lcd module 20x4 datasheet free sample

The CFA635 family of modules is being reactivated with a new LCD controller chip, the Rockworks RW1067. The changes to the CFA635 1v2 hardware are as follows:

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).

This announcement impacts all variants, interfaces, and part numbers that currently use the CFA635 family of modules. The CFA635 can continue to be used in current and future designs.

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.

Detailed in formation on migrating from the CFA635 family to the CFA735 family of intelligent modules. The document covers the similarities and differences between the two family of modules.

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.

As part of our continuous improvement process, the engineering services group at Crystalfontz America Inc. is announcing the End of Life (EOL) to our CFA635 family of modules. This end of life is scheduled to take place at the end of 2012 Q2.

The CFA635 is being replaced with the first of a new generation of intelligent modules from Crystalfontz America, Inc. This new module is the CFA735 family. The CFA735 family has been primarily designed to be a replacement for the CFA635 family with a number of enhancements / improvements.

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.

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().

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).
