Microprocessor combines 32-bit ARM processor with graphics control and processing functionality to simplify multimedia applications

Based on the ARM926EJ-S CPU core operating at up to 200MHz, the new TMPA910CRAXBG uses a seven layer multibus architecture. This architecture significantly improves performance compared to other devices operating at similar processor speeds. The built-in LCD controller offers support for TFT and STN display sizes up to 1024 x 1024 pixels. An LCD data processor accelerator delivers image scaling, filtering and blending functions and offers real time processing for movies at speeds up to 30 frames per second.

The new TMPA910CRAXBG has a CMOS image sensor interface that simplifies the implementation of applications requiring image capture. A touchscreen interface further reduces the need for external components in man machine interface (MMI) designs. Additional connectivity includes SPI, UART, I2C, I2S, and a high-speed USB device (480Mbps).

Toshiba has incorporated 56Kbytes of built-in embedded RAM for program, data and display memory, Boot ROM, and a memory controller that supports SDR and DDR SDRAM. Up to 2.5Gbytes of linear access space can be addressed. An SD host controller supports high-speed mode SD cards with capacities up to 32GB.

The new microprocessor is supplied in a 361-pin FPGA package. Additional built-in peripherals include a 10-bit ADC, a six-channel, 16-bit timer, a watchdog timer, real time clock and alarm functionality.

In addition to extensive software support that includes graphics libraries and embedded operating systems, the new device is supported through the availability of a Starter Kit that will further speed application development and prototyping.
