COP87L88EB/RB Family
8-Bit CMOS OTP Microcontrollers with 16k or 32k
Memory, CAN Interface, 8-Bit A/D, and USART
General Description
The COP87L88EB/RB Family OTP (One Time program-
mable) microcontrollers are highly integrated COP8
TM
Fea-
ture core devices with 16k or 32k memory and advanced
features including a CAN 2.0B (passive) interface, A/D and
USART. These multi-chip CMOS devices are suited for appli-
cations requiring a full featured controller with a CAN inter-
face, low EMI, and versatile communications interfaces, and
as pre-production devices for ROM designs. Pin and soft-
ware compatible 8k ROM versions (COP888EB) are avail-
able as well as a range of COP8 software and hardware de-
velopment tools.
Features include an 8-bit memory mapped architecture, 10
MHz CKI (-XE = crystal oscillator) with 1s instruction cycle,
two multi-function 16-bit timer/counters, WATCHDOG and
clock monitor, idle timer, CAN 2.0B (passive) interface,
MICROWIRE/PLUS

serial I/O, SPI master/slave interface,
fully buffered USART, 8 bit A/D with 8 channels, two power
saving HALT/IDLE modes, MIWU, software selectable I/O
options, low EMI 4.5V to 5.5V operation, program code se-
curity, and 44/68 pin packages.
Note: A companion device with CAN interface, less I/O and
memory, A/D, and PWM timer is the COP87L84BC.
