Infineon Technologies MB96F637RBPMC-GSE2

Overview

MB96F637RBPMC-GSE2 from Infineon Technologies (formerly Cypress) is a 16-bit F2MC-16FX microcontroller featuring a 32 MHz CPU clock (via PLL ×8 from 4–8 MHz resonator), 512 KB on-chip flash, 32 KB RAM, integrated CAN 2.0A/B controller (ISO16845 certified, up to 1 Mbps), and 10-bit SAR ADC with 24 channels. It operates from 2.7 V to 5.5 V and supports 13 low-power modes, targeting automotive body control modules and industrial motor control systems.

For engineers reviewing the MB96F637RBPMC-GSE2 datasheet, MB96F637RBPMC-GSE2 pinout, MB96F637RBPMC-GSE2 application, or MB96F637RBPMC-GSE2 equivalent, key selection criteria include its dual-bank flash for safe firmware updates, hardware watchdog with window function, QPRC for encoder interfacing, LIN/SCI/USART coexistence, and subclock RTC with calibration-critical for deterministic real-time embedded control.

Technical Context

The MB96F637RBPMC-GSE2 implements the F2MC-16FX CPU core with 8-byte instruction queue, barrel shifter, and signed 16×16 multiply/32÷16 divide instructions. Its clock tree enables independent domain configuration: CPU driven by PLL-multiplied main clock (up to 32 MHz), peripherals selectable from main, sub (32.768 kHz), or RC (100 kHz/2 MHz) sources.

It integrates a full CAN 2.0B controller with 32 message objects, programmable FIFO mode, loop-back self-test, and disabled automatic retransmission for time-triggered operation. The A/D converter supports scan disable, range comparator, and external trigger via PPG or reload timers-enabling synchronized sampling in motor current sensing.

Key Specifications

FAQ

Does MB96F637RBPMC-GSE2 support CAN FD?

No. MB96F637RBPMC-GSE2 implements only classical CAN 2.0A/B protocol with bit rates up to 1 Mbps and 32 message objects. It does not support CAN FD frame format, data rate switching, or extended payload length. For CAN FD, consider Infineon's newer AURIX™ TC3xx series or RA6T2 from Renesas.

What is the maximum operating temperature for this MCU?

The MB96F637RBPMC-GSE2 is rated for industrial temperature range: –40 °C to +85 °C ambient. It meets AEC-Q100 Grade 2 qualification when operated within recommended voltage (2.7–5.5 V) and clock (≤32 MHz) limits. Thermal derating is not required below 85 °C ambient with standard PCB copper pour.

Can the on-chip debugger (OCD) be used in production firmware?

Yes-the built-in one-wire OCD interface remains functional post-programming and supports non-intrusive trace (42 branches), hardware breakpoints (6 points), and execution time measurement. However, flash security lock disables OCD access unless enabled via ROM configuration block during boot, preserving IP protection in deployed units.

Is the 32.768 kHz RTC oscillator supported with external crystal only?

No. The subclock oscillator supports both external 32.768 kHz quartz crystals and internal RC oscillation (100 kHz/2 MHz). When using the RC source, the RTC retains timekeeping during main power loss if VBAT is supplied, and clock calibration corrects drift against the main oscillator-enabling ±1 ppm accuracy without external crystal.
