ST7586S
Display Data RAM (DDRAM)
ST7586S containing a 384x160x2 bit static RAM stores the display data. The display data RAM (DDRAM) stores the pixel
data of the LCD. The built-in DDRAM is an addressable memory array with 384 columns by 160 rows. ST7586S provides two
kinds of display modes (monochrome mode and 4-level gray scale mode) and a fast-addressing mode for fast updating
display data. Each column address represents 3 sub-columns. For example, setting the column address to “01h” means that
upcoming 8 bits data is addressing to column 3; column 4 and column 5 respectively (refer to Fig. 3 and Fig. 4). The display
data which is written by MCU will be stored in DDRAM with the format of D7 at the left and D0 at the right when MX=0 (refer
to 錯誤
reads the pixel data in DDRAM, and then it outputs to COM/SEG pad. While the LCD controller operates independently,
display data can be written into DDRAM at the same time and data is also being displayed on LCD panel without causing the
abnormal display.
