Infineon Technologies CY8C4148AZAS585XQLA1

Overview

CY8C4148AZAS585XQLA1 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 and in-vehicle human-machine interface systems requiring robust capacitive touch under wet conditions.

For engineers reviewing the CY8C4148AZAS585XQLA1 datasheet, CY8C4148AZAS585XQLA1 pinout, CY8C4148AZAS585XQLA1 application, or CY8C4148AZAS585XQLA1 equivalent, key selection criteria include CAN FD timing compliance, Deep Sleep current ≤2.5 µA with active analog, 12-bit SAR ADC with temperature sensor, programmable opamp modes, and GPIO reconfigurability across analog/digital/CAPSENSE™ functions.

Technical Context

The device implements a single-layer AHB-Lite interconnect between Cortex-M0+ core, memory subsystem (384 KB flash + 32 KB SRAM), and peripherals including five reconfigurable Serial Communication Blocks (SCBs), eight TCPWM units, and dual CTBm opamps supporting high-drive external and high-bandwidth internal modes. All analog blocks remain functional in Deep Sleep mode.

Its clock system integrates ECO (4–33 MHz) with PLL for 48 MHz core clock, WCO (32 kHz), IMO (±2%), and ILO (40 kHz), enabling precise timing for motor control quadrature decoding and LIN slave communication via SCBs. The CAN FD block supports data rates up to 5 Mbps with protocol-level error handling.

FAQ

What is the maximum operating frequency of the Arm® Cortex®-M0+ core in CY8C4148AZAS585XQLA1?

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 supported by the Read Accelerator to eliminate flash wait states during instruction fetch.

Does CY8C4148AZAS585XQLA1 support CAN FD with ISO 11898-1:2015 compliance?

Yes, the integrated CAN FD controller supports data rates up to 5 Mbps and complies with ISO 11898-1:2015 physical layer timing requirements when paired with a certified CAN FD transceiver. It includes CRC-17 for classic frames and CRC-21 for FD frames, plus automatic retransmission and error confinement features.

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

All 84 programmable GPIO pins support CAPSENSE™ sensing. The Multi-Sense Converter (MSC) achieves a typical minimum detectable finger capacitance of 0.1 pF with >5:1 signal-to-noise ratio under wet conditions, enabled by SmartSense auto-tuning and hardware-accelerated baseline tracking.

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

No, the SAR ADC performs sequential sampling using its built-in channel sequencer, but supports hardware-triggered acquisition (e.g., from TCPWM or SCB events) and on-the-fly averaging across up to 64 samples per channel. Simultaneous sampling requires external analog multiplexing or discrete ADCs.
