Infineon Technologies CY9BF564LPMC1-G-JNE2

Overview

CY9BF564LPMC1-G-JNE2 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 PWM, quadrature encoding, and deterministic communication.

For engineers reviewing the CY9BF564LPMC1-G-JNE2 datasheet, CY9BF564LPMC1-G-JNE2 pinout, CY9BF564LPMC1-G-JNE2 application, or CY9BF564LPMC1-G-JNE2 equivalent, key selection criteria include dual Flash architecture with security protection, 8-channel DMA + 128-channel DSTC for off-CPU data movement, 6 multi-function serial interfaces (UART/CSIO/LIN/I²C), RTC with calendar and alarm, and 64-pin LQFP package with 48 high-speed GPIOs and 5 V-tolerant pins.

Technical Context

This MCU implements a tightly coupled Arm Cortex-M4F core (r0p1) with Memory Protection Unit (MPU), NVIC supporting 128 peripheral interrupts across 16 priority levels, and SysTick timer for RTOS scheduling. Its memory subsystem features three independent SRAM banks (SRAM0 on I/D-code bus; SRAM1/SRAM2 on system bus) and dual Flash with accelerator enabling zero-wait-state access up to 72 MHz.

The peripheral set is optimized for motion control: dual 12-bit ADCs (0.5 μs conversion @ 5 V), QPRC for encoder position tracking, Multi-Function Timers with dead-time insertion and DTIF emergency stop, and CAN interface with 32 message buffers operating at up to 1 Mbps. USB supports both device (6 endpoints, 256-byte EP1 buffer) and host (256-byte packet, auto-connect detection) modes.

FAQ

What is the maximum operating voltage and temperature range for CY9BF564LPMC1-G-JNE2?

The device operates from 2.7 V to 5.5 V on VCC and supports industrial temperature range of −40 °C to +85 °C. USB I/O requires 3.0–3.6 V when active, but GPIO operation remains valid across full VCC range. Absolute maximum ratings specify VCC ≤ 6.0 V and junction temperature ≤ 125 °C.

Does CY9BF564LPMC1-G-JNE2 support debug interfaces beyond SWD?

It supports Serial Wire JTAG Debug Port (SWJ-DP) only - combining SWD and JTAG into a single 5-pin interface (SWCLK, SWDIO, NRST, VDD, GND). No UART-based bootloader or SWO trace output is integrated; debugging relies entirely on SWJ-DP with standard CMSIS-DAP or J-Link probes.

How is flash security implemented, and can it be disabled after programming?

Security is enforced via lock bits in Flash configuration registers that prevent read-out of MainFlash and WorkFlash contents. Once enabled, security cannot be disabled without bulk erase - which clears all user code and configuration. The security mechanism is hardware-enforced and independent of software execution state.

Is the RTC calendar function compatible with leap year calculation and battery-backed operation?

Yes, the RTC automatically handles leap years through firmware-assisted calendar logic and retains date/time in Deep Standby RTC mode using VBAT supply. Backup registers (32 bytes) and RTC circuitry remain powered independently, supporting accurate timekeeping for >10 years on a CR2032 coin cell.
