Toshiba microcontrollers support USB functionality
A Toshiba Electronics Europe product story
Edited by the Electronicstalk editorial team Jan 19, 2010
Toshiba Electronics Europe (TEE) has expanded its range of 32-bit ARM9 microcontrollers that combines integrated graphics capabilities with a comprehensive set of on-board peripherals and interfaces.
The TMPA900CMXBG low-power device adds USB Host functionality, USB Device support and features that simplify compliance with the IEC60730 Class B home appliance safety standards.
Based on the low-power 32-bit ARM926EJ-S core operating at up to 200MHz, the TMPA900CMXBG simplifies the design and reduces the component count of embedded systems that need to combine HMI (human machine interface) support with multiple connectivity options.
This includes a variety of industrial, consumer and multimedia designs, plus home appliances such as washers, dryers and refrigerators.
In the case of home appliances, an integrated oscillation frequency detector (OFD) facilitates hardware monitoring of the CPU clock to enable compliance with the requirements of safety standard IEC60730 (Class B).
Toshiba's latest microcontroller features an LCD controller for STN/TFT colour displays up to a maximum of 1024 x 768 pixels, a touch-screen interface and an image process accelerator that provides on-chip scaling, filtering and image blending at resolutions up to 800 x 480 pixels.
The USB 2.0 Host interface and high-speed (480Mbps) USB 2.0 Device interface join connectivity options such as SPI, UART, I2C, I2S and a connection for a CMOS image sensor.
Built-in peripherals include an eight-channel 10-bit ADC, a six-channel 16-bit timer, a watchdog timer, a real-time clock and a melody/alarm generator.
As well as 16Kbytes of boot ROM and 32Kbytes of embedded RAM for program, data and display memory, the TMPA900CMXBG has a built-in memory controller supporting external SDR SDRAM and DDR LVCMOS_I/O-type SDRAM.
An SD host controller is compatible with high-speed mode SD cards with capacities to 32Gbytes.
The TMPA900CMXBG is supplied in a 289-pin BGA package and offers 91 general-purpose I/O pins.
Clock speeds of up to 200MHz are supported at temperatures between -20C and +85C.
