FAQ
What is the maximum operating frequency of the Arm® Cortex®-M0+ core in CY8C4148AZAS595XQLA1?
The Arm® Cortex®-M0+ core operates at a maximum frequency of 48 MHz, achieved via internal PLL multiplication from the 4–33 MHz external crystal oscillator (ECO) or ±2% internal main oscillator (IMO). This frequency is fully supported across the full Grade-S temperature range (–40°C to +105°C) and all voltage supply modes (1.71–5.5 V).
Does CY8C4148AZAS595XQLA1 support CAN FD with ISO 11898-1:2015 compliance?
Yes, the integrated CAN FD block supports data rates up to 5 Mbps and complies with ISO 11898-1:2015. It includes bit-rate switching, flexible data-length frames (up to 64 bytes), and built-in error confinement logic. No external transceiver is required for physical layer interfacing - only standard CANH/CANL termination and biasing.
How many GPIO pins support CAPSENSE™ functionality?
All 84 GPIO pins are CAPSENSE™-capable via the Multi-Sense Converter (MSC) block. Each pin can be configured as a sensor electrode or shield, with hardware-accelerated scanning, noise filtering, and automatic SmartSense tuning - no software polling or calibration routines required for baseline operation.
Is ModusToolbox™ required to develop firmware for this device?
No, ModusToolbox™ is recommended but not mandatory. The device supports industry-standard Arm® toolchains including GCC, Keil MDK, and IAR Embedded Workbench. Peripheral Driver Libraries (PDL) and HAL APIs are provided in source form, enabling integration with custom build systems and CI/CD pipelines used in automotive software development.
