The Idle mode stops the CPU while allowing the SRAM, Timer/Counters, SPI ports, CAN,
LIN/UART and interrupt system to continue functioning. The Power-down mode saves the regis-
ter contents but freezes the Oscillator, disabling all other chip functions until the next interrupt or
Hardware Reset. The ADC Noise Reduction mode stops the CPU and all I/O modules except
ADC, to minimize switching noise during ADC conversions. In Standby mode, the Crystal/Reso-
nator Oscillator is running while the rest of the device is sleeping. This allows very fast start-up
combined with low power consumption.
The device is manufactured using Atmel’s 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 nonvolatile 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 operation. 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 ATmega16M1/32M1/64M1 AVR is supported with a full suite of program and system devel-
opment tools including: C compilers, macro assemblers, program debugger/simulators, in-circuit
emulators, and evaluation kits.
Digital supply voltage.
Ground.
Port B is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The
Port B output buffers have symmetrical drive characteristics with both high sink and source
capability. As inputs, Port B pins that are externally pulled low will source current if the pull-up
resistors are activated. The Port B pins are tri-stated when a reset condition becomes active,
even if the clock is not running.
Port B also serves the functions of various special features of the ATmega16M1/32M1/64M1 as
listed on
Port C is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The
Port C output buffers have symmetrical drive characteristics with both high sink and source
capability. As inputs, Port C pins that are externally pulled low will source current if the pull-up
resistors are activated. The Port C pins are tri-stated when a reset condition becomes active,
even if the clock is not running.
