4-81T SINGLE CHIP MICROCOMPUTER
NEe
,.,. PD554L
DESCRIPTION
The j.lPD554L is a j.lCOM-45 4-bit single chip microcomputer with high voltage out-
puts. and low power consumption_ The outputs can be pulled to -35V for direct
interfacing to vacuum fluorescent displays. The j.lPD554L is manufactured with a low-
power-consumption PMOS process, allowing use of a -8V, low current power supply.
The j.lPD554 L provides all of the hardware features of the j.lCOM-45 family, and
executes all 58 instructions of the j.lCOM-45 instruction set.
