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 COP8Feature 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 WATCHDOGand clock/
oscillator mode, low EMI 2.5V to 5.5V operation, and 28/
40/44 pin packages.

Note 2: Rate of voltage change must be less than 0.5V/ms.
Note 3: Supply current is measured after running 2000 cycles with a square wave CKI input, CKO open, inputs at rails and outputs open.
Note 4: The HALT mode will stop CKI from oscillating in the RC and the Crystal configurations. Test conditions: All inputs tied to VCC, L and G ports in the TRI-STATE
mode and tied to ground, all outputs low and tied to ground. The clock monitor and the comparator are disabled.
Note 5: 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 750(typical). These two pins will not latch up. The voltage at the pins must be limited to less than 14V.
Note 6: The output propagation delay is referenced to the end of the instruction cycle where the output change occurs.
