San Jose, Calif.Designed for use in devices requiring multimedia display capability, the TMPA910CRAXBG microcontroller (MCU) from Toshiba America Electronic Components Inc. (TAEC) combines a powerful 32-bit ARM926EJ-S processor core with an LCD controller, LCD data processor, efficient 7-layer multiple bus (multibus) system, and numerous other commonly used peripherals.
Target applications for the TMPA910CRAXBG are broad and include electronic dictionaries and other electronic learning assistance devices, toys, industrial and medical devices, personal navigation devices, handheld media players and control panels for home appliance, automation and security applications.
Based on an ARM926EJ-S CPU operating at up to 200-MHz, the TMPA910CRAXBG features a built-in LCD controller with support for TFT and STN display resolutions up to 1024 by 768 pixels and an LCD data processor that provides image scaling, filtering and blending functions and offers real-time video processing for video at up to 30 frames per second. The TMPA910CRAXBG MCU also integrates a CMOS image sensor interface to simplify implementation of an image capture function in embedded devices.
The TMPA910CRAXBG MCU uses a 7-layer multi-bus architecture so both code and data can be transferred quickly and efficiently. Even when the clock speed is lowered to save power, the multibus system can still operate independently with a minimal increase in overhead.
The ARM926EJ-S 32-bit RISC CPU core offers flexible size instruction and data caches and a memory management unit (MMU). It also provides separate instruction and data AMBA AHB interfaces particularly suitable for multi-layer AHB based systems. The ARM926EJ-S processor implements the ARMv5TEJ instruction set and includes an enhanced 16 x 32-bit multiplier capable of single cycle MAC operations. The ARMv5TEJ instruction set includes 16-bit fixed point DSP instructions to enhance performance of many signal processing algorithms and applications as well as supporting Thumb and Java byte code execution.
Additional peripherals supported by the TMPA910CRAXBG include a variety of functionality and connectivity solutions, such as SPI, UART, I²C, USB, a melody/alarm generator, RTC and a power management circuit.
The MCU offers 56 Kbytes of RAM for program, data and display memory, an SDR and DDR SDRAM memory controller, NAND flash interface, JTAG interface, and a high-speed (480-Mbit/s) USB device controller. The TMPA910CRAXBG also integrates an SD memory host controller that supports high-speed mode for interaction with SD memory cards with up to 32-GB capacities. The device is available in a 361-pin FPGA package.
Pricing: $10 per unit in 10,000 unit quantities.
Availability: Engineering samples in April, with mass production scheduled for the third quarter of 2008.
