Product details
Overview
CY8C4149AZS-S575 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™ touch interfaces, motor control via eight 16-bit TCPWM blocks with kill-signal triggering, and operates from 1.71 V to 5.5 V in Deep Sleep mode at 2.5 µA.
For engineers reviewing the CY8C4149AZS-S575 datasheet, CY8C4149AZS-S575 pinout, CY8C4149AZS-S575 application, or CY8C4149AZS-S575 equivalent, this device is selected for automotive body electronics requiring functional safety-aware analog-digital integration, robust capacitive sensing under moisture, and CAN FD communication in space-constrained ECUs.
Technical Context
The CY8C4149AZS-S575 implements a tightly coupled system-on-chip architecture where the Cortex-M0+ core interfaces via single-layer AHB-Lite to programmable analog (CTBm opamps, SAR ADC, LP comparators), digital (Smart I/O, TCPWM, SCBs), and domain-specific accelerators (MSC, Crypto, CAN FD). Its clock system integrates ECO+PLL (48 MHz), WCO, IMO (±2%), and ILO for mixed-mode timing control.
Analog signal chain flexibility is enabled by reconfigurable CTBm opamps supporting external high-drive or internal high-bandwidth modes with ADC input buffering, while the MSC block delivers hardware-accelerated capacitive sensing with SmartSense auto-tuning and water tolerance - both validated for automotive interior HMI applications per AEC-Q100 Grade-S requirements.

FAQ
What is the maximum operating frequency of the Arm® Cortex®-M0+ core in CY8C4149AZS-S575?
The Arm® Cortex®-M0+ core operates at a maximum frequency of 48 MHz, achieved via the internal PLL locked to an external crystal oscillator (ECO) ranging from 4 to 33 MHz. This frequency is fully supported across the full Grade-S temperature range (–40°C to +105°C) and all supply voltages (1.71 V to 5.5 V), with timing closure verified per AEC-Q100 requirements.
Does CY8C4149AZS-S575 support hardware-based cryptographic operations?
Yes, it includes a dedicated cryptography accelerator supporting AES-128/256 encryption/decryption, SHA-1/224/256 hashing, true random number generation (TRNG), CRC-32 computation, and PRNG functions. These are accessible via memory-mapped registers and integrated into the ModusToolbox™ PDL, enabling secure boot and firmware authentication without CPU overhead.
Can all GPIO pins be used for CAPSENSE™ functionality?
Yes, all 84 GPIO pins are configurable for CAPSENSE™ sensing via the Multi-Sense Converter (MSC) block. Each pin supports self- or mutual-capacitance measurement, and SmartSense auto-tuning dynamically adjusts scan parameters - including resolution, IDAC current, and averaging - to maintain SNR >5:1 under varying environmental conditions including moisture and ESD events.
What package type and lead finish does CY8C4149AZS-S575 use?
CY8C4149AZS-S575 uses a 64-pin TQFP package (10 mm × 10 mm, 0.5 mm pitch) with wettable flank geometry and lead-free (Pb-free) matte tin finish. This configuration supports automated optical inspection (AOI) and meets J-STD-020D moisture sensitivity level 3 (MSL3), enabling standard automotive reflow profiles without popcorn risk.
