Product details
Overview
CY9BF368RBGL-GK7E1 from Cypress Semiconductor (now Infineon) is a 32-bit ARM® Cortex®-M4F microcontroller with FPU, 1024 KB Flash, 128 KB SRAM, USB 2.0 Full-Speed device/host interface, 24-channel 12-bit ADC, and motor control timers. It operates up to 160 MHz and supports LIN, I²C, UART, CSIO, and SD card interfaces for industrial motor control and embedded automation systems.
For engineers reviewing the CY9BF368RBGL-GK7E1 datasheet, CY9BF368RBGL-GK7E1 pinout, CY9BF368RBGL-GK7E1 application, or CY9BF368RBGL-GK7E1 equivalent, key selection criteria include real-time motor timing resolution (6.25 ns), dual watchdog architecture (hardware + software), VCC range (2.7–5.5 V), RTC with leap-year support, and QPRC encoder interface for position feedback in closed-loop drives.
Technical Context
The CY9BF368RBGL-GK7E1 implements an ARM Cortex-M4F core (r0p1) with integrated FPU and DSP instructions, enabling deterministic floating-point math for motor vector control algorithms. Its memory subsystem includes two independent Flash banks (MainFlash + WorkFlash) and three SRAM blocks (SRAM0–SRAM2), each mapped to distinct bus domains for concurrent code/data access and interrupt latency optimization.
Peripheral integration targets real-time motion control: dual Multi-function Timers with dead-time insertion, DTIF emergency stop, A/D activation compare, and waveform generation; plus Quadrature Position/Revolution Counters (QPRC) with configurable AIN/BIN/ZIN edge detection and 16-bit counters per channel.

Equivalent & Alternatives
The following parts are listed as comparable options for similar motor control microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RA6M4 Group (R7FA6M4AF3CFB) | ARM Cortex-M4F @ 200 MHz, 1 MB Flash, 384 KB SRAM, no QPRC, integrated Ethernet MAC | Lacks dedicated quadrature encoder counter; requires software-based position tracking or external QEI | Preferred when Ethernet connectivity or larger RAM is required over native encoder interface |
| STM32H743VI | ARM Cortex-M7 @ 480 MHz, 2 MB Flash, 1 MB SRAM, FMC, no LIN, no built-in USB host | Higher performance but lacks LIN protocol stack and USB host capability; requires external transceiver for LIN | Chosen for compute-intensive vision or AI-edge tasks where LIN/USB host are handled externally |
Compared with RA6M4 and STM32H743VI, the CY9BF368RBGL-GK7E1 offers tighter integration for cost-sensitive motor control: native QPRC, LIN 2.1, USB device/host, and 6.25 ns timer resolution - all in a single 120-pin LQFP without external components.

FAQ
What is the maximum operating frequency and does it require external clock conditioning?
The CY9BF368RBGL-GK7E1 operates up to 160 MHz using its internal Main PLL, which accepts a 4–48 MHz external crystal on CLKIN. No external clock conditioner is needed - the PLL provides jitter-suppressed core clock, and the Clock Supervisor monitors external oscillator stability with automatic reset on failure.
Does this MCU support secure firmware updates and code protection?
Yes. The device includes Flash security functions for both MainFlash and WorkFlash, preventing unauthorized read-out or reprogramming. Code protection is enforced at boot and can be configured per Flash sector. Unique 41-bit ID enables device-specific cryptographic binding in secure boot implementations.
Can the USB interface operate in both device and host modes simultaneously?
No. The USB controller supports either device or host mode per power-on configuration - not concurrent operation. Mode selection is controlled by the USBMODE bit in the USBPHYCR register at reset; switching requires full reset and reinitialization of the USB PHY and controller.
What low-power modes retain RTC functionality while minimizing current draw?
The Deep Standby RTC mode retains full RTC/calendar operation with leap-year support while drawing only ~1.2 µA (typ.) from VBAT. RAM retention is optional - disabling it reduces current further. This mode maintains timekeeping through main power loss using the 32.768 kHz sub-clock oscillator and backup registers.
