Zilog’s eZ8^TM CPU, latest 8-bit CPU meets the continuing demand for
faster and more code-efficient microcontrollers. It executes a superset of
the original Z8^® instruction set. The eZ8 CPU features include:
• Direct register-to-register architecture allows each register to function
as an accumulator, improving execution time and decreasing the
required Program Memory
• Software stack allows greater depth in sub-routine calls and interrupts
more than hardware stacks
• Compatible with existing Z8 code
• Expanded internal Register File allows access up to 4 KB
• New instructions improve execution efficiency for code developed
using higher-level programming languages including C
• Pipelined instruction fetch and execution
• New instructions for improved performance including BIT, BSWAP,
BTJ, CPC, LDC, LDCI, LEA, MULT, and SRL
• New instructions support 12-bit linear addressing of the register file
• Up to 10 MIPS operation
• C-Compiler friendly
• Two to nine clock cycles per instruction
