Embedded – Microcontrollers

The DS80C320-MCG is a 8-bit microcontroller from Maxim Integrated. It is based on the industry-standard 8051 architecture, and combines on-chip Flash memory, analog-to-digital conversion and serial peripheral interface. The microcontroller is suited for industrial and consumer applications such as printer control and medical devices.

The 8051 core was initially developed by Intel in 1980 and has since become the basis for a wide range of 8-bit controllers. The 8051 is an 8-bit microcontroller architecture that features a powerful instruction set, along with accurate timing and interrupt control. It is well-suited for embedded applications such as motor speed control, data acquisition, process control and communications.

The DS80C320-MCG contains 1KBytes of on-chip Flash memory and 64KBytes of external code-ROM. The Flash memory is used to store the application program code and data, while the on-chip RAM is used for variables and stack. The 16-bit timer is used for timing and pulse generation. The on-chip analog-to-digital converter is used for product characterization and front-end signal conditioning. The serial peripheral interface provides for synchronous output and input of serial data up to 1Mbps.

The DS80C320-MCG microcontroller is targeted at industrial and consumer markets with applications such as printer control, stepper motor control, medical devices, gaming, digital audio, data acquisition and communications. The device is also cost-effective and easy to use, which makes it suitable for a wide range of embedded applications.

The DS80C320-MCG uses a single instruction cycle architecture to execute instructions in a single clock cycle. The 8085-compatible 8051 instruction set provides instruction-level compatibility with other 8051-compatible microcontrollers. This allows the instruction set and code to be ported to the DS80C320-MCG. The external memory is connected through a 20-pin GPIO port, allowing for connection of external memory, such as RAM, ROM, EEPROM and Flash.

The microcontroller also includes a quadrature decoder for quadrature rotation. The decoder can generate pulse outputs in both clockwise and counterclockwise directions. The on-chip analog-to-digital converter allows for 12-bit resolution and conversion speed of 11MHz. It is also capable of single-ended or differential inputs and software calibration. The encoder operates in 8-bit resolution and can generate an interrupt upon detection of changes in the encoder values.

The DS80C320-MCG uses a 7-level 15-instruction interrupt controller. The processor can be put into a low power sleep mode and interrupt on external events. It also supports two on-chip 16-bit timers, which allow for precision timing and event control. The serial peripheral interface is capable of asynchronous and synchronous serial data transmission and reception. The IRQ pins should be used to notify the processor of external events.

The DS80C320-MCG is a powerful 8-bit microcontroller with a wide range of features and on-chip peripherals. The 8051 architecture is well-suited for embedded applications and the device enables engineers to develop embedded applications quickly and cost-effectively. The DS80C320-MCG is a reliable and low-cost solution for products needing an 8-bit microcontroller with high performance, fast data transfer and a wide range of features.
