High-performance, Low-power AVR? A complete document is available on our Web site at www. Min and Max values will be available after the device is characterized. By executing powerful instructions in a single clock cycle, the ATmega16 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed. Figure 2. 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 Power-down mode saves the register contents but freezes the Oscillator, disabling all other chip functions until the next External Interrupt 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. This allows very fast start-up combined with low-power consumption. 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. PA0 Digital supply voltage. Port pins can provide internal pull-up resistors selected for each bit. The Port A output buffers have symmetrical 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. 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 Port C PC 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 D PD 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 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 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. For compatibility with future devices, reserved bits should be written to zero if accessed. Some of the Status Flags are cleared by writing a logical one to them. Rr Rd?

Load Indirect and Pre-Dec. Store Indirect and Pre-Dec. Also Halide free and fully Green. Dimensions D1 and E1 do not include mold protrusion. Allowable protrusion is 0.

Dimensions D1 and E1 are maximum plastic body size dimensions including mold mismatch. Lead coplanarity is 0. Dimensions D and E1 do not include mold Flash or Protrusion. Mold Flash or Protrusion shall not exceed 0. M The revision letter in this section refers to the revision of the ATmega16 device. First Analog Comparator conversion may be delayed? Interrupts may be lost when writing the timer registers in the asynchronous timer? First Analog Comparator conversion may be delayed If the device is powered by a slow rising VCC, the first Analog Comparator conversion will take longer than expected on some devices.

Interrupts may be lost when writing the timer registers in the asynchronous timer If one of the timer registers which is synchronized to the asynchronous timer2 clock is written in the cycle before a overflow interrupt occurs, the interrupt may be lost. Data to succeeding devices are replaced by all-ones during Update-DR. If the Device IDs of all devices in the boundary scan chain must be captured simultaneously, the ATmega16 must be the fist device in the chain.
