ATmega16M1/32M1/64M1 [DATASHEET]
8209ES–AVR–11/2012
CPU and all I/O modules except ADC, to minimize switching noise during ADC conversions. In Standby mode, the
Crystal/Resonator Oscillator is running while the rest of the device is sleeping. This allows very fast start-up com-
bined with low power consumption.
The device is manufactured using the Atmel high-density nonvolatile memory technology. The On-chip ISP Flash
allows the program memory to be reprogrammed in-system through an SPI serial interface, by a conventional non-
volatile memory programmer, or by an On-chip Boot program running on the AVR core. The boot program can use
any interface to download the application program in the application Flash memory. Software in the Boot Flash
section will continue to run while the Application Flash section is updated, providing true Read-While-Write opera-
tion. By combining an 8-bit RISC CPU with In-System Self-Programmable Flash on a monolithic chip, the Atmel
ATmega16M1/32M1/64M1 is a powerful microcontroller that provides a highly flexible and cost effective solution to
many embedded control applications.
The Atmel ATmega16M1/32M1/64M1 AVR is supported with a full suite of program and system development tools
including: C compilers, macro assemblers, program debugger/simulators, in-circuit emulators, and evaluation kits.
