COP87L88GGV-XE
8-Bit One-Time Programmable OTP Microcontroller with UART and Three Multi-Function Timers
COP87L84BC
8-Bit CMOS OTP Microcontrollers with 16k Memory,
Comparators, and CAN Interface
General DescriptionThe COP87L84BC OTP (One Time Programmable) micro-
controllersare highly integrated COP8™ Feature corede-
viceswith16k OTPEPROMmemoryand advanced features
includinga CAN 2.0B (passive) interface andtwo Analog
comparators. These multi-chip CMOS devicesare suitedfor
applications requiringafull featured controllerwitha CANin-
terface,and 8-bit39kHz PWM timer,andas pre-production
devicesfora masked ROM design.Pinand software com-
patible2k ROM versionsare available (COP884BC) witha
rangeof COP8 softwareand hardware development tools.
Features includean 8-bit memory mapped architecture,10
MHzCKI (-XE= crystal oscillator) with1μs instruction cycle,
one multi-function 16-bit timer/counter, 8-bit39 kHz PWM
timer with2 outputs, CAN 2.0B (passive) interface,
MICROWIRE/PLUS™ serial I/O,two Analog comparators,
two power saving HALT/IDLE modes,idle timer, MIWU, soft-
ware selectable I/Ooptions,low EMI4.5Vto 5.5V operation,
and28pin packages.
Note:The companion devices with CAN interface, moreI/O
and memory, A/D,and USARTarethe COP87L88EB/RB.
