Infineon Technologies MB9BF416SPMC-GK7E1

Overview

MB9BF416SPMC-GK7E1 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller designed for motor control and industrial embedded systems. It operates up to 144 MHz, integrates 1 MB Flash and 128 KB SRAM (64 KB SRAM0 + 64 KB SRAM1), supports dual CAN 2.0A/B interfaces at 1 Mbps, and includes 32-channel 12-bit ADC with 1.0 μs conversion time at 5 V.

For engineers reviewing the MB9BF416SPMC-GK7E1 datasheet, MB9BF416SPMC-GK7E1 pinout, MB9BF416SPMC-GK7E1 application, or MB9BF416SPMC-GK7E1 equivalent, key selection considerations include its dual-CAN capability, motor-specific peripherals (QPRC, multi-function timers with dead-time control), 5 V-tolerant I/O support, and SWJ-DP debug interface with ETM trace.

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 combines five sources - including 4–48 MHz main oscillator, 32.768 kHz sub-clock, and Main PLL - with Clock Supervisor (CSV) for external clock failure detection.

The peripheral set targets real-time motion control: three QPRC units for encoder position tracking, three multi-function timers with A/D activation and DTIF emergency stop, and eight DMA channels operating on an independent bus to offload CPU during high-bandwidth transfers (e.g., ADC-to-memory, CAN message buffering).

Key Specifications

Pinout & Package

MB9BF416SPMC-GK7E1 is housed in a 176-pin LQFP package (24 × 24 mm, 0.5 mm pitch) with 154 fast I/O ports, including 5 V-tolerant pins as specified in the "List of Pin Functions" (Document 002-04689 Rev. *F, Section 4.2). The package supports full external bus interface (8 chip selects, 25-bit address, 8/16-bit data) and dedicated motor control signals (e.g., QPRC inputs AIN/BIN/ZIN, PWM outputs, DTIF).

FAQ

Does MB9BF416SPMC-GK7E1 support CAN FD?

No. MB9BF416SPMC-GK7E1 implements CAN 2.0A/B only, with maximum bit rate of 1 Mbps and standard 11-bit identifier support. It does not include CAN FD features such as flexible data-rate switching, extended data length (up to 64 bytes), or CRC separation. For CAN FD, consider Infineon's newer AURIX™ TC3xx series.

What is the maximum operating temperature range for this device?

MB9BF416SPMC-GK7E1 is rated for industrial temperature range: –40 °C to +85 °C ambient. This is confirmed in Section 12.2 ("Recommended Operating Conditions") of the datasheet (Document 002-04689 Rev. *F), with voltage supply requirements tightened at temperature extremes (e.g., VCC min = 2.85 V at +85 °C).

Is the on-chip Flash memory protected against unauthorized readout?

Yes. The device includes a security function for code protection, allowing configuration of Flash lock bits to disable readout via debug interface (SWJ-DP) and prevent extraction of firmware. This feature is documented in the "On-chip Memories" section and implemented via dedicated Flash control registers accessible only in privileged mode.

Can the external bus interface operate in NAND Flash mode with hardware ECC?

No. While the external bus interface supports NAND Flash devices, it does not integrate hardware ECC logic. NAND interfacing requires external ECC handling - either via software (e.g., BCH algorithm in bootloader) or companion controller. The interface provides timing control and address/data multiplexing but no on-die error correction engine.
