  • basic ebook circuit implemented with a microcontroller AT89C51, a 32Kx8 bit Low Power CMOS Static RAM 62256 and a 74LS373 composed by 8 D-type flip-flops for driving highly-capacitive or low-impedance loads. these registers have the capability of being connected directly to and driving the bus lines without need for interface or pull-up components.the C code, compiled by the keil uvision compiler, write in the RAM 10 screens, 320 characters and show them on the display according to the button pushed.
