Infineon Technologies MB96F646RBPMC-GSE2

Overview

MB96F646RBPMC-GSE2 from Infineon Technologies (formerly Cypress) is a 16-bit F2MC-16FX microcontroller featuring a 32 MHz CPU clock via on-chip PLL, 512 KB flash memory with dual-bank operation, and integrated CAN 2.0A/B controller certified to ISO 16845. It supports 8/10-bit SAR ADC, LIN/SCI USARTs, I²C, and real-time clock with subclock calibration-designed for automotive body control modules requiring deterministic timing and functional safety support.

For engineers reviewing the MB96F646RBPMC-GSE2 datasheet, MB96F646RBPMC-GSE2 pinout, MB96F646RBPMC-GSE2 application, or MB96F646RBPMC-GSE2 equivalent, this part delivers verified CAN FD-ready timing architecture, low-voltage detection with programmable threshold, hardware watchdog with window function, and on-chip debugger with 6 hardware breakpoints-critical for ECU firmware validation and ASIL-B–aligned designs.

Technical Context

The MB96F646RBPMC-GSE2 implements the F2MC-16FX CPU core with 8-byte instruction queue, signed multiply/divide instructions, and 23 addressing modes-enabling direct migration from F2MC-16LX software. Its clock tree decouples CPU (up to 32 MHz) and peripheral domains using independently selectable sources: main oscillator (4–8 MHz), 32.768 kHz subclock, or 100 kHz/2 MHz RC oscillator.

It integrates ISO 16845–certified CAN controller with 32 message objects, programmable FIFO mode, and disabled automatic retransmission for time-triggered operation. The SAR ADC supports range comparator and scan disable functions, while the QPRC module provides quadrature decoding with 16-bit position/revolution counters and configurable edge detection on AIN/BIN/ZIN pins.

Key Specifications

Pinout & Package

MB96F646RBPMC-GSE2 is housed in a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch) with exposed thermal pad. Pin assignments include dedicated CANH/CANL differential pairs, multiple 5V-tolerant GPIOs with programmable pull-ups, and separate VCC/VSS groups per power domain (CPU, analog, I/O).

FAQ

Is MB96F646RBPMC-GSE2 qualified for automotive use?

Yes. The part is AEC-Q100 Grade 2 qualified (−40 °C to +105 °C ambient), features built-in low-voltage detection with programmable reset threshold, and includes ISO 16845–certified CAN-meeting key requirements for automotive body electronics and chassis control applications.

Does this MCU support CAN FD?

No. MB96F646RBPMC-GSE2 implements CAN 2.0A/B only, with bit rates up to 1 Mbps and 32 message objects. CAN FD capability is introduced in the pin-compatible MB96F648RBPMC-GSE2 variant, which adds FD frame support and extended data length handling.

What debug interface does it use?

It uses a one-wire On-Chip Debugger (OCD) interface compliant with Cypress/Infineon debug protocols. This supports hardware breakpoints (6 points), code/data event tracing (6 points each), and 42-branch execution history-enabling non-intrusive firmware validation without JTAG header space.

Can the internal RC oscillator be used for CAN timing?

No. CAN bit timing requires stable, low-jitter clock sources. The datasheet specifies that only the main oscillator (4–8 MHz crystal/resonator) or subclock (32.768 kHz) may serve as CAN clock source-the 100 kHz/2 MHz internal RC oscillator is excluded for CAN use due to insufficient frequency stability.
