Sound, connectivity & expandibility

A very popular WiFi module labeled as CC3100 enables WiFi connectivity. This module is the complete WiFi solution on a chip: it is a powerful WiFi network processor with the power management subsystem, offering the TCP/IP stack, powerful crypto engine with 256-bit AES support, WPA2 security, SmartConfig™ technology, and much more.

Resource-demanding and complex audio processing tasks can be offloaded from the host MCU by utilizing a dedicated audio CODEC IC, labeled as VS1053B. This IC supports many different audio formats, commonly found on various digital audio devices

The host MCU can be programmed and debugged over the JTAG/SWD compatible
2x5-pin header. A high-precision buffered voltage reference from Microchip is used to provide a very precise voltage reference with no drift, when required.

The FXOS8700CQ, an advanced integrated 3-axis accelerometer and 3-axis magnetometer can detect many different motion-related events.

State of the art power supply, Display & Graphics controller

A high-quality 7" TFT true-color display with a resistive touch panel is the most distinctive feature of the Mikromedia 7. The display has a resolution of 800 by 480 pixels, and it can display up to 16.7M of colors (24-bit color depth). The display module is controlled by the SSD1963 graphics driver IC from Solomon Systech. This is a powerful graphics coprocessor, equipped with 1215KB of frame buffer memory. It also includes some advanced features such as the hardware accelerated display rotation, display mirroring, hardware windowing, dynamic backlight control, programmable color and brightness control, and more.

The Power Supply Unit (PSU) provides a clean and regulated power, necessary for a proper operation of the mikromedia 7 development board. It is equipped with four different power supply inputs, offering all the flexibility that mikromedia 7 needs, especially when used on the field or as an integrated element of a larger system. In the case when multiple power sources are used, an automatic power switching circuit with predefined priorities ensures that the most appropriate will be used.

More connectivity

The microSD card slot allows storing large amounts of data externally, on a microSD memory card. The microSD card detection circuit is also provided on the board.

Ethernet physical layer is provided by the LAN8720A, an RMII 10/100 Ethernet PHY IC from Microchip. This IC has many useful features, including flexPWR® technology with a flexible power management architecture and a support for various low-power modes, compliance with ISO 802-3/IEEE and IEEE802.3/802.3u frame formats, loop-back modes support, auto-negotiation, automatic polarity detection and correction, and so on.

The host MCU is equipped with the USB peripheral module, allowing simple USB connectivity.

The RTC peripheral utilizes a separate power supply source, typically a battery.  To allow continuous tracking of time, mikromedia 7 is equipped with a button cell battery that maintains RTC functionality even if the main power supply is off.
