ADUC847BSZ62-5: Application Field and Working Principle

The ADUC847BSZ62-5 is a low cost, low power, 8-bit microcontroller that employs an industry standard RISC instruction set. It is designed for embedded communication and control applications that require a general purpose microcontroller with a low-cost micro-architecture. It is the perfect companion to the popular 8051 family of microcontrollers, offering features such as on-chip clock-multiplication, multiple bus masters and interrupt handling. The device is ideal for applications where speed and low power consumption are of paramount importance.

Features

The ADUC847BSZ62-5 microcontroller combines an impressive array of features with four segment LCD controllers and an integrated oscillator for reduced system cost and increased performance. It has four interrupt levels, up to sixteen interrupt sources and two addressable DMA (Direct Memory Access) ports for fast data transfer. Additionally, the device offers four segment LCD controllers and an integrated oscillator for reduced system cost. Also, it can be set to work in either Interrupt or Polling Mode each with optimal performance.

The ADUC847BSZ62-5 device has 16K bytes of program ROM, 128 bytes of data RAM and four segment LCD controllers. It includes three Interrupt pins, one Reset pin, one Resetbar pin, four User I/O pins, and one I/O CLK pin. It also has three oscillator pins and four additional pins for external peripheral devices. The chip is available in an industry standard, 50-pin pinout.

Applications

The ADUC847BSZ62-5 device is ideally suited for embedded communication and control applications such as remote control, digital home appliances, consumer electronics, and medical equipment.
