Infineon Technologies CY8C4148AZSS565XQLA1

Overview

CY8C4148AZSS565XQLA1 from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-qualified PSoC™ 4100S Max microcontroller based on the Arm® Cortex®-M0+ CPU running at 48 MHz, featuring 384 KB flash, 32 KB SRAM, integrated CAN FD (up to 5 Mbps), 12-bit 1-Msps SAR ADC, and multi-sense capacitive sensing (MSC) with >5:1 SNR. It targets body control modules, smart sensors, and automotive HMI interfaces.

For engineers reviewing the CY8C4148AZSS565XQLA1 datasheet, CY8C4148AZSS565XQLA1 pinout, CY8C4148AZSS565XQLA1 application, or CY8C4148AZSS565XQLA1 equivalent, key selection criteria include CAN FD timing compliance, Deep Sleep current (2.5 µA), CAPSENSE™ water tolerance, and reconfigurable SCB peripherals supporting I²C/SPI/UART/LIN in runtime.

Technical Context

The device integrates a single-layer AHB-Lite interconnect linking the Cortex-M0+ core, 5x Serial Communication Blocks (SCBs), and CAN FD controller - all operating under synchronized clock domains derived from ECO+PLL (48 MHz) or WCO (32 kHz). Its analog subsystem includes two CTBm opamps with Deep Sleep operation and ADC input buffering, plus dual low-power comparators active in <2.5 µA system state.

Digital flexibility is enabled by programmable Smart I/O logic, eight TCPWM blocks supporting quadrature decoding and kill-signal triggering, and hardware-accelerated cryptography (AES, SHA, TRNG, CRC). The MSC block implements hardware-based capacitive sensing with automatic SmartSense tuning and >5:1 signal-to-noise ratio independent of firmware calibration.

FAQ

What is the maximum CAN FD bit rate supported by CY8C4148AZSS565XQLA1?

The device supports CAN FD up to 5 Mbps in data phase, compliant with ISO 11898-1:2015. This requires external CAN transceiver matching the physical layer specification and proper PCB layout for signal integrity. Bit timing registers are fully programmable via the CAN FD block configuration API in ModusToolbox™.

Does CY8C4148AZSS565XQLA1 include a built-in temperature sensor?

Yes - a calibrated temperature sensor is integrated within the 12-bit SAR ADC subsystem, delivering ±0.5°C accuracy from –40°C to +105°C. It shares the ADC's reference and conversion path, enabling direct readout without external components or calibration coefficients.

Can all GPIO pins be used for CAPSENSE™ sensing simultaneously?

No - while any GPIO pin can be assigned to CAPSENSE™, the MSC block supports up to 32 simultaneous sensing channels. Pin allocation is constrained by port grouping and routing resources; full 84-pin CAPSENSE™ operation is not physically possible due to internal analog bus limitations.

Is external crystal required for CAN FD operation?

No - CAN FD timing derives from the internal PLL clock (48 MHz), which can be sourced from either the 4–33 MHz external crystal oscillator (ECO) or the ±2% internal main oscillator (IMO). For production-grade timing accuracy, Infineon recommends ECO + PLL; IMO is acceptable for non-critical baud rates.
