Infineon Technologies CY8C4149LDSS583XQLA1

Overview

CY8C4149LDSS583XQLA1 from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-qualified 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 multi-sense capacitive sensing (MSC) with >5:1 SNR. It supports CAPSENSE™, LCD segment drive, and five reconfigurable Serial Communication Blocks (SCBs) for I²C/SPI/UART/LIN in body control modules.

For engineers reviewing the CY8C4149LDSS583XQLA1 datasheet, CY8C4149LDSS583XQLA1 pinout, CY8C4149LDSS583XQLA1 application, or CY8C4149LDSS583XQLA1 equivalent, key selection factors include CAN FD compliance, Deep Sleep current (2.5 µA), programmable analog (2 opamps + 12-bit 1-Msps SAR ADC), and 84 GPIO with CAPSENSE™/LCD/analog/digital reconfiguration capability.

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 peripherals including CAN FD, five SCBs, eight TCPWM blocks, and dual CTBm opamps with Deep Sleep operation. Clocking includes ECO (4–33 MHz), PLL (48 MHz), WCO (32 kHz), IMO (±2%), and ILO (40 kHz).

Analog resources integrate a 12-bit SAR ADC with channel sequencer and signal averaging, two low-power comparators active in Deep Sleep, and MSC block supporting hardware-accelerated SmartSense tuning. Digital flexibility includes Smart I/O logic, programmable GPIO drive modes, and DMA-driven data movement across peripherals.

FAQ

What is the maximum operating temperature range for CY8C4149LDSS583XQLA1?

This part is qualified to AEC-Q100 Grade-S, with guaranteed operation from –40°C to +105°C ambient temperature. It includes an on-die temperature sensor integrated into the SAR ADC subsystem, calibrated for ±2.5°C accuracy across this full range, and usable for thermal monitoring in engine bay or dashboard-mounted ECUs.

Does CY8C4149LDSS583XQLA1 support CAN FD with ISO 11898-1:2015 compliance?

Yes. The integrated CAN FD controller complies with ISO 11898-1:2015 and supports bit rates up to 5 Mbps in FD mode, including flexible data-length payloads (up to 64 bytes), CRC-17/21 error detection, and automatic protocol arbitration. It operates independently of CPU load using dedicated DMA channels for transmit/receive buffers.

Can the 12-bit SAR ADC perform simultaneous sampling across multiple channels?

No. The SAR ADC uses a single conversion core with a hardware channel sequencer that supports automated round-robin scanning of up to 16 inputs, including signal averaging over up to 64 samples per channel. Simultaneous sampling requires external synchronized ADCs; this device achieves effective multi-channel acquisition through deterministic sequencing and DMA-triggered result storage.

Is ModusToolbox™ required to configure the programmable analog blocks?

No. While ModusToolbox™ provides graphical configuration and auto-generated PDL code for CTBm opamps, comparators, and ADC, all analog blocks can be fully controlled via direct register writes using the documented register map in the TRM. Hardware behavior (e.g., opamp gain settings, comparator hysteresis) is defined by fixed register bits-not firmware abstraction layers.
