Toshiba Electronics Europe’s next series of high-performance, low-power 32-bit ARM Cortex-M3 microcontrollers will combine Ethernet, CAN and USB Host and Device connectivity in a single IC. Potential applications for the TMPM369Fxxx family include industrial control systems, barcode readers, motion control, home appliances and solar inverters.
Based around an ARM Cortex-M3 core running at 80MHz, the four microcontrollers in the TMPM369Fxxx series integrate single-channel CAN2.0B, a full-speed USB Host controller, a full-speed USB device controller and a 10/100BASE single-channel Ethernet MAC. Two independent ADCs with conversion times of 1µs – or 0.5 µs in interleaved mode – meet the requirements of barcode readers and other applications requiring ultra-fast conversion. In addition, each of the devices features a special Multi-Purpose Timer (MPT). This MPT combines three-phase PWM control with an ADC trigger making the new devices ideal for motor control applications.
The TMPM369Fxxx series offers on-board ROM options of either 512Kbyte or 256Kbyte using Toshiba’s NANO FLASH technology, which runs at 80MHz without wait states and allows for high-speed programming. Integrated RAM of up to 128Kbyte provides significant on-board capacity for key IP, while a 32-channel DMA controller increases the overall system performance dramatically.
All of the new microcontrollers feature two 10-bit DAC channels and a 2-channel encoder signal input for motor control. Also on-board are a Real Time Clock and an Oscillation Frequency Detector (OFD). The latter provides hardware monitoring of the CPU clock in accordance with the IEC60730 (Class B) safety standard for home appliances. Power on Reset (PoR) functionality is provided as standard.
Featuring on-chip regulators, TMPM369Fxxx microcontrollers are designed for operation from a single 2.7V to 3.6V power supply – or 3.0V to 3.6V when USB is in operation. Clock gearing functionality and ‘IDLE’, ‘STOP1’ and ‘STOP2’ standby modes help to keep power consumption to a minimum.
As well as the CAN, USB and Ethernet functionality the new microcontrollers also have a variety of other interfaces to further speed embedded system design and reduce application component count. These include a 3-channel synchronous serial interface (SSP), 6-channel UART/general-purpose serial I/O (SIO) and three I2C channels. The availability of various Starter Kits and Software packages supports a fast prototyping.
Toshiba’s TMPM369Fxxx microcontrollers are available in LQFP-144 and FBGA-176 package options.
