Product details
Overview
CY9BF564LQN-G-AVE2 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M4F microcontroller with FPU, operating up to 160 MHz, 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 real-time embedded systems.
For engineers reviewing the CY9BF564LQN-G-AVE2 datasheet, CY9BF564LQN-G-AVE2 pinout, CY9BF564LQN-G-AVE2 application, or CY9BF564LQN-G-AVE2 equivalent, key selection criteria include dual Flash architecture with security protection, 8-channel DMA + 128-channel DSTC for off-CPU data movement, 2-stage LVD reset/interrupt, RTC with leap-year support, and QPRC for encoder-based position sensing.
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 dual Flash memory system enables secure code execution (MainFlash) and firmware update storage (WorkFlash), each with independent wait-state control and shared code protection.
The peripheral set is optimized for deterministic real-time control: CAN interface supports 1 Mbps with 32 message buffers; multi-function serial interfaces (up to 6 channels) support UART, CSIO, LIN 2.1, and I²C (including Fast-mode Plus at 1 Mbps on ch.3/4); and motor control timers provide PWM, dead-time insertion, A/D trigger synchronization, and DTIF emergency stop interrupt.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Arm Cortex-M4F microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32H743VI | Higher clock (480 MHz), dual-core (Cortex-M7/M4), larger Flash (2 MB), no integrated CAN FD | Targets high-end HMI and AI-edge inference; lacks QPRC and LIN 2.1 native support | Choose when >160 MHz performance, large code footprint, or dual-core RTOS partitioning is required |
| RA6M5GFP | Same 200 MHz Cortex-M33 core, 1 MB Flash, 384 KB SRAM, CAN FD, but no USB host or DSTC | Focused on secure industrial connectivity; lacks motor-specific peripherals (DTIF, QPRC, PPG timers) | Prefer when TrustZone security, CAN FD, or long-term Renesas ecosystem support outweighs motor control feature set |
Compared with STM32H743VI and RA6M5GFP, CY9BF564LQN-G-AVE2 delivers superior integration for cost-sensitive motor control and body electronics-offering QPRC, LIN 2.1, DTIF, and descriptor-based DSTC without requiring external glue logic or software overhead.

FAQ
What is the maximum operating frequency and does it require external clock conditioning?
The CY9BF564LQN-G-AVE2 operates up to 160 MHz using its internal Main PLL, which accepts 4–48 MHz external crystal input (XTAL/XTALIN). No external clock conditioning circuitry is needed-the PLL includes built-in jitter suppression and dynamic frequency scaling support across all low-power modes.
How is code protection implemented across the dual Flash banks?
Code protection uses independent lock bits per Flash bank: MainFlash supports read-out protection (ROP) and write protection (WP) zones; WorkFlash shares ROP/WP settings but allows separate erase/write control. Both banks enforce protection during debug access and boot sequence verification, preventing unauthorized firmware extraction or overwrite.
Does the USB interface support both device and host roles simultaneously?
No-USB operates in exclusive device or host mode, selected at runtime via the USBPHYCTL register. The hardware supports full-speed (12 Mbps) in either role, with automatic device attach/detach detection in host mode and endpoint double-buffering in device mode, but not concurrent dual-role operation.
What peripheral resources are available for implementing a LIN 2.1 master node?
The MCU provides one dedicated LIN channel (CSIO or UART mode) with hardware LIN break field generation (13–16 bit length), break delimiter control (1–4 bit), automatic checksum calculation, and slave response timeout detection-fully compliant with LIN 2.1 specification without software bit-banging or external transceivers beyond standard LIN PHY.
