The ATmega168V or ATmega328V on the Arduino LilyPad comes preburned with a bootloader that allows you to upload new code to it with the Arduino software. The bootloader on the most recent LilyPad boards is Limor Fried's "no wait" bootloader. When the LilyPad is supplied with power, its Arduino sketch starts immediately. The bootloader is triggered only when the reset switch is pressed. You can also bypass the bootloader and program the ATmega through the ICSP (In-Circuit Serial Programming) header; see these instructions for details.

Memory
The ATmega168 has 16 KB of flash memory for storing code (of which 2 KB is used for the bootloader). It has 1 KB of SRAM and 512 bytes of EEPROM (which can be read and written with the EEPROM library).
The Arduino Diecimila can be programmed with the Arduino software (download). For details, see the reference and tutorials.
The ATmega168 on the Arduino Diecimila comes preburned with a bootloader that allows you to upload new code to it without the use of an external hardware programmer. It communicates using the original STK500 protocol (reference, C header files).
You can also bypass the bootloader and program the ATmega168 through the ICSP (In-Circuit Serial Programming) header; see these instructions for details.
Input and Output
Each of the 14 digital pins on the Diecimila can be used as an input or output. They operate at XX volts. Each pin can provide or receive a maximum of 40 mA and has an internal pull-up resistor (disconnected by default) of 20-50 kOhms. Pins 3, 5, 6, 9, 10, and 11 can provide PWM output; for details see the analogWrite() function. If anything is connected to pins 0 and 1, it will interfere with the USB communication, preventing new code from being uploaded or other communication with the computer.
The Diecimila has 6 analog inputs, each of which provide 10 bits of resolution (i.e. 1024 different values). By default they measure from ground to 5 volts, though is it possible to change the upper end of their range using the AREF pin and some low-level code.
See also the mapping between Arduino pins and ATmega168 ports.
Communication
The LilyPad Arduino has a number of facilities for communicating with a computer, another Arduino, or other microcontrollers. The ATmega168 provides UART TTL (5V) serial communication, which is available on digital pins 0 (RX) and 1 (TX). An FTDI FT232RL on the board channels this serial communication over USB and the FTDI drivers (included with the Arduino software) provide a virtual com port to software on the computer. The Arduino software includes a serial monitor which allows simple textual data to be sent to and from the Arduino board.
A SoftwareSerial library allows for serial communication on any of the LilyPad's digital pins.
The ATmega168 also supports I2C (TWI) and SPI communication. The Arduino software includes a Wire library to simplify use of the I2C bus; see the documentation on the Wiring website for details. To use the SPI communication, please see the ATmega168 datasheet.
