eZ8 CPU Features
General-Purpose I/O
Flash Controller
The eZ8 CPU, Zilog’s latest 8-bit central processing unit (CPU), meets the continuing
demand for faster and code-efficient microcontrollers. The eZ8 CPU executes a superset
of the original Z8

Z8 Encore! XP F0823 Series features 6 to 24 port pins (Ports A–C) for general-purpose
I/O (GPIO). The number of GPIO pins available is a function of package. Each pin is
individually programmable. 5 V tolerant input pins are available on all I/Os on 8-pin
devices, most I/Os on other package types.
The Flash Controller programs and erases Flash memory. The Flash Controller supports
protection against accidental program and erasure, as well as factory serialization and read
protection.
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 much greater depth in subroutine calls and interrupts than
hardware stacks.
Compatible with existing Z8 code.
Expanded internal Register File allows access of 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.
2 to 9 clock cycles per instruction.
