Product details
Overview
MB9AF111NAPMC-G-JNE2 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller with 64 KB on-chip Flash, 16 KB SRAM, 40 MHz max CPU frequency, 12-bit ADC (9 channels), and integrated motor control peripherals including Base Timers (8 ch), QPRC (2 ch), and LIN/UART/I²C/CSIO serial interfaces. It targets cost-sensitive industrial motor control and embedded automation systems requiring real-time PWM, position sensing, and multi-protocol communication.
For engineers reviewing the MB9AF111NAPMC-G-JNE2 datasheet, MB9AF111NAPMC-G-JNE2 pinout, MB9AF111NAPMC-G-JNE2 application, or MB9AF111NAPMC-G-JNE2 equivalent, key selection criteria include its LQFP-100 package, 2.7–5.5 V supply range, dual watchdog (HW + SW), CRC accelerator for data integrity, and port relocation support for flexible peripheral pin assignment in space-constrained designs.
Technical Context
This MCU implements a deterministic real-time execution environment via the Arm Cortex-M3 r2p1 core with NVIC supporting 48 peripheral interrupts and 16 priority levels. Its memory subsystem includes separate I-code/D-code buses for SRAM0 (16 KB) and system bus-connected SRAM1 (16 KB), enabling concurrent instruction fetch and data access.
The peripheral architecture integrates dedicated hardware blocks for motor control: dual QPRC units for quadrature encoder position tracking, 8-channel Base Timers configurable as PWM/PPG/reload timers, and A/D activation compare logic synchronized to timer events - all operating independently of CPU cycles to minimize jitter in closed-loop timing-critical applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M3 r2p1, 40 MHz max - delivers deterministic interrupt latency and efficient Thumb-2 code density for compact firmware in resource-limited systems. |
| Flash Memory | 64 KB, 0-wait-state read - enables fast instruction execution without cache, reducing BOM cost and power vs. external memory solutions. |
| SRAM | 16 KB total (SRAM0 + SRAM1), split-bus architecture - allows simultaneous CPU instruction fetch and DMA data transfer without bus contention. |
| A/D Converter | 12-bit SAR, 9 channels, 1.0 μs conversion @ 5 V - supports high-resolution analog feedback sampling for motor current/voltage monitoring at ≥1 MSPS effective rate. |
| Serial Interfaces | 8-channel multi-function UART/CSIO/LIN/I²C - provides protocol flexibility for sensor fusion (I²C), diagnostics (LIN 2.1), and host communication (UART with hardware flow control on ch.4). |
| Timers | 8 Base Timers + 2 QPRC + Dual Timer + Watch Counter - enables precise PWM generation, encoder-based position tracking, and low-power wake-up scheduling in single-chip motor drives. |
| Power Supply | 2.7–5.5 V operation - accommodates wide-input industrial power rails and battery-backed operation without external regulators. |
Pinout & Package
MB9AF111NAPMC-G-JNE2 is housed in a 100-pin LQFP (LQI100) package with 0.65 mm pitch, exposing 83 general-purpose I/O pins (including 5V-tolerant options), dedicated debug pins (SWJ-DP), and peripheral function multiplexing via port relocation registers (EPFR). Pin assignment supports full peripheral functionality only when using the LQI100 package variant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P00/TRSTX/MCSX7_1 | JTAG Test Reset Input | Active-low asynchronous reset for boundary-scan testing; also serves as memory chip select 7 when relocated. |
| P0A/SIN4_0/INT00_2/FRCK1_0/MCSX1_1 | Serial Input / External Interrupt / Frame Clock | Primary UART receive pin; configurable as edge-triggered interrupt source or frame sync input for synchronous serial protocols. |
| P60/SIN5_0/TIOA2_2/INT15_1/MRDY_1 | Serial Input / Timer Output A / Ready Signal | Supports daisy-chained CSIO slave operation; MRDY output signals external memory readiness to coordinate burst transfers. |
| P0F/NMIX/CROUT_1 | Non-maskable Interrupt / Clock Output | Dedicated NMI input for critical fault handling; CROUT provides programmable clock output for external peripherals or test instrumentation. |
