Quick Reference

The ST7282A5/B5 is a 32K ROM version of the ST72 family, using the ST72CORE and N-Wel

technology. It is derived from EPROM M4 version replacing EPROM by ROM.

Two different commercial products are supported by this device : ST7282A5 (no LCD driver) func

tionnality described in specification SD70KL1618 ed. F) and ST7282B5 (LCD driver) functionnality

described in specification 96096 ed. B). It contains an LCD controller/driver with 20 segment and 16 backplane outputs able to drive up to 20 x 16 = 320 segments.

The LCD control logic reads automatically data from the LCD-RAM independently from the ST7282 B5.
