Product details
Overview
CY8C4149AZAS585XQLA1 from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-grade 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 supports CAPSENSE™, LCD segment drive, five reconfigurable SCBs (I²C/SPI/UART/LIN), and hardware crypto accelerators (AES, SHA, TRNG).
For engineers reviewing the CY8C4149AZAS585XQLA1 datasheet, CY8C4149AZAS585XQLA1 pinout, CY8C4149AZAS585XQLA1 application, or CY8C4149AZAS585XQLA1 equivalent, key selection criteria include CAN FD timing compliance, Deep Sleep current (2.5 µA), MSC water-tolerance capability, programmable analog routing, and ModusToolbox™ API support for rapid CAPSENSE™ and TCPWM configuration.
Technical Context
The device implements a single-layer AHB-Lite interconnect linking the Cortex-M0+ core, DMA engine, and peripherals including eight 16-bit TCPWM blocks with quadrature decode and comparator-triggered kill signals-critical for motor control safety. Its analog subsystem integrates two CTBm opamps (operable in Deep Sleep), a 12-bit 1-Msps SAR ADC with temperature sensor, and dual low-power comparators.
Digital flexibility is enabled by Smart I/O logic, five SCBs supporting runtime reconfiguration across I²C/SPI/UART/LIN protocols, and a dedicated CAN FD controller compliant with ISO 11898-1:2015. Clocking includes ECO (4–33 MHz) + PLL, WCO (32 kHz), IMO (±2%), and ILO (40 kHz), enabling precise timing across sleep/wake transitions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP S32K144W | ARM Cortex-M4F core, 112 MHz; includes Ethernet MAC but lacks integrated CAPSENSE™ and MSC block. | Better suited for gateway ECUs requiring CAN FD + Ethernet bridging; less optimal for cost-sensitive HMI with capacitive touch. | Select when Ethernet connectivity or floating-point math performance is required over integrated analog sensing. |
| Renesas RL78/F14 | 16-bit RL78 core, 32 MHz; AEC-Q100 Grade 2 (–40°C to +105°C); no CAN FD, no hardware crypto, no MSC. | Targeted at basic body electronics where CAN FD bandwidth and security are not mandated. | Choose only for legacy 16-bit migration paths with minimal feature uplift and no future CAN FD roadmap. |
Compared with S32K144W and RL78/F14, CY8C4149AZAS585XQLA1 uniquely combines CAN FD, hardware crypto, and best-in-class CAPSENSE™ in a single AEC-Q100 Grade-S package-making it optimal for next-gen automotive HMI and distributed control nodes where analog integration and security coexist.

FAQ
What is the maximum operating frequency of the Arm® Cortex®-M0+ core in CY8C4149AZAS585XQLA1?
The Arm® Cortex®-M0+ core operates at up to 48 MHz, achieved via internal PLL locked to an external crystal oscillator (ECO) or the ±2% internal main oscillator (IMO). This frequency is fully supported across all AEC-Q100 temperature grades and power modes, including Active and Sleep, and is validated for sustained operation under automotive thermal stress conditions.
Does CY8C4149AZAS585XQLA1 support CAN FD with ISO 11898-1:2015 compliance?
Yes, the integrated CAN FD block supports bit rates up to 5 Mbps and complies with ISO 11898-1:2015 for physical layer timing, arbitration, and error handling. It includes programmable bit timing registers, automatic retransmission, and loopback self-test mode-enabling full protocol stack implementation without external transceivers beyond standard CAN PHY.
How many GPIO pins can be used simultaneously for CAPSENSE™ sensing?
All 84 GPIO pins are individually configurable for CAPSENSE™, with hardware support for mutual-capacitance (Cx) and self-capacitance (Cx) scanning. The MSC block enables concurrent scanning of up to 64 electrodes using SmartSense auto-tuning, and the analog routing matrix allows direct connection of any GPIO to the MSC without external components.
Is ModusToolbox™ software required to configure the programmable analog blocks?
No-ModusToolbox™ is recommended but not required. The PDL (Peripheral Driver Library) provides C APIs for runtime configuration of CTBm opamps, SAR ADC, and comparators. However, ModusToolbox™'s Configurator GUI significantly accelerates analog signal chain setup (e.g., PGA gain, filter cutoff, ADC sequencing) and generates verified initialization code compatible with GCC and Arm Compiler toolchains.
