Product details
Overview
CY8C4149AZAS548XQLA1 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, featuring 48 MHz operation, 384 KB flash, 32 KB SRAM, CAN FD up to 5 Mbps, and integrated CAPSENSE™ with SmartSense auto-tuning. It targets body control modules, smart sensors, and automotive HMI systems requiring robust capacitive touch in harsh environments.
For engineers reviewing the CY8C4149AZAS548XQLA1 datasheet, CY8C4149AZAS548XQLA1 pinout, CY8C4149AZAS548XQLA1 application, or CY8C4149AZAS548XQLA1 equivalent, key selection criteria include CAN FD timing compliance, Deep Sleep current (2.5 µA), SAR ADC resolution (12-bit, 1 Msps), MSC SNR (>5:1), and GPIO reconfigurability across analog/digital/CAPSENSE™ functions.
Technical Context
The device integrates a single-layer AHB-Lite interconnect linking the Cortex-M0+ core, 5 reconfigurable Serial Communication Blocks (SCBs), and a dedicated CAN FD controller supporting ISO 11898-1:2015 with bit rates up to 5 Mbps and flexible data field lengths. Its clock system combines ECO (4–33 MHz), PLL (generating 48 MHz), WCO (32 kHz), and low-power ILO (40 kHz) for deterministic timing across sleep/wake transitions.
Analog subsystem includes two CTBm opamps operable in Deep Sleep mode, a 12-bit SAR ADC with differential input and hardware-averaging sequencer, two low-power comparators, and a multi-sense converter (MSC) block delivering >5:1 SNR and water-tolerant capacitive sensing-enabled by SmartSense automatic hardware tuning without host CPU intervention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0+, 48 MHz max - enables real-time deterministic control with Thumb-2 instruction set and NVIC interrupt handling. |
| Flash / SRAM | 384 KB flash with Read Accelerator; 32 KB SRAM - supports complex automotive firmware with fast code execution and buffer-intensive sensor processing. |
| CAN FD | Up to 5 Mbps data rate, ISO 11898-1:2015 compliant - meets high-bandwidth vehicle network requirements for ADAS sensor fusion and gateway routing. |

FAQ
What is the maximum operating temperature range for CY8C4149AZAS548XQLA1?
CY8C4149AZAS548XQLA1 is qualified to AEC-Q100 Grade-S, supporting continuous operation from –40°C to +105°C. This rating is validated per stress test conditions including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing-ensuring reliability in under-hood and cabin-mounted automotive applications.
Does CY8C4149AZAS548XQLA1 support CAN FD with ISO 11898-1:2015 compliance?
Yes, the integrated CAN FD controller fully complies with ISO 11898-1:2015, supporting data rates up to 5 Mbps, flexible data field lengths (up to 64 bytes), and error confinement mechanisms. It includes dedicated message RAM, transmit/receive FIFOs, and bit timing configuration registers accessible via PDL APIs in ModusToolbox™.
How does SmartSense auto-tuning improve CAPSENSE™ performance in wet conditions?
SmartSense dynamically adjusts sensor scan parameters-including modulation frequency, IDAC current, and sample count-based on real-time SNR feedback from the MSC block. This hardware-accelerated process maintains >5:1 signal-to-noise ratio even with water films up to 1 mm thick, eliminating false triggers and manual recalibration across temperature and humidity gradients.
Can CY8C4149AZAS548XQLA1 operate in Deep Sleep mode while maintaining analog functionality?
Yes, Deep Sleep mode retains full operation of the MSC block, two opamps, and two low-power comparators while drawing only 2.5 µA total system current. The Cortex-M0+ core and most digital peripherals are powered down, but analog subsystems remain active-enabling continuous capacitive wake detection or analog threshold monitoring without CPU intervention.
