Product details
Overview
CY8C4148AZAS578XQLA1 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 running at 48 MHz, featuring 384 KB flash, 32 KB SRAM, 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 requiring integrated analog sensing, motor PWM control, and fault-tolerant communication.
For engineers reviewing the CY8C4148AZAS578XQLA1 datasheet, CY8C4148AZAS578XQLA1 pinout, CY8C4148AZAS578XQLA1 application, or CY8C4148AZAS578XQLA1 equivalent, key selection factors include CAN FD timing compliance, Deep Sleep current (2.5 µA), programmable analog routing, MSC water-tolerance capability, and ModusToolbox™ API support for CAPSENSE™ tuning.
Technical Context
The device integrates a single-layer AHB-Lite interconnect linking the Cortex-M0+ core, 5 reconfigurable Serial Communication Blocks (SCBs), and 8 TCPWM blocks supporting center-aligned PWM with comparator-triggered kill signals-critical for motor drive safety. Its analog subsystem includes two opamps operable in Deep Sleep mode and a dedicated MSC block with hardware-accelerated SmartSense auto-tuning.
Clock architecture combines a 4–33 MHz ECO with PLL for 48 MHz system clock, a 32-kHz WCO for RTC, and ±2% IMO for fast wake-up. Cryptographic acceleration covers AES, SHA, TRNG, and CRC-enabling secure boot and firmware authentication in automotive ECUs.

FAQ
What is the maximum operating temperature grade for CY8C4148AZAS578XQLA1?
This part is qualified to AEC-Q100 Grade-S, with guaranteed operation from –40°C to +105°C ambient temperature. It uses automotive-grade packaging and die attach materials validated for 15-year lifetime under thermal cycling stress per JESD22-A104. The on-die temperature sensor is factory-calibrated across this full range and accessible via the SAR ADC interface.
Does CY8C4148AZAS578XQLA1 support CAN FD physical layer compliance?
Yes - it integrates a CAN FD controller compliant with ISO 11898-1:2015, supporting data rates up to 5 Mbps in FD mode and standard CAN 2.0B at 1 Mbps. The transceiver is external; however, the controller provides bit-timing registers, CRC-17/21 calculation, and flexible message RAM configuration required for physical layer interoperability testing.
Can the MSC block operate reliably with water overlay on the touch surface?
Yes - the Multi-Sense Converter (MSC) block achieves >5:1 signal-to-noise ratio under water overlay conditions, verified per IEC 61000-4-6 and automotive splash testing standards. SmartSense auto-tuning dynamically adjusts baseline and threshold parameters using internal reference channels, maintaining false-touch immunity without manual recalibration.
Is ModusToolbox™ required to configure the programmable analog blocks?
No - while ModusToolbox™ provides GUI-based configuration and validated Peripheral Driver Libraries (PDL), all analog blocks (CTBm, SAR ADC, MSC) can be configured directly via memory-mapped registers per the register TRM. However, PDL usage is strongly recommended for ASIL-B development due to pre-verified initialization sequences and runtime error-checking routines.
