Infineon Technologies CY8C4147AZAS585XQLA1

Overview

CY8C4147AZAS585XQLA1 from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-grade 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 requiring robust capacitive sensing and real-time motor control.

For engineers reviewing the CY8C4147AZAS585XQLA1 datasheet, CY8C4147AZAS585XQLA1 pinout, CY8C4147AZAS585XQLA1 application, or CY8C4147AZAS585XQLA1 equivalent, this page delivers verified technical context, package mapping, functional alternatives, and supply-ready availability for automotive embedded design validation and production BOM planning.

Technical Context

The device integrates a single-layer AHB-Lite interconnect linking the Cortex-M0+ core, 5 reconfigurable Serial Communication Blocks (SCBs), and 8 TCPWM blocks supporting center-aligned PWM and quadrature decoding. Its analog subsystem includes two opamps with Deep Sleep operation, dual low-power comparators, and a temperature-sensor-integrated SAR ADC.

The CAN FD block operates independently at up to 5 Mbps with dedicated message RAM and hardware filtering, while the MSC block delivers >5:1 SNR for wet-finger tolerant capacitive touch in automotive interiors. Clocking combines ECO+PLL (48 MHz), WCO (32 kHz), and ILO (40 kHz) for precise timing across sleep/wake transitions.

FAQ

What is the maximum operating frequency of the Arm® Cortex®-M0+ core in CY8C4147AZAS585XQLA1?

The Arm® Cortex®-M0+ core operates at a maximum frequency of 48 MHz, achieved using the internal main oscillator (IMO) with PLL multiplication or an external crystal oscillator (ECO) with PLL. This frequency is fully supported across the entire Grade-S temperature range (–40°C to +105°C) and is validated per AEC-Q100 stress testing protocols.

Does CY8C4147AZAS585XQLA1 support CAN FD with hardware message RAM and filtering?

Yes, it includes a dedicated CAN FD block with 128-byte message RAM, hardware acceptance filtering, and bit-rate switching support up to 5 Mbps. The block operates independently of the CPU and supports interrupt-driven or DMA-based message handling, enabling deterministic latency for time-critical automotive messaging.

How many GPIO pins support CAPSENSE™ functionality, and what is the minimum recommended trace length?

All 84 GPIO pins support CAPSENSE™ sensing. For optimal SNR, Infineon recommends trace lengths ≤ 25 mm with 5-mil width and ground guard traces on adjacent layers. Longer traces require layout-specific tuning via SmartSense, and wettable flank TQFP packaging ensures AOI-compatible solder joint inspection.

Is the 12-bit SAR ADC capable of simultaneous sampling across multiple channels?

No, the SAR ADC uses a single conversion engine with a channel sequencer and supports sequential sampling at up to 1 Msps. Signal averaging across up to 64 samples per channel is supported in hardware, but true simultaneous sampling requires external analog multiplexing or a separate ADC.
