Product details
Overview
CY9AF311KPMC1-G-JNE2 from Infineon Technologies (formerly Cypress) is a 32-bit ARM® Cortex®-M3 microcontroller optimized for motor control and embedded real-time applications. It operates at up to 40 MHz, integrates 128 KB MainFlash + 32 KB WorkFlash, 16 KB SRAM (8 KB × 2 banks), USB 2.0 Full-Speed device/host interface, and dual 12-bit ADCs with 1.0 µs conversion time. Used in industrial motor drives requiring precise timing, analog sensing, and LIN/UART communication.
For engineers reviewing the CY9AF311KPMC1-G-JNE2 datasheet, CY9AF311KPMC1-G-JNE2 pinout, CY9AF311KPMC1-G-JNE2 application, or CY9AF311KPMC1-G-JNE2 equivalent, key selection criteria include USB host/device dual-mode support, QPRC encoder interface, 8-channel base timer with PWM/PPG modes, RTC with leap-year handling, and dual watchdog timers with independent clock domains.
Technical Context
The CY9AF311KPMC1-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 integration. Its memory subsystem features two independent Flash banks (MainFlash and WorkFlash) with zero-wait-state operation and shared code protection, and dual-bank SRAM (SRAM0 on I/D-code bus, SRAM1 on system bus) enabling concurrent CPU/DMA access.
Peripheral architecture includes a multi-function serial interface supporting UART, CSIO, LIN 2.1, and I²C across four channels - with ch.0/ch.1 featuring 16×9-bit FIFOs - plus a dedicated USB PHY with built-in PLL, 8-channel DMA controller with 32-bit addressing, and motor-focused peripherals: QPRC with AIN/BIN/ZIN edge-configurable inputs, dual 12-bit SAR ADCs with scan/priority modes and FIFO buffering, and base timers supporting 16-/32-bit PWM, PPG, reload, and PWC modes.

FAQ
What power supply configurations does CY9AF311KPMC1-G-JNE2 support?
The device operates from a single 2.7 V to 5.5 V VCC supply for core and I/O. When USB is active, USBVCC0 requires 3.0–3.6 V; otherwise, it accepts 2.7–5.5 V for GPIO use. The low-voltage detector provides two-stage monitoring (LVD1 for interrupt, LVD2 for reset) with user-configurable thresholds.
Does CY9AF311KPMC1-G-JNE2 support debug via SWD or JTAG?
Yes - it features a Serial Wire JTAG Debug Port (SWJ-DP) compliant with ARM CoreSight standards. Debug access is supported via SWD (2-pin) or JTAG (5-pin) interfaces, enabling full breakpoint, register, and memory inspection during development and field diagnostics.
How is the USB clock generated without an external crystal?
The MCU integrates a main PLL that accepts the 4–48 MHz main clock (from external crystal or internal CR oscillator) and multiplies it to generate the precise 48 MHz USB clock. This eliminates the need for a separate 48 MHz crystal or oscillator, reducing BOM cost and board space.
Can the WorkFlash be used for EEPROM emulation?
Yes - WorkFlash (32 KB) is designed for frequent rewrites and shares security features with MainFlash. Its zero-wait-state operation and dedicated erase/write control registers enable robust EEPROM emulation for parameter storage, calibration data, or event logs with wear-leveling managed in firmware.
