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
complete microcomputers containing all system timing in-
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 ms instruc-
tion cycle rate provides optimal throughput
The COP8780C COP8781C and COP8782C can be config-
ured to EMULATE the COP880C COP840C and COP820C
