CPU and Peripheral Overview
The eZ8 CPU, Zilog’s latest 8-bit CPU, meets the continuing demand for faster and more
code-efficient microcontrollers. The eZ8 CPU 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 accumula-
tor, improving execution time and decreasing the required program memory
• Software stack allows much greater depth in subroutine calls and interrupts than hard-
ware stacks
• Compatible with existing Z8 CPU code
• Expanded internal register file allows access up to 4KB
• New instructions improve execution efficiency for code developed using high-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
• 2 to 9 clock cycles per instruction
For more information about the eZ8 CPU, refer to the eZ8 CPU Core User Manual
(UM0128), which is available for download on www.zilog.com.
General Purpose Input/Output
The Z8 Encore! F0830 Series features up to 25 port pins (Ports A–D) for general-purpose
input/output (GPIO). The number of GPIO pins available is a function of package. Each
pin is individually programmable.
Flash Controller
The Flash Controller programs and erases the Flash memory. It also supports protection
against accidental programming and erasure.
