Infineon Technologies MB96F636RBPMC-GSE2

Overview

MB96F636RBPMC-GSE2 from Infineon Technologies (formerly Cypress) is a 16-bit F2MC-16FX microcontroller featuring CAN 2.0A/B compliance, 32 MHz CPU operation via on-chip PLL, 128 KB flash, 8 KB RAM, and integrated voltage regulator supporting 2.7–5.5 V supply. It delivers 31.2 ns instruction cycle time and operates in automotive-grade temperature range (−40°C to +105°C). Used in vehicle body control modules requiring real-time CAN messaging and low-power sleep modes.

For engineers reviewing the MB96F636RBPMC-GSE2 datasheet, MB96F636RBPMC-GSE2 pinout, MB96F636RBPMC-GSE2 application, or MB96F636RBPMC-GSE2 equivalent, key selection criteria include CAN bit rate up to 1 Mbps, dual-bank flash for safe firmware updates, 32 message objects with individual identifier masks, and support for Time-Triggered CAN via disabled automatic retransmission mode.

Technical Context

The MB96F636RBPMC-GSE2 implements the F2MC-16FX CPU core with 8-byte instruction queue, barrel shifter, and signed multiply/divide instructions. Its clock system integrates a programmable PLL (×1 to ×8), 4–8 MHz main oscillator, 32.768 kHz subclock, and 100 kHz/2 MHz RC oscillator - all independently selectable per CPU and two peripheral domains.

Peripheral integration includes ISO16845-certified CAN controller with 32 message objects, four USARTs supporting LIN master/slave, I²C up to 400 kbps, 10-bit SAR ADC with range comparator, QPRC for motor position sensing, and hardware watchdog with window function. Power management supports 13 operating modes including Timer Stop and Deep Sleep with wake-up via CAN RX or USART SIN.

FAQ

What is the maximum allowed crystal frequency for the main oscillator?

The MB96F636RBPMC-GSE2 supports a 4 MHz to 8 MHz ceramic resonator or quartz crystal on the XIN/XOUT pins. When using a ceramic resonator, maximum frequency depends on Q-factor; quartz crystals up to 8 MHz are fully supported with standard load capacitance (12–20 pF) and startup time under 10 ms.

Does this MCU support LIN 2.1 protocol natively?

Yes - the integrated USARTs support LIN 2.1 physical layer signaling and protocol framing when configured in LIN mode. The hardware includes automatic sync-break detection, checksum calculation (classic/enhanced), and slave node response timing control, eliminating software overhead for LIN frame handling.

How many CAN message objects can be configured for FIFO mode?

Up to 32 message objects can be concatenated into a single FIFO structure. Each object retains its own identifier mask and acceptance filtering; the FIFO operates with automatic head/tail pointer management and interrupt generation upon buffer full or empty conditions.

Is the on-chip voltage regulator adjustable for different core voltages?

No - the internal voltage regulator is fixed-output and supplies the CPU core at ~1.8 V from a 2.7–5.5 V VCC input. It is not user-adjustable but automatically engages during all operating modes, including deep sleep, to maintain stable core voltage and minimize leakage current.
