Product details
Overview
CY9AF315NAPMC-G-MNE2 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller with 512 KB on-chip Flash, 32 KB SRAM (split into two 16 KB banks), USB 2.0 Full-Speed device/host interface, and integrated motor control peripherals including QPRC, multi-function timers, and 12-bit ADCs. It operates up to 40 MHz and supports LIN 2.1, I²C, UART, CSIO, and external bus interface - deployed in industrial motor drives and embedded control systems.
For engineers reviewing the CY9AF315NAPMC-G-MNE2 datasheet, CY9AF315NAPMC-G-MNE2 pinout, CY9AF315NAPMC-G-MNE2 application, or CY9AF315NAPMC-G-MNE2 equivalent, key selection criteria include USB dual-role capability, 16-channel 12-bit ADC with FIFO, quadrature encoder support, 8-channel DMA, and 5V-tolerant GPIOs in the 100-pin LQFP package.
Technical Context
The CY9AF315NAPMC-G-MNE2 implements an Arm Cortex-M3 r2p1 core with NVIC supporting 48 peripheral interrupts and 16 priority levels, plus a 24-bit SysTick timer for RTOS scheduling. Its memory subsystem features zero-wait-state Flash execution and dual-bus-connected SRAM banks enabling concurrent CPU and DMA access.
Peripheral integration includes a dedicated USB PLL, dual-mode USB controller (device/host), eight-channel multi-function serial interface configurable per channel as UART/CSIO/LIN/I²C, and hardware-accelerated CCITT CRC16 and IEEE-802.3 CRC32 for data integrity verification in communication and storage paths.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit Arm Cortex-M3 microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F103VET6 | 72 MHz Cortex-M3, 512 KB Flash, 64 KB SRAM, no USB host, no QPRC, no external bus interface | Limited to USB device-only and simpler motor control; lacks hardware encoder counter and external memory expansion | Select when higher CPU clock and larger SRAM are needed but USB host and QPRC are unnecessary |
| RA4M1 (R7FA4M1AB3CFP) | 48 MHz Cortex-M4F, 256 KB Flash, 32 KB SRAM, USB device only, no external bus, no QPRC | Targets low-power HMI and sensor fusion; lacks motor-specific peripherals and memory expansion capability | Select for FPU-enabled signal processing where motor encoder counting and external memory are not required |
Compared with STM32F103VET6 and RA4M1, the CY9AF315NAPMC-G-MNE2 uniquely combines USB dual-role operation, hardware QPRC, and external bus interface - making it optimal for industrial motion controllers requiring both real-time encoder feedback and firmware extensibility via external Flash.

FAQ
What is the maximum operating frequency and supported voltage range?
The CY9AF315NAPMC-G-MNE2 operates at up to 40 MHz with a core supply voltage (VCC) range of 2.7 V to 5.5 V. USB I/O requires a separate 3.0–3.6 V supply (USBVCC) when the USB interface is active; otherwise, USBVCC may be tied to VCC within the full 2.7–5.5 V range for GPIO use.
Does this MCU support hardware-based motor control features like dead-time insertion?
Yes. The CY9AF315NAPMC-G-MNE2 includes dedicated motor control timers with configurable dead-time insertion, DTIF (motor emergency stop) interrupt generation, and hardware-synchronized A/D activation - all implemented in peripheral logic without CPU intervention.
Is the USB interface capable of both device and host functionality?
Yes. The integrated USB 2.0 Full-Speed controller supports dual-role operation: device mode (up to 6 endpoints, including double-buffered EP1 with 256-byte capacity) and host mode (supporting full/low-speed devices, automatic connect/disconnect detection, and 256-byte packet length).
How many ADC channels and what resolution does the on-chip converter provide?
The MCU integrates three 12-bit successive-approximation ADC units supporting up to 16 total input channels. Conversion time is 1.0 μs at 5 V, with hardware FIFO (16-step for scan mode, 4-step for priority mode) and programmable priority levels for time-critical sampling sequences.
