Overview of ATMEGA128-16AU

The ATMEGA128-16AU has the following capabilities: 128Kbytes of In-System Programmable Flash with Read-While-Write capabilities, 4Kbytes EEPROM, 4Kbytes SRAM, 53 general-purpose I/O lines, 32 general-purpose working registers, Real-Time Counter (RTC), four flexible Timer/Counters with compare modes and PWM, two USARTs, a byte-oriented Two-wire Serial Interface, an 8-channel, 10-bit ADC with optional differential input stage with programmable gain, programming The CPU is turned off in Idle mode, while the SRAM. Timer/Counters, SPI interface, and interrupt system continue to work.

The Oscillator is frozen in the Power-down mode, which disables all other chip functions until the next interrupt or Hardware Reset. The asynchronous timer continues to run in Power-save mode, allowing the user to keep a timer base while the rest of the device sleeps. To reduce switching noise during ADC conversions, the ADC Noise Reduction mode turns off the CPU and all I/O modules except the Asynchronous Timer and ADC, The Crystal/Resonator Oscillator runs in Standby mode while the rest of the device sleeps. This enables for a very quick start-up while also consuming extremely little power. Both the main Oscillator and the Asynchronous Timer continue to run in Extended Standby mode.
