COP888EB
8-Bit CMOS ROM Based Microcontrollers with 8k
Memory, CAN Interface, 8-Bit A/D, and USART
General Description
The COP888EB ROM based microcontrollers are highly in-
tegrated COP8Feature core devices with 8k memory and
advanced features including a CAN 2.0B (passive) interface,
A/D and USART. These single-chip CMOS devices are
suited for applications requiring a full featured controller with
a CAN interface, low EMI, and versatile communications in-
terfaces. COP87L8EB/RB devices are pin and software
compatible 16k or 32k OTP (One Time Programmable) ver-
sions 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 with 1µs instruction cycle, two multi-function 16-bit
timer/counters, WATCHDOGand Clock Monitor, CAN
2.0B (passive) interface, MICROWIRE/PLUSserial I/O,
SPI master/slave interface, fully buffered USART, 8-bit A/D
with 8 channels, two power saving HALT/IDLE modes,
MIWU, idle timer, software selectable I/O options, low EMI
4.5V to 5.5V operation, and 44/68 pin packages.
Note: A companion device with CAN interface, less I/O and
memory, and PWM timer is the COP888BC.
