Technical Context

The MB96F338USAPMC-GS-N2K5E2 implements the F2MC-16FX CPU core with instruction pipeline for RISC-like performance and full backward compatibility with 16LX software. Its clock system integrates an on-chip PLL (×1–×25), 32–100 kHz sub-oscillator, and 100 kHz/2 MHz internal RC oscillator-enabling independent clock domain selection for CPU and peripherals.

It features three independent CAN controllers (ISO16845 certified, up to 1 Mbit/s), eight full-duplex USARTs supporting LIN master/slave operation, and a 36-channel 10-bit SAR ADC with external trigger capability via reload timer. The device includes 10-channel DMA, 16-bit programmable pulse generator (PPG), and alarm comparator with dual thresholds.

FAQ

What boot modes are supported by MB96F338USAPMC-GS-N2K5E2?

The device supports ROM boot (mask ROM execution), Flash boot (user code from internal Flash), and serial programming mode. Boot configuration is determined by MD0–MD2 pin states at power-on reset. Flash boot is default for this part number; ROM boot requires external mask ROM and specific MD pin strapping.

Does MB96F338USAPMC-GS-N2K5E2 support Time-Triggered CAN (TTCAN)?

Yes-it supports TTCAN via the Disabled Automatic Retransmission mode, allowing deterministic message scheduling. Each CAN channel provides programmable FIFO and identifier masking, and the 32-message object buffer enables precise time-slot allocation for synchronized node operation in distributed automotive systems.

How is Flash security implemented on this MCU?

Flash security is enforced through hardware lock bits that disable external read access via serial programming interface and prevent debug access to Flash contents. Once enabled, security cannot be disabled without erasing the entire Flash array. Security status is readable via dedicated status register but write-protection is irreversible.

What are the power supply requirements for AVCC/AVSS and digital VCC/VSS?

AVCC and AVSS must be supplied with clean 3.3 V ±5% analog power, decoupled with 100 nF ceramic capacitors near the pins. Digital VCC/VSS operate at same nominal voltage but require separate 10 µF + 100 nF decoupling. AVRH/AVRL define ADC reference range (typically AVCC/AVSS or external); internal regulator supplies core logic at reduced voltage for EMI suppression.
