Infineon Technologies CY9BF564LPMC-G-JNE2

Overview

CY9BF564LPMC-G-JNE2 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M4F microcontroller with FPU, 512 KB Flash, 64 KB SRAM, USB 2.0 Full-Speed device/host, single CAN 2.0B interface, and 15-channel 12-bit ADC. It operates up to 160 MHz and supports motor control via dedicated timers, PWM, and QPRC-used in industrial servo drives and embedded motion controllers.

For engineers reviewing the CY9BF564LPMC-G-JNE2 datasheet, CY9BF564LPMC-G-JNE2 pinout, CY9BF564LPMC-G-JNE2 application, or CY9BF564LPMC-G-JNE2 equivalent, key selection criteria include real-time motor control capability, dual USB mode support, integrated CRC accelerator, low-power deep-standby modes with RTC retention, and 5 V-tolerant GPIOs for industrial I/O interfacing.

Technical Context

This MCU implements a tightly coupled Arm Cortex-M4F core with Memory Protection Unit (MPU), NVIC supporting 128 peripheral interrupts, and SysTick timer for RTOS scheduling. Its dual Flash architecture includes MainFlash (512 KB) with accelerator and WorkFlash (32 KB) with configurable wait states up to 160 MHz operation.

The peripheral set integrates high-resolution timing (6.25 ns minimum resolution), hardware-accelerated CCITT CRC16/IEEE CRC32, DSTC with 128-channel descriptor-based DMA, and mixed-signal resources including two 12-bit DACs, quadrature encoder interface (QPRC), and dual watchdogs (hardware + software).

FAQ

What is the maximum operating frequency and how is it achieved?

The CY9BF564LPMC-G-JNE2 achieves up to 160 MHz via its main PLL clock sourced from an external 4–48 MHz crystal. The Flash Accelerator system enables zero-wait-state execution up to 72 MHz and maintains effective performance beyond that through prefetch and trace buffer optimization. Internal CR oscillators provide fallback clock sources during PLL lock loss.

Does this MCU support USB host functionality with external peripherals?

Yes-it integrates a full-featured USB 2.0 Full/Low-Speed host controller supporting bulk, interrupt, and isochronous transfers. It automatically detects device connect/disconnect events, handles IN/OUT token handshaking, and supports up to 256-byte packet lengths. External PHY is required, and USBVCC must be supplied at 3.0–3.6 V.

How does the QPRC interface support motor position feedback?

The Quadrature Position/Revolution Counter (QPRC) accepts AIN/BIN/ZIN signals with configurable edge detection, providing 16-bit position and revolution counters plus two 16-bit compare registers. It directly interfaces with standard incremental encoders and supports up/down counting, enabling precise rotor position tracking without CPU intervention.

What low-power modes retain RTC functionality while minimizing current draw?

Deep Standby RTC mode retains calendar, alarm, and 32-byte backup registers while powering only the RTC subsystem and 32.768 kHz oscillator from VBAT. Typical current consumption is <1.5 μA. This mode supports wake-up via RTC alarm or external interrupt, making it ideal for battery-backed timekeeping in energy meters and remote sensors.
