Toshiba Electronics has announces an ARM Cortex-M3 microcontroller featuring a single 5V supply. The TMPM380FY is the first in a series of 5V Cortex-M3 devices that will reduce the component count and simplify the development of embedded designs for industrial and white goods applications. Integrated functionality includes the ability to drive motors and control IGBTs, high-accuracy analogue-to-digital conversion, and an Oscillation Frequency Detector. The latter facilitates hardware monitoring of the CPU clock to simplify compliance with the IEC60730 home appliance safety standard.
Toshiba’s new microcontroller is supplied with 256Kbytes of on-chip Flash memory and 16KBytes of on-chip RAM. A 3-channel 16-bit multi-purpose timer provides a function that combines three-phase PWM control with an ADC trigger and a protection circuit. The timer can be used to deliver an externally triggered 16-bit PPG output for IGBT control. Additional on-board functionality includes Power-on-reset and Voltage Detection, an 18 channel high-accuracy 12-bit ADC, a 2-channel encoder input circuit, a watchdog timer and a real time clock. The encoder circuit offers a three-phase sensor input and supports rotation direction and absolute position detection.
Toshiba can supply the new microcontroller in a 100-pin QFP or 100-pin LQFP package. The device has an operating voltage range of 4.5V – 5.5V and a maximum operating frequency of 40MHz. A variety of standby modes help to ensure minimum power consumption when the ARM core is not active.
