Product details
Overview
MB9BF116SPMC-GE1 from Cypress Semiconductor (now Infineon) is a 32-bit ARM® Cortex®-M3 microcontroller in the FM3 family, designed for motor control and industrial embedded applications. It operates up to 144 MHz, integrates 1 MB Flash and 128 KB SRAM (64 KB SRAM0 + 64 KB SRAM1), supports LIN 2.1, UART, I²C, and CSIO interfaces, and features 32-channel 12-bit ADC with 1.0 μs conversion time at 5 V.
For engineers reviewing the MB9BF116SPMC-GE1 datasheet, MB9BF116SPMC-GE1 pinout, MB9BF116SPMC-GE1 application, or MB9BF116SPMC-GE1 equivalent, key selection criteria include its dual watchdog architecture (hardware + software), QPRC encoder interface support, CRC accelerator for CCITT CRC16/IEEE-802.3 CRC32, and 176-pin LQFP package with 154 fast I/O ports - critical for real-time motor control and industrial HMI designs.
Technical Context
The MB9BF116SPMC-GE1 implements the ARM Cortex-M3 r2p1 core with Memory Protection Unit (MPU) and NVIC supporting 48 peripheral interrupts across 16 priority levels. Its on-chip memory subsystem includes separate I-code/D-code bus-connected SRAM0 and system-bus-connected SRAM1, enabling concurrent CPU and DMA access without contention.
Peripheral integration targets deterministic real-time control: Base Timers support 16-bit PWM/PPG/reload modes; Multi-function Timers provide input capture, A/D activation compare, and waveform generation; QPRC units accept quadrature A/B/Z inputs with configurable edge detection and dual 16-bit counters for position/revolution tracking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-M3 r2p1, up to 144 MHz - enables hard real-time task scheduling with sub-μs interrupt latency. |
| Flash Memory | 1 MB with Flash Accelerator and 16 KB trace buffer - eliminates wait states up to 72 MHz; sustains high-speed code execution above that via accelerator. |
| SRAM | 128 KB total (64 KB SRAM0 + 64 KB SRAM1) - SRAM0 serves instruction/data cache paths; SRAM1 handles DMA-accessed buffers and peripherals. |
| A/D Converter | 32-channel, 12-bit SAR ADC, 1.0 μs @ 5 V - supports high-resolution analog sensing with scan/priority modes and FIFO buffering. |
| Communication | Up to 8 serial channels (UART/CSIO/LIN/I²C), LIN 2.1 compliant - enables multi-node automotive body control and industrial fieldbus interfacing. |
| Timers & Counters | 16 Base Timer channels, 3 Multi-function Timers, 3 QPRC units - delivers synchronized PWM generation, encoder feedback, and motor emergency stop (DTIF) capability. |
| Power Supply | 2.7 V to 5.5 V operation - allows direct interfacing with 3.3 V and 5 V logic systems without level-shifting. |
Pinout & Package
MB9BF116SPMC-GE1 is housed in a 176-pin LQFP (24 × 24 mm, 0.5 mm pitch) package with exposed thermal pad. Pin functions are fully defined in the MB9B110T Series datasheet (Document No. 002-04683 Rev.*C), including dedicated QPRC inputs (AIN/BIN/ZIN), LIN transceiver pins, and multiplexed peripheral I/O with port relocate capability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC / VSS | Power supply / Ground | Dual power domains: VCC supplies core/peripherals; VSS provides low-noise reference for analog blocks including ADC. |
| XTAL1 / XTAL2 | Main crystal oscillator input/output | Supports 4–48 MHz external crystal - primary clock source for PLL-based high-speed operation and USB timing. |
| OSC32K | 32.768 kHz sub-clock input | Drives Watch Counter and RTC functions; enables wake-up from Stop mode with ≤64 s interval resolution. |
| AINx / BINx / ZINx | Quadrature encoder inputs (x = 0–2) | Configurable edge-sensitive inputs per QPRC channel - directly interface incremental encoders for position/speed feedback in servo drives. |
| TXDn / RXDn | UART transmit/receive (n = 0–7) | Full-duplex double-buffered channels with hardware flow control (CTS/RTS on ch.4) - suitable for debug console and host communication. |
