Infineon Technologies MB96F673RBPMC1-GSE1

Overview

MB96F673RBPMC1-GSE1 from Infineon Technologies (formerly Cypress) is a 16-bit F2MC-16FX microcontroller with integrated CAN 2.0A/B interface, 12-channel 8/10-bit SAR ADC, dual-operation Flash (128.5KB + 32KB), 48–50 GPIO, and on-chip voltage regulator supporting 2.7V–5.5V operation. It delivers 32MHz CPU speed via internal PLL (×8 from 4–8MHz resonator), 31.2ns min instruction cycle, and operates in 13 low-power modes for automotive body control and industrial motor management.

For engineers reviewing the MB96F673RBPMC1-GSE1 datasheet, MB96F673RBPMC1-GSE1 pinout, MB96F673RBPMC1-GSE1 application, or MB96F673RBPMC1-GSE1 equivalent, key selection criteria include CAN protocol compliance (ISO16845), dual-bank Flash for seamless firmware updates, stepping motor controller with two synchronized 8/10-bit PWMs per channel, and hardware watchdog with window function for safety-critical embedded systems.

Technical Context

The MB96F673RBPMC1-GSE1 implements the F2MC-16FX RISC-like architecture with 8-byte instruction queue, signed multiply/divide instructions, and 23 addressing modes-enabling direct migration from F2MC-16LX software. Its clock tree supports independent domain selection: CPU from PLL/main oscillator (up to 32MHz), peripherals from main/sub/RC clocks, and RTC from 32.768kHz crystal or RC source.

Peripheral integration includes a dedicated stepping motor controller with four high-current outputs per channel, programmable pulse generators (4×16-bit or 8×8-bit) with timing-point capture and ADC trigger capability, and LIN-capable USARTs with automatic header handling. The on-chip debugger uses one-wire interface with 6 hardware breakpoints and 42-branch trace depth for real-time firmware validation.

FAQ

What is the maximum operating temperature range for MB96F673RBPMC1-GSE1?

The MB96F673RBPMC1-GSE1 is rated for industrial temperature range: –40°C to +85°C ambient. This is confirmed in Section 14.2 ("Recommended Operating Conditions") of the official datasheet (Document Number 002-04703 Rev. *D), where Vcc = 2.7V–5.5V and all DC/AC characteristics are specified across this range.

Does this MCU support JTAG debugging?

No-MB96F673RBPMC1-GSE1 uses a proprietary one-wire On-Chip Debugger (OCD) interface, not JTAG. The OCD supports hardware breakpoints, trace, and event sequencing via a single dedicated debug pin (DEBUG), as detailed in Section 11 ("Interrupt Vector Table") and Section 13.13 ("Mode Pin (MD)") of the datasheet.

Can the internal PLL be disabled after startup to reduce EMI?

Yes-the PLL can be stopped dynamically via software control of the PLL stop bit (PLLS bit in the PLL Control Register). When stopped, the CPU switches to the main oscillator or RC clock source, reducing switching noise and improving EMI behavior during low-activity periods, as described in Section 13.4 ("Notes on PLL Clock Mode Operation").

Is the stepping motor controller capable of microstepping?

No-the integrated Stepping Motor Controller (SMC) supports only full-step and half-step excitation modes using its four high-current outputs per channel. Microstepping requires external indexer or current-controlled drivers; the SMC provides fixed-current phase sequencing without current DAC or chopper control circuitry, per Section 1 ("Product Lineup") and block diagram on page 6.
