It packs 83 general-purpose I/O lines and a full set of peripherals including DMA, LVD, POR, PWM, and WDT, plus connectivity options like CSIO, EBI/EMI, I²C, LINbus, SPI, and UART/USART. The onboard data converter is a 16-channel 12-bit SAR ADC. This part is built for industrial control, motor drives, and outdoor telecom gear where the -40°C to 105°C temperature range and 2.7 V to 5.5 V supply flexibility matter. ## Package and mounting At 40 MHz the ARM Cortex-M3 core delivers enough throughput for real-time control loops, sensor fusion, and communication protocol handling without breaking a sweat. The 512 KB Flash is large enough to hold a moderate application stack plus a bootloader, so you can skip external memory in many designs. The 32K x 8 SRAM gives you room for a couple of moderate buffers and a real-time OS heap. If you need more muscle, the Infineon XMC4500 series (Cortex-M4 at 120 MHz) is a step up in both speed and DSP capability, but it runs on a narrower supply range and tops out at 85°C or 125°C depending on the variant. ## Lifecycle and sourcing reality The CY9AF116NAPMC-GNE2 carries an Active lifecycle status and is RoHS3 compliant. ## Package and field-service notes The 100-LQFP package (14x14 mm body) is a standard fine-pitch QFP that can be hand-soldered with a fine-tip iron and some flux — no hot-air station required if you take your time. For field swaps, keep a few spares in your kit and you will be fine.","metaTitle":"CY9AF116NAPMC-GNE2 ARM Cortex-M3 MCU, 40 MHz, 512 KB Flash","metaDescription":"Infineon CY9AF116NAPMC-GNE2 32-bit ARM Cortex-M3 MCU, 40 MHz, 512 KB Flash, 32K x 8 RAM, 83 I/O, -40 to 105°C, 100-LQFP.
