Toshiba Cortex-M3 chip CAN, USB and Ethernet
Toshiba Electronics Europe has introduced a series of ARM Cortex-M3 microcontrollers, its first to incorporate Ethernet, CAN and USB host and device interfaces.
With Cortex-M3 cores 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.
There are two independent analogue-to-digital converters (ADCs) with conversion times of 1µs or 0.5 µs in interleaved mode.
According to the supplier, this will meet the requirements of barcode readers.
The chip’s multi-purpose timer (MPT) combines three-phase PWM control with an ADC trigger making the new devices ideal for motor control applications.
On-chip memory are ROM options of either 512kbyte or 256kbyte using the firm’s Nano Flash technology, which runs at 80MHz without wait states and allows for very high-speed programming.
Integrated RAM of up to 128kbyte provides capacity for key IP, and a 32-channel DMA controller increases the overall system performance.
All of the new microcontrollers feature two10-bit digital-to-analogue converter (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.
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.
Toshiba’s TMPM369Fxxx microcontrollers are available in LQFP-144 and FBGA-176 package options....RESOURCES
