Overview
CY9AF311MAPMC-GNE2 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller with 512 KB on-chip Flash, 32 KB SRAM (16 KB SRAM0 + 16 KB SRAM1), USB 2.0 Full-Speed device/host interface, and integrated motor control peripherals including 8-channel Base Timers, QPRC, and multi-function serial interfaces (UART/CSIO/LIN/I²C). It operates at up to 40 MHz and targets embedded motor control and industrial automation systems.
For engineers reviewing the CY9AF311MAPMC-GNE2 datasheet, CY9AF311MAPMC-GNE2 pinout, CY9AF311MAPMC-GNE2 application, or CY9AF311MAPMC-GNE2 equivalent, key selection criteria include USB dual-role capability, 12-bit ADC with FIFO and priority scanning, hardware flow control on UART ch.4, external bus interface support, and SWJ-DP debug port compatibility.
Technical Context
The CY9AF311MAPMC-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 enabling concurrent CPU and DMA access.
Peripheral architecture includes a dedicated USB PLL, eight-channel DMA controller with burst/block/demand transfer modes, three 12-bit ADC units (1.0 µs conversion @5 V), and motor-specific blocks: QPRC for encoder position tracking, multi-function timers with dead-time insertion and DTIF interrupt, and base timers configurable as PWM/PPG/reload/PWC.

FAQ
What is the maximum operating frequency of the CY9AF311MAPMC-GNE2?
The CY9AF311MAPMC-GNE2 operates at up to 40 MHz using its Arm Cortex-M3 core. This frequency is achieved with the main clock sourced from an external 4–48 MHz crystal or oscillator, or via the internal high-speed CR oscillator (4 MHz) multiplied by the main PLL. The 40 MHz limit ensures stable timing margins for all on-chip peripherals including USB, ADC, and timers.
Does this MCU support USB host functionality?
Yes, the CY9AF311MAPMC-GNE2 integrates a full-featured USB 2.0 host controller supporting Low-Speed and Full-Speed devices, bulk/interrupt/isochronous transfers, automatic device connect/disconnect detection, and up to 256-byte packet length. It requires only external USB connectors and ESD protection-no external PHY or hub IC is needed.
How many ADC channels does it have, and what is their resolution and speed?
The CY9AF311MAPMC-GNE2 includes three independent 12-bit successive approximation ADC units, supporting up to 16 total analog input channels. Each unit achieves 1.0 µs conversion time at 5 V supply, with configurable FIFO depth (16 steps for scan mode, 4 steps for priority mode) and two-level priority arbitration for time-critical sampling.
Is external memory interface supported, and what types can it connect to?
Yes, the CY9AF311MAPMC-GNE2 features an External Bus Interface supporting SRAM and NOR Flash devices. It provides up to 8 chip selects, 8-/16-bit data width, up to 25-bit addressing (256 MB address space), address/data multiplexing, and external RDY signal support for timing flexibility with slower memories.
