Product details
Overview
CY9BF367NBGL-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, and integrated motor control peripherals including QPRC, multi-function timers, and LIN/UART/CSIO/I²C interfaces. It operates up to 160 MHz and supports deep low-power modes for industrial motor drives and embedded controllers.
For engineers reviewing the CY9BF367NBGL-GE1 datasheet, CY9BF367NBGL-GE1 pinout, CY9BF367NBGL-GE1 application, or CY9BF367NBGL-GE1 equivalent, key selection criteria include Flash/SRAM partitioning (MainFlash + WorkFlash), dual USB capability (device + host), 24-channel 12-bit ADC with FIFO, 2-channel 12-bit R-2R DAC, and 5V-tolerant GPIOs in 120-pin LQFP package.
Technical Context
The CY9BF367NBGL-GE1 implements the ARM Cortex-M4F r0p1 core with hardware FPU and DSP instruction support, enabling real-time motor control algorithms and signal processing. Its memory subsystem includes two independent Flash banks (1024 KB MainFlash + 32 KB WorkFlash) with configurable wait states and built-in accelerator for zero-wait access up to 72 MHz.
Peripheral integration targets motion control systems: dual QPRC channels for encoder position feedback, 8-channel base timer with PWM/PPG/PWC modes, 2-unit multi-function timer with 6-channel A/D activation compare, and dedicated DTIF interrupt for emergency stop - all synchronized to a common clock domain with sub-6.25 ns resolution.

| Clock Supervisor (CSV) | Monitors external crystal frequency deviation and stoppage using internal CR clocks - triggers reset/interrupt before timing faults propagate to control loops |
| Low-Power Modes | Six modes including Deep Standby RTC (with/without RAM retention) and STOP - reduces current to ≤1.2 µA while preserving RTC, backup registers, and wake-up sources |
Applications
| Industrial Motor Drive | Automotive Body Control Module |
|---|---|
|
Use Scenario: Closed-loop field-oriented control (FOC) of 3-phase BLDC motors in HVAC compressors and industrial pumps. IC Role / Device Role / Timing Role: Real-time execution of FOC algorithm, PWM waveform generation, encoder position capture via QPRC, and ADC sampling synchronization. Use Value: 160 MHz core + 0.5 µs ADC + DTIF interrupt ensures <10 µs current loop response time and safe torque shutdown within 2 µs of fault detection. |
Use Scenario: Central body controller managing door locks, window lifts, lighting, and LIN-connected sensors in entry-level vehicles. IC Role / Device Role / Timing Role: LIN master node coordinating slave devices, UART-based diagnostics, and multi-channel PWM for LED dimming and motor actuation. Use Value: Integrated LIN 2.1 controller + 8 UART/CSIO channels + 5V-tolerant I/O eliminates level-shifting components and reduces BOM count by ≥3 ICs. |
| Smart Energy Metering | Programmable Logic Controller (PLC) I/O Module |
|
Use Scenario: DIN-rail mounted meter with harmonic analysis, tamper detection, and secure firmware updates via USB host. IC Role / Device Role / Timing Role: High-precision ADC acquisition, CRC32 integrity checking, USB host for field update, and RTC-backed event logging. Use Value: Dual Flash banks allow seamless firmware upgrade while maintaining metering accuracy; 32-byte backup registers retain calibration constants across power loss. |
Use Scenario: Modular PLC digital I/O expansion unit with isolated inputs/outputs and deterministic communication over RS-485 (via UART). IC Role / Device Role / Timing Role: High-speed GPIO scanning, hardware flow control (RTS/CTS), watchdog supervision, and dual watchdog (HW/SW) for fail-safe operation. Use Value: Hardware watchdog clocked by 100 kHz CR oscillator remains active in STOP mode, ensuring guaranteed recovery from brown-out events without external circuitry. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RA6M4 (R7FA6M4AF3CFP) | ARM Cortex-M4F @ 200 MHz, 1 MB Flash, 384 KB SRAM, no integrated QPRC or LIN, USB HS support | Lacks dedicated motor control peripherals (QPRC, DTIF, multi-function timer); requires external encoder interface and LIN transceiver | Preferred for high-throughput data logging or HMI applications where USB HS and larger SRAM outweigh motor-specific features |
| S32K144 (S32K144HAT0MLHT) | ARM Cortex-M4F @ 112 MHz, 512 KB Flash, 128 KB SRAM, ASIL-B ready, CAN FD, no USB host | Includes CAN FD and functional safety features but omits USB host, WorkFlash, and DSTC - targets automotive ECU rather than industrial motion control | Chosen when ISO 26262 compliance and CAN FD networking are mandatory, and USB host or encoder-integrated timing is not required |
Compared with RA6M4 and S32K144, CY9BF367NBGL-GE1 uniquely combines USB device/host, QPRC, LIN, and WorkFlash in a single 120-pin LQFP - reducing external component count and simplifying firmware update architecture for cost-sensitive industrial motor controllers.

FAQ
What is the maximum operating frequency and supported voltage range for CY9BF367NBGL-GE1?
The CY9BF367NBGL-GE1 operates at up to 160 MHz with a supply voltage range of 2.7 V to 5.5 V on VCC. USB I/O requires 3.0–3.6 V on USBVCC when active, and VBAT supports 2.7–5.5 V for RTC backup. All specifications are validated across the industrial temperature range (−40°C to +105°C) per datasheet Section 12.2.
Does CY9BF367NBGL-GE1 support USB device and host functionality simultaneously?
No - the USB interface supports device mode and host mode, but not concurrent operation. The USB controller uses a single PHY and must be configured at boot or runtime for one role. Switching between modes requires reinitialization and is not intended for dynamic toggling during normal operation.
How is Flash memory organized, and what security features protect firmware?
Flash is split into 1024 KB MainFlash and 32 KB WorkFlash, each with independent security lock bits. Code protection disables read/write/erase access via SWD and serial interfaces. WorkFlash allows background firmware updates while MainFlash executes code, enabling robust over-the-air or USB-based field upgrades.
What debug interfaces does CY9BF367NBGL-GE1 provide, and are they available in all power modes?
It supports Serial Wire JTAG Debug Port (SWJ-DP) and Embedded Trace Macrocell (ETM) for full-cycle debugging and instruction tracing. Debug access is disabled in STOP and Deep Standby modes but remains active in SLEEP, TIMER, and RTC modes - allowing breakpoints and register inspection during low-power operation with CPU halted.
