Rom From Eprom

The ST7282A5 - ST7282B5 is a 32K ROM version of the ST72 family, using the ST72CORE and N-Well 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 seg- ment 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. Further it contains up to 62 I/O pins, 24 of them CAN be used as Analog inputs to the 8 bit analog- digital converter. Each digital I/O pin CAN individu- ally be defined by software to work in one of the following modes: open-drain output, push pull out- put, input, input with pull-up (23 pins only) or inter- rupt input with pull up (23 pins only). 3 of the digital I/O pins serve as Interface to the SIO. On pin PA4 the pull-up resistor is desactivated. By STMicroelectronics
