COP888CF
8-Bit CMOS ROM Based Microcontrollers with 4k
Memory and A/D Converter
General Description
The COP888CF ROM based microcontrollers are highly in-
tegrated COP8™ Feature core devices with 4k memory and
advanced features including an A/D Converter. These single-
chip CMOS devices are suited for applications requiring a
full featured controller with an 8-bit A/D converter. Pin and
software compatible (different VCC range) 16k/32k OTP
(One Time Programmable) versions are available
(COP87L88CF Family) 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 1 µs instruction cycle, two multi-
function 16-bit timer/counters, MICROWIRE/PLUS™ serial
I/O, one 8-bit/8-channel A/D converter with prescaler and
both differential and single ended modes, crystal or R/C os-
cillator, two power saving HALT/IDLE modes, idle timer,
MIWU, high current outputs, software selectable I/O options,
WATCHDOG™ timer and Clock Monitor, 2.5V to 6.0V opera-
tion and 28/40/44 pin packages.

A/D Converter Specifications (Continued)
Note 17: Pins G6 and RESET are designed with a high voltage input network for factory testing. These pins allow input voltages greater than VCC and the pins will
have sink current to VCC when biased at voltages greater than VCC (the pins do not have source current when biased at a voltage below VCC). The effective resis-
tance to VCC is 750Ω (typical). These two pins will not latch up. The voltage at the pins must be limited to less than 14V.
Note 18: For VIN(−)≥VIN(+) the digital output code will be 0000 0000. Two on-chip diodes are tied to each analog input. The diodes will forward conduct for analog
input voltages below ground or above the VCC supply. Be careful, during testing at low VCC levels (4.5V), as high level analog inputs (5V) can cause this input diode
to conduct — especially at elevated temperatures, and cause errors for analog inputs near full-scale. The spec allows 50 mV forward bias of either diode. This means
that as long as the analog VIN does not exceed the supply voltage by more than 50 mV, the output code will be correct. To achieve an absolute 0 VDC to 5 VDC input
voltage range will therefore require a minimum supply voltage of 4.950 VDC over temperature variations, initial tolerance and loading. The voltage on any analog input
should be −0.3V to VCC +0.3V.
