Infineon Technologies CY9BF565LPMC1-G-JNE2

Overview

CY9BF565LPMC1-G-JNE2 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M4F microcontroller with FPU, 512 KB MainFlash, 32 KB WorkFlash, 64 KB total SRAM (32+16+16), and integrated USB 2.0 Full-Speed device/host, CAN 2.0B, and six multi-function serial interfaces. It operates up to 160 MHz and targets motor control, industrial automation, and embedded connectivity applications.

For engineers reviewing the CY9BF565LPMC1-G-JNE2 datasheet, CY9BF565LPMC1-G-JNE2 pinout, CY9BF565LPMC1-G-JNE2 application, or CY9BF565LPMC1-G-JNE2 equivalent, key selection criteria include real-time peripheral integration (QPRC, dual timer, RTC), 12-bit ADC with 0.5 μs conversion, 12-bit DAC, and 48 GPIOs in 64-pin LQFP package with 5 V-tolerant I/O capability.

Technical Context

This MCU implements a tightly coupled Arm Cortex-M4F core (r0p1) with Memory Protection Unit (MPU), NVIC supporting 128 peripheral interrupts and 16 priority levels, and SysTick for OS task scheduling. Its dual Flash architecture separates code execution (MainFlash) from data logging or firmware updates (WorkFlash), each with independent security and wait-state management.

The peripheral subsystem integrates hardware-accelerated functions including DSTC (128-channel descriptor-based DMA), CRC accelerator (CCITT CRC16/IEEE CRC32), and dedicated motor control blocks: multi-function timers with dead-time insertion, A/D activation compare, and QPRC for encoder position tracking - all operating synchronously with the 160 MHz system clock.

Key Specifications

Pinout & Package

FAQ

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

The CY9BF565LPMC1-G-JNE2 achieves up to 160 MHz system clock via its internal Main PLL, which accepts 4–48 MHz input from external crystal or oscillator. The Flash Accelerator ensures zero-wait-state execution up to 72 MHz and maintains equivalent performance beyond that through prefetch and trace buffer optimization-enabling deterministic real-time response without software wait-state insertion.

Does this MCU support USB device and host simultaneously?

Yes-it integrates a dual-role USB 2.0 Full-Speed controller supporting concurrent device and host operation. As a device, it handles up to six endpoints (including 256-byte EP1); as a host, it manages up to 256-byte packets, automatic device connect/disconnect detection, and IN/OUT token handshake-enabling standalone USB peripheral control without external hub ICs.

How does the dual Flash architecture improve firmware update reliability?

MainFlash stores application code and executes directly; WorkFlash provides a protected, independently secured 32 KB region for storing firmware update images or critical runtime data. This separation prevents corruption of active code during over-the-air updates and allows atomic swap operations-ensuring fail-safe recovery if power loss occurs mid-update.

What low-power modes are available and which peripherals remain active?

Six modes include SLEEP (CPU stopped, peripherals active), TIMER (RTC running), STOP (all clocks halted except sub-clock), and two Deep Standby variants (with/without SRAM retention). In STOP mode, only RTC, watchdog, and external interrupt pins retain functionality; Deep Standby RTC keeps calendar, 32-byte backup registers, and VBAT-powered oscillation circuit active for ultra-low leakage wake-up.
