COP912C 8-Bit Microcontroller
General Description
Note: COP8SA devices are instruction set and pinout compatible supersets of the COP912C devices, and are replacements for these in new designs when possible. The COP912C ROM based microcontrollers are integrated COP8(tm) Base core devices with smaller memory (768 bytes), and fewer on-board features. These single-chip CMOS devices are suited for lower-functionality applications where system cost is of prime consideration. Pin and software compatible (different Vcc range) 4k/32k OTP versions are available (COP87LxxCJ/RJ Family). Erasable windowed versions are available for use with a range of COP8(tm) software and hardware development tools. RAM (bytes) 64 64 Family features include an 8-bit memory mapped architecture, 10MHz CKI with 2.5us(912C) or 2us(912CH) instruction cycle, one multi-function 16-bit timer/counter with PWM, MICROWIRE/PLUS(tm) serial I/O, power saving HALT mode, three clock modes, high current outputs, software selectable I/O options, multi-volt operation and 20 pin packages. Devices included in this datasheet are:
