Infineon Technologies MB9BF318TPMC-GK7E1

Overview

MB9BF318TPMC-GK7E1 from Infineon Technologies (formerly Cypress) is a 32-bit ARM® Cortex®-M3 microcontroller with 1 MB Flash, 128 KB SRAM, USB 2.0 Full-Speed device/host interface, 32-channel 12-bit ADC (1.0 μs conversion), and motor control peripherals including QPRC, multi-function timers, and PWM. It operates at up to 144 MHz and supports 2.7–5.5 V supply for industrial motor control and embedded automation.

For engineers reviewing the MB9BF318TPMC-GK7E1 datasheet, MB9BF318TPMC-GK7E1 pinout, MB9BF318TPMC-GK7E1 application, or MB9BF318TPMC-GK7E1 equivalent, key selection criteria include Flash/SRAM size, USB dual-role capability, real-time motor timing features (QPRC + DTIF), 144 MHz Cortex-M3 performance, and 5 V-tolerant I/O support in LQFP-176 package.

Technical Context

This MCU implements the ARM Cortex-M3 r2p1 core with Memory Protection Unit (MPU) and NVIC supporting 48 peripheral interrupts across 16 priority levels. Its clock system integrates five sources - main oscillator (4–48 MHz), sub-clock (32.768 kHz), two internal CR oscillators, and Main PLL - with Clock Supervisor (CSV) for external clock failure detection.

The peripheral set targets real-time motion control: three Multi-function Timers provide PWM, dead-time insertion, A/D activation triggers, and DTIF emergency stop; three QPRC units track encoder position/revolution with configurable AIN/BIN/ZIN edge detection; and dual USB channels support simultaneous device and host roles with 256-byte packet handling and automatic connect/disconnect detection.

FAQ

What debug interfaces does MB9BF318TPMC-GK7E1 support?

It supports Serial Wire JTAG Debug Port (SWJ-DP) with Embedded Trace Macrocell (ETM) for real-time instruction tracing and non-intrusive debugging. No SWD-only or cJTAG variants are supported - full JTAG boundary scan and SWD are both enabled via the same 5-pin header. Debug access remains functional across all power modes except STOP.

Does MB9BF318TPMC-GK7E1 include a hardware USB PHY?

Yes - it integrates a full-speed USB 2.0 PHY compliant with USB specification rev 2.0. Both USB channels (0 and 1) include differential DP/DM pins, internal termination resistors, and voltage regulators for USBVCC domains. No external PHY or transceiver is required for basic device or host operation.

How many independent 16-bit timers support dead-time insertion for motor control?

Three Multi-function Timer units each provide dedicated dead-time insertion logic for complementary PWM outputs. Each unit supports up to six output compare channels with programmable dead-time delay (1–255 clock cycles), enabling precise gate driver control for 3-phase inverters without CPU intervention.

Is the 12-bit ADC capable of simultaneous sampling across multiple channels?

No - the three 12-bit ADC units operate independently and do not support hardware-synchronized start. However, they support priority-based scanning with shared trigger sources (e.g., timer match, QPRC overflow), allowing tightly coordinated sampling sequences with ≤100 ns skew between units when triggered by the same event.
