Low-power CMOS 8-bit AVR microcontroller in lead-free 40-pin PDIP

By executing powerful instructions in a single clock cycle, the ATmega16 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.

Features include 16 KBytes of In-System Programmable Flash with Read-While-Write capabilities, 512 Bytes EEPROM, 1 KByte SRAM, 32 general-purpose I/O lines, 32 general-purpose working registers, a JTAG interface for Boundary-scan On-chip Debugging support and programming, three flexible Timer/Counters with compare modes, internal and external interrupts, a serial programmable USART, a Byte-oriented Two-wire serial interface, an 8-channel 10-bit ADC, a programmable Watchdog Timer with Internal Oscillator, an SPI serial port, and six software-selectable power saving modes:

• Idle Mode stops the CPU while allowing the USART, Two-wire interface, SRAM, Timer/Counters, SPI port, and interrupt system to continue functioning.
• Power-Down Mode saves the register contents but freezes the Oscillator, disabling all other chip functions until the next external interrupt or Hardware Reset.
• Power-Save Mode in which the Asynchronous Timer continues to run, allowing you to maintain a timer base while the rest of the device is sleeping.
• ADC Noise Reduction Mode stops the CPU and all I/O modules except Asynchronous Timer, to minimize switching noise during A/D conversions.
• Standby Mode in which the crystal/resonator Oscillator is running while the rest of the device is sleeping. This allows very fast start-up combined with low-power consumption.
• Extended Standby Mode in which both the main Oscillator and the Asynchronous Timer continue to run.
