The mikromedia for PSoC 5LP is a compact development system with lots of on-board peripherals which allow development of hand-held devices with multimedia content. The central part of the system is the 32-bit CY8C5868AXI-LP035 ARM Cortex-M3 microcontroller. The mikromedia for PSoC 5LP features integrated modules such as stereo MP3 codec, TFT 320×240 touch screen display, accelerometer, USB connector, audio connector, MMC/SD card slot, 2 Mbit FRAM, and more. The board features a front-facing reset button, battery charger circuit for Li-Polymer batteries, crystal oscillator, and connection pads for all other available pins. It is compatible with all mikromedia shields (see options below).
A color user manual is included, and example code is available to download. The board comes pre-programmed with a USB bootloader, so you won't have to spend a penny more on external programmers. If you do want to, pins pads are available for using a mikroProg for PSoC 5LP, and the board has a standard 10-pin Cortex Debug connector for third-party hardware debuggers.
All unused microcontroller pins are available via pads along the sides of the board. The board measures 81.2 × 60.5 mm (3.19 × 2.38 inches).

USB power supply You can apply power to the board using the provided Mini-B USB cable. On-board voltage regulators will provide the appropriate voltage levels to each part of the board. The Power LED will indicate the presence of power supply.
Battery power supply You can also power the board using a Li-Polymer battery via the on-board battery connector. An MCP73832 battery charger circuit enables you to charge the battery over USB connection. A red LED indicates when the battery is charging. Charging current is ~250mA and charging voltage is 4.2V DC.
Programming with bootloader For programming the microcontroller, you can use a bootloader program which is pre-installed in the MCU memory. To transfer a bootloader file from a PC to the MCU, you can use the free PSoC Programmer and PSoC Creator applications from Cypress Semiconductor. The board has a mini-USB connector and ships with a cable to connect to your PC.
Programming with external programmer/debugger In case you want to remove the USB bootloader, need to re-install it, or want to perform in-circuit debugging, the microcontroller can be programmed with an external in-circuit programmer/debugger (not included). The board has pads for installing programming headers compatible with the mikroProg for PSoC 5LP. The board also contains a Cortex Debug (SWD) connector that can be used with other external programmers.
Reset Button The board is equipped with a reset button on the LCD side so it can be available to the user if the mikromedia is placed in an enclosure or has a shield attached. In addition, a reset signal can be sent through pin 27 of the side headers.
Crystal Oscillator The board is equipped with a 16MHz crystal oscillator circuit that provides an external clock waveform to the microcontroller OSCO and OSCI pins. This base frequency is suitable for further clock multipliers and ideal for generation of a necessary USB clock, which ensures proper operation of bootloader and your custom USB-based applications. The board also is equipped with a 32.768 kHz crystal provides an external clock for the internal RTCC module.
microSD Card Slot The board contains a microSD card slot for using microSD cards in your projects. It enables you to store large amounts of data externally, thus saving microcontroller memory. microSD cards use Serial Peripheral Interface (SPI) for communication with the microcontroller.
Touch Screen The development system features an MI0283QT-9A TFT 320×240 display covered with a resistive touch panel. Together they form a functional unit called a touch screen. It enables data to be entered and displayed at the same time. The TFT display is capable of showing data in 262,144 different colors. A stylus is sold separately; see the options below.
Audio Module mikromedia for PS0C 5LP features a VS1053 audio controller. This module enables audio reproduction by using stereo headphones connected to the system via the 3.5mm connector CN1. All functions of this module are controlled by the microcontroller over Serial Peripheral Interface (SPI). It supports Ogg Vorbis, MP3, AAC, WMA, FLAC audio files and MIDI.
USB Connection The CY8C5868AXI-LP035 has an integrated USB module which enables you to implement USB communication functionality to the mikromedia board. Connection to a target USB host is achieved with a Mini-B USB connector.
Accelerometer The on-board ADXL345 accelerometer can be used to measure acceleration in three axes: x, y, and z. The accelerometer's function is defined by the program loaded into the microcontroller. Typical usage is to determine screen orientation. Communication between the accelerometer and the microcontroller is performed via the I2C interface. You can set the accelerometer address to 0 or 1 by re-soldering the SMD jumper (zero-ohm resistor) to the appropriate position. This jumper is placed in address 1 position by default.
FRAM The FM25H20-G FRAM module enables the microcontroller to use an additional 2Mbits of ferro-electric non-volatile memory. It is connected to the microcontroller via the Serial Peripheral Interface at up to 40 MHz.
Software Examples The example software is available to download for free (see below), both as ready-to-load compiled code and as source code written in the PSoC Creator. The source codes provide detailed explanatory comments. The demo code package includes:
