Infineon Technologies CY9BF368NBGL-GE1

Overview

CY9BF368NBGL-GE1 from Cypress Semiconductor is a 32-bit ARM® Cortex®-M4F microcontroller with FPU, 1024 KB Flash, 128 KB SRAM (64+32+32), USB 2.0 Full-Speed Device/Host, 24-channel 12-bit ADC, and motor control timers. It operates up to 160 MHz, supports LIN 2.1, I²C, UART, CSIO, SD card interface, and six low-power modes - deployed in industrial motor drives and embedded motion controllers.

For engineers reviewing the CY9BF368NBGL-GE1 datasheet, CY9BF368NBGL-GE1 pinout, CY9BF368NBGL-GE1 application, or CY9BF368NBGL-GE1 equivalent, key selection criteria include integrated motor timer units with dead-time insertion, dual watchdogs (hardware + software), VCC range of 2.7–5.5 V, RTC with calendar and alarm, and QPRC for encoder position feedback in closed-loop systems.

Technical Context

The CY9BF368NBGL-GE1 implements an ARM Cortex-M4F core (r0p1) with hardware FPU and DSP extensions, enabling real-time floating-point math for motor vector control algorithms. Its memory subsystem includes two independent Flash banks (MainFlash + WorkFlash) with configurable wait states and built-in accelerator for zero-wait access up to 72 MHz.

Peripheral integration targets motion control: dual Multi-function Timers provide PWM, PPG, input capture, A/D activation, and DTIF emergency stop; QPRC tracks quadrature encoder signals; and the DSTC offloads CPU for high-throughput data movement between ADC, RAM, and peripherals without software intervention.

Key Specifications

FAQ

What is the maximum operating frequency and voltage range for CY9BF368NBGL-GE1?

The CY9BF368NBGL-GE1 operates at up to 160 MHz with a VCC supply range of 2.7 V to 5.5 V. Its Flash memory achieves zero-wait-state access up to 72 MHz; above that, the built-in Flash Accelerator maintains equivalent performance. USB I/O requires USBVCC at 3.0–3.6 V when active, but reverts to full VCC range when used as GPIO.

Does CY9BF368NBGL-GE1 support LIN communication, and what version is implemented?

Yes, CY9BF368NBGL-GE1 supports LIN 2.1 protocol in both master and slave modes via its Multi-function Serial Interface (CSIO/LIN channel). It includes hardware-level break field generation (13–16 bit), delimiter control (1–4 bit), and automatic error detection (parity, framing, overrun), eliminating software overhead for LIN frame assembly and validation.

How many independent timer units are available for motor control, and what critical functions do they provide?

CY9BF368NBGL-GE1 integrates two dedicated Multi-function Timer units, each offering 6 output compare channels, input capture, A/D activation triggers, and waveform generation. Key motor-specific functions include dead-time insertion for half-bridge gate driving, DTIF (motor emergency stop) interrupt, and synchronized PWM/PPG outputs - all implemented in hardware without CPU intervention.

Is there hardware support for quadrature encoder interfacing, and how is it implemented?

Yes, CY9BF368NBGL-GE1 includes two Quadrature Position/Revolution Counter (QPRC) channels. Each provides 16-bit position and revolution counters with independently configurable edge detection on AIN/BIN/ZIN pins. The ZIN input resets the position counter on index pulse, enabling absolute position tracking - essential for servo and stepper motor applications requiring precise commutation timing.
