Reference board for TZ1200 App-Lite processor supports wearable prototypes

To support development of wearable devices and IoT applications, Toshiba Electronics Europe has introduced a reference design board for the TZ1200 App-Lite graphics processor. The reference board forms part of a development platform ecosystem that allows designers to rapidly configure and develop wearable devices and IoT applications, says Toshiba.

The reference design board is a fully-featured design that includes the main components needed to rapidly build and debug prototypes. It is based on a low power TZ1200 App-Lite graphics processor, based on a 32-bit ARM Cortex-M4F processor, capable of operating at 96/120MHz with just 70-microA/MHz current consumption in active mode.

The TZ1200 includes embedded 2D graphics accelerators (GFX) that provide a powerful platform for alpha-blending, drawing, rotating, texturing and resizing images as well as performing on-the-fly colour conversion. The graphic accelerators together with an optimised bus structure, removes almost all of the load on the processor and, according to Toshiba, contributes significantly to further power saving. 

The reference design board also incorporates a THGBMHG6C1L that provides 8Gbyte of e•MMC flash memory for data storage and application program booting. The low power TC35679 Bluetooth low energy (BLE 4.2) single-chip device and integrated PCB antenna provide wireless connectivity for the system.  

Although provided in a small form factor, that measures 50 x 4omm, the TZ1200 board incorporates multiple connectors for ease of access and expansion. The display connector carries MIPI DSI, parallel and SPI signals, allowing the user the flexibility to connect round, rectangular or customised displays. The TZ1200’s analogue front-end (AFE) combines a 24-bit delta-sigma ADC, 12-bit ADC, 12-bit DAC and an LED DAC, all available on the AFE connector. This can be used, for example, to interface to optical heart rate or ECG sensors. Another expansion options is a connector that provides GPIO, ADC, UART, I2C, SPI signals allowing the connection of further external components for quick prototyping, e.g. Arduino shields, via a simple conversion board. 

The TZ1200 board can be either battery-powered or use power supplied via a micro USB connector to the on-board voltage regulator.

Beside product prototyping the board can be used as software development platform. Free software options, including an advanced graphics library, graphics drivers, graphics examples, CMSIS drivers and Bluetooth low energy drivers, are available. Users also benefit from access to Toshiba’s online App-Lite Developer Zone that includes a range of information for developers and software downloads.

The TZ1200 reference board is shipping now.
