4-81T SINGLE CHIP MICROCOMPUTER
DESCRIPTION
The fJP0553 is a fJCOM-43 4-bit single chip microcomputer with high voltage outputs
that can be pulled to -35V for direct interfacing to vacuum fluorescent displays. The
fJP0553 is manufactured with a standard PMOS process, allowing use of a single -1 OV
power supply. The fJP0553 provides all of the hardware features of the fJCOM-43
family, and executes all 80 instructions of the fJCOM-43 instruction set.
