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 VCC 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 VCC 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.

Note 25: While performance characteristics are given at VCC = 5.0V, the analog function block will operate over the entire 2.5V–6.0V VCC range. Accuracy of the
VCC/2 reference and the constant current source is not guaranteed beyond the specified limits.
Note 26: The device is capable of operating over a common mode voltage range of 0 to VCC − 1.5V, however increased offset voltage will be observed between 0V
and 0.4V.
