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 2: tc = Instruction Cycle Time
Note 3: Maximum rate of voltage change must be < 0.5 V/ms.
Note 4: Supply and IDLE currents are measured with CKI driven with a square wave Oscillator, CKO driven 180˚ out of phase with CKI, inputs connected to VCC
and outputs driven low but not connected to a load.
Note 5: The HALT mode will stop CKI from oscillating in the RC and the Crystal configurations. Measurement of IDD HALT is done with device neither sourcing nor
sinking current; with L, C, and G0–G5 programmed as low outputs and not driving a load; all outputs programmed low and not driving a load; all inputs tied to VCC;
clock monitor and comparator disabled. Parameter refers to HALT mode entered via setting bit 7 of the G Port data register. Part will pull up CKI during HALT in crystal
clock mode.
Note 6: Pins G6 and RESET are designed with a high voltage input network. These pins allow input voltages > VCC and the pins will have sink current to VCC when
biased at voltages > VCC(the pins do not have source current when biased at a voltage below VCC). The effective resistance to VCC is 750Ω (typical). These two
pins will not latch up. The voltage at the pins must be limited to < 14V. WARNING: Voltages in excess of 14V will cause damage to the pins. This warning ex-
cludes ESD transients.
Note 7: The output propagation delay is referenced to the end of the instruction cycle where the output change occurs.
Note 8: Parameter characterized but not tested.
