ARM microcontroller MKE02Z64VLH4R Mcu 64K flash 40Mhz 64LQFP electronic component

General description

The GD32L233xx device belongs to the value line of GD32 MCU family. It is a new 32- bit general-purpose microcontroller based on the ARM® Cortex®-M23 core. The CortexM23 processor is an energy-efficient processor with a very low gate count. It is intended to be used for microcontroller and deeply embedded applications that require an areaoptimized processor.

The processor delivers high energy efficiency through a small but powerful instruction set and extensively optimized design, providing high-end processing hardware including a single-cycle multiplier and a 17-cycle divider.

The GD32L233xx device incorporates the ARM® Cortex®-M23 32-bit processor core operating at up to 64 MHz frequency with Flash accesses 0~3 wait states to obtain maximum efficiency. It provides up to 256 KB embedded Flash memory and up to 32 KB SRAM memory. An extensive range of enhanced I/Os and peripherals connected to two APB buses. The devices offer one 12-bit ADC and two comparators, up to four general 16-bit timers, two basic timers, and a 32-bit low power timer, as well as standard and advanced communication interfaces: up to two SPIs, three I2Cs, two USARTs, two UARTs, an I2S, and an LPUART.

The device operates from a 1.71 to 3.63 V power supply and available in -40 to +85 °C temperature range. Several power saving modes provide the flexibility for maximum optimization between wakeup latency and power consumption, an especially important consideration in low power applications.

The above features make the GD32L233xx devices suitable for a wide range of applications, especially in areas such as industrial control, motor drives, user interface, power monitor and alarm systems, consumer and handheld equipment, gaming and GPS, E-bike and so on.
