Microcontroller Function Terms

Terminology for Microcontroller functions

Servo Control
Servo Control
Servo control technology is necessary to determine motor position. This chapter describes about the principle of the servo control. Also we introduce programmable servo / sequence controller (PSC) that is effective for servo control.
Vector Engine and Vector Contro
Vector Engine and Vector Control
Vector control technology is one of the essential technologies for driving a motor efficiently with low power consumption. We explain about the vector engine (VE) that can reduce the software load during vector control.
Flash ROM
Flash ROM
Microcontrollers have memories for storing programs, and those for saving data. The memory for programs stores the programs for the microcontroller to operate correctly. The programs should not be rewritten during operation of a microcontroller.
ΔΣ (Delta-sigma) AD Converter
ΔΣ AD Converter
Toshiba's new microcontroller for designing smart meters has integrated high-accurate ΔΣ AD converters to precisely measure the power consumption. This article will explain the basics of AD conversion technique and the mechanism of the ΔΣ AD converter.
Ultrasonic motor control technology: high-resolution control
Ultrasonic motor control technology: high-resolution control
An ultrasonic motor rotates a rotor by using ultrasonic waves with high frequencies more than 20,000Hz which a human cannot hear. This article will briefly explain how ultrasonic motor operates using examples and introduce the way for controlling ultrasonic motors by microcontrollers.
USB (Universal Serial Bus)
USB interface
USB interface is one of the interfaces often found in various devices, such as, USB memories. However, the data transfer mechanism of the USB interface is not well known. This article will provide plain explanation of USB interface, by examining the USB 2.0 overview.
Features of serial interface
Serial interface
A microcontroller has several kinds of serial interfaces. Toshiba produces TX03 microcontroller series which adopt high performance ARM Cortex™-M3 core as the CPUs. The M360 group in TX03 series is the group of microcontrollers which integrate serial interfaces selectively among SIO, UART, SSP (SPI), I2C, USB, CAN, and EtherMAC. The purpose of this article is to introduce each serial interface briefly.
Inverter control
Recently it becomes common technology to use a microcontroller to do Inverter Control as a main controller. Toshiba has produced microcontrollers especially for the Inverter Control usage and expands strategically the lineup of the products to satisfy customers’ strong demand. The purpose of this document is to introduce the Inverter Control technology for non-professional engineers to easily understand the brief knowledge of the technology.
