STM32 section

The EVALKITST7590-Q1 is equipped with an STM32F103RGT7 device, a medium-density

ARM® based 32-bit microcontroller.

For complete information on device characteristics, please refer to Part 3 of Section 13:

References on page 63.

On the EVALKITST7590-Q1 board, the STM32F103RGT7 microcontroller can be used for

following purposes:



Handle the ST7590 device through direct connections



External access through several interface types: USB, SPI, I2C, USART, JTAG



Store and read data to/from an external µSD card



Develop test functions

On the EVALKITST7590-Q1, the STM32 microcontroller shares its VDD supply voltage with

the VDDIO digital supply of the ST7590 device.

A dedicated 8 MHz crystal has been provided with two suitable load capacitors according to

recommendations in Part 4 of Section 13: References on page 63.
