ARM Cortex MCUs with on-chip USB device
22 February 2011
Latest additions to 32-bit ARM Cortex-M3 family to be showcased at Embedded World 2011.
Toshiba Electronics Europe will be using Embedded World to showcase its range of 32-bit ARM Cortex-M3 microcontrollers including the first members of its ARM Cortex-M3 family to feature on-chip full-speed (12Mbps) USB-Device connectivity.
Ideal for applications ranging from industrial control to office automation, the TMPM366 devices are supported by hardware and software tools that will help embedded system designers to speed development and prototyping.
Supplied in LQFP100 packaging, the TMPM366FDFG, TMPM366FYFG and TMPM366FWFG combine on-board Flash program memory with comparatively high levels of on-board RAM.
Respective Flash/RAM capacities are 512Kbytes/64Kbytes, 256Kbytes/48KBytes and 128Kbytes/32Kbytes. An integrated static memory controller allows a further 16Mbytes of external memory to be added to embed designs without the need for additional components.
All of the new microcontrollers incorporate a very fast 12-channel, 12-bit analogue-to-digital converter (ADC) with a conversion time of 1µs, a 10-channel, 16-bit timer and a watchdog timer (WDT).
As well as the single-channel USB-device controller, the devices provide a 2-channel serial bus interface that can be configured for I2C or synchronous mode communication and a 3-channel synchronous serial interface (SSP). A 2-channel general-purpose serial interface allows either UART mode or synchronous mode to be selected, while a built-in single-channel UART offers UART and IrDA 1.0 support.
Toshiba’s TMPM366 range operates with voltages from 2.7V to 3.6V and core frequencies of up to 48 MHz and features an internal oscillator running at 10 MHz.
The ARM Cortex-M3 core allows designers to create highly efficient code and keep power consumption to a minimum. Each device has three levels of standby mode (‘IDLE’, ‘STOP1’ and ‘STOP2’), while a clock gear function can divide the on-chip high-speed clock into 1/1, 1/2, 1/4 or 1/8.
Development support for the new microcontrollers includes evaluation boards and starter kits that allow designers to create and test working programs and key functionality.
