COP888FH
8-Bit CMOS ROM Based Microcontrollers with 12k
Memory, Comparators, USART and Hardware
Multiply/Divide
General Description
The COP888FH Family of ROM based microcontrollers are
highly integrated COP8™ Feature core devices with 12k
memory and advanced features including Analog compara-
tors, and Hardware Multiply/Divide. These single-chip
CMOS devices are suited for more complex applications re-
quiring a full featured controller, low EMI, two comparators, a
full-duplex USART, and hardware multiply/divide functions.
COP87L88FH devices are pin and software compatible (dif-
ferent VCC range) 16k OTP (One Time Programmable) ver-
sions 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, hardware
multiply/divide functions, three multi-function 16-bit timer/
counters with PWM, full duplex USART, MICROWIRE/
PLUS™, two Analog comparators, two power saving HALT/
IDLE modes, MIWU, idle timer, high current outputs,
software selectable options WATCHDOG™ and clock/
oscillator mode, low EMI 2.5V to 5.5V operation, and 28/
40/44 pin packages.

Note 15: Maximum rate of voltage change must be less than 0.5V/ms.
Note 16: Supply current is measured after running 2000 cycles with a square wave CKI input, CKO open, inputs at rails and outputs open.
Note 17: 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 or
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 comparators 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 crys-
tal clock mode.
Note 18: Pins G6 and RESET are designed with a high voltage input network. 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 resistance to VCC is 750Ω
(typical). These two pins will not latch up. The voltage at the pins must be limited to less than 14V. WARNING: Voltages in excess of 14V will cause damage to the
pins. This warning excludes ESD transients.
Note 19: Parameter characterized but not tested.
Note 20: tc = Instruction cycle time.
