Toshiba added to its range of 32-bit ARM9 microcontrollers with a device that has USB host functionality, USB device support and features designed to 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 combines HMI (human machine interface) support with USB functionality for industrial, multimedia designs and home appliances.
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).
The MCU has 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 8-channel 10-bit ADC, a 6-channel 16-bit timer, a watchdog timer, a real time clock and a melody/alarm generator.
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 -20ºC and +85ºC.
