Toshiba (News - Alert) America Electronic Components, Inc., a company specializing in electronic components, has launched a new 32-bit microcontroller or MCU, the TMPM380 capable of delivering improved operating characteristics, including better energy efficiency and more precise control.
Company officials said that the new TMPM380 MCU was specifically designed for the digital control of high-current circuits commonly found in industrial or appliance applications.
Powered by a 40 MHz ARM (News - Alert) Cortex-M3 processor core, Toshiba's TMPM380 is designed to provide higher performance than the 8- and 16-bit MCUs.
"With the TMPM380 MCU, we are bringing a higher level of digital processing to industrial and appliance applications at a lower price point," Andrew Burt, vice president of the Imaging and Communications Marketing Group in the ASSP Business unit at TAEC said.
"By implementing the TMPM380 MCU in their designs, engineers will be able to develop cookers, pumps, compressors, motors or any system controlled by inverters or discrete power devices with better operating characteristics or additional features without increasing system cost," Burt added.
As stated, Toshiba's TMPM380 MCU uses a specialized pulse-width modulation or PWM circuit, which can generate three-phase control for motor circuits or a 16-bit programmable pulse generator control for circuits employing power semiconductors such as insulated gate bipolar transistors or field-effect transistors. The MCU has an on-board 12-bit analog/digital converter that can synchronize with the PWM unit to read back system state at critical times. The device also has several safety and fault tolerance features, including software support of the IED 60730B safety standard and oscillator frequency and low voltage detectors.
Additionally, the TMPM380 uses zero-wait state FLASH and SRAM that assures latency time does not vary in unpredictable ways. With this as the key benefit, designers can develop applications that require deterministic timing. In addition, the MCU's Cortex-M3 core offers fast interrupt response, typical in applications where real-time operating systems need to quickly adapt to varying inputs, such as with appliances.
Company officials mentioned that the engineering samples of TMPM380 MCU are available with immediate effect and the pricing starts with the TMPM382FSFG - 64K Flash / 8K SRAM at $1.90 per unit in 10,000 unit quantities.
