GD32F405RET6 GD Microcontroller Unit MCU LQFP-64
Introduction
The GD32F405xx device belongs to the connectivity
line of GD32 MCU Family. It is a new 32-bit general-purpose
microcontroller based on the ARM® Cortex®-M4 RISC core with best
cost-performance ratio in terms of enhanced processing capacity,
reduced power consumption and peripheral set. The Cortex®-M4 core
features a Floating Point Unit (FPU) that accelerates single
precision floating point math operations and supports all ARM®
single precision instructions and data types. It implements a full
set of DSP instructions to address digital signal control markets
that demand an efficient, easy-to-use blend of control and signal
processing capabilities. It also provides a Memory Protection Unit
(MPU) and powerful trace technology for enhanced application
security and advanced debug support.
The GD32F405xx device incorporates the ARM®
Cortex®-M4 32-bit processor core operating at 168 MHz frequency
with Flash accesses zero wait states to obtain maximum efficiency.
It provides up to 3072 KB on-chip Flash memory and 192 KB SRAM
memory. An extensive range of enhanced I/Os and peripherals
connected to two APB buses. The devices offer up to three 12-bit
2.6M SPS ADCs, two 12-bit DACs, up to eight general-purpose 16-bit
timers, two 16-bit PWM advanced-control timers , two 32-bit
general-purpose timers, and two 16-bit basic timers, as well as
standard and advanced communication interfaces: up to three SPIs,
three I2Cs, four USARTs and two UARTs, two I2Ss, two CANs, a SDIO,
USB device/host/OTG FS and HS. Additional peripherals as Digital
camera interface (DCI) is included.
The device operates from a 2.6 to 3.6V power supply
and available in –40 to +85 °C temperature range. Three power
saving modes provide the flexibility for maximum optimization of
power consumption, an especially important consideration in low
power applications.
The above features make GD32F405xx devices suitable for a wide
range of interconnection and advanced applications, especially in
areas such as industrial control, consumer and handheld equipment,
embedded modules, human machine interface, security and alarm
systems, graphic display, automotive navigation, drone, IoT and so
on.
