GD32F310xx Datasheet

3.13

Universal synchronous asynchronous receiver transmitter

(USART)



Up to two USARTs with operating frequency up to 4.5 MB/s



Supports both asynchronous and clocked synchronous serial communication modes



IrDA SIR encoder and decoder support



LIN break generation and detection



ISO 7816-3 compliant smart card interface

The USART (USART0, USART1) are used to translate data between parallel and serial

interfaces, provides a flexible full duplex data exchange using synchronous or asynchronous

transfer. It is also commonly used for RS-232 standard communication. The USART includes

a programmable baud rate generator which is capable of dividing the system clock to produce

a dedicated clock for the USART transmitter and receiver. The USART also supports DMA

function for high speed data communication.

3.14

Inter-IC sound (I2S)



One I2S bus Interfaces with sampling frequency from 8 KHz to 192 KHz, multiplexed with

SPI0



Support either master or slave mode

The Inter-IC sound (I2S) bus provides a standard communication interface for digital audio

applications by 3-wire serial lines. GD32F310xx contain an I2S-bus interface that can be

operated with 16/32 bit resolution in master or slave mode,

pin multiplexed with SPI0. The

audio sampling frequency from 8 KHz to 192 KHz is supported with less than 0.5% accuracy

error.

3.15

Debug mode



Serial wire debug port (SW-DP)

Debug capabilities can be accessed by a debug tool via serial wire

3.16

Package and operation temperature



LQFP48 (GD32F310Cx), LQFP32 (GD32F310KxT6), QFN32 (GD32F310KxU6), QFN28

(GD32F310GxU6) and TSSOP20 (GD32F310FxP6)



Operation temperature range: -40°C to +85°C for grade 6 devices (industrial level), or –

40 to +105 °C for grade 7 devices

(industrial level)
