Infineon Technologies MB9BF518TPMC-GK7E1

Overview

MB9BF518TPMC-GK7E1 from Infineon Technologies (formerly Cypress) is a 32-bit ARM® Cortex®-M3 microcontroller with 1 MB Flash, 128 KB SRAM, dual CAN 2.0B interfaces, USB 2.0 Full-Speed device/host support, and 32-channel 12-bit ADC. It operates up to 144 MHz, includes MPU, NVIC with 48 peripheral interrupts, and targets motor control and industrial embedded systems.

For engineers reviewing the MB9BF518TPMC-GK7E1 datasheet, MB9BF518TPMC-GK7E1 pinout, MB9BF518TPMC-GK7E1 application, or MB9BF518TPMC-GK7E1 equivalent, key selection criteria include dual CAN timing compliance, USB host/device endpoint configuration, Flash accelerator performance at >72 MHz, and QPRC encoder interface capability for real-time position feedback.

Technical Context

This MCU implements the ARM Cortex-M3 r2p1 core with Memory Protection Unit (MPU) and integrated NVIC supporting 16 priority levels and 48 peripheral interrupts. Its clock system combines five sources - main oscillator (4–48 MHz), sub-clock (32.768 kHz), high-speed/low-speed internal CR oscillators, and Main PLL - enabling dynamic switching and robust clock supervision.

The peripheral set is optimized for motion control: dual CAN controllers (1 Mbps, 32 message buffers), three multi-function timers with dead-time insertion and DTIF interrupt, three QPRC units (16-bit position/revolution counters), and base timers configurable as PWM, PPG, or reload timers - all synchronized to shared clock domains and accessible via DMA channels.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency and how is it achieved?

The MB9BF518TPMC-GK7E1 achieves up to 144 MHz core frequency using the Main PLL with an external crystal (4–48 MHz) as input. The Flash accelerator enables zero-wait-state execution up to 72 MHz; above that, the accelerator maintains deterministic access timing without CPU stalls, verified across temperature and voltage ranges per datasheet AC characteristics.

Does this MCU support USB device and host simultaneously?

Yes - it integrates two independent USB controllers: USB ch.0 operates as a Full-Speed device (6 endpoints, double-buffered), while USB ch.1 functions as a Full/Low-Speed host with automatic device connect/disconnect detection and 256-byte packet support. Both operate concurrently without shared resources or clock domain contention.

How many encoder interfaces does it provide and what resolution do they support?

It includes three independent Quadrature Position/Revolution Counters (QPRC), each with 16-bit position and revolution counters, configurable AIN/BIN/ZIN edge detection, and two 16-bit compare registers. Each QPRC supports standard quadrature decoding and index pulse capture for absolute position tracking in motor and actuator applications.

Is the part qualified for automotive applications?

Yes - the MB9BF518TPMC-GK7E1 is manufactured under Infineon's automotive quality管理体系, conforms to AEC-Q100 Grade 2 (−40°C to +105°C), and includes features required for automotive use: dual-stage LVD, clock supervisor, hardware watchdog with CR oscillator backup, and CAN 2.0B compliance for body electronics and chassis subsystems.
