Infineon Technologies CY9AF314LAPMC-GNE2

Overview

CY9AF314LAPMC-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 multi-function timers with dead-time insertion. It operates at up to 40 MHz, supports 2.7–5.5 V supply, and targets embedded motor control and industrial automation systems.

For engineers reviewing the CY9AF314LAPMC-GNE2 datasheet, CY9AF314LAPMC-GNE2 pinout, CY9AF314LAPMC-GNE2 application, or CY9AF314LAPMC-GNE2 equivalent, key selection criteria include USB dual-role capability, 16-bit A/D converter with FIFO and priority scanning, external bus interface support (disabled in this variant), hardware CRC acceleration for CCITT CRC16/IEEE-802.3 CRC32, and SWJ-DP debug interface without ETM.

Technical Context

The CY9AF314LAPMC-GNE2 implements an Arm Cortex-M3 r2p1 core with NVIC supporting 48 peripheral interrupts and 16 priority levels, plus a 24-bit SysTick timer. Its memory subsystem features zero-wait-state Flash execution and dual-bus-connected SRAM banks-SRAM0 on I-code/D-code buses, SRAM1 on system bus-enabling concurrent CPU and DMA access.

Peripheral integration includes a full-featured USB controller with built-in PLL, eight-channel DMA with burst/block/demand transfer modes, three 12-bit ADC units (2 active in this variant), and motor-focused timing resources: 8-channel base timers, 2-unit QPRC with 16-bit position/revolution counters, and multi-function timers supporting PWM, DC chopper, and A/D activation triggers.

FAQ

Does CY9AF314LAPMC-GNE2 support USB host mode with external device enumeration?

Yes. The device integrates a full USB 2.0 Full/Low-Speed host controller with automatic device connect/disconnect detection, IN/OUT token handshake, and support for up to 256-byte packets. It enumerates standard USB Class devices such as HID, CDC, and mass storage without requiring external PHY or hub logic.

What is the maximum operating frequency of the internal main PLL?

The main PLL supports output frequencies up to 80 MHz when driven by the 4–48 MHz main clock source. However, the Cortex-M3 core is rated for 40 MHz operation, and all peripherals-including USB PLL-are configured to operate within their specified timing limits at that frequency.

Is the External Bus Interface (EBI) functional in CY9AF314LAPMC-GNE2?

No. According to the CY9A310A Series datasheet (Rev. *F), the CY9AF314LA variant explicitly excludes External Bus Interface support. This omission reduces pin count and simplifies PCB layout for applications relying solely on on-chip Flash/SRAM and serial peripherals.

How many A/D converter units are implemented in this specific part?

This part implements two 12-bit successive-approximation A/D converters, each with independent trigger sources, FIFO buffers, and priority-level scanning. The third ADC unit present in higher variants (e.g., CY9AF315MA) is disabled in CY9AF314LAPMC-GNE2 per silicon configuration.
