GigaDevice Semiconductor Inc. launches a brand new household of high-performance GD32 32-bit general-purpose microcontrollers (MCUs) for a variety of business functions. The GD32F503/505 32-bit MCUs develop the corporate’s portfolio based mostly on the Arm Cortex-M33 core. Purposes embrace digital energy provides, industrial automation, motor management, robotic vacuum cleaners, battery administration techniques, and humanoid robots.
Constructed on the Arm v8-M structure, the GD32F503/505 sequence provides versatile reminiscence configurations, excessive integration, and built-in safety features, and options a complicated digital sign processor, {hardware} accelerator and a single-precision floating-point unit. The GD32F505 operates at a frequency of 280 MHz, whereas the GD32F503 runs at 252 MHz. Each gadgets obtain as much as 4.10 CoreMark/MHz and 1.51 DMIPS/MHz.
The sequence provides as much as 1024 KB of Flash and 192 KB of SRAM. Customers can allocate code-flash, data-flash, and SRAM location by means of scatter loading based mostly on their particular utility, which permits customers to tailor reminiscence sources in line with their necessities, GigaDevice mentioned.
The GD32F503/505 sequence additionally integrates a set of peripheral sources, together with three analog-to-digital converters with a sampling fee of as much as 3 Ms/s (supporting as much as 25 channels), one quick comparator, and one digital-to-analog converter. For connectivity, it helps as much as three SPIs, two I2Ss, two I2Cs, three USARTs, two UARTs, two CAN-FDs, and one USBFS interface.
The timing system options one 32-bit general-purpose timer, 5 16-bit general-purpose timers, two 16-bit fundamental timers, and two 16-bit PWM superior timers. This interprets into exact and versatile waveform management and sturdy safety mechanisms for functions comparable to digital energy provides and motor management.
The working voltage vary of the GD32F503/505 sequence is 2.6V to three.6 V, and it operates over the industrial-grade temperature vary of -40°C to 105°C. It additionally provides three power-saving modes for maximizing energy effectivity.
These MCUs additionally present high-level ESD safety with contact discharge as much as 8 kV and air discharge as much as 15 kV. Their HBM/CDM immunity is secure at 4,000 V/1,000 V even after three Zap assessments, demonstrating reliability margins that exceed typical requirements for industries comparable to industrial and residential home equipment, GigaDevice mentioned.
As well as, the MCUs present multi-level safety of code and information, supporting firmware upgrades, integrity and authenticity verification, and anti-rollback checks. System safety features a safe boot and safe firmware replace platform, together with {hardware} safety features comparable to person safe storage areas. Different options embrace a built-in {hardware} safety engine integrating SHA-256 hash algorithms, AES-128/256 encryption algorithms, and a real random quantity generator. Every gadget has a novel unbiased UID for gadget authentication and lifecycle administration.
A multi-layered {hardware} safety mechanism is centered round multi-channel watchdogs, energy and clock monitoring, and {hardware} CRC. As well as, the GD32F5xx sequence’ software program check library is licensed to the German IEC 61508 SC3 (SIL 2/SIL 3) for practical security. The sequence supplies a whole security package deal, together with key paperwork comparable to a security handbook, FMEDA report, and security self-test library.
The GD32 MCUs function a full-chain improvement ecosystem. This consists of the free GD32 Embedded Builder IDE, GD-LINK debugging, and the GD32 all-in-one programmer. Software suppliers comparable to Arm, KEIL, IAR, and SEGGER additionally help this sequence, together with compilation improvement and hint debugging.
The GD32F503/505 sequence is offered in a number of package deal varieties, together with LQFP100/64/48, QFN64/48/32, and BGA64. Samples can be found, together with datasheets, software program libraries, ecosystem guides, and supporting instruments. Growth boards can be found on request. Mass manufacturing is scheduled to begin in December. The sequence might be obtainable by means of licensed distributors.
The put up 32-bit MCUs ship industrial-grade efficiency appeared first on EDN.
