Infineon Technologies CY8C4148AZES558XQLA1

Overview

CY8C4148AZES558XQLA1 from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-grade PSoC™ 4100S Max microcontroller featuring a 48-MHz Arm® Cortex®-M0+ CPU, 384 KB flash, 32 KB SRAM, integrated CAN FD (up to 5 Mbps), and CAPSENSE™ multi-sense converter for high-SNR capacitive touch. It targets body control modules, smart sensors, and automotive HMI systems requiring reconfigurable analog/digital peripherals and deep-sleep operation at 2.5 µA.

For engineers reviewing the CY8C4148AZES558XQLA1 datasheet, CY8C4148AZES558XQLA1 pinout, CY8C4148AZES558XQLA1 application, or CY8C4148AZES558XQLA1 equivalent, key selection criteria include CAN FD timing compliance, Deep Sleep current with active analog, SAR ADC resolution and sampling rate, MSC SNR performance, and GPIO flexibility for mixed-signal routing in constrained automotive PCB layouts.

Technical Context

The device implements a single-layer AHB-Lite interconnect linking the Cortex-M0+ core, memory subsystem (384 KB flash with Read Accelerator, 32 KB SRAM), and programmable peripherals including five reconfigurable Serial Communication Blocks (SCBs), eight TCPWM units, and dual opamps with Deep Sleep support. Clocking includes ECO (4–33 MHz) + PLL for 48 MHz, WCO (32 kHz), IMO (±2%), and ILO (40 kHz).

Analog subsystem integrates a 12-bit 1-Msps SAR ADC with temperature sensor, two low-power comparators, CTBm opamps supporting ADC input buffering and comparator modes, and MSC block enabling >5:1 SNR capacitive sensing with SmartSense auto-tuning. Digital logic includes Smart I/O and programmable Boolean logic on port pins.

FAQ

What is the maximum operating temperature range for CY8C4148AZES558XQLA1?

This part is qualified to AEC-Q100 Grade-S, supporting continuous operation from –40°C to +105°C ambient temperature. It maintains full electrical specifications across this range, including CAN FD timing compliance and SAR ADC accuracy, validated per JEDEC JESD22-A108F thermal cycling and JESD22-A104E temperature humidity bias testing.

Does CY8C4148AZES558XQLA1 support hardware-based cryptographic operations?

Yes - it includes a dedicated Crypto block with AES-128/256 encryption/decryption, SHA-256 hashing, True Random Number Generation (TRNG), and CRC-32 acceleration. These functions operate independently of the CPU, enabling secure boot, firmware authentication, and encrypted CAN FD message payloads without compromising real-time task scheduling.

Can the SAR ADC perform simultaneous sampling on multiple channels?

No - the 12-bit SAR ADC uses a single conversion engine with a channel sequencer and supports sequential sampling at up to 1 Msps aggregate rate. It does not implement true simultaneous sampling across channels, but signal averaging and programmable trigger sources (TCPWM, SCB, or software) allow deterministic multi-channel acquisition aligned to system events.

Is CAN FD bus timing fully compliant with ISO 11898-1:2015 at 5 Mbps?

Yes - the integrated CAN FD controller meets ISO 11898-1:2015 physical layer timing requirements for data phase bit rates up to 5 Mbps, including sample point positioning, propagation delay compensation, and synchronization jump width configuration. Validation includes loopback and bus stress testing under worst-case voltage/temperature conditions.
