GigaDevice’s Entry-Degree Microcontroller Vary Will get an Arm Cortex-M23 Pace Increase within the GD32C231

Semiconductor agency GigaDevice has introduced a brand new entry in its microcontroller vary for individuals who have to steadiness efficiency and value on the entry-level finish of the spectrum: the GD32C231 collection, that includes Arm Cortex-M23 processor cores.

“With over two billion MCUs [Microcontroller Units] shipped,” the corporate boasts, “GigaDevice leverages its mature provide chain and innovation to push previous the restrictions of conventional entry-level chips. The GD32C231 microcontroller collection brings highly effective integration, wide-voltage industrial-grade design, and a whole improvement ecosystem — all at aggressive costs. It redefines what’s attainable on the entry-level tier.”

Sitting, as the corporate says, on the decrease finish of the microcontroller spectrum, the GD32C231 is constructed round a single 32-bit Arm Cortex-M23 core working at as much as 48MHz. Relying on mannequin, that comes paired with 12kB of low-power static RAM (SRAM) and between 32–64kB of program flash, all of which helps error correction code (ECC), in bundle codecs together with TSSOP20, QFN28, and LQFP48. The transfer to the brand new Cortex-M23 offers, the corporate says, round a ten p.c efficiency uplift over its previous-generation Cortex-M0+ components.

Peripherals on the brand new chips embrace a 12-bit analog to digital converter (ADC) with 13 exterior channels and two inside comparators, as much as 4 general-purpose 16-bit timers plus one superior timer, two high-speed SPI interfaces supporting quad-SPI at as much as 24Mbps, two I2C buses with Quick Mode+ assist for 1Mbps communications, an I2S interface, and three UARTs working at as much as 6Mbps, plus an built-in three-channel direct reminiscence entry (DMA) controller.

There are as much as 45 general-purpose enter/output (GPIO) pins out there within the 48-pin bundle variations, with claimed electrostatic safety for as much as 8kV contact and 15kV in air, whereas the chips lengthen their industrial capabilities with assist for 1.8–5.5V operation, temperatures between -40—105°C (-40–221°F), and a 2.6µs wake-up time from a 5µA deep-sleep state.

Extra data on the brand new chips is on the market on the GigaDevice web site.
