1 / 46 page 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 COP8™ Feature 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/ PLUS™ serial 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- DOG™ timer and Clock Monitor, Low EMI 2.5V to 6.0V op- eration and 28/40/44 pin packages.
