Product details
Overview
CY9AF311KPMC-G-JNE2 from Infineon Technologies (formerly Cypress) is a 32-bit ARM® Cortex®-M3 microcontroller with 128 KB MainFlash, 32 KB WorkFlash, 16 KB SRAM (8 KB SRAM0 + 8 KB SRAM1), USB 2.0 Full-Speed device/host interface, and integrated motor control peripherals including 8-channel 12-bit ADC (1.0 μs conversion @5 V), QPRC, and multi-function timers. It operates at up to 40 MHz and supports industrial embedded motor control systems requiring real-time position sensing and LIN/UART/I²C/CSIO communication.
For engineers reviewing the CY9AF311KPMC-G-JNE2 datasheet, CY9AF311KPMC-G-JNE2 pinout, CY9AF311KPMC-G-JNE2 application, or CY9AF311KPMC-G-JNE2 equivalent, this page delivers verified technical context, package mapping, peripheral timing constraints, low-power mode behavior, and validated alternative MCUs for FM3-based motor control designs.
Technical Context
The CY9AF311KPMC-G-JNE2 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 scheduling. Its dual Flash architecture separates application code (MainFlash) from parameter storage (WorkFlash), both zero-wait-state and sharing security-based code protection.
Peripheral integration includes a dedicated USB PLL for clock generation from the main oscillator, dual-mode USB (Full-Speed device + Full/Low-Speed host), and a QPRC block with configurable AIN/BIN/ZIN edge detection, 16-bit position/revolution counters, and two 16-bit compare registers - enabling precise encoder-based motion control without CPU intervention.

FAQ
What is the maximum operating frequency and supported voltage range for CY9AF311KPMC-G-JNE2?
The CY9AF311KPMC-G-JNE2 operates at up to 40 MHz and supports a wide VCC supply range of 2.7 V to 5.5 V. Its USB I/O voltage (USBVCC0) is 3.0–3.6 V when USB is active, or 2.7–5.5 V when used as general-purpose I/O. This flexibility enables direct interfacing with both 3.3 V and 5 V systems without level shifters.
Does CY9AF311KPMC-G-JNE2 support USB host functionality, and what transfer types are available?
Yes, it supports USB 2.0 Full-Speed and Low-Speed host mode with Bulk, Interrupt, and Isochronous transfers. It automatically detects device connection/disconnection, handles IN/OUT token handshakes, supports up to 256-byte packet length, and includes wake-up capability - enabling plug-and-play peripheral attachment without external USB host controllers.
How does the QPRC block function, and which pins are dedicated to it?
The QPRC uses P20 (AIN), P21 (BIN), and P22 (ZIN) pins to monitor quadrature encoder signals. Each input supports configurable edge detection (rising/falling/both) and digital filtering. The block maintains independent 16-bit position and revolution counters plus two 16-bit compare registers - allowing hardware-triggered interrupts on position thresholds without CPU polling.
What low-power modes are available, and what is the lowest achievable current consumption?
Six low-power modes are supported: SLEEP, TIMER, RTC, STOP, Deep stand-by RTC, and Deep stand-by STOP. In Deep stand-by RTC mode, the device maintains RTC operation with typical current consumption below 1 μA (at 3.3 V, 25°C), powered solely by the 32.768 kHz sub-clock - ideal for battery-backed timekeeping in energy-constrained applications.
