Product details
Overview
CY8C4149AZES575XQLA1 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 for robust capacitive touch in harsh environments. It targets body control modules and infotainment interfaces requiring reconfigurable analog/digital peripherals and deep-sleep operation at 2.5 µA.
For engineers reviewing the CY8C4149AZES575XQLA1 datasheet, CY8C4149AZES575XQLA1 pinout, CY8C4149AZES575XQLA1 application, or CY8C4149AZES575XQLA1 equivalent, key selection criteria include CAN FD timing compliance, Deep Sleep current under active analog sensing, TCPWM kill-signal triggering for motor safety, and MSC hardware auto-tuning (SmartSense) for wet-finger tolerance in automotive HMI.
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, SCBs, Smart I/O), and system resources (IMO/ILO/WCO/ECO clocks, Crypto accelerators). All analog blocks-including opamps and comparators-remain functional in Deep Sleep mode with 2.5 µA system current.
Its five Serial Communication Blocks (SCBs) support runtime-reconfigurable I²C/SPI/UART/LIN Slave modes, while the dedicated CAN FD block operates independently at up to 5 Mbps with protocol-level error handling and bit-rate switching-enabling integration into modern automotive domain controllers without external transceivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0+, 48 MHz max - enables deterministic real-time control with Thumb-2 instruction set and NVIC interrupt management. |
| Flash / SRAM | 384 KB flash with Read Accelerator; 32 KB SRAM - supports complex automotive firmware with fast code execution and data buffering for sensor fusion. |
| CAN FD Speed | Up to 5 Mbps data phase - meets high-bandwidth requirements for ADAS sensor aggregation and ECU diagnostics. |
| SAR ADC | 12-bit, 1 Msps, differential/single-ended, integrated temperature sensor - provides accurate battery monitoring and thermal management without external components. |
| Deep Sleep Current | 2.5 µA with operational analog - sustains capacitive wake-up detection and low-power timer functions during vehicle sleep mode. |
| CAPSENSE™ SNR | >5:1 signal-to-noise ratio with SmartSense auto-tuning - ensures reliable touch response under condensation, glove use, and EMI-rich cabin environments. |
| GPIO Count | Up to 84 pins, all configurable as CAPSENSE™, analog, or digital - simplifies PCB layout by eliminating dedicated sense lines and enabling flexible HMI routing. |
Pinout & Package
This device is packaged in a 100-pin TQFP (Thin Quad Flat Package) with 0.5 mm pitch, lead-free and RoHS-compliant, designed for automotive-grade thermal and mechanical reliability under vibration and thermal cycling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDIO0–VDDIO7 | I/O power supply domains | Independent 1.71–5.5 V supplies per port group enable mixed-voltage interfacing (e.g., 3.3 V MCU logic with 5 V sensors). |
| P0[0]–P7[7] | Programmable GPIOs | All pins support CAPSENSE™, analog input, digital logic, and LCD segment drive - no fixed-function pin constraints. |
| CANFD_TX / CANFD_RX | Dedicated CAN FD physical layer interface | Direct connection to external CAN FD transceiver; supports ISO 11898-1:2015 compliant signaling without software bit-banging. |
| XTAL_IN / XTAL_OUT | External crystal oscillator inputs | Supports 4–33 MHz ECO for precise clock generation; PLL locks to generate stable 48 MHz system clock. |
| SWDCLK / SWDIO | ARM Serial Wire Debug interface | Enables non-intrusive debug, flash programming, and real-time trace via standard Cortex-M debug infrastructure. |
Key Features
| Feature | Design Value |
|---|---|
| Hardware SmartSense tuning | Automatically adjusts CAPSENSE™ baseline, IDAC, and scanning parameters in real time to maintain SNR >5:1 under moisture, temperature drift, or EMI. |
| TCPWM kill-input triggering | Hardware-level immediate PWM shutdown on comparator output assertion - eliminates software latency in motor overcurrent/fault protection. |
| Reconfigurable SCBs | Five independent serial blocks each dynamically assignable as I²C master/slave, SPI master/slave, UART, or LIN Slave - reduces peripheral count and BOM cost. |
| Crypto acceleration | Dedicated AES-128/256, SHA-256, TRNG, and CRC engines offload security-critical tasks from CPU, preserving deterministic timing for safety-critical routines. |
| Multi-domain I/O power | Eight independent VDDIO rails allow simultaneous interfacing with 1.8 V, 3.3 V, and 5 V peripherals without level shifters or voltage translators. |
Applications

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 core, 112 MHz; includes Ethernet MAC but lacks integrated CAPSENSE™ and SmartSense. | Better suited for gateway/communication-heavy roles; requires external touch controller for HMI. | Select when floating-point math or Ethernet connectivity outweighs capacitive sensing integration. |
| Renesas RL78/F14 | 16-bit RL78 core, 32 MHz; AEC-Q100 qualified but no CAN FD or hardware crypto acceleration. | Targeted at cost-sensitive body electronics with basic CAN 2.0B only. | Select for legacy CAN-only systems where flash size <256 KB and no FD bandwidth is required. |
Compared with S32K144HAT0MLHT and RL78/F14, CY8C4149AZES575XQLA1 uniquely combines CAN FD, CAPSENSE™ SmartSense, and Deep Sleep analog operation in a single die-making it optimal for next-gen automotive HMI nodes where integration, power efficiency, and wet-finger tolerance are design-critical.

FAQ
Does CY8C4149AZES575XQLA1 require an external CAN transceiver?
Yes, CY8C4149AZES575XQLA1 contains a CAN FD controller only-not a physical layer transceiver. It must be paired with a compliant external CAN FD transceiver (e.g., Infineon TLE9251VS) for bus communication. The device provides dedicated CANFD_TX and CANFD_RX pins with configurable slew rate and drive strength to match transceiver input requirements.
What is the maximum operating temperature grade for this part?
CY8C4149AZES575XQLA1 is qualified to AEC-Q100 Grade-S, supporting continuous operation from –40°C to +105°C ambient temperature. This rating covers under-hood and cabin-mounted applications including HVAC controls and center-stack touch interfaces, validated per stress-test conditions defined in AEC-Q100 Rev-G.
Can the SAR ADC perform simultaneous sampling across multiple channels?
No, the 12-bit SAR ADC has a single conversion engine and supports sequential channel scanning via hardware channel sequencer with signal averaging-but not true simultaneous sampling. For multi-channel synchronized acquisition, external analog multiplexing or parallel ADCs are required. The sequencer supports up to 16-channel automatic scan with programmable sample-and-hold timing.
Is ModusToolbox™ support included with this device?
Yes, CY8C4149AZES575XQLA1 is fully supported in Infineon's ModusToolbox™ 3.x IDE, including Peripheral Driver Library (PDL) APIs for TCPWM, SCB, CAN FD, CAPSENSE™, and Crypto blocks. Pre-built code examples, configurators for clock tree and pinmux, and debug probe compatibility (KitProg3, J-Link) are provided at no license cost.
