eZ8 CPU Features
10-Bit Analog-to-Digital Converter
The eZ8 CPU, Zilog’s latest 8-bit Central Processing Unit (CPU), meets the continuing
demand for faster and more code-efficient microcontrollers. The eZ8 CPU executes a
superset of the original Z8
For more information on eZ8 CPU, refer to eZ8 CPU Core User Manual (UM0128) avail-
able for download at www.zilog.com.
The optional analog-to-digital converter (ADC) converts an analog input signal to a 10-bit
binary number. The ADC accepts inputs from eight different analog input pins in both
single-ended and differential modes. The ADC also features a unity gain buffer when high
input impedance is required.

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.
