Product details
Overview
CY9AF314LAPMC1-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 serial interfaces supporting UART, CSIO, LIN 2.1, and I²C. It operates at up to 40 MHz and targets embedded motor control and industrial automation systems.
For engineers reviewing the CY9AF314LAPMC1-GNE2 datasheet, CY9AF314LAPMC1-GNE2 pinout, CY9AF314LAPMC1-GNE2 application, or CY9AF314LAPMC1-GNE2 equivalent, key selection criteria include its dual-bank SRAM architecture, USB host/device capability with built-in PLL, LIN 2.1 support with configurable break field length, 12-bit ADC conversion time of 1.0 μs at 5 V, and 100-pin LQFP package with 83 GPIOs including port relocation.
Technical Context
The CY9AF314LAPMC1-GNE2 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 integration. Its memory subsystem features zero-wait-state Flash execution and dual-bus-connected SRAM banks-SRAM0 on I-code/D-code buses and SRAM1 on the system bus-enabling concurrent CPU and DMA access.
Peripherals include a full-featured USB controller with six endpoints (Endpoint 1: 256-byte double buffer; Endpoints 0,2–5: 64-byte double buffers), eight-channel DMA with burst/block/demand transfer modes, and dedicated motor control blocks: quadrature position/revolution counters (QPRC), multi-function timers with A/D activation compare and DTIF emergency stop, and base timers configurable as PWM, PPG, reload, or PWC units.

FAQ
What is the maximum operating frequency and voltage range for CY9AF314LAPMC1-GNE2?
The CY9AF314LAPMC1-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, but defaults to the VCC range when used solely for GPIO. These specifications are validated per Infineon's DC Characteristics table in Rev. *F datasheet.
Does CY9AF314LAPMC1-GNE2 support hardware flow control on UART channels?
No, CY9AF314LAPMC1-GNE2 does not support hardware flow control (CTS/RTS) on any UART channel. The datasheet explicitly states this limitation for CY9AF311LA, F312LA, and F314LA variants. UART channels rely on software-controlled flow or FIFO-based buffering instead.
Is external bus interface supported on this part?
No, the CY9AF314LAPMC1-GNE2 does not support the External Bus Interface. Infineon's datasheet confirms this feature is excluded from CY9AF311LA, F312LA, and F314LA variants. All memory expansion must be handled via SPI, USB, or external serial flash interfaced through CSIO or UART.
What debug interfaces are available on CY9AF314LAPMC1-GNE2?
The CY9AF314LAPMC1-GNE2 supports Serial Wire JTAG Debug Port (SWJ-DP) only. It does not include Embedded Trace Macrocell (ETM) support, as confirmed in the "Debug" section of the datasheet for CY9AF314LA variants. SWJ-DP enables full breakpoint, watchpoint, and memory inspection capabilities via standard Arm debug tools.
