General Purpose I/O
The Z8 Encore!^® features seven 8-bit ports (Ports A-G) and one 4-bit port (Port H) for
general purpose I/O (GPIO). Each pin is individually programmable.
Flash Controller
The Flash Controller programs and erases the Flash memory.
10-Bit Analog-to-Digital Converter
The Analog-to-Digital Converter (ADC) converts an analog input signal to a 10-bit binary
number. The ADC accepts inputs from up to 12 different analog input sources.
UARTs
Each UART is full-duplex and capable of handling asynchronous data transfers. The
UARTs support 8- and 9-bit data modes and selectable parity.
I²C
The inter-integrated circuit (I²C^®) controller makes the Z8 Encore!^® compatible with the
I²C protocol. The I²C controller consists of two bidirectional bus lines, a serial data (SDA)
line and a serial clock (SCL) line.
