1 / 43 page  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 appli- cations requiring a full featured, low EMI controller with an A/D (only one external capacitor required). COP8ACC7 de- vices are pin and software compatible (different V CC range) 16k OTP EPROM versions for pre-production. Erasable win- dowed versions are available for use with a range of COP8 software and hardware development tools. Family features include an 8-bit memory mapped architec- ture, 4 MHz CKI with 2.5µs instruction cycle, 6 channel A/D with 12-bit resolution, analog capture timer, analog current source and V CC/2 reference, one multi-function 16-bit timer/ counter, MICROWIRE/PLUS serial I/O, two power saving HALT/IDLE modes, MIWU, high current outputs, software selectable I/O options, WATCHDOG™ timer and Clock Moni- tor, Low EMI 2.5V to 5.5V operation and 20/28 pin packages.
