Holtek's new A/D with LCD microcontroller

This article refers to the address: http://

Holtek will launch the HT46RU66 MCU with LCD Driver specification after the HT46R62, HT46R63, HT46R64 and HT46R65 of the A/D with LCD type MCU, making this series of MCUs more complete and complete, covering larger applications. The range provides users with more flexibility.

The HT46RU66 has 16K OTP program memory and 576 Bytes of general data memory. The built-in LCD Driver provides 46x4 Pixel output capability. Supports 32 I/O pins for designers to apply to input and output control devices, such as external button input control, direct drive LEDs or control of external switch components TRIAC, Relay, etc. The HT46RU66 provides 12-bit resolution A/D input conversion with different sensors for detection, such as voltage, current, temperature, etc. for monitoring external analog signals. Equipped with 8-bit PWM output, the PWM Duty Cycle can be controlled by directly accessing the internal Register, making the use of PWM quite convenient. PWM output can be applied to temperature control, constant voltage, constant current and other controls. In addition, the hardware UART is a full-duplex asynchronous design. The Baud Rate can be set via software and has an automatic error flag display function. When using UART and other systems for data transmission, the software load can be reduced. To make the functions of the microcontroller to the extreme.

The HT46RU66 also provides the following functions: RTC (Real Time Clock), Port A Wake-up Option, 2 sets of 16bit Timer, 1 set of 8bit Timer, PFD (Programmable Frequency Divider) for frequency generation, Buzzer Driver Output function, direct drive pronunciation component , LVR (Low Voltage Reset) and LVD (Low Voltage Detector) functions.

The HT46RU66 is Holtek's latest generation of eight-bit MCUs, which meets industrial specifications. The HT46RU66 is available in 52-pin QFP, 56-pin SSOP and 100-pin QFP packages. It is suitable for all kinds of home appliances, sports equipment and medical equipment that require display functions. Applications such as industrial control.

Holtek also offers a full-featured development system HT-IDE3000 with real-time emulation, memory/buffer access, hardware breakpoint logic settings, execution trace analysis, etc., suitable for faster and more efficient development. Program and debug user use.

This product is currently available for customer sample request and production order. In addition, the HT46RU66 also offers the Mask Edition MCU HT46CU66 with functional features compatibility, which is expected to be launched in October 2006.

An optical fiber cable is a cable containing one or more optical fibers that are used to carry light. The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable will be deployed. Different types of cable are used for different applications, for example long distance telecommunication, or providing a high-speed data connection between different parts of a building.

Optical fiber consists of a core and a cladding layer, selected for total internal reflection due to the difference in the refractive index between the two. In practical fibers, the cladding is usually coated with a layer of acrylate polymer or polyimide. This coating protects the fiber from damage but does not contribute to its optical waveguide properties. Individual coated fibers (or fibers formed into ribbons or bundles) then have a tough resin buffer layer and/or core tube(s) extruded around them to form the cable core. Several layers of protective sheathing, depending on the application, are added to form the cable. Rigid fiber assemblies sometimes put light-absorbing ("dark") glass between the fibers, to prevent light that leaks out of one fiber from entering another. This reduces cross-talk between the fibers, or reduces flare in fiber bundle imaging applications.
