COP880C Microcontrollers
General Description
The following part numbers are pin count and temperature variations of the COP880C: COP680C/COP681C/ COP682C/COP881C /COP882C/COP980C/ COP981C/COP982C. The COP880C devices are members of the COP8 microcontroller family. They are fully static parts, fabricated using double-metal silicon gate microCMOS technology. This low cost microcontroller is a complete microcomputer containing all system timing, interrupt logic, ROM, RAM, and I/O necessary to implement dedicated control functions in a variety of applications. Features include an 8-bit memory mapped architecture, MICROWIRE/PLUSTM serial I/O, a 16-bit timer/ counter with capture register and a multi-sourced interrupt. Each I/O pin has software selectable options to adapt the device to the specific application. The part operates over a voltage range of 2.5 to 6.0V. High throughput is achieved with an efficient, regular instruction set operating at a 1 microsecond per instruction rate. n n n n High current outputs (8 pins) Schmitt trigger inputs on Port G MICROWIRE PLUS serial I/O Packages: -- 20 DIP/SO with 16 I/O pins -- 28 DIP/SO with 24 I/O pins -- 40 DIP, 36 I/O pins -- 44 PLCC, 36 I/O pins

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, C and G ports TRI-STATE and tied to ground, all outputs low and tied to ground. 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 resistance to VCC is 750 (typ). These two pins will not latch up. The voltage at the pins must be limited to less than 14V. Note 6: To maintain RAM integrity, the voltage must not be dropped or raised instantaneously.