| VCC (pins 1, 97, 98) | Core & I/O Power Supply | Three independent VCC pins reduce IR drop and noise coupling; must be decoupled locally per datasheet layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Port Relocation Function | Permits dynamic assignment of peripheral functions (e.g., UART, timer outputs) to alternate GPIO pins via EPFR registers - simplifies PCB routing and avoids signal congestion in dense layouts. |
| Quadrature Position Counter (QPRC) | Two independent 16-bit counters with AIN/BIN/ZIN inputs and configurable edge detection - directly measures rotary encoder position and revolution count without CPU intervention. |
| CRC Accelerator | Hardware CCITT CRC16 and IEEE-802.3 CRC32 computation - offloads integrity checking from firmware, reducing CPU load during firmware updates or sensor data logging. |
| Dual Watchdog Architecture | Separate hardware (CR oscillator-clocked) and software watchdogs - ensures fail-safe reset even during deep sleep modes where main clock is stopped. |
| Low-Voltage Detection (LVD) | Two-stage monitoring (LVD1 interrupt, LVD2 reset) with user-configurable thresholds - prevents erratic operation during brown-out conditions in industrial power environments. |
Applications
| Industrial Motor Drive | Automated HVAC Control |
|---|---|
Use Scenario: Closed-loop speed/position control of BLDC motors in factory automation conveyors. IC Role / Device Role / Timing Role: Real-time PWM generation, quadrature encoder position capture via QPRC, and current-sense ADC sampling synchronized to timer events.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit motor control microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F303VCT6 | ARM Cortex-M4F core, 72 MHz, 256 KB Flash, 48 KB RAM, no QPRC, integrated op-amps/comparators | Better analog signal conditioning but lacks dedicated quadrature encoder counters; requires software-based position tracking | Select when analog front-end integration outweighs encoder processing efficiency |
| RA4M1 (R7FA4M1AB3CFM) | ARM Cortex-M4, 48 MHz, 256 KB Flash, 32 KB RAM, 12-bit ADC (24 ch), no external bus interface | Higher ADC channel count and faster core, but no external memory expansion capability for firmware-over-the-air storage | Select for sensor-rich applications needing large local data buffers without external NOR Flash |
Compared with STM32F303VCT6 and RA4M1, MB9AF111NAPMC-G-JNE2 offers superior deterministic motor control through hardware QPRC and Base Timer synchronization, lower BOM cost via integrated LIN/UART/CSIO, and external bus support for legacy industrial memory interfaces - making it optimal for cost-sensitive, encoder-driven motion control.

FAQ
What debug interface does MB9AF111NAPMC-G-JNE2 support?
MB9AF111NAPMC-G-JNE2 supports Serial Wire JTAG Debug Port (SWJ-DP) compliant with ARM CoreSight standards. It does not include Embedded Trace Macrocell (ETM); trace capabilities are limited to SWO (Single Wire Output) for printf-style debugging and event tracing. The TDI/TDO/TMS/TCK/TRSTX pins are dedicated to JTAG, while SWDIO/SWCLK provide Serial Wire Debug access.
Does MB9AF111NAPMC-G-JNE2 support hardware flow control on all UART channels?
No - hardware flow control (CTS/RTS) is supported only on UART channel 4, as confirmed in the CY9A110A datasheet Rev. *H, Section 4.3. Channels 0–3 lack RTS/CTS signal generation logic. This limitation applies specifically to the MB9AF111NAPMC-G-JNE2 variant, which maps to the CY9AF111LA/NA product line with 64 KB Flash and 100-pin LQFP packaging.
What is the maximum operating temperature range for this MCU?
MB9AF111NAPMC-G-JNE2 is rated for industrial temperature operation from −40 °C to +85 °C, as specified in the "Recommended Operating Conditions" section (12.2) of the CY9A110A datasheet Rev. *H. This range is validated across all electrical characteristics including Flash write/erase endurance, ADC accuracy, and clock stability under thermal stress.
Can the on-chip SRAM be used for stack and heap allocation simultaneously?
Yes - SRAM0 (16 KB) and SRAM1 (16 KB) are physically separate memory blocks with independent bus connections. SRAM0 is accessible via I-code and D-code buses for instruction and data, while SRAM1 connects to the system bus. Linker scripts can allocate stack to SRAM0 and heap to SRAM1 to prevent contention during high-interrupt-rate operation, as demonstrated in Infineon's FM3 reference designs.
