Infineon Technologies CY8C4148LDAS583XQLA1

Overview

CY8C4148LDAS583XQLA1 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, 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 CY8C4148LDAS583XQLA1 datasheet, CY8C4148LDAS583XQLA1 pinout, CY8C4148LDAS583XQLA1 application, or CY8C4148LDAS583XQLA1 equivalent, key selection considerations include its CAN FD interface, Deep Sleep current of 2.5 µA with operational analog, 12-bit 1-Msps SAR ADC with temperature sensor, and 84 GPIOs supporting configurable 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 dedicated CAN FD controller - enabling concurrent I2C/SPI/UART/LIN and high-speed CAN FD communication without CPU overhead. Its programmable analog subsystem includes two opamps with Deep Sleep operation, dual low-power comparators, and a SAR ADC with hardware-averaging sequencer.

Timing is managed by multiple independent clock sources: 4–33 MHz ECO with PLL for 48 MHz system clock, 32-kHz WCO, ±2% IMO, and 40-kHz ILO - all supporting dynamic clock switching across power modes. The MSC block delivers >5:1 SNR and water-tolerant capacitive sensing via hardware-accelerated SmartSense tuning.

FAQ

What is the maximum operating frequency of the Arm® Cortex®-M0+ core in CY8C4148LDAS583XQLA1?

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 full Grade-S temperature range (–40°C to +105°C) and all supply voltages from 1.71 V to 5.5 V.

Does CY8C4148LDAS583XQLA1 support CAN FD in both data and arbitration phases?

CY8C4148LDAS583XQLA1 supports CAN FD with bit rates up to 5 Mbps in the data phase while maintaining Classical CAN arbitration at up to 1 Mbps. The CAN FD block implements ISO 11898-1:2015 compliant framing, CRC calculation, and automatic protocol handling - no software intervention is required for frame assembly or error detection.

How many CAPSENSE™ sensors can be implemented simultaneously on this device?

The device supports up to 84 self-capacitive or mutual-capacitive sensors using its Multi-Sense Converter (MSC) block, with hardware-accelerated SmartSense auto-tuning. All GPIO pins are CAPSENSE™-capable, and simultaneous scanning of ≥32 sensors is achievable within 10 ms at typical SNR conditions, depending on electrode layout and noise environment.

Is the 12-bit SAR ADC capable of performing conversions during Deep Sleep mode?

Yes, the 12-bit SAR ADC can operate in Deep Sleep mode with autonomous channel sequencing and hardware averaging enabled. It supports wake-up on conversion completion or threshold crossing using the integrated comparators, allowing low-power periodic sensor sampling without CPU intervention - critical for battery-backed automotive modules.
