COP8ACC Family 8-Bit CMOS ROM Based and OTP Microcontrollers with 4k or 16k Memory and High Resolution A/D
General Description
The COP8ACC Family ROM based microcontrollers are highly integrated COP8™ Feature core devices with 4k memory and advanced features including a High-Resolution A/D. These single-chip CMOS devices are suited for applications requiring a full featured, low EMI controller with an A/D (only one external capacitor required). COP8ACC7 devices are pin and software compatible (different VCC range) 16k OTP EPROM versions for pre-production. Erasable windowed versions are available for use with a range of COP8 software and hardware development tools.

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 6: The output propagation delay is referenced to the end of the instruction cycle where the output change occurs. Note 7: Parameter characterized but not tested. Note 8: tC = Instruction Cycle Time.
