... FD2000 1. OVERVIEW The FD2000 is 1/8 to 1/10 duty dot matrix LCD display controller/drivers that supports the display of characters, numbers, and symbols. In addition to generating dot matrix LCD drive signals based on data transferred serially from a microcontroller, the FD2000 also provide on-chip character display ROM and RAM to allow display systems to be implemented easily ...

... FD2000 6. BLOCK FUNCTIONS 6.1. AC (ADDRESS COUNTER counter that provides the addresses used for DCRAM and ADRAM. The address is automatically modified internally, and the LCD display state is retained. 6.2. DCRAM (DATA CONTROL RAM) DCRAM is RAM that is used to store display data expressed as 8-bit character codes. (These character codes are converted dot matrix character patterns using CGROM or CGRAM ...

... FD2000 6.3. ADRAM (ADDITIONAL DATA RAM) ADRAM is RAM used to store the ADATA display data. ADRAM has a capacity bits, and the stored display data is displayed directly without the use of CGROM or CGRAM. The table below lists the correspondence between the 4-bit ADRAM address loaded into AC and the display position on the LCD panel. ...

... FD2000 6.4. CGROM (CHARACTER GENERATOR ROM) CGROM is ROM used to generate the 240 kinds dot matrix character patterns from the 8- bit character codes. CGROM has a capacity of 240 x 45 bits. When a character code is written to DCRAM, the character pattern stored in CGROM corresponding to the character code is displayed at the position on the LCD corresponding to the DCRAM address loaded into AC ...

... FD2000 7. RESET FUNCTION The FD2000 is reset when a low level is applied to the RESETB pin at power on and, in normal mode reset the FD2000 create a display with all LCD panels turned off. However, after a reset applications must set the contents of DCRAM, ADRAM, and CGRAM before turning on display with a “display on/off control” instruction since the contents of these memories are undefined. That is, applications must execute the following instructions. − ...
