Overview The Atmel ATmega16M1/32M1/64M1 is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATmega16M1/32M1/64M1 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.

ALU HW LIN/UART Timer 0 Timer 1 Data SRAM ADC EEPROM DAC I/O lines MPSC Current source CAN The AVR core combines a rich instruction set with 32 general purpose working registers. All the 32 registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two independent registers to be accessed in one single instruction executed in one clock cycle. The resulting architecture is more code efficient while achieving throughputs up to ten times faster than conventional CISC microcontrollers. The Atmel ATmega16M1/32M1/64M1 provides the following features: 16/32/64Kbytes of In-System Programmable Flash with Read-While-Write capabilities, 512B/1K/2Kbytes EEPROM, 1/2/4Kbytes SRAM, 27 general purpose I/O lines, 32 general purpose working registers, one Motor Power Stage Controller, two flexible Timer/Counters with compare modes and PWM, one UART with HW LIN, an 11channel 10-bit ADC with two differential input stages with programmable gain, a 10-bit DAC, a Atmel ATmega16M1/32M1/64M1 [DATASHEET] Atmel-8209F-ATmega16M1/32M1/64M1_Datasheet_Summary-10/2016 10 programmable Watchdog Timer with Internal Individual Oscillator, an SPI serial port, an On-chip Debug system and four software selectable power saving 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 register 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/Resonator 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 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 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 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. 3.2. Pin descriptions 3.2.1. VCC Digital supply voltage. 3.2.2. GND Ground. 3.2.3. Port B (PB7..PB0) 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 Alternate Functions of Port B. Refer to Alternate Functions of Port B for details. 3.2.4. Port C (PC7..PC0) 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. Port C also serves the functions of special features of the ATmega16M1/32M1/64M1 as listed in Alternate Functions of Port C. Refer to Alternate Functions of Port C for details. 3.2.5. Port D (PD7..PD0) Port D is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The Port D output buffers have symmetrical drive characteristics with both high sink and source capability. As inputs, Atmel ATmega16M1/32M1/64M1 [DATASHEET] Atmel-8209F-ATmega16M1/32M1/64M1_Datasheet_Summary-10/2016 11 Port D pins that are externally pulled low will source current if the pull-up resistors are activated. The Port D pins are tri-stated when a reset condition becomes active, even if the clock is not running. Port D also serves the functions of various special features of the Atmel ATmega16M1/32M1/64M1 as listed in Alternate Functions of Port D. Refer to Alternate Functions of Port D for details. 3.2.6. Port E (PE2..0) RESET/ XTAL1/XTAL2 Port E is an 3-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The Port E output buffers have symmetrical drive characteristics with both high sink and source capability. As inputs, Port E pins that are externally pulled low will source current if the pull-up resistors are activated. The Port E pins are tri-stated when a reset condition becomes active, even if the clock is not running. If the RSTDISBL Fuse is programmed, PE0 is used as an I/O pin. Note that the electrical characteristics of PE0 differ from those of the other pins of Port E. If the RSTDISBL Fuse is unprogrammed, PE0 is used as a reset input. A low level on this pin for longer than the minimum pulse length will generate a reset, even if the clock is not running. The minimum pulse length is given in System and reset characteristics. Shorter pulses are not guaranteed to generate a Reset. Depending on the clock selection fuse settings, PE1 can be used as input to the inverting Oscillator amplifier and input to the internal clock operating circuit. Depending on the clock selection fuse settings, PE2 can be used as output from the inverting Oscillator amplifier. The various special features of Port E are elaborated in Alternate Functions of Port E. 3.2.7. AVCC AVCC is the supply voltage pin for the A/D Converter, D/A Converter, Current source. It should be externally connected to VCC, even if the ADC, DAC are not used. If the ADC is used, it should be connected to VCC through a low-pass filter. 3.2.8. AREF This is the analog reference pin for the A/D Converter. Atmel ATmega16M1/32M1/64M1 [DATASHEET] Atmel-8209F-ATmega16M1/32M1/64M1_Datasheet_Summary-10/2016 12 4.

About code examples This documentation contains simple code examples that briefly show how to use various parts of the device. Be aware that not all C compiler vendors include bit definitions in the header files and interrupt handling in C is compiler dependent. Please confirm with the C compiler documentation for more details. These code examples assume that the part specific header file is included before compilation. For I/O registers located in extended I/O map, "IN", "OUT", "SBIS", "SBIC", "CBI", and "SBI" instructions must be replaced with instructions that allow access to extended I/O. Typically "LDS" and "STS" combined with "SBRS", "SBRC", "SBR", and "CBR". Atmel ATmega16M1/32M1/64M1 [DATASHEET] Atmel-8209F-ATmega16M1/32M1/64M1_Datasheet_Summary-10/2016 14 6.
