- GD32F505 (proper) operates as much as 280MHz and has up 1Mbyte of flash (as much as 192kbyte code flash) and 192kbyte sram
- GD32F503 operates as much as 252MHz and has as much as as much as 1Mbyte of flash (as much as 256kbyte code-flash) and 128kbyte sram.
This compares with 200MHz, 7.5Mbyte flash (2Mbyte read-while-write over-air upgrades) and 1Mbyte sram for the earlier GD32F527.
“These chips function a DSP {hardware} accelerator and a single-precision floating-point unit, [and] obtain as much as 4.10 CoreMark/MHz and 1.51 DMIPS/MHz,” in response to the corporate. “Customers can flexibly allocate code-flash, data-flash, and sram location via scatter loading primarily based on their particular software.”
Peripherals can embrace three 3Msample/s ADCs with as much as 25 channels, a comparator, a DAC, as much as three SPIs interfaces, twin I2S, two I2Cs, three USARTs, two UART, two CAN-FD and one USB.
Timers can embrace one 32bit and 9 16bit or varied sorts. “This upgraded system gives exact and versatile waveform management together with safety mechanisms, tailored for purposes resembling digital energy provides and motor management”, mentioned GigaDevice.
Operation is throughout 2.6 to three.6V (a narrower vary than the sooner …F527) and throughout -40 to +105°C.
Lengthy service life is claimed: “In typical industrial situations, these chips can function repeatedly for over 25 years,” mentioned the corporate. “They assist contact discharge as much as 8kV and air discharge as much as 15kV. Their HBM/CDM* immunity stays secure at 4000V/1000V even after three zap checks, demonstrating margins that exceed standard requirements for trade and residential home equipment.”
Safe boot and secured firmware replace are supported, and there are consumer safe storage areas.
A built-in {hardware} safety engine operates SHA-256 hash, AES-128/256 encryption and true random quantity era, and a singular identifier is supplied.
Useful security is supported by watchdogs, energy monitoring, clock monitoring and {hardware} cyclic redundancy checking.
GD32F5xx collection MCU now even have a IEC 61508 SC3 (SIL 2/SIL 3) purposeful security licensed software program take a look at library.
Bundle choices for F505 sorts embrace LQFP100/64/48, QFN64/48 and BGA64.
The F503 has these package deal choices, in addition to QFN32.
Improvement instruments embrace an IDE, debugger and programmer, and different instruments are availble from Keil, IAR and Segger.
Purposes are foreseen in digital energy provides, industrial automation, motor management, robotic vacuum cleaners, battery administration and robots.
Components are sampling now, with manufacturing scheduled for December.
