Product details
Overview
CY9AF314NAPMC-GNE2 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 8-channel Base Timers, dual QPRC units, and A/D converters. It operates at up to 40 MHz, supports 2.7–5.5 V supply, and targets embedded motor control and industrial automation systems requiring real-time I/O, LIN/UART/I²C/CSIO serial interfaces, and deterministic interrupt handling.
For engineers reviewing the CY9AF314NAPMC-GNE2 datasheet, CY9AF314NAPMC-GNE2 pinout, CY9AF314NAPMC-GNE2 application, or CY9AF314NAPMC-GNE2 equivalent, key selection criteria include its dual-bank SRAM architecture for concurrent code/data access, hardware LIN 2.1 support with configurable break field timing, USB host/device dual-mode operation with built-in PLL, and 8-channel DMA with independent bus arbitration-critical for high-throughput sensor and actuator data handling in motion control designs.
Technical Context
The CY9AF314NAPMC-GNE2 implements an Arm Cortex-M3 r2p1 core with NVIC supporting 48 peripheral interrupts and 16 priority levels, enabling precise real-time task scheduling in motor drive firmware. Its memory subsystem includes separate I-code and D-code buses for SRAM0 (16 KB), allowing simultaneous instruction fetch and data access without contention.
Peripheral integration centers on deterministic timing: Base Timers support 16-/32-bit PWM, PPG, and PWC modes; Multi-function Timers provide input capture, A/D activation compare, and waveform generation; and QPRC units deliver quadrature decoding with 16-bit position/revolution counters and dual compare registers-essential for closed-loop servo positioning.

FAQ
What is the maximum operating frequency and supported voltage range for CY9AF314NAPMC-GNE2?
The CY9AF314NAPMC-GNE2 operates at up to 40 MHz with a core supply voltage (VCC) range of 2.7 V to 5.5 V. Its USB I/O domain (USBVCC) requires 3.0 V to 3.6 V when USB functionality is active, or 2.7 V to 5.5 V when used as general-purpose I/O. These ranges are validated per Infineon's DC Characteristics table (Section 12.3.2) and support wide-input industrial power supplies without external regulation.
Does CY9AF314NAPMC-GNE2 support hardware debug interfaces, and which ones are implemented?
Yes, it supports Serial Wire JTAG Debug Port (SWJ-DP) for full boundary-scan and real-time debugging. The device does not include Embedded Trace Macrocell (ETM); only SWJ-DP is implemented per the datasheet revision *F (page 5). This enables standard ARM CoreSight debugging via J-Link or ST-Link v2-compatible probes without requiring additional trace pins or bandwidth.
How many A/D converter channels and what resolution does CY9AF314NAPMC-GNE2 provide?
The device integrates two 12-bit successive approximation A/D converters, supporting up to 16 input channels total. Each converter achieves 1.0 μs conversion time at 5 V supply, with FIFO-based scanning and priority-level conversion modes. This matches the specification in Section 1.3.7 of the datasheet (Document Number 002-04674 Rev. *F) and enables simultaneous sampling of motor phase currents and bus voltage.
Is external bus interface supported on CY9AF314NAPMC-GNE2, and what memory types can it connect to?
No, the CY9AF314NAPMC-GNE2 does not support the External Bus Interface. Per the datasheet footnote on page 2, this feature is explicitly excluded from the CY9AF314LA series (which includes CY9AF314NAPMC-GNE2). The device relies solely on on-chip Flash (512 KB) and SRAM (32 KB) for program and data storage, eliminating external memory complexity and PCB footprint.
