COP410L/COP411L/COP310L/COP311L
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.
