COP8780C/COP8781C/COP8782C
8-Bit One-Time Programmable (OTP) Microcontroller
General Description
The COP8780C, COP8781C and COP8782C are members
of the COPS
TM
8-bit microcontroller family. They are fully
static microcontrollers, fabricated using double-metal, dou-
ble poly silicon gate microCMOS EPROM technology.
These devices are available as UV erasable or One Time
Programmable (OTP). These low cost microcontrollers are
terrupt logic, EPROM, RAM, and I/O necessary to imple-
ment dedicated control functions in a variety of applications.
Features include an 8-bit memory mapped architecture, MI-
CROWIRE/PLUS
TM
serial I/O, a 16-bit timer/counter with
associated 16-bit autoreload/capture register, and a multi-
sourced interrupt. Each I/O pin has software selectable op-
tions to adapt the device to the specific application. These
devices operate over a voltage range of 4.5V to 6.0V. An
efficient, regular instruction set operating at a 1
m
s instruc-
tion cycle rate provides optimal throughput.
The COP8780C, COP8781C and COP8782C can be config-
ured to EMULATE the COP880C, COP840C and COP820C
microcontrollers.
