General Purpose I/O
The 64K Series features seven 8-bit ports (Ports A-G) and one 4-bit port (Port H) for gen-
eral purpose I/O (GPIO). Each pin is individually programmable. All ports (except B and
H) support 5V-tolerant inputs.
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, selectable parity, and an efficient bus transceiver
Driver Enable signal for controlling a multi-transceiver bus, such as RS-485.
