W78E052DDG Microcontroller: Overview, Features, and Applications

Hi readers welcome to the new post. Here we will discuss W78E052DDG Microcontroller. It is a certain type of controller that has support for the 8052 controller. It is 8-bit controller controller that has 8 KB flash memory unit. It has two 50 six bytes RAM. It also has sixteen-bit timers that has a hardware watchdog. In this tutorial, we will discuss the different factors of this microcontroller in detail. So let’s get started.

Introduction to the W78E052DDG

• W78E052DDG is a microcontroller that supports the different famous 8052 irrespective of the 8051 core.
• It is an 8-bit MIcrocotnroller unit that comes with an 8 KB flash. It comes with 256bytes of RAM, and 4 8-bit bi-directional input-output ports, denoted as P0, P1, P2, P3, and 4-bit I/O port P4.
• It also has 3 16-bit timers, hardware watchdog timers, and a serial port that helps
• Three 16-bit timers/counters, a hardware watchdog timer, and a serial port are used for easy integration with different projects.
• This controller has optional 12T or 6T mode features and uses 12 clocks per machine cycle where the speed of the processor is about 40 MHz at 5V operating voltage.
• If there is a 6T mode working, 6 clock per machine cycle operation helps the controller speed to about  20 MHz for 5V operating voltage.
• It is compatible with 2.4 to 5.5V and is best to use for  3.3V to 5V logic-level operations.

Introduction to microcontroller programming?

• Some features exist for the conversion of the normal digital watch into a programmable watch. In place of a CPU, the watch uses 16 bit LCD, 64 bytes of programmable RAM, and 8 bytes of flash memory

• Programmable RAM is easy to access from the controller and seen with data through 2 RS232 serials ports. One port is connected to computers and the other to the watch.
• For the programmable phase, the controller and display are connected through 8-bit serial interfaces with each other and 8-bit controller serial to 8-bit computer interface.
• The 8-bit UART controller interfacing is used for the serial programming of the watch, or the controller 8-bit input/output port is used for programming the watch through reading 8-bit I/O data from the watch.

Features of the W78E052DDG Microcontroller

• Here are some features listed
• Its core is  8051-based CMOS and comes with  8052 compatible instruction sets
• Its data bus width is 8 bit and its maximum clock frequency is  40 MHz (12T mode, 12 clocks for machine cycle operation), 20 MHz.
• It has a program memory size of  8kB with a data RAM of  256B
• Its operating voltage is 2.4V to 5.5 V
• Minimum operating Temperature is – 40C and  Maximum Operating Temperature is + 85C
• Its program memory is flash and its interface is UART.
• it has 8-bit input-output ports of 4  and timers are 3

Programming Microcontroller W78E052DDG

Nuvoton 8052-based microcontrollers get programmed with the use of different software that is easily available. This controller has support for MCS-51. For programming the nuvoton microcontroller, use IDE. The compiler is a component where the program is transformed into an MCU readable shape that is known as a HEX file. The commonly used IDE is   Keil u-vision and the Compiler is C51 Compiler.
