Product data sheet Rev. 3 — 3 December 2014 9 of 54 NXP Semiconductors PCA8576F Automotive 40 × 4 LCD driver 7.3 Display RAM The display RAM is a static 40 4-bit RAM which stores LCD data. There is a one-to-one correspondence between • the bits in the RAM bitmap and the LCD segments/elements • the RAM columns and the segment outputs • the RAM rows and the backplane outputs. A logic 1 in the RAM bitmap indicates the on-state of the corresponding LCD element; similarly, a logic 0 indicates the off-state. The display RAM bit map, Figure 4, shows the rows 0 to 3 which correspond with the backplane outputs BP0 to BP3, and the columns 0 to 39 which correspond with the segment outputs S0 to S39. In multiplexed LCD applications the segment data of the first, second, third and fourth row of the display RAM are time-multiplexed with BP0, BP1, BP2, and BP3 respectively. The display RAM bitmap shows the direct relationship between the display RAM column and the segment outputs; and between the bits in a RAM row and the backplane outputs. Fig 4. Display RAM bit map |
