GD32H757xx Datasheet

3.45.

Hardware semaphore (HWSEM)



32 semaphores.



An interrupt is generated when a semaphore is unlocked.



Semaphore is unlocked only when MID[3:0] and PID[7:0] are matched.

Hardware semaphore (HWSEM) provides a non-blocking mechanism to ensure the

synchronous of processes. HWSEM realizes 32 semaphores in an atomic way, supporting

semaphore write lock and read lock, and semaphore can only be unlocked when bus master

and process are matched.

Universal serial bus high-speed interface (USBHS)



Supports USB 2.0 Host mode at High-Speed(480Mb/s), Full-Speed(12Mb/s) or Low-

Speed(1.5Mb/s).



Supports USB 2.0 device mode at High-Speed(480Mb/s) or Full-Speed(12Mb/s).



Supports OTG protocol with HNP (Host Negotiation Protocol) and SRP (Session

Request Protocol).

USB High-Speed (USBHS) controller provides a USB-connection solution for portable

devices. USBHS supports both host and device modes, as well as OTG mode with HNP (Host

Negotiation Protocol) and SRP (Session Request Protocol). USBHS contains an embedded

USB PHY internal which can be configured as High-Speed or Full-Speed. USBHS supports

all the four types of transfer (control, bulk, Interrupt and isochronous) defined in USB 2.0

protocol. There is also a DMA engine operating as an AHB bus master in USBHS to speed

up the data transfer between USBHS and system. For Full-Speed operation, battery charging

detection (BCD), attach detection protocol (ADP), and link power management (LPM) are

also supported.

3.47.

Debug mode



JTAG and SWD Debug Port.

The GD32H757xx series provide a large variety of debug, trace and test features. They are

implemented with a standard configuration of the Arm® CoreSight™ module together with a

daisy chained standard TAP controller. Debug and trace functions are integrated into the

ARM® Cortex®-M7. The debug system supports serial wire debug (SWD) and trace functions

in addition to standard JTAG debug.

3.48.

Package and operation temperature



LQFP144 (GD32H757Zx), BGA100\LQFP100 (GD32H757Vx).
