Infineon Technologies MB96F6B6RBPMC-GSE2

Overview

MB96F6B6RBPMC-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 16-channel input. It operates from 2.7 V to 5.5 V and supports 13 low-power modes, targeting automotive body control modules requiring real-time communication and mixed-signal processing.

For engineers reviewing the MB96F6B6RBPMC-GSE2 datasheet, MB96F6B6RBPMC-GSE2 pinout, MB96F6B6RBPMC-GSE2 application, or MB96F6B6RBPMC-GSE2 equivalent, key selection criteria include CAN protocol compliance, dual-bank flash for safe firmware updates, sub-31.2 ns instruction cycle time, on-chip voltage regulator for wide supply tolerance, and integrated LCD controller supporting 4COM × 36SEG.

Technical Context

The device implements the F2MC-16FX RISC-like architecture with an 8-byte instruction queue, barrel shifter, and hardware-signed multiply/divide (16×16/32÷16). Its clock tree decouples CPU and peripheral domains, enabling independent frequency selection from main oscillator (4–8 MHz), subclock (32.768 kHz), or internal RC (100 kHz/2 MHz).

System-level features include ISO16845-certified CAN with 32 message objects, programmable FIFO mode, and disabled automatic retransmission for time-triggered operation; plus dual-operation flash allowing concurrent read/program-erase across two banks under DMA control.

Key Specifications

Pinout & Package

MB96F6B6RBPMC-GSE2 is housed in a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch) with exposed thermal pad. Pin functions are validated per CY966B0 Series datasheet Rev. *D, pages 8–11.

FAQ

Does MB96F6B6RBPMC-GSE2 support CAN FD?

No. This device implements only classical CAN 2.0A/B protocol with bit rates up to 1 Mbps and ISO16845 certification. It does not include CAN FD frame format support, arbitration bit rate extension, or flexible data-length payload handling. For CAN FD requirements, consider Infineon's newer AURIX™ TC3xx family.

What debug interface does MB96F6B6RBPMC-GSE2 use?

It uses a one-wire On-Chip Debugger (OCD) interface compliant with Cypress's proprietary protocol. This requires the CY8CKIT-002 MiniProg3 or compatible programmer/debugger. JTAG is not supported; SWD is also unavailable. Breakpoints, trace, and event sequencing are accessible exclusively through the OCD pin (TCK/DEBUG).

Is the internal RC oscillator accurate enough for RTC operation?

The 100 kHz/2 MHz internal RC oscillator is not suitable for standalone RTC timing due to ±10% initial tolerance and temperature drift. However, the device supports clock calibration using the 32.768 kHz subclock oscillator - which can be trimmed via register writes to correct for crystal deviation, achieving ±5 ppm accuracy after calibration.

Can the LCD controller drive segment-based displays without external bias resistors?

Yes. The on-chip LCD controller supports internal voltage generation with selectable duty cycles (1/2, 1/3, 1/4) and fixed 1/3 bias. Internal divider resistors eliminate the need for external components when driving up to 4COM × 36SEG displays, though external resistors may be used for fine-tuning contrast or higher COM counts.
