Infineon Technologies CY9BF368NPQC-G-JNE2

Overview

CY9BF368NPQC-G-JNE2 from Cypress Semiconductor is a 32-bit ARM® Cortex®-M4F microcontroller in a 120-pin LQFP package, featuring 1024 KB Flash, 128 KB SRAM (64+32+32), USB 2.0 Full-Speed Device/Host, 24-channel 12-bit ADC, dual DAC, motor control timers, and LIN/UART/I²C/CSIO interfaces. It targets real-time embedded motor control and industrial automation systems requiring deterministic timing, analog sensing, and multi-protocol connectivity.

For engineers reviewing the CY9BF368NPQC-G-JNE2 datasheet, CY9BF368NPQC-G-JNE2 pinout, CY9BF368NPQC-G-JNE2 application, or CY9BF368NPQC-G-JNE2 equivalent, key selection criteria include its 160 MHz operation with FPU, dual Flash banks with security, 100 high-speed GPIOs (some 5V-tolerant), RTC with calendar, QPRC for encoder feedback, and six low-power modes including Deep Standby with RAM retention.

Technical Context

The CY9BF368NPQC-G-JNE2 implements an ARM Cortex-M4F core (r0p1) with integrated FPU and DSP extensions, enabling floating-point math and signal processing in real-time motor control loops. Its memory subsystem includes two independent Flash banks (MainFlash up to 1024 KB with accelerator, WorkFlash 32 KB) and three SRAM blocks (SRAM0: 64 KB on I/D bus; SRAM1/SRAM2: 32 KB each on system bus), supporting concurrent code execution and data buffering.

Peripheral integration centers on deterministic motion control: dual Multi-function Timers (each with 3×16-bit free-run timers, 6×output compare, A/D activation, dead-time insertion, and DTIF interrupt), Quadrature Position/Revolution Counters (2×16-bit position + 16-bit revolution counters), and dedicated motor control features like DC chopper waveform generation and PWM synchronization across channels.

Key Specifications

Pinout & Package

This device uses a 120-pin LQFP (14 mm × 14 mm, 0.4 mm pitch) package with exposed thermal pad. Pin functions are defined per mode (GPIO, peripheral, clock, power), and port relocation allows flexible peripheral mapping.

FAQ

What is the maximum operating frequency and does it require external clock conditioning?

The CY9BF368NPQC-G-JNE2 operates at up to 160 MHz using its internal Main PLL, which accepts a 4–48 MHz external crystal (XTAL/EXTAL). No external clock conditioner is needed-the PLL provides stable, low-jitter system clock with dynamic frequency scaling supported via software register control.

How is code protection implemented across the dual Flash banks?

Code protection is implemented via hardware lock bits shared between MainFlash and WorkFlash. Once enabled, read-out and write access to protected regions is blocked; debug access via SWJ-DP is also disabled. Protection granularity supports sector-level locking, allowing secure bootloader storage in MainFlash and encrypted firmware updates in WorkFlash.

Does the device support USB device and host simultaneously?

No-USB device and host modes are mutually exclusive and selected at reset via the USBMODE pin state. The USB interface shares physical transceivers and endpoint resources; simultaneous dual-role operation is not supported. Applications requiring both roles must implement time-multiplexed switching or use external USB OTG solutions.

What peripheral functions are available on the 100 GPIO pins beyond basic digital I/O?

Beyond GPIO, the pins support UART, CSIO, LIN, I²C, ADC inputs, DAC outputs, QPRC inputs (AIN/BIN/ZIN), timer capture/compare outputs, external interrupt requests, and external bus signals (address/data, CS, RD/WR). Port relocation allows remapping most peripheral functions to alternate pins, increasing PCB layout flexibility.
