COP884BC/COP885BC
8-Bit CMOS ROM Based Microcontrollers with 2k
Memory, Comparators, and CAN Interface
General Description
The COP884BC ROM based microcontrollers are highly in-
tegrated COP8Feature core devices with 2k memory and
advanced features including a CAN 2.0B (passive) interface
and two Analog comparators. These single-chip CMOS de-
vices are suited for applications requiring a full featured con-
troller with a CAN interface, low EMI, and an 8-bit 39 kHz
PWM timer. COP87L84BC devices are pin and software
compatible 16k OTP (One Time Programmable) versions for
pre-production, and for use with a range of COP8 software
and hardware development tools.
Features include an 8-bit memory mapped architecture, 10
MHz CKI (crystal osc) with 1µs instruction cycle, one multi-
function 16-bit timer/counter, 8-bit 39 kHz PWM timer with 2
outputs, CAN 2.0B (passive) interface, MICROWIRE/
PLUSserial I/O, two Analog comparators, two power sav-
ing HALT/IDLE modes, idle timer, MIWU, software selectable
I/O options, Power on Reset, low EMI 4.5V to 5.5V opera-
tion, and 20/28 pin packages.
Note: A companion device with CAN interface, more I/O and
memory, A/D, and USART is the COP888EB.
