-on-capacitive-event or wake-on-analog-threshold without full MCU wake-up latency. |
| Reconfigurable SCBs | Five independent blocks each supporting I²C/SPI/UART/LIN in runtime - simplifies BOM consolidation by eliminating discrete protocol translators in multi-sensor clusters. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP S32K144HAT0MLHT | ARM Cortex-M4F @ 112 MHz, 1 MB flash, no integrated CAPSENSE™, requires external touch controller | Better floating-point performance for motor FOC, but higher BOM cost and layout complexity for touch interfaces | Select when advanced motor control algorithms dominate over HMI integration needs |
| Renesas RL78/F14 | 16-bit RL78 core @ 32 MHz, 512 KB flash, CAN 2.0B only, no CAN FD or hardware crypto | Limited to legacy automotive networks; lacks hardware security for UNECE R155 compliance | Select only for cost-sensitive, non-connected body electronics with no future OTA or cybersecurity requirements |
Compared with S32K144HAT0MLHT and RL78/F14, CY8C4149AZSS548XQLA1 uniquely combines CAN FD, CAPSENSE™, and hardware crypto in a single AEC-Q100 Grade-S package-enabling consolidated HMI + connectivity + security functionality without external components.

FAQ
What is the maximum operating temperature range for CY8C4149AZSS548XQLA1?
This part is qualified to AEC-Q100 Grade-S, with guaranteed operation from –40°C to +105°C ambient temperature. The specification is validated across all silicon revisions and includes thermal derating for sustained operation at maximum junction temperature (125°C) under defined power dissipation conditions per datasheet Section 6.1.
Does CY8C4149AZSS548XQLA1 support CAN FD ISO 11898-1:2015 physical layer compliance?
Yes - the integrated CAN FD block supports bit rates up to 5 Mbps in the data phase and complies with ISO 11898-1:2015 electrical specifications when paired with a certified CAN FD transceiver (e.g., Infineon TLE9251VS). Loopback and bus-off recovery are handled in hardware with minimal CPU overhead.
Can the SAR ADC perform simultaneous sampling across multiple channels?
No - the 12-bit SAR ADC uses a single conversion engine with a channel sequencer that supports automatic scanning and signal averaging, but does not provide true simultaneous sampling. For synchronized multi-channel acquisition, external analog multiplexing or parallel ADCs are required.
Is ModusToolbox™ software required to configure the programmable analog blocks?
ModusToolbox™ is the recommended and fully supported IDE, providing graphical configuration of CTBm opamps, SAR ADC, and MSC through the PSoC™ Creator-compatible Peripheral Driver Library (PDL). While register-level access is possible, hardware initialization, calibration, and SmartSense tuning require ModusToolbox™-generated startup code.
