   ATmega169: Low power LCD device

Among the brand new features in this device is a LCD interface! (25x4). The Device is only available in a 64-pin TQFP, and have 53 general IO lines and in addition a input only pin is added to the RESET pin. (making it the AVR with most IO lines!)
Another interesting feature is the possibility of generating interrupt on 17 external pins! This is 5 more than ATtiny26 which rank #2 on the external interrupts rating. The memories are 16kB Flash, 512B EE and 1kB SRAM, in other words a standard 16k memory configuration.
Another very interesting feature is that this device runs @ 1.8V and contains an ADC. Because of the low voltage, the internal voltage reference on this device is 1.1V compared to 2.56V on all other AVRs.
The ATmega169 is also very power efficient. From the datasheet: -Active Mode:    1 MHz, 1.8V: 300µA   32 kHz, 1.8V: 20µA (including Oscillator)   32 kHz, 1.8V: TBD (including Oscillator and LCD) -Power-down Mode:    0.5µA at 1.8V
