Infineon Technologies CY8C4148AZAS565XQLA1

Overview

CY8C4148AZAS565XQLA1 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, operating at up to 48 MHz. It integrates 384 KB flash, 32 KB SRAM, a 12-bit 1-Msps SAR ADC, two opamps with Deep Sleep support, and a CAN FD controller supporting up to 5 Mbps - deployed in automotive body control modules for capacitive touch sensing and motor PWM control.

For engineers reviewing the CY8C4148AZAS565XQLA1 datasheet, CY8C4148AZAS565XQLA1 pinout, CY8C4148AZAS565XQLA1 application, or CY8C4148AZAS565XQLA1 equivalent, key selection criteria include CAN FD timing compliance, CAPSENSE™ SNR (>5:1), Deep Sleep current (2.5 µA), TCPWM kill-signal triggering, and 84-GPIO reconfigurability across analog/digital/CAPSENSE™ domains.

Technical Context

The device implements a single-layer AHB-Lite interconnect linking the Cortex-M0+ core, memory subsystem (384 KB flash + 32 KB SRAM), and programmable peripherals including five reconfigurable Serial Communication Blocks (SCBs) and eight TCPWM blocks. Its analog subsystem features dual CTBm opamps with ADC input buffering and comparator modes, plus a dedicated Multi-Sense Converter (MSC) block optimized for high-SNR capacitive sensing under wet conditions.

Digital flexibility is enabled by Smart I/O logic blocks for Boolean port-level operations and hardware-accelerated cryptography (AES, SHA, TRNG, CRC). Clocking includes ECO (4–33 MHz) + PLL for 48 MHz system clock, WCO (32 kHz), and low-power ILO (40 kHz), all supporting deterministic wake-up from Deep Sleep mode with active analog retention.

FAQ

What is the maximum operating temperature grade for CY8C4148AZAS565XQLA1?

CY8C4148AZAS565XQLA1 is qualified to AEC-Q100 Grade-S, supporting continuous operation from –40°C to +105°C ambient temperature. This rating is verified per stress-test conditions defined in the qualification report, and applies to the full 100-pin TQFP package variant with specified thermal derating curves in the datasheet's "Thermal Characteristics" section.

Does CY8C4148AZAS565XQLA1 support CAN FD with ISO 11898-1:2015 compliance?

Yes - the integrated CAN FD controller supports bit rates up to 5 Mbps in FD mode and complies with ISO 11898-1:2015 physical layer timing requirements when paired with a compliant transceiver. The device implements automatic bit-rate switching, CRC-17/21, and flexible data-length payloads (up to 64 bytes), as confirmed in the "CAN FD Block" functional description and electrical specifications sections of Rev. *G datasheet.

Can all 84 GPIOs be used simultaneously for CAPSENSE™ sensing?

No - while all 84 GPIOs are CAPSENSE™-capable, simultaneous use is constrained by MSC hardware resources: the Multi-Sense Converter supports up to 32 sensing channels per scan, with sequential scanning enabling full 84-pin coverage across multiple frames. Channel count per scan depends on resolution, averaging, and scan speed settings, as detailed in the "CAPSENSE™ Block Specifications" table (Section 7.3.5) of the datasheet.

Is ModusToolbox™ required for development with CY8C4148AZAS565XQLA1?

ModusToolbox™ is the recommended and fully supported IDE, providing PDL-based APIs, CAPSENSE™ Tuner, and SmartSense configuration tools. However, the device is compatible with Arm®-compliant toolchains (e.g., GCC ARM Embedded, Keil MDK) using CMSIS definitions and startup files provided in the official PSoC™ 4 Peripheral Driver Library - no vendor lock-in is enforced at the compiler or debugger level.
