Infineon Technologies CY8C4148AZES578XQLA1

Overview

CY8C4148AZES578XQLA1 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 and in-vehicle human-machine interface systems requiring robust touch sensing and real-time communication.

For engineers reviewing the CY8C4148AZES578XQLA1 datasheet, CY8C4148AZES578XQLA1 pinout, CY8C4148AZES578XQLA1 application, or CY8C4148AZES578XQLA1 equivalent, key selection considerations include CAN FD timing compliance, Deep Sleep current (2.5 µA), MSC water-tolerance capability, programmable analog opamp modes, and GPIO reconfigurability across CAPSENSE™/ADC/digital functions.

Technical Context

The device implements a tightly coupled system-on-chip architecture with a single-layer AHB-Lite interconnect linking the Cortex-M0+ core, memory subsystem (384 KB flash + 32 KB SRAM), and heterogeneous peripherals. Its analog subsystem includes two reconfigurable CTBm opamps supporting high-drive external and high-bandwidth internal modes, plus two low-power comparators operational in Deep Sleep mode.

Digital flexibility is enabled by five runtime-reconfigurable Serial Communication Blocks (SCBs) supporting I²C/SPI/UART/LIN, eight 16-bit TCPWM blocks with quadrature decode and comparator-triggered kill signals, and a dedicated CAN FD controller compliant with ISO 11898-1:2015 for data rates up to 5 Mbps.

FAQ

What is the maximum operating temperature grade for CY8C4148AZES578XQLA1?

CY8C4148AZES578XQLA1 is qualified to AEC-Q100 Grade-S, supporting continuous operation from –40°C to +105°C ambient temperature. This rating is verified per test condition 2.5 of the AEC-Q100 standard and applies to the full 100-pin TQFP package variant with specified thermal derating curves in the datasheet's Section 7.2.1.

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

Yes, CY8C4148AZES578XQLA1 includes a dedicated CAN FD controller compliant with ISO 11898-1:2015, supporting bit rates up to 5 Mbps in FD mode and full backward compatibility with classical CAN 2.0B. The implementation includes hardware message filtering, FIFO buffering, and error confinement logic as documented in Section 4.6 of the datasheet.

Can the SAR ADC operate during Deep Sleep mode?

No, the 12-bit SAR ADC requires Active or Sleep mode to function; it is disabled in Deep Sleep mode. However, the two low-power comparators and temperature sensor remain operational in Deep Sleep, enabling wake-up event detection without full CPU activation - a capability confirmed in Section 4.3.3 and Table 7-10 of the datasheet.

Is ModusToolbox™ required for development with this MCU?

ModusToolbox™ is the recommended and fully supported IDE for CY8C4148AZES578XQLA1, providing PDL-based peripheral drivers, CAPSENSE™ Tuner, and SmartSense configuration tools. While Arm-compatible toolchains (e.g., GCC + OpenOCD) can be used, only ModusToolbox™ delivers validated HAL integration, automated clock tree configuration, and MSC hardware tuning workflows per Infineon Application Note AN229347.
