20x4 lcd display datasheet in stock
Adding to what N1VG posted, you can indeed control this module, or any other HD47780-based character LCD module for that matter, with six lines. If you"re using an Arduino as the brains for your project, the LiquidCrystal library that comes with the Arduino IDE will run a HD47780-based module from six pins without having to manage things like passing nybbles to the module - you can just include LiquidCrystal.h, declare a new object (e.g., LiquidCrystal lcd(2,3,4,5,6,7); to use pins 2-7 to control the module), and just shoot data to it with the print() and write() commands. The library will handle the rest.
You can get by with 6 I/O lines for an HD44780. Just keep the RW pin pulled low (assuming you don"t need to read from the display) and connect only the high 4 data lines. You"ll need to send it a command to put the bus into 4-bit mode, and of course you"ll have to write to it one nybble at a time, but that"s not hard to do.
Not sure if this is normal. My LCD, using the liquidcrystal library, wraps to the third line after finishing the first (then it goes to the second, then the fourth), but addressing each line is normal when using setCursor().
The "solution" I came up with was simply to use the cursor positioning feature to write to the lines I wanted. Since you"re writing strings anyway, it"s not terribly difficult to do. If you"re making a display for a project, just account for what ends up on what line.
Does anyone know where I can get a pre-manufactured ribbon cable assembly suitable for use with this LCD? Soldering a thru-hole connector or pin header to the panel is something that can probably be done in our shop, but assembling our own cables from scratch may be a bit beyond our ability to do routinely... We just need a 6" cable with (say) female sockets (16x1) at both ends... The other end to plug into a suitable header on an Arduino-based PCB... Thanks for any tips, -Mike
I made a tutorial (in portuguese) about how to use, create custom characters and design menus for the LCD display. Take a look: http://engenheirando.com/arduino/displaylcd/
Can anyone confirm if this works with an Arduino Uno? Following these directions (http://arduino.cc/en/Tutorial/LiquidCrystal), no matter what I do I can only see solid blocks on two of the 4 rows when the pot is turned all the way down. Is this because the Arduino library is for a 16x2 character LCD and this one is a 20x4?
I forgot to buy breakaway male header pins for this LCD module. However, I do have spare female headers from a previous project. Would I be able to use the female headers?
This display has a parallel interface, so it will require about 6 I/O pins to run. The parallel protocol is complex, but there are good LCD libraries out there which make it easy to use. The difference between this and a serial display is that the serial display will only require one I/O pin.
If you use straight headers, the clips used to anchor the lcd to the board get in the way when you try to plug it into a breadboard with power rails on the side.
A very useful LCD - and, if you need it to take even less than 6 pins, there"s a library (by Chris Parish) for using it with a 74HC595 shift register that reduces it to 3 digital output pins. The library and Chris"s tutorial is here - http :// cjparish.blogspot.com/2010/01/controlling-lcd-display-with-shift.html
@Twiddler: Yes, it"s possible to write too fast. Check the write cycle timings in the datasheet. The enable signal can"t be cycled faster than 2MHz. Also after each command sent to the LCD, you have to wait until the busy flag is clear, or delay several microseconds to milliseconds (depending on which command).
The Displaytech 204G series is a lineup of 20x4 character LCD modules. These modules have a 98x60 mm outer dimension with 77x25.2 mm viewing area on the display. The 204G 20x4 LCD displays are available in STN or FSTN LCD modes with or without an LED backlight. The backlight color options include yellow green, white, blue, pure green, or amber color.

A wide variety of 20x4 lcd display datasheet options are available to you, You can also choose from original manufacturer, odm 20x4 lcd display datasheet,As well as from cob, character 20x4 lcd display datasheet.
STN, Yellow/Green background, Yellow/Green LED, bottom (or 6:00) viewing angle, Transflective (positive), RoHS Compliant. Available in both 3V or 5V power supply options.This display has a wide temperature range: -20° Celcius to +70° Celcius which equates to (-4° Fahrenheit to +158° Fahrenheit).
STN (Super-twisted Nematic) provides a sharper image and wider viewing angle than TN (Twisted Nematic). The cost for STN if approximately 5% higher than TN. STN is an ideal fluid for outdoor products that need to be read at various angles. The Transflective polarizer is a mixture of Reflective and Transmissive. It provides the ability to read the LCD with or without the backlight on. It will work for all lighting conditions from dark with backlight to direct sunlight which makes it the most common choice. There is no cost difference between Transflective, Transmissive and Reflective.

Starting August 1, 2015 the "Drive Bay Kit Configurator" located at https://www.crystalfontz.com/products/select_kit.html will no longer be functional for ordering one of our Serial or USB displays (CFA533, CFA631, CFA632, CFA633, CFA634, CFA635, and CFA735) in a bracket or SLED. This functionality is being moved to the Customize and Add to Cart process when checking out. This will allow for further customization by our customers to better fit their needs.
The new part numbers will have the bracket / SLED and overlay type as a PREFIX to the configured part number. The choice for bracket / SLED to a display order will be via the cart options. Our CFA835 displays were introduced with these configuration options.
As part of our continuous improvement process, we are integrating the ordering of displays in drive bay and SLED kits as part of the display ordering process.
The CFA635 family of modules is being reactivated with a new LCD controller chip, the Rockworks RW1067. The majority of the changes to the firmware have been in support of the RW1067 LCD controller and are transparent to the user interface. The changes to the CFA635 2v0 firmware:
Any command sent specifically to the Samsung S6A0073 will need to be reviewed / modified for the commands / registers of the Rockworks RW1067. Please contact the Crystalfontz Engineering Support Team at support@crystalfontz.com for the RW1067 datasheet.
When the CFA635 family was scheduled for End of Life (see PCN #10365) there was no replacement available for the Samsung S6A0073 LCD controller. The CFA735 family was designed as replacement for the CFA635, allowing a path for improved performance, graphics, and the ability for end users to write their own firmware to take advantage of the capabilities of the enhanced hardware.
After the development of the CFA735 family, the RW1067 was developed as a replacement for the Samsung S6A0073 LCD controller for Crystalfontz America, Inc by Rockworks (China).

The CFA635 is a character based intelligent LCD module built around a Cypress PSoC® micro-controller and a Samsung S6A0073 LCD controller. Samsung announced the EOL of the S6A0073 at the end of 2007. After the announcement, Crystalfontz America, Inc began designing a replacement module and planned for continuing to manufacture and support the CFA635 family until a compatible replacement module was designed and available.
