It operates at up to 16.25 MHz machine clock using external clock input and targets embedded motor control and industrial sensing applications.

For engineers reviewing the MB95F398HPMC1-G-SNE2 datasheet, MB95F398HPMC1-G-SNE2 pinout, MB95F398HPMC1-G-SNE2 application, or MB95F398HPMC1-G-SNE2 equivalent, key selection criteria include Flash size (60 KB), ADC resolution flexibility (8/10-bit), LIN-UART dual-mode operation, MPG waveform sequencing capability, and LQFP-48 package compatibility with FPT-48P-M49 footprint.

Technical Context

The MB95F398HPMC1-G-SNE2 implements the F2MC-8FX CPU core with 136 instructions, 1–3 byte encoding, and hardware support for multiplication/division and bit manipulation. It supports multiple clock sources: external clock (≤32.5 MHz), main OSC (≤16.25 MHz), and main CR (1/8/10/12.5 MHz ±2% in LQFP), enabling precise timing control across operating modes.

Peripheral integration includes a dedicated multi-pulse generator (MPG) with 16-bit reload timer, 16-bit PPG timer, event counter, and waveform sequencer - all optimized for closed-loop DC motor drive. The LIN-UART channel supports both clock-synchronous and clock-asynchronous serial transfer, configurable as LIN master or slave, with programmable baud rate generation.

FAQ

What clock sources does the MB95F398HPMC1-G-SNE2 support?

The device supports three main clock sources: external crystal/ceramic (X0/X1, up to 16.25 MHz), external clock input (up to 32.5 MHz), and on-chip main CR oscillator (1/8/10/12.5 MHz, ±2% accuracy in LQFP). A separate subclock domain includes 32.768 kHz sub-OSC, 32.768 kHz external clock, or 50–200 kHz sub-CR oscillator for RTC and low-power wake-up.

Does MB95F398HPMC1-G-SNE2 support LIN 2.x protocol natively?

Yes - the integrated LIN-UART peripheral supports LIN 2.2-compliant frame formatting, checksum calculation (classic/enhanced), auto-sync detection, and identifier filtering. It operates as either LIN master or slave without external transceiver, using internal pull-up/pull-down and slew-rate control on dedicated LIN pins.

How many analog input channels are available, and what resolutions do they support?

The device integrates a single 12-channel SAR ADC supporting both 8-bit and 10-bit conversion resolution per channel. Resolution is selected per conversion group via control register bits, allowing mixed-precision sampling - e.g., 10-bit for temperature sensing and 8-bit for fast-switching status monitoring - within one ADC module.

Is on-chip debug supported, and what interface does it use?

Yes - on-chip debug is implemented via a 1-wire serial interface on pin P12/DBG. It supports asynchronous serial programming, real-time register inspection, and breakpoint execution without requiring additional pins or external debug adapters beyond a simple level-shifter circuit per the MB95390H hardware manual.
