Infineon Technologies CY8C4149AZI-S598

Overview

CY8C4149AZI-S598 from Infineon is a PSoC™ 4100S Max programmable system-on-chip MCU based on the Arm® Cortex®-M0+ CPU, operating at up to 48 MHz, with 384 KB flash, 32 KB SRAM, and integrated capacitive sensing (CAPSENSE™), CAN FD, and cryptographic acceleration (AES/SHA/TRNG). It serves as a reconfigurable embedded controller for human-interface, motor control, and industrial sensing applications.

For engineers reviewing the CY8C4149AZI-S598 datasheet, CY8C4149AZI-S598 pinout, CY8C4149AZI-S598 application, or CY8C4149AZI-S598 equivalent, key selection criteria include its Deep Sleep current (3.7 µA), dual MSC capacitive sensing converters with >5:1 SNR, CAN FD support, 12-bit 1-Msps SAR ADC with temperature sensor, and 84 GPIOs in 100-pin TQFP package.

Technical Context

The device integrates an Arm® Cortex®-M0+ core with single-cycle multiply, coupled with programmable analog blocks (two opamps, two low-power comparators, 12-bit SAR ADC) and digital resources including eight TCPWM blocks, five reconfigurable SCBs (I2C/SPI/UART), and Smart I/O logic. Its clock system combines ECO (4–33 MHz), WCO (32 kHz), IMO (±2%), and PLL for precise timing.

Capacitive sensing is implemented via two autonomous Multi-Sensing Converters (MSC) supporting liquid-tolerant scanning without CPU intervention, while the cryptographic block delivers hardware-accelerated AES, SHA, TRNG, PRNG, and CRC - enabling secure boot and data integrity in edge-connected devices.

FAQ

Does CY8C4149AZI-S598 support CAN FD physical layer compliance?

Yes. The device integrates a CAN FD controller compliant with ISO 11898-1:2015, supporting data rates up to 5 Mbps and payloads up to 64 bytes. It requires an external CAN transceiver (e.g., Infineon TLE9251VS) for physical layer signaling, and the SCB peripheral is configured in CAN FD mode via PDL APIs.

What is the maximum operating temperature range for this part?

CY8C4149AZI-S598 is rated for industrial temperature range: –40 °C to +85 °C ambient. This is confirmed in Section 5.2 of the datasheet (002-30372 Rev. *F), with thermal derating applied above 70 °C under sustained 48-MHz operation and full peripheral load.

Can the on-chip opamps drive external loads directly?

Yes - each of the two continuous-time opamps supports external drive capability up to ±25 mA at unity gain, with rail-to-rail output swing. They operate in Deep Sleep mode and can buffer ADC inputs or drive small actuators, but require external compensation for stability with capacitive loads >100 pF.

Is ModusToolbox™ software required to develop for this MCU?

No. While ModusToolbox™ is Infineon's recommended IDE with CAPSENSE™ middleware and PDL libraries, the device is fully compatible with Arm® GCC toolchains, Keil MDK, and IAR Embedded Workbench. Debugging works via standard SWD interface using any CMSIS-DAP-compliant probe.
