It is fast enough to run a field-oriented control loop for a BLDC motor at 10 kHz PWM update or handle a Modbus RTU stack with a 1 ms tick, but it does not carry the power and layout cost of a 120 MHz+ part. The Cortex-M3 core includes a hardware single-cycle multiply and a 12-cycle divide, so the 40 MHz clock still gives you about 0.8 DMIPS/MHz — roughly 32 DMIPS total. That is enough for most real-time control tasks without needing a cache or a prefetch buffer. The Flash wait state is 0 at 40 MHz, so there is no pipeline stall penalty on tight loops. 512 KB of Flash is generous for a mid-range MCU. It holds a full FreeRTOS or ThreadX kernel plus a TCP/IP stack, a CANopen or Modbus application layer, and still leaves room for a bootloader with OTA staging. The 32 KB SRAM is the tighter resource — enough for a few 1 KB communication buffers and a modest heap, but you will need to watch dynamic allocation if you are running a GUI or a large data logger. The RAM is organised as 32K x 8, so it maps cleanly to byte-addressable variables and stack. ## 100-LQFP package — footprint and thermal notes The 100-LQFP (14x14 mm) with 0.5 mm pitch is a standard, board-friendly package. The 83 I/O lines fan out to the perimeter, so a two-layer PCB can route most signals if the layout is planned. The exposed thermal pad on the bottom (the 14x14 mm die-attach paddle) is the primary heat path — above 85°C ambient with all I/O switching, a via stitch under the pad to the ground plane keeps the junction temperature inside the 105°C limit. The package is MSL 3, so a bake before reflow is needed if the moisture-barrier bag has been open longer than the floor-life window. ## Connectivity and peripherals for industrial control The 16-channel 12-bit ADC samples at a rate typical for the class — enough for current sensing on a three-phase motor (three shunt resistors, three phase voltages) with channels left over for thermistors and a potentiometer. ## Active lifecycle — no redesign pressure For a production BOM line, this removes the urgency to qualify a drop-in replacement or stockpile for an LTB.","metaTitle":"Infineon CY9AF116NAPMC-G-MNE2 ARM Cortex-M3 MCU, 40 MHz","metaDescription":"Infineon CY9AF116NAPMC-G-MNE2 FM3 MB9A110A 32-bit ARM Cortex-M3 MCU. 40 MHz core, 512 KB Flash, 32 KB RAM, 83 I/O, -40 to 105°C.
