Product details
Overview
CY9AF311LAPMC1-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, QPRC, and multi-function timers. It operates up to 40 MHz, supports LIN 2.1, I²C, UART, CSIO, and runs on 2.7–5.5 V supply.
For engineers reviewing the CY9AF311LAPMC1-GNE2 datasheet, CY9AF311LAPMC1-GNE2 pinout, CY9AF311LAPMC1-GNE2 application, or CY9AF311LAPMC1-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 flow control exclusion in UART ch.4, and 100-pin LQFP package with 83 GPIOs.
Technical Context
The CY9AF311LAPMC1-GNE2 implements an Arm Cortex-M3 r2p1 core with NVIC supporting 48 peripheral interrupts and 16 priority levels, plus 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.
Peripherals include 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 dedicated motor control 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.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M3 r2p1, 40 MHz max operation - enables deterministic real-time control with Thumb-2 instruction set and low-latency interrupt handling. |
| Flash Memory | 512 KB, 0 wait-state read - supports fast code execution without cache, suitable for firmware with tight timing constraints. |
| SRAM | 32 KB total (SRAM0: 16 KB on I/D bus; SRAM1: 16 KB on system bus) - allows parallel instruction fetch and data access, critical for high-throughput DMA transfers. |
| USB Interface | Full-Speed device/host with 6 endpoints (EP0–EP5), double-buffered EP1 (256 B), EP0/2–5 (64 B) - enables embedded host capability for USB peripherals and device-mode connectivity to PCs. |
| A/D Converter | 12-bit SAR, 2 units, 1.0 μs conversion @ 5 V, FIFO + priority scanning - supports simultaneous sampling of multiple analog signals with configurable sequencing for motor current/voltage sensing. |
| Timers | 8-channel Base Timer (PWM/PPG/reload/PWC), 2-unit QPRC (16-bit position/revolution counters), 2-unit Multi-function Timer (input capture, output compare, waveform gen) - provides complete motor control signal generation and feedback processing in one chip. |
| Power Supply | VCC: 2.7–5.5 V; USBVCC: 3.0–3.6 V (USB I/O) or 2.7–5.5 V (GPIO) - enables single-supply designs with flexible voltage domain partitioning for mixed-signal operation. |
Pinout & Package
Package: 100-pin LQFP (14 mm × 14 mm, 0.5 mm pitch), RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC / VSS | Power / Ground | Dual power domains: VCC powers core/peripherals; separate USBVCC pin required for USB I/O compliance at 3.0–3.6 V. |
| XTAL / EXTAL | Main Clock Input | 4–48 MHz crystal or external clock input - primary timing source for CPU, PLL, and USB clock generation via internal multiplier. |
| OSC32K / OSC32KIN | Sub-Clock Input | 32.768 kHz crystal connection - enables low-power wake-up timer and RTC functionality during SLEEP/TIMER modes. |
| USB_DP / USB_DM | USB Differential Pair | Full-Speed USB 2.0 physical layer interface - requires 27 Ω series resistors and proper PCB routing for EMI control and signal integrity. |
| PA0–PA15, PB0–PB15, etc. | General-Purpose I/O | 83 total GPIOs with port relocate function - allows flexible peripheral mapping (e.g., UART on any supported pin group) and 5V-tolerant I/O on select variants (not applicable to CY9AF311LA). |
Key Features
| Feature | Design Value |
|---|---|
| Motor Control Timer Set | 8-channel Base Timer + 2-unit QPRC + 2-unit Multi-function Timer - enables closed-loop PMSM/BLDC control with encoder feedback, PWM generation, and emergency stop (DTIF) without external logic. |
| Dual-Mode USB Controller | Integrated device/host PHY and protocol stack support - eliminates need for external USB transceivers or bridge ICs in applications requiring both host (e.g., USB flash drive reader) and device (e.g., firmware update) roles. |
| Flexible Serial Interface | 8-channel multi-function serial interface (UART/CSIO/LIN/I²C per channel) - reduces pin count and PCB complexity by reusing same hardware blocks across communication protocols. |
| Low-Power Management | SLEEP/TIMER/STOP modes with sub-clock wake-up, LVD1/LVD2 monitoring, and hardware watchdog clocked by 100 kHz CR oscillator - ensures reliable operation during brown-out and battery-backed scenarios. |
| CRC Accelerator | Hardware CCITT CRC16 and IEEE-802.3 CRC32 calculation - offloads integrity checking from CPU during firmware OTA updates or CAN/LIN message validation, reducing latency and CPU load. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F303VCT6 | ARM Cortex-M4F core, 72 MHz, 256 KB Flash, 48 KB SRAM, no USB host, integrated op-amps/comparators | Better analog signal conditioning; lacks USB host and QPRC - unsuitable for encoder-based motor control requiring dual-role USB | Select when analog front-end integration outweighs USB host and motor timer requirements. |
| RA4M1 (R7FA4M1AB3CFM) | ARM Cortex-M4, 48 MHz, 256 KB Flash, 32 KB SRAM, USB device only, no QPRC, 12-bit ADC with 16-channel scan | Stronger security (Trusted Secure IP), lower power in STOP mode, but missing QPRC and USB host - limits use in bidirectional USB peripheral hubs | Prefer for secure, low-power IoT edge nodes where USB host and encoder counting are not required. |
Compared with STM32F303VCT6 and RA4M1, CY9AF311LAPMC1-GNE2 uniquely combines USB device/host duality, QPRC for precise position tracking, and motor-optimized timers in a single 100-pin LQFP package - making it optimal for cost-sensitive industrial motion control where dual-role USB connectivity and encoder feedback are mandatory.

FAQ
Does CY9AF311LAPMC1-GNE2 support external bus interface?
No. While the CY9A310A Series datasheet describes external bus interface capability, the CY9AF311LA variant explicitly excludes this feature per Section 1.1 "Product Lineup" and footnote on Page 3. This part supports only on-chip memory and peripheral interfacing via standard buses like UART, I²C, and USB.
What is the maximum ADC sampling rate achievable with priority conversion mode?
With priority conversion enabled across two 12-bit ADC units, the CY9AF311LAPMC1-GNE2 achieves up to 1 MSps aggregate sampling rate - derived from 1.0 μs per conversion at 5 V supply, supporting interleaved or sequential priority-triggered acquisitions for motor phase current monitoring.
Is hardware flow control supported on all UART channels?
No. Hardware flow control (CTS/RTS) is supported only on UART channel 4, and documentation confirms that CY9AF311LA does not support this feature - meaning all UART channels operate without automatic RTS/CTS handshake, requiring software-based flow control or external logic if needed.
How many USB endpoints are available in device mode, and what are their buffer sizes?
In USB device mode, CY9AF311LAPMC1-GNE2 supports six endpoints: Endpoint 0 (control, 64 B), Endpoints 1–5 (configurable transfer types). Endpoint 1 has a 256-byte double buffer; Endpoints 0 and 2–5 each have 64-byte double buffers - enabling concurrent bulk/interrupt transfers with minimal CPU intervention.
