PSRAM memory

An 8-Mbit PSRAM (IS66WV51216EBLL-55BLI from Integrated Silicon Solution Inc) is
connected to the FMC interface of the STM32F730I8K6 with 16 bits of data and 18 bits of
addresses (4-Mbit memory accessible).
7.12

Quad-SPI NOR Flash memory

A 512-Mbit Quad-SPI NOR Flash memory (MX25L51245G from MACRONIX) is connected
to Quad-SPI interface of STM32F730I8K6.
7.13

Virtual COM port

The serial interface USART6 is directly available as a virtual COM port of the PC connected
to the ST-LINK/V2-1 USB connector CN1. The virtual COM port settings are configured as:
115200 b/s, 8 bits data, no parity, 1 stop bit, no flow control.
7.14

TFT LCD 240x240 pixels

A 240x240-pixel TFT LCD (FRD154BP2902 from Frida) is connected to FMC data interface
of STM32F730I8K6.
It uses the Sitronix ST7789H2 controller for 262K-color, TFT-LCD graphic type. Display data
are stored in the on-chip display data RAM of 240x320x18 bits. It performs display data
RAM read/write operation with no external operation clock to minimize power consumption.
External PSRAM can also be used to store display data.
LCD_RS signal is used to determine whether bus is carrying data or control/command
registers.
