CPU and Peripheral Overview
General Purpose Input/Output
Flash Controller
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:
•
•
•
•
•
•
•
•
•
•
•
For more information about the eZ8 CPU, refer to the
(UM0128), which is available for download on www.zilog.com.
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.
The Flash Controller programs and erases the Flash memory. It also supports protection
against accidental programming and erasure.
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 4 KB
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
