FAQ

What is the maximum operating frequency of the Arm® Cortex®-M0+ core in CY8C4148AZAS568XQLA1?

The Arm® Cortex®-M0+ core operates at a maximum frequency of 48 MHz, achieved via internal PLL multiplication of the external crystal oscillator (ECO) or internal main oscillator (IMO). This frequency is fully supported across all operating voltage ranges (1.71 V to 5.5 V) and temperature grades, including Grade-S (–40°C to +105°C), and is validated per AEC-Q100 stress test conditions.

Does CY8C4148AZAS568XQLA1 support CAN FD with ISO 11898-1:2015 compliance?

Yes, CY8C4148AZAS568XQLA1 integrates a dedicated CAN FD controller compliant with ISO 11898-1:2015, supporting data rates up to 5 Mbps in FD mode and full backward compatibility with classical CAN 2.0B. The block operates independently of the CPU, includes hardware message filtering, and supports flexible data length up to 64 bytes per frame.

Can all 84 GPIO pins be used simultaneously for CAPSENSE™ sensing?

No - while all 84 GPIO pins are *capable* of CAPSENSE™ functionality, the Multi-Sense Converter (MSC) block supports up to 32 simultaneous sensing channels in a single scan. Channel allocation is managed by the SmartSense auto-tuning engine, and physical pin assignment must respect analog routing constraints and mutual capacitance limits defined in the device's IOSS architecture.

Is the 12-bit SAR ADC equipped with hardware averaging and temperature sensing?

Yes, the 12-bit SAR ADC includes a built-in temperature sensor and supports hardware-accelerated signal averaging across up to 64 samples per channel. Averaging is performed in the ADC sequencer engine without CPU intervention, reducing noise in battery voltage or cabin temperature measurements while maintaining low power consumption in Active or Deep Sleep modes.
