Toshiba expands ARM-based microcontroller range
Toshiba Electronics
TMPA911CRAXBG
Toshiba Electronics has introduced the TMPA911CRAXBG low-power ARM-based microcontroller, which helps reduce the component count and cost of embedded industrial designs supporting HMI applications.
It enhances the scalability of the Toshiba ARM9 family, helping designers to select the optimum price/performance point for their target applications.
The TMPA911CRAXBG brings together a low-power, 32-bit ARM926EJ-S core running at 150MHz with a variety of integrated peripherals and connectivity options, including comprehensive functions for the control of display panels.
These features, coupled with an operating temperature range of -20C to +85C, make the microcontroller ideal for multimedia and HMI applications targeted at industrial environments.
The TMPA911CRAXBG features a built-in LCD controller, a touch-screen interface and an LCD data-processor accelerator (LCDA).
The LCD controller is suitable for TFT and STN display sizes up to 1024 x 768 pixels.
The LCDA supports resolutions to WVGA (800x480) and delivers image scaling, filtering and blending functions as well as real-time processing for movies.
A CMOS image sensor interface simplifies the implementation of applications requiring image capture.
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.
Connectivity options include SPI, UART, I2C, I2S and a high-speed USB device (480Mbps).
Additional built-in peripherals include a 10-bit ADC, a six-channel 16-bit timer, a watchdog timer, real-time clock and an alarm.
The TMPA911CRAXBG is supplied in a 361-pin FPGA package.
It is pin-compatible and software-compatible with other members of the Toshiba TMPA910 family of 32-bit ARM926EJ-S-based microcontrollers.
The result is true scalability, ensuring an upgrade path to faster processor speeds, improved performance and additional connectivity options - including the addition of SD card interfaces - with minimum system redesign.
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 and reference platform that speed up application development and prototyping.
