Infineon Technologies MB96F673ABPMC1-GSE1

Overview

MB96F673ABPMC1-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 GPIOs, and on-chip voltage regulator supporting 2.7V–5.5V operation. It delivers 32MHz CPU frequency via internal PLL (×8 from 4MHz resonator), 31.2ns instruction cycle, and operates in automotive-grade temperature range (−40°C to +105°C) for motor control and body electronics.

For engineers reviewing the MB96F673ABPMC1-GSE1 datasheet, MB96F673ABPMC1-GSE1 pinout, MB96F673ABPMC1-GSE1 application, or MB96F673ABPMC1-GSE1 equivalent, key selection criteria include CAN protocol compliance (ISO16845), dual-bank Flash for safe firmware updates, stepping motor controller with two synchronized 8/10-bit PWM channels, RTC with clock calibration, and hardware watchdog with window function.

Technical Context

The MB96F673ABPMC1-GSE1 implements the F2MC-16FX RISC-like architecture with 8-byte instruction queue, signed multiply/divide instructions, and 23 addressing modes optimized for real-time embedded control. Its clock tree supports independent domain selection: CPU (up to 32MHz via PLL), peripherals (via main/sub/RC clocks), and subsystems like RTC (32.768kHz) and LIN (with automatic header handling).

It integrates dedicated hardware accelerators including a stepping motor controller with high-current drivers, 4-channel 16-bit PPG with timing point capture, and 3-channel 16-bit reload timers with event counting. The CAN module provides 32 message objects, programmable FIFO mode, loop-back self-test, and disabled auto-retransmission for time-triggered operation.

FAQ

What is the maximum operating frequency of the MB96F673ABPMC1-GSE1 CPU?

The CPU achieves up to 32MHz using the internal PLL configured for ×8 multiplication from a 4MHz external resonator. This yields a minimum instruction cycle time of 31.2ns. The PLL supports selectable multipliers (×1 to ×8), and the device also accepts direct external clock inputs up to 8MHz when the fast clock input feature is enabled.

Does the MB96F673ABPMC1-GSE1 support LIN communication?

No - the MB96F673ABPMC1-GSE1 variant includes one LIN-capable USART (LIN-USART 0), but it lacks the second LIN-USART channel found in the MB96F675ABPMC1-GSE1. It supports LIN 2.0A/B as master or slave with automatic header transmission/reception and 16-byte RX/TX FIFO, reducing CPU interrupt load during protocol handling.

How does the stepping motor controller interface with external drivers?

The integrated stepping motor controller (SMC) provides two independent channels (SMC0/SMC1), each with four high-current outputs and two synchronized 8/10-bit PWM generators. It uses a dedicated power supply pin (VSMC) and supports internal prescaling (1, 1/4, 1/5, ..., 1/16) for PWM clock derivation - eliminating need for external gate drivers in low-to-mid power applications.

Is the Flash memory protected against unauthorized access?

Yes - the device implements Flash Security to prevent unintended read-out of program memory contents. Protection is enforced via configuration bits in the Boot ROM and requires specific unlock sequences. Additionally, low-voltage detection during Flash erase/write operations prevents corruption under brown-out conditions, and sector protection allows selective locking of memory regions.
