Single-Chip N-Channel Microcontrollers
General Description
The COP410L and COP411L Single-Chip N-Channel Micro-
controllers are members of the COPS^TM family fabricated
using N-channel silicon gate MOS technology These Con-
troller Oriented Processors are complete microcomputers
containing all system timing internal logic ROM RAM and
I O necessary to implement dedicated control functions in a
variety of applications Features include single supply oper-
ation a variety of output configuration options with an in-
struction set internal architecture and I O scheme de-
signed to facilitate keyboard input display output and BCD
data manipulation The COP411L is identical to the
COP410L but with 16 I O lines instead of 19 They are an
appropriate choice for use in numerous human interface
control environments Standard test procedures and reliable
high-density fabrication techniques provide the medium to
large volume customers with a customized Controller Ori-
ented Processor at a low end-product cost
The COP310L and COP311L are exact functional equiva-
lents but extended temperature versions of COP410L and
COP411L respectively
The COP401L should be used for exact emulation
