Product details
Overview
CY9BF564KQN-G-AVE2 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M4F microcontroller with FPU, 160 MHz max CPU frequency, 512 KB MainFlash + 32 KB WorkFlash, 64 KB SRAM (32+16+16), and integrated CAN 2.0B, USB 2.0 Full-Speed device/host, and 15-channel 12-bit ADC. It targets motor control and industrial automation systems requiring real-time processing, deterministic timing, and mixed-signal integration.
For engineers reviewing the CY9BF564KQN-G-AVE2 datasheet, CY9BF564KQN-G-AVE2 pinout, CY9BF564KQN-G-AVE2 application, or CY9BF564KQN-G-AVE2 equivalent, key selection criteria include its dual Flash architecture with security protection, 8-channel DMA + 128-channel DSTC for off-CPU data movement, 6x multi-function serial interfaces (UART/CSIO/LIN/I²C), and support for deep-standby RTC with VBAT backup.
Technical Context
This MCU implements a tightly coupled Arm Cortex-M4F core with Memory Protection Unit (MPU), NVIC supporting 128 peripheral interrupts across 16 priority levels, and SysTick timer for RTOS scheduling. Its clock system integrates five sources-including 4–48 MHz main oscillator, 32.768 kHz sub-clock, and Main PLL-with Clock Supervisor (CSV) for external oscillator failure detection and Low-Voltage Detector (LVD) with two-stage reset/interrupt thresholds.
The peripheral subsystem includes a dedicated Motor Control Timer unit with dead-time insertion, DTIF emergency stop, and A/D activation compare; QPRC for encoder position tracking; and dual watchdogs (hardware-reset-capable CR-based and software-configurable). Power management supports six low-power modes, including Deep Standby RTC with optional RAM retention and VBAT-supplied calendar circuitry.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit Arm Cortex-M4F microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32H743VI | Higher performance (480 MHz), dual-core option, larger Flash (2 MB), no integrated CAN FD but supports classic CAN 2.0B - lacks VBAT-backed RTC and QPRC | Better suited for HMI + control co-processing; requires external encoder interface IC and separate RTC backup solution | Select when needing >200 DMIPS or dual-core isolation; avoid if encoder position tracking or battery-backed timekeeping is mandatory |
| RA6M5GFP | Same Cortex-M4F core (200 MHz), 1 MB Flash, 384 KB RAM, CAN FD support, no USB host - includes TrustZone but lacks DSTC and motor-specific timers | Stronger security focus for connected devices; limited motor control peripherals compared to FM4's QPRC and DTIF | Prefer for secure firmware updates and cloud-connected edge nodes; not optimal for cost-sensitive motor drive designs requiring integrated motion control blocks |
Compared with STM32H743VI and RA6M5GFP, CY9BF564KQN-G-AVE2 offers unique integration of QPRC, DTIF, VBAT-backed RTC, and dual Flash with security - making it more suitable for cost-constrained, safety-aware industrial motor control where peripheral consolidation reduces BOM and layout complexity.

FAQ
What is the maximum operating temperature range for CY9BF564KQN-G-AVE2?
The CY9BF564KQN-G-AVE2 is rated for industrial temperature range: –40 °C to +85 °C ambient. This is confirmed in Section 12.1 (Absolute Maximum Ratings) and Section 12.2 (Operating Ranges) of the official datasheet (002-04922 Rev. *C), with all electrical characteristics guaranteed across this range under specified VCC and loading conditions.
Does CY9BF564KQN-G-AVE2 support CAN FD?
No. The integrated CAN controller complies strictly with ISO 11898-1:2015 for CAN 2.0A/B only, with a maximum bit rate of 1 Mbps and 32 message buffers. It does not implement CAN FD features such as flexible data-rate, extended data length, or CRC-17/21. For CAN FD, designers must select alternate FM4 variants or external transceivers with protocol translation.
How is flash security implemented on this MCU?
Security is enforced via hardware-based code protection on both MainFlash and WorkFlash, including read-out prevention, write/erase lock bits per sector, and boot vector masking. The protection mechanism is described in Section 3.3 ("Security Functions") of the FM4 Peripheral Manual (002-04856), and cannot be bypassed without physical decapsulation or factory-level unlock sequences.
Can the USB interface operate in host mode without an external PHY?
Yes. The USB module includes a full-speed (12 Mbps) transceiver compliant with USB 2.0 specifications, eliminating the need for an external PHY. Host mode supports Low-Speed (1.5 Mbps) and Full-Speed devices, automatic connect/disconnect detection, and IN/OUT token handshake - all handled internally per Section 7.3.1 of the datasheet.