| SDA / SCL | I²C data/clock lines | Support Standard-mode (100 kbps) and Fast-mode (400 kbps) - connect to sensors, EEPROMs, and PMICs with minimal external components. |
Key Features
| Feature | Design Value |
|---|---|
| Hardware + Software Watchdog | Independent reset sources: hardware WD uses 100 kHz CR oscillator (active in Sleep/Timer modes); software WD runs on main clock - ensures fail-safe recovery under clock failure or firmware hang. |
| CRC Accelerator | Offloads CCITT CRC16 and IEEE-802.3 CRC32 computation - reduces CPU load by >90% during firmware update validation or communication frame integrity checks. |
| Port Relocate Function | Dynamic remapping of peripheral functions (e.g., UART, LIN, QPRC) to alternate GPIO pins - simplifies PCB layout and avoids signal congestion in dense 176-pin LQFP designs. |
| Low-Voltage Detection (LVD) | Two-stage monitoring: LVD1 triggers interrupt for graceful shutdown; LVD2 asserts reset below threshold - prevents erratic behavior during brown-out conditions. |
| Dual DMA Controller | 8-channel controller with independent bus - enables concurrent ADC-to-memory transfers, UART streaming, and timer-triggered memory moves without CPU intervention. |
Applications
| Industrial Motor Drive | Automotive Body Control Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MB9BF118SPMC-GE1 | Same FM3 platform, but with 2 MB Flash and identical peripherals - no change in pinout or clock architecture. | Required where firmware image size exceeds 1 MB (e.g., OTA update + dual-bank boot). | Select when future firmware growth or secure boot partitioning demands larger non-volatile storage. |
| STM32F303VCT6 | ARM Cortex-M4F core, 72 MHz max, 256 KB Flash, 48 KB SRAM; lacks QPRC and LIN 2.1 hardware support. | Suitable for cost-sensitive motor control without encoder feedback or automotive LIN compliance. | Choose only if application omits quadrature decoding and uses UART-based diagnostics instead of LIN. |
Compared with MB9BF116SPMC-GE1, the MB9BF118SPMC-GE1 offers scalable Flash without architectural trade-offs, while the STM32F303VCT6 sacrifices encoder interface and automotive protocol support for lower unit cost - making it viable only in non-LIN, non-encoder use cases.

FAQ
What is the maximum operating frequency and supported voltage range?
The MB9BF116SPMC-GE1 operates at up to 144 MHz using the main PLL clock sourced from a 4–48 MHz external crystal. Its supply voltage range is 2.7 V to 5.5 V, allowing direct compatibility with both 3.3 V and 5 V system rails. The internal voltage regulator maintains stable core operation across this range, and all I/O pins are 5 V tolerant where specified in the pin assignment table.
Does this MCU support hardware-based LIN 2.1 communication?
Yes, the MB9BF116SPMC-GE1 includes dedicated LIN hardware modules supporting full LIN 2.1 protocol compliance, including automatic break field generation (13–16 bit), delimiter control (1–4 bit), and error detection for parity, framing, and overrun. It operates in both master and slave modes without CPU overhead, and multiple LIN channels can be configured via the multi-function serial interface.
How many independent ADC channels and what conversion speed does it offer?
The device integrates three independent 12-bit successive approximation ADC units supporting up to 32 total input channels. Each unit achieves a minimum conversion time of 1.0 μs at 5 V supply, with built-in FIFO buffers (16-step for scan mode, 4-step for priority mode) and programmable priority levels for time-critical analog measurements.
What debug and trace capabilities are built in?
The MB9BF116SPMC-GE1 features Serial Wire JTAG Debug Port (SWJ-DP) and Embedded Trace Macrocell (ETM) support. It enables real-time instruction tracing, breakpoint setting, and memory inspection via standard ARM-compliant tools. The on-chip 16 KB trace buffer works with the Flash Accelerator to capture execution flow without external probes - essential for validating motor control timing and interrupt latency.
