Summary

Rev. 2466TS–AVR–07/10

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 con-

ventional CISC microcontrollers.

The ATmega16 provides the following features: 16 Kbytes of In-System Programmable Flash

Program memory with Read-While-Write capabilities, 512 bytes EEPROM, 1 Kbyte SRAM, 32

general purpose I/O lines, 32 general purpose working registers, a JTAG interface for Boundary-

scan, On-chip Debugging support and programming, three flexible Timer/Counters with com-

pare modes, Internal and External Interrupts, a serial programmable USART, a byte oriented

Two-wire Serial Interface, an 8-channel, 10-bit ADC with optional differential input stage with

programmable gain (TQFP package only), a programmable Watchdog Timer with Internal Oscil-

lator, an SPI serial port, and six software selectable power saving modes. The Idle mode stops

the CPU while allowing the USART, Two-wire interface, A/D Converter, SRAM, Timer/Counters,

SPI port, 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 External Inter-

rupt or Hardware Reset. In Power-save mode, the Asynchronous Timer continues to run,

allowing the user to maintain a timer base while the rest of the device is sleeping. The ADC

Noise Reduction mode stops the CPU and all I/O modules except Asynchronous Timer and

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. In Extended Standby mode, both the main Oscillator

and the Asynchronous Timer continue to run.

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 ATmega16 is a powerful microcontroller that provides a highly-flexible and cost-effec-

tive solution to many embedded control applications.

The ATmega16 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.

Pin Descriptions

VCC

GND

Port A (PA7..PA0)

Digital supply voltage.

Ground.

Port A serves as the analog inputs to the A/D Converter.

Port A also serves as an 8-bit bi-directional I/O port, if the A/D Converter is not used. Port pins

can provide internal pull-up resistors (selected for each bit). The Port A output buffers have sym-

metrical drive characteristics with both high sink and source capability. When pins PA0 to PA7

are used as inputs and are externally pulled low, they will source current if the internal pull-up

resistors are activated. The Port A pins are tri-stated when a reset condition becomes active,

even if the clock is not running.

ATmega16(L)

2466TS–AVR–07/10

ATmega16(L)

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 ATmega16 as listed on

page

58.

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. If the JTAG interface is enabled, the pull-up resistors on pins

PC5(TDI), PC3(TMS) and PC2(TCK) will be activated even if a reset occurs.

Port C also serves the functions of the JTAG interface and other special features of the

ATmega16 as listed on

page 61.

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, 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 ATmega16 as listed on

page

63.

RESET

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

Table 15 on page

38.

Shorter pulses are not guaranteed to generate a reset.

Input to the inverting Oscillator amplifier and input to the internal clock operating circuit.

Output from the inverting Oscillator amplifier.

AVCC is the supply voltage pin for Port A and the A/D Converter. It should be externally con-

nected to V

, even if the ADC is not used. If the ADC is used, it should be connected to V

through a low-pass filter.

AREF is the analog reference pin for the A/D Converter.
