Semiconductor device supplier GigaDevice launched China’s first GD32H737/757/759 series of ultra-high-performance microcontrollers based on the Arm Cortex-M7 core. The new product portfolio includes 3 series with a total of 27 models, providing 176-pin and 100-pin BGA packages, 176-pin, 144-pin and 100-pin LQFP packages, and five options. Samples and development board applications will be opened at the end of May. 10 Formal mass production and supply from January.
It is learned from the official that GD32H7 can be widely used in various applications such as digital signal processing, motor frequency conversion, power supply, energy storage system, drones, audio and video, graphics and images, and is also suitable for scenarios such as machine learning and artificial intelligence.
GD32H7 series MCU adopts 600MHz Arm Cortex-M7 high-performance core based on Armv7E-M architecture, 6-stage superscalar pipeline architecture supporting branch prediction, high-bandwidth AXI and AHB bus interface, built-in advanced DSP hardware accelerator and double-precision floating-point unit (FPU), as well as hardware trigonometric function accelerator (TMU) and filter algorithm accelerator (FAC), the working performance at the highest frequency can reach 1552 DMIPS, and the CoreMark score is 2888 points.
GD32H7 series MCU is equipped with 1024KB to 3840KB on-chip Flash and 1024KB SRAM, including 512KB configurable ultra-large tightly coupled memory (ITCM, DTCM), with 64KB L1-Cache cache, effectively improving CPU processing efficiency and real-time performance. External bus expansion (EXMC) supports access to various off-chip memories such as SDRAM, SRAM, ROM, NOR Flash, and NAND Flash, and has a built-in macrocell ETM that can track instructions and data in real-time.
GD32H7 series MCU has added a large number of general-purpose peripheral resources, including 8 U(S)ARTs, 4 I2Cs, 6 SPIs, 4 I2Ss, 2 SDIOs and 2 eight-wire OSPIs (downward compatible with four-wire system QSPI), etc.; use 1.71V~3.6V power supply, support advanced power management and provide three power supply modes (LDO / SMPS / direct power supply) and five low power consumption modes.
