Ethernet interface

10/100BaseT Ethernet, Auto-MDIX, magnetics not built-in

Serial ports

One port, CMOS-level.

UART capabilities

Baudrates of up to 460,800bps;

none/even/odd/mark/space parity and 7/8 bits/character (7 bits/character and "none" parity cannot be used together).

Number of I/O lines

Ten I/O lines: eight GPIO lines, plus the TX and RX lines of the serial port;

the GPIO lines are combined into an 8-bit port;

two GPIO lines can be used as interrupt lines;

I/O lines are NOT 5V-tolerant.

Max. load current for each I/O line

10mA

Flash memory

512KB, 224KB are available to store a compiled Tibbo BASIC/C application;

this memory can not be used as a flash disk.

EEPROM

2,048 bytes, 2,016 bytes are available to store application data.

The typical write endurance is about 1,000,000 write cycles per 8-byte EEPROM sector. See Prolonging and Estimating EEPROM life.
