Product details
Overview
CY8C4147AZAS548XQLA1 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 multi-sense capacitive sensing (MSC) with >5:1 SNR for touch interfaces in harsh environments.
For engineers reviewing the CY8C4147AZAS548XQLA1 datasheet, CY8C4147AZAS548XQLA1 pinout, CY8C4147AZAS548XQLA1 application, or CY8C4147AZAS548XQLA1 equivalent, this device supports reconfigurable analog/digital blocks, Deep Sleep mode at 2.5 µA, hardware crypto acceleration (AES/SHA/TRNG), and five SCBs for flexible I²C/SPI/UART/LIN operation - critical for automotive body control, sensor fusion, and infotainment HMI design.
Technical Context
The CY8C4147AZAS548XQLA1 implements a tightly coupled system-on-chip architecture with single-layer AHB-Lite interconnect, enabling concurrent access to flash (with Read Accelerator), SRAM, and peripherals including dual opamps, 12-bit SAR ADC (1 Msps), and eight TCPWM blocks supporting quadrature decoding and comparator-triggered kill signals for motor safety logic.
Its clock system integrates ECO (4–33 MHz) + PLL for 48-MHz core timing, WCO (32 kHz), IMO (±2%), and ILO (40 kHz), while the CAN FD block operates independently with dedicated message RAM and bit-rate switching up to 5 Mbps - meeting ISO 11898-1:2015 requirements for automotive networked subsystems.

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 @ 112 MHz, 1 MB flash, no integrated capacitive sensing block | Higher performance for motor control algorithms but requires external touch controller | Select when floating-point math or CAN FD routing flexibility outweighs integrated MSC cost savings |
| Renesas RL78/F14 | 16-bit RL78 core @ 32 MHz, 512 KB flash, AEC-Q100 Grade-2 (–40°C to +105°C), no CAN FD | Lower gate count for simple body electronics; lacks hardware crypto and MSC | Select for cost-sensitive, non-safety-critical modules where CAN FD and secure boot are not required |

FAQ
What is the maximum operating temperature range for CY8C4147AZAS548XQLA1?
CY8C4147AZAS548XQLA1 is qualified to AEC-Q100 Grade-S, supporting continuous operation from –40°C to +105°C ambient temperature. This rating is verified per stress-test conditions defined in the qualification report, and applies to all functional blocks including flash, SRAM, CAN FD, and MSC under full voltage and clock specifications.
Does CY8C4147AZAS548XQLA1 support hardware-based secure boot?
Yes - it includes a dedicated cryptography accelerator with AES-128/256, SHA-256, TRNG, and CRC engines, enabling authenticated secure boot via immutable ROM bootloader. The TRNG provides entropy for key generation, and flash protection registers prevent unauthorized read-out of boot images.
Can the MSC block be used for proximity sensing in wet environments?
Yes - the Multi-Sense Converter (MSC) achieves >5:1 signal-to-noise ratio and includes hardware-based water rejection algorithms. Combined with SmartSense auto-tuning, it maintains stable electrode capacitance measurement even during condensation or light water film exposure on overlay surfaces.
How many CAN FD channels does CY8C4147AZAS548XQLA1 support?
CY8C4147AZAS548XQLA1 integrates one CAN FD controller with dedicated message RAM, supporting bit rates up to 5 Mbps in data phase and full ISO 11898-1:2015 compliance. It does not support multiple independent CAN FD buses - only a single physical CAN_FD_TX/RX pair is implemented.
