FAQ

What is the maximum operating frequency of the MB95F108AWPMC1-G-JNE1?

The device achieves a maximum system clock of 20 MHz using its internal PLL, derived from a 1–10 MHz external crystal. This frequency is fully supported across the full −40°C to +85°C temperature range and 2.7–5.5 V supply voltage, with no derating required for timing-critical motor control loops.

Does the MB95F108AWPMC1-G-JNE1 support in-system programming (ISP)?

Yes-it supports ISP via single-wire debug (SWD) interface using standard tools such as Infineon's DAS-Link debugger. Firmware updates can be performed without removing the chip from the PCB, and flash sectors can be individually erased and reprogrammed while preserving calibration data in protected memory regions.

Is there hardware support for functional safety compliance (e.g., IEC 61508 SIL2)?

The MCU includes several safety-oriented features: windowed watchdog timer, parity-protected RAM, flash CRC generator, and BOD with hysteresis. While not pre-certified, these features align with IEC 61508 requirements for systematic capability and hardware fault tolerance in SIL2-targeted designs.

Can the integrated PGA be used with external sensors like thermistors or strain gauges?

Yes-the PGA offers programmable gain settings (1×, 2×, 4×, 8×, 16×, 32×, 64×, 128×) and connects directly to ADC input channels PA0–PA7. It supports rail-to-rail input common-mode range and is optimized for low-noise DC-coupled measurements typical of precision temperature and pressure sensing.
