COP888EK
8-Bit CMOS ROM Based Microcontrollers with 8k
Memory, Comparator, and Single-slope A/D Capability
General Description
The COP888EK ROM based microcontrollers are highly in-
tegrated COP8Feature core devices with 8k memory and
advanced features including a Multi-Input Comparator and
Single-slope A/D capability. These single-chip CMOS de-
vices are suited for applications requiring a full featured, low
EMI controller with an analog comparator, current source,
and voltage reference. The COP87L88EK/RK Family de-
vices are pin and software compatible (different V
CC range)
16k or 32k OTP (One Time Programmable) versions for pre-
production, and for use with a range of COP8 software and
hardware development tools.
Family features include an 8-bit memory mapped architec-
ture, 10 MHz CKI with 1µs instruction cycle, three multi-
function 16-bit timer/counters with PWM, MICROWIRE/
PLUSserial I/O, one analog comparator with seven input
multiplexor, an analog current source and V
CC reference,
two power saving HALT/IDLE modes, idle timer, MIWU, high
current outputs, software selectable I/O options, WATCH-
DOGtimer and Clock Monitor, Low EMI 2.5V to 6.0V op-
eration and 28/40/44 pin packages.
