2004 lcd module datasheet manufacturer

RC2004A is 20 characters x 4 lines monochrome LCD display module. The RC2004A LCD display has the same specs as RC2004A1. The only difference between them is the position of pins. RC2004A has 16pins on the PCB; pins of RC2004A1 are on the FFC connector. Default interface of RC2004A LCD display is 6800 with built-in IC ST7066; if you require interface such as SPI or I2C, they’re available as well, but the IC will be replaced with RW1063. Power supply of LCD display RC2004A is 5V (3V is optional). Negative voltage version is available for 3V power supply.

Raystar provides various LED backlight combinations for RC2004A display LCD, such as white, yellow-green, amber, red and RGB. You can choose module with LED backlight or without it. There are many LCD modes to choose from, including STN negative, blue ; STN positive, gray/yellow-green ; FSTN positive, white ; FSTN negative, black. RC2004A display LCD 20x4 offers a selection of fonts, for instance, English/Japanese, Europe and Cyrillic (Russian), etc. If you’d like to obtain full datasheet of LCD 20x4, please contact us for more info!

16×2 LCD is named so because; it has 16 Columns and 2 Rows. There are a lot of combinations available like, 8×1, 8×2, 10×2, 16×1, etc. But the most used one is the 16*2 LCD, hence we are using it here.

All the above mentioned LCD display will have 16 Pins and the programming approach is also the same and hence the choice is left to you. Below is the Pinout and Pin Description of 16x2 LCD Module:

These black circles consist of an interface IC and its associated components to help us use this LCD with the MCU. Because our LCD is a 16*2 Dot matrix LCD and so it will have (16*2=32) 32 characters in total and each character will be made of 5*8 Pixel Dots.  A Single character with all its Pixels enabled is shown in the below picture.

So Now, we know that each character has (5*8=40) 40 Pixels and for 32 Characters we will have (32*40) 1280 Pixels. Further, the LCD should also be instructed about the Position of the Pixels.

It will be a hectic task to handle everything with the help of MCU, hence an Interface IC like HD44780 is used, which is mounted on LCD Module itself. The function of this IC is to get the Commands and Data from the MCU and process them to display meaningful information onto our LCD Screen.

The LCD can work in two different modes, namely the 4-bit mode and the 8-bit mode. In 4 bit mode we send the data nibble by nibble, first upper nibble and then lower nibble. For those of you who don’t know what a nibble is: a nibble is a group of four bits, so the lower four bits (D0-D3) of a byte form the lower nibble while the upper four bits (D4-D7) of a byte form the higher nibble. This enables us to send 8 bit data.

As said, the LCD itself consists of an Interface IC. The MCU can either read or write to this interface IC. Most of the times we will be just writing to the IC, since reading will make it more complex and such scenarios are very rare. Information like position of cursor, status completion interrupts etc. can be read if required, but it is out of the scope of this tutorial.

The Interface IC present in most of the LCD is HD44780U,in order to program our LCD we should learn the complete datasheet of the IC. The datasheet is given here.

There are some preset commands instructions in LCD, which we need to send to LCD through some microcontroller. Some important command instructions are given below:
