Infineon Technologies MB96F647RBPMC-GSE2

Overview

MB96F647RBPMC-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, 64 KB RAM, CAN 2.0A/B interface, and integrated A/D converter with 10-bit resolution. It operates from 2.7 V to 5.5 V and supports 13 low-power modes for automotive body control modules requiring real-time CAN messaging and sensor interfacing.

For engineers reviewing the MB96F647RBPMC-GSE2 datasheet, MB96F647RBPMC-GSE2 pinout, MB96F647RBPMC-GSE2 application, or MB96F647RBPMC-GSE2 equivalent, key selection criteria include its ISO16845-certified CAN controller with 32 message objects, dual-bank flash enabling concurrent read/erase, on-chip voltage regulator for wide supply tolerance, and one-wire OCD debug interface supporting hardware breakpoints and trace.

Technical Context

The MB96F647RBPMC-GSE2 implements the F2MC-16FX architecture with an 8-byte instruction queue, barrel shifter, and signed multiply/divide instructions-enabling deterministic execution for real-time control. Its clock tree decouples CPU (up to 32 MHz) and peripheral domains, allowing independent frequency selection from main oscillator (4–8 MHz), subclock (32.768 kHz), or internal RC (100 kHz/2 MHz).

It integrates a hardware watchdog with window function, three independent source clock timers (23-/23-/17-bit), and a quadrature position/revolution counter (QPRC) with configurable edge detection on AIN/BIN/ZIN pins-supporting precise motor position sensing without external logic.

FAQ

Does MB96F647RBPMC-GSE2 support CAN FD?

No. The device implements ISO11898-1:2015 CAN 2.0A/B protocol only, with bit rates up to 1 Mbps and 32 message objects. It does not support CAN FD frame format, data rate switching, or extended data length. For CAN FD applications, consider Infineon's AURIX™ TC3xx family.

What is the maximum operating temperature range for this MCU?

The MB96F647RBPMC-GSE2 is rated for industrial temperature range: –40 °C to +85 °C ambient. It is not qualified for automotive AEC-Q100 Grade 1 (–40 °C to +125 °C) or Grade 0. Thermal derating applies above 70 °C ambient when operating at maximum CPU frequency and peripheral load.

Can the internal RC oscillator be used as the main system clock?

Yes-the 100 kHz or 2 MHz internal RC oscillator can serve as the main clock source, enabling fast wake-up from Stop mode (<10 µs). However, it lacks the accuracy required for CAN bit timing or RTC; the subclock (32.768 kHz quartz) must be used for timekeeping, and external resonator is required for full-speed CAN operation.

Is the flash memory protected against unauthorized read-out?

Yes. The device includes Flash Security features that prevent external read-out via serial programming interface when enabled. Protection is activated by setting specific bits in the ROM configuration block during programming; once secured, only erase-and-reprogram cycles clear the protection-no backdoor access exists.
