Product details
Overview
CY8C4149AZES578XQLA1 from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-qualified PSoC™ 4100S Max microcontroller based on Arm® Cortex®-M0+ CPU running at 48 MHz, featuring 384 KB flash, 32 KB SRAM, CAN FD up to 5 Mbps, 12-bit 1-Msps SAR ADC, and integrated CAPSENSE™ with SmartSense auto-tuning. It targets body control modules and in-cabin human-machine interface systems requiring robust capacitive touch and real-time motor control.
For engineers reviewing the CY8C4149AZES578XQLA1 datasheet, CY8C4149AZES578XQLA1 pinout, CY8C4149AZES578XQLA1 application, or CY8C4149AZES578XQLA1 equivalent, key selection considerations include CAN FD timing compliance, Deep Sleep current (2.5 µA), GPIO reconfigurability for analog/digital/CAPSENSE™, and hardware cryptographic acceleration (AES/SHA/TRNG).
Technical Context
The device implements a dual-domain clock architecture with independent IMO (±2%), ILO (40 kHz), WCO (32.768 kHz), and ECO (4–33 MHz) sources, plus PLL for precise 48-MHz system clock generation. Its programmable analog subsystem includes two opamps supporting high-drive external mode and ADC input buffering, both operational in Deep Sleep.
Digital flexibility is enabled by five reconfigurable Serial Communication Blocks (SCBs) supporting I²C/SPI/UART/LIN Slave simultaneously, eight TCPWM blocks with quadrature decode and comparator-triggered kill signals, and a dedicated CAN FD controller compliant with ISO 11898-1:2015 supporting data rates up to 5 Mbps.
Key Specifications

FAQ
What is the maximum operating temperature range for CY8C4149AZES578XQLA1?
This part is qualified to AEC-Q100 Grade-S, with guaranteed operation from –40°C to +105°C ambient temperature. The specification includes full functionality of all peripherals-including CAN FD, SAR ADC, and CAPSENSE™-within this range, validated under automotive thermal cycling profiles.
Does CY8C4149AZES578XQLA1 support hardware-based CAN FD bit-rate switching?
Yes, it implements full ISO 11898-1:2015 CAN FD compliance including automatic bit-rate switching between nominal (≤1 Mbps) and data (up to 5 Mbps) phases. The CAN FD block handles arbitration and data phase transitions autonomously without CPU intervention.
Can all 84 GPIOs be used simultaneously for CAPSENSE™ electrode scanning?
No-while all GPIOs are CAPSENSE™-capable, the Multi-Sense Converter (MSC) block supports up to 64 electrodes per scan group. Simultaneous use of all 84 pins requires time-multiplexed scanning across multiple groups, managed by the MSC hardware sequencer.
Is ModusToolbox™ required to configure the programmable analog blocks?
No-ModusToolbox™ provides GUI-based configuration and auto-generated PDL code, but the CTBm opamps, SAR ADC, and comparators can also be configured directly via register writes using the documented memory-mapped addresses and bit definitions in the TRM.
