Product details
Overview
CY8C4149AZA-S598 from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-grade PSoC™ 4100S Max microcontroller based on Arm® Cortex®-M0+ CPU, featuring 48 MHz operation, 384 KB flash, 32 KB SRAM, CAN FD up to 5 Mbps, and integrated CAPSENSE™ with SmartSense auto-tuning. It serves as a reconfigurable system-on-chip for body control modules requiring robust capacitive sensing, motor PWM control, and LIN/CAN communication.
For engineers reviewing the CY8C4149AZA-S598 datasheet, CY8C4149AZA-S598 pinout, CY8C4149AZA-S598 application, or CY8C4149AZA-S598 equivalent, key selection criteria include its 84 GPIO count with analog/digital/CAPSENSE™ flexibility, Deep Sleep current of 2.5 µA with active analog, 12-bit 1-Msps SAR ADC with temperature sensor, and hardware crypto acceleration for AES/SHA/TRNG in safety-critical automotive designs.
Technical Context
The device integrates a single-layer AHB-Lite interconnect linking Cortex-M0+ core, flash/SRAM controllers, and peripherals including five reconfigurable Serial Communication Blocks (SCBs), eight TCPWM blocks supporting quadrature decoding and kill-signal triggering, and dual opamps operable in Deep Sleep mode. Its programmable analog subsystem includes CTBm blocks with high-drive external and high-bandwidth internal modes, plus SAR ADC input buffering.
The CAN FD block operates at up to 5 Mbps with dedicated message RAM and filtering logic, while the MSC block delivers >5:1 SNR for wet-finger tolerant capacitive touch. Clocking supports ECO (4–33 MHz) + PLL for 48 MHz, WCO (32 kHz), IMO (±2%), and ILO (40 kHz), enabling precise timing across sleep/wake transitions.

FAQ
What is the maximum operating temperature grade for CY8C4149AZA-S598?
CY8C4149AZA-S598 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 1.5 of AEC-Q100 Rev-H and applies to the full 100-pin TQFP package variant. Thermal derating is not required within this range for standard PCB layouts with 2 oz copper and 4 thermal vias per power pad.
Does CY8C4149AZA-S598 support CAN FD with ISO 11898-1:2015 compliance?
Yes, the integrated CAN FD controller complies with ISO 11898-1:2015 for physical layer signaling and ISO 11898-2:2016 for high-speed CAN transceiver interface timing. It supports data rates up to 5 Mbps in FD mode, automatic bit-rate switching, and CRC-17/21 error detection. The controller includes 64 message objects with hardware acceptance filtering and timestamping aligned to system clock.
Can all 84 GPIOs be used simultaneously for CAPSENSE™ sensing?
No - while any GPIO can be configured for CAPSENSE™, the Multi-Sense Converter (MSC) block supports up to 32 simultaneous sensing channels per scan. Full 84-pin utilization requires time-multiplexed scanning across multiple groups, managed by the MSC sequencer. SmartSense auto-calibration adjusts baseline and thresholds per channel, maintaining >5:1 SNR even with sequential scanning.
Is ModusToolbox™ required to develop firmware for CY8C4149AZA-S598?
No, ModusToolbox™ is optional but strongly recommended. The device supports Arm® GCC, IAR Embedded Workbench, and Keil MDK toolchains via CMSIS-Pack. However, ModusToolbox™ provides validated Peripheral Driver Libraries (PDL) for TCPWM, SCB, and MSC, plus CAPSENSE™ Tuner GUI and SmartSense configuration - reducing bring-up time from weeks to days for production-ready touch and communication firmware.
