Infineon Technologies MB96F673RBPMC-GSE1

Overview

MB96F673RBPMC-GSE1 from Infineon Technologies (formerly Cypress) is a 16-bit F2MC-16FX microcontroller with integrated CAN 2.0B interface, 128.5KB Flash + 32KB RAM, 12-channel 8/10-bit SAR ADC, and dual-clock domain operation. It features an on-chip PLL enabling up to 32MHz CPU frequency from a 4–8MHz external resonator, 32 message object CAN controller, and stepping motor control with two synchronized PWM channels per channel. Used in automotive body control modules requiring real-time CAN communication and motor actuation.

For engineers reviewing the MB96F673RBPMC-GSE1 datasheet, MB96F673RBPMC-GSE1 pinout, MB96F673RBPMC-GSE1 application, or MB96F673RBPMC-GSE1 equivalent, key selection criteria include CAN protocol compliance (ISO 16845), dual-bank Flash for concurrent read/erase, sub-31.2ns instruction cycle time, and integrated stepping motor driver with dedicated high-current outputs and bias supply.

Technical Context

The MB96F673RBPMC-GSE1 implements the F2MC-16FX RISC-like architecture with 8-byte instruction queue, signed multiply/divide instructions, and 23 addressing modes optimized for embedded control. Its clock system supports independent domain configuration: CPU clock derived from PLL-multiplied main oscillator (up to 32MHz), while peripherals select from main, sub (32.768kHz), or RC (100kHz/2MHz) sources.

It integrates a full CAN 2.0B controller with 32 configurable message objects, programmable FIFO mode, loop-back self-test, and disabled automatic retransmission for time-triggered operation. The stepping motor controller includes two independent channels, each with four high-current outputs, dual 8/10-bit PWMs, and dedicated AVcc supply for analog/motor drive isolation.

FAQ

What is the maximum operating frequency and corresponding instruction cycle time?

The MB96F673RBPMC-GSE1 achieves a maximum CPU frequency of 32MHz using its on-chip PLL with a 4–8MHz external resonator. At this speed, the minimum instruction cycle time is 31.2ns, verified in AC Characteristics section (Table 14.4) of Infineon's Document 002-04703 Rev. *D. This timing is guaranteed across the full industrial temperature range (−40°C to +85°C) and supply voltage (2.7V–5.5V).

Does this MCU support time-triggered CAN communication?

Yes. The CAN controller supports time-triggered operation via the Disabled Automatic Retransmission mode, which prevents spontaneous retransmission after error frames - a mandatory feature for deterministic scheduling in time-triggered networks. Configuration is performed through CAN control registers (CANCR and CANMCR), and the mode is explicitly documented in Section 10.3.3 of the datasheet.

How is the stepping motor controller powered and isolated?

The stepping motor controller uses a dedicated AVcc pin (Pin 59) supplied separately from the main Vcc. This allows independent filtering and regulation to suppress motor switching noise from affecting analog peripherals (ADC, RTC, subclock). The datasheet specifies AVcc must be decoupled with ≥10µF low-ESR capacitor and maintained within 2.7V–5.5V, matching Vcc tolerance.

Is the on-chip debugger compatible with standard JTAG tools?

No. The MB96F673RBPMC-GSE1 uses a proprietary one-wire debug interface (OCD) compliant with Cypress/Infineon's MiniProg3 and KitProg2 debug probes. It does not support IEEE 1149.1 JTAG. Debug access requires Infineon's PSoC Programmer or ModusToolbox IDE with appropriate debug adapter firmware, as specified in Section 11 (Interrupt Vector Table) and Appendix A of the reference manual.
