ATMEGA16M1

8-bit Microcontroller with 16K/32K/64K Bytes In-System Programmable Flash

Atmel Corporation 

Atmel ATmega16/32/64/M1/C1

The ATmega16/32/64/M1/C1 provides the following features: 16K/32K/64K bytes of In-System

Programmable Flash with Read-While-Write capabilities, 512/1024/2048 bytes EEPROM,

1024/2048/4096 bytes SRAM, 27 general purpose I/O lines, 32 general purpose working regis-

ters, one Motor Power Stage Controller, two flexible Timer/Counters with compare modes and

PWM, one UART with HW LIN, an 11-channel 10-bit ADC with two differential input stages with

programmable gain, a 10-bit DAC, a programmable Watchdog Timer with Internal Individual

Oscillator, an SPI serial port, an On-chip Debug system and four software selectable power sav-

ing modes.

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 pro-

gram 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 ATmega16/32/64/M1/C1 is a powerful microcontroller that provides a

highly flexible and cost effective solution to many embedded control applications.

The ATmega16/32/64/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.

2.2 Automotive Quality Grade

The ATmega16/32/64/M1/C1 have been developed and manufactured according to the most

stringent requirements of the international standard ISO-TS-16949. This data sheet contains

limit values extracted from the results of extensive characterization (Temperature and Voltage).

The quality and reliability of the ATmega16/32/64/M1/C1 have been verified during regular prod-

uct qualification as per AEC-Q100 grade 1.

As indicated in the ordering information paragraph, the products are available in only one tem-

perature grade.
