Overview

MB95F398KPMC1-G-SNE2 from Cypress Semiconductor is an 8-bit F2MC-8FX microcontroller in the MB95390H series, featuring 60 KB Flash, 2032 bytes RAM, 45 I/O ports (41 CMOS + 4 N-ch open-drain), and dual-bank Flash for concurrent read/erase. It integrates LIN-UART, I²C, UART/SIO, 12-channel 8/10-bit ADC, multi-pulse generator for DC motor control, and hardware/software watchdog timers. Used in automotive body control modules requiring deterministic timing and mixed-signal integration.

For engineers reviewing the MB95F398KPMC1-G-SNE2 datasheet, MB95F398KPMC1-G-SNE2 pinout, MB95F398KPMC1-G-SNE2 application, or MB95F398KPMC1-G-SNE2 equivalent, key selection criteria include LIN master/slave capability, 16.25 MHz max machine clock with external clock input, 45-pin LQFP package (FPT-52P-M02), and on-chip debug via 1-wire serial interface.

Technical Context

The MB95F398KPMC1-G-SNE2 implements the F2MC-8FX CPU core with 136 instructions, 1–3 byte encoding, and support for 16-bit arithmetic, multiplication/division, and bit manipulation. Its clock system allows independent selection of main clock sources (up to 32.5 MHz external, 16.25 MHz machine clock) and subclocks (32.768 kHz or 100 kHz sub-CR).

Peripheral architecture includes a multi-pulse generator (MPG) with dedicated 16-bit PPG and reload timer, waveform sequencer with compare-clear function, and LIN-UART supporting both asynchronous (UART) and synchronous (SIO) modes plus LIN protocol framing. The 12-channel ADC supports selectable 8/10-bit resolution with programmable input voltage level (CMOS/hysteresis).

FAQ

What is the maximum operating frequency supported by MB95F398KPMC1-G-SNE2?

The device supports a maximum external clock input of 32.5 MHz, yielding a maximum machine clock frequency of 16.25 MHz. This is achieved using the external clock source mode, and corresponds to a minimum instruction execution time of 61.5 ns. The main OSC clock option is limited to 16.25 MHz input (8.125 MHz machine clock), while the main CR clock offers up to 12.5 MHz machine clock with ±2% or ±2.5% accuracy depending on package type.

Does MB95F398KPMC1-G-SNE2 support LIN 2.2 protocol compliance?

Yes - the integrated LIN-UART supports both LIN master and slave operation with configurable baud rates, break detection, sync field handling, and identifier-based frame transmission. It meets LIN 2.2 physical layer requirements when paired with a compliant LIN transceiver (e.g., TLE7259-3GE), and includes built-in wake-up functionality via dominant timeout detection on the LIN bus line.

How many analog input channels can be simultaneously sampled?

The 12-channel 8/10-bit ADC supports sequential scanning of all channels in a single conversion sequence, but does not support true simultaneous sampling. Conversion time per channel is 16 µs (at 1 MHz ADC clock), and the scan mode allows automatic sequencing across selected channels with interrupt-on-completion. External sample-and-hold circuitry is required for synchronized multi-channel acquisition.

Is on-chip debug supported in all low-power modes?

No - on-chip debug via 1-wire serial interface remains active only in normal and sleep modes. Debug functionality is disabled in stop mode, watch mode, and time-base timer mode to ensure lowest possible current draw. To re-enable debug, the device must be woken via external interrupt, reset, or watchdog timeout, after which the debug interface resumes operation upon exit from the low-power state.
