It integrates LIN-UART, CAN 2.0B, and I²C interfaces, and features a 10-bit ADC with 16 channels. Designed for automotive body electronics and industrial control systems requiring robust serial communication and real-time peripheral response.

For engineers reviewing the MB95F652LNPFT-G-SNE2 datasheet, MB95F652LNPFT-G-SNE2 pinout, MB95F652LNPFT-G-SNE2 application, or MB95F652LNPFT-G-SNE2 equivalent, this device supports AEC-Q100 Grade 2 qualification, on-chip debug via single-pin interface, and mixed-signal integration for cost-sensitive embedded control where CAN/LIN coexistence and low-pin-count packaging are critical.

Technical Context

The MB95F652LNPFT-G-SNE2 implements the F2MC-8FX 8-bit CISC architecture optimized for instruction-per-cycle efficiency in real-time control tasks. It includes dual CAN 2.0B controllers with message objects and FIFO support, plus a dedicated LIN-UART module compliant with LIN 2.2A and SAE J2602.

On-chip analog functions include a 10-bit successive-approximation ADC with hardware-triggered sampling and scan mode, alongside programmable voltage detection (PVD) and low-voltage detection (LVD) circuits for system-level power monitoring and fail-safe operation.

FAQ

What is the maximum operating temperature range for MB95F652LNPFT-G-SNE2?

The MB95F652LNPFT-G-SNE2 is qualified to AEC-Q100 Grade 2, supporting continuous operation from −40°C to +105°C ambient temperature. This rating covers junction temperatures under typical automotive under-hood and cabin mounting conditions with standard PCB copper pour and airflow assumptions.

Does MB95F652LNPFT-G-SNE2 support CAN FD?

No, MB95F652LNPFT-G-SNE2 implements CAN 2.0B only, with fixed 11-bit identifiers and up to 8-byte payload per frame. It does not support CAN FD's extended data length or flexible bit-rate switching. For CAN FD applications, consider Infineon's TRAVEO™ T2G or FM4 families instead.

Can the LIN-UART operate simultaneously with both CAN controllers?

Yes, the LIN-UART and dual CAN controllers operate independently using separate clock domains and interrupt vectors. All three serial interfaces can be active concurrently-e.g., LIN for sensor polling, CAN0 for body domain messaging, and CAN1 for gateway forwarding-without resource contention or timing conflict.

Is there a recommended external crystal frequency for CAN timing accuracy?

A 16.000 MHz crystal is recommended for optimal CAN bit timing accuracy across all supported baud rates (125 kbps to 1 Mbps). This frequency yields integer divisors for CAN prescalers and minimizes residual timing error in the CAN bit segment calculation per ISO 11898-1.
