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 ATmega32/64/M1/C1 is a powerful microcontroller that provides a highly flexible and
cost effective solution to many embedded control applications.
The ATmega32/64/M1/C1 AVR is supported with a full suite of program and system develop-
ment tools including: C compilers, macro assemblers, program debugger/simulators, in-circuit
emulators, and evaluation kits.
The ATmega32/64/M1/C1 have been developed and manufactured according to the most strin-
gent requirements of the international standard ISO-TS-16949 grade 1. This data sheet contains
limit values extracted from the results of extensive characterization (Temperature and Voltage).
The quality and reliability of the ATmega32/64/M1/C1 have been verified during regular product
qualification as per AEC-Q100.
As indicated in the ordering information paragraph, the products are available in only one tem-
perature grade.
