Overview

CY8C4148AZAS575XQLA1 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, featuring 48 MHz operation, 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 CY8C4148AZAS575XQLA1 datasheet, CY8C4148AZAS575XQLA1 pinout, CY8C4148AZAS575XQLA1 application, or CY8C4148AZAS575XQLA1 equivalent, this device supports reconfigurable analog/digital blocks, Deep Sleep mode with 2.5 µA system current, hardware crypto acceleration (AES/SHA/TRNG), and five SCBs for I²C/SPI/UART/LIN - critical for automotive body control, infotainment HMI, and motor drive supervision.

Technical Context

The device implements a single-layer AHB-Lite interconnect between Cortex-M0+ CPU, memory subsystem (384 KB flash + 32 KB SRAM), and programmable peripherals including two CTBm opamps with Deep Sleep support, 12-bit 1-Msps SAR ADC with temperature sensor, and eight TCPWM blocks supporting quadrature decoding and comparator-triggered kill signals.

Its clock system integrates ECO (4–33 MHz) with PLL for 48 MHz core timing, WCO (32 kHz), IMO (±2%), and ILO (40 kHz); the CAN FD block operates independently at up to 5 Mbps with dedicated message RAM and filtering, while MSC enables robust CAPSENSE™ with SmartSense auto-tuning and water tolerance.

FAQ

What is the maximum operating frequency of the Arm® Cortex®-M0+ core in CY8C4148AZAS575XQLA1?

The core operates at a maximum frequency of 48 MHz, achieved via internal PLL locked to an external crystal oscillator (ECO) ranging from 4 to 33 MHz. This frequency is guaranteed across the full Grade-S temperature range (–40°C to +105°C) and supply voltage range (1.71 V to 5.5 V), with cycle-accurate timing supported by the Read Accelerator for flash access.

Does CY8C4148AZAS575XQLA1 support CAN FD with ISO 11898-1 physical layer compliance?

Yes, the integrated CAN FD controller supports bit rates up to 5 Mbps and complies with ISO 11898-1 for physical layer signaling. It includes configurable slew rate control, internal termination, loopback test mode, and dedicated message RAM with hardware filtering - all verified per AEC-Q100 stress testing for automotive deployment.

How many GPIO pins support CAPSENSE™ functionality, and what is the minimum detectable capacitance change?

All 84 programmable GPIO pins can be configured for CAPSENSE™ sensing. The Multi-Sense Converter (MSC) achieves a signal-to-noise ratio exceeding 5:1, enabling reliable detection of sub-1 fF capacitance changes - validated under condensation, salt fog, and glove-touch conditions per IEC 61000-4-6 immunity testing.

Is hardware cryptographic acceleration available, and which algorithms are implemented in silicon?

Yes, the on-die Crypto block implements AES-128/256 (ECB/CBC/CTR modes), SHA-1/256, CRC-32, TRNG, and PRNG - all accessible via DMA-linked peripheral interfaces. These accelerators operate independently of the CPU, achieving zero-wait-state throughput and supporting secure boot, firmware signing, and encrypted CAN FD payload protection.
