The National Semiconductor COP8 is an 8-bit CISC core microcontroller. COP8 is an enhancement to the earlier COP400 4-bit microcontroller family. COP8 main features are: Large amount of I/O pins Up to 32 KB of Flash memory/ROM for code and data Very low EMI Many integrated peripherals (meant as single chip design) In-System Programming Free assembler toolchain. Commercial C compilers available Free Multitasking OS and TCP/IP stack Peak of 2 million instructions per second
The COP8 has a basic instruction cycle time 1/10 of the clock frequency; a maximum 10 MHz clock will result in a maximum 1 MHz instruction execution rate. (The 10 MHz clock is used directly by some timer peripherals.) The maximum instruction execution rate is 1 cycle per byte, and most 1-byte instructions operate in one instruction cycle. Some, particularly branch instructions, take one or two cycles more. Some models include a clock doubler, and although they still accept a maximum 10 MHz input clock, they internally double it to a 20 MHz master clock which then results in a 2 MHz instruction execution rate.
