8-Bit One-Time Programmable (OTP) Microcontroller
General Description
The COP8780C, COP8781Cand COP8782Care membersthe COPSTM 8-bit microcontroller family. Theyare fully
static microcontrollers, fabricated using double-metal, dou-
ble poly silicon gate microCMOS EPROM technology.
These devicesare availableasUV erasableor One Time
Programmable (OTP). Theselow cost microcontrollersare
complete microcomputers containingall system timing,in-
terrupt logic, EPROM, RAM,andI/O necessaryto imple-
ment dedicated controlfunctionsin avarietyof applications.
Features includean 8-bit memory mapped architecture,MI-
CROWIRE/PLUSTM serial I/O,a 16-bit timer/counter with
associated 16-bit autoreload/capture register,anda multi-
sourced interrupt. EachI/Opinhas software selectableop-
tionsto adaptthe devicetothe specific application. These
devices operate overa voltage rangeof 4.5Vto 6.0V.An
efficient, regular instructionset operatingata1ms instruc-
tion cyclerate provides optimal throughput.
The COP8780C, COP8781Cand COP8782Ccanbe config-
uredto EMULATEthe COP880C, COP840Cand COP820C
microcontrollers.
