A — Power-down Mode: 0. It should be soldered or glued to the board to ensure good mechanical stability. If the center pad is left unconnected, the package might loosen from the board. Disclaimer Typical values contained in this datasheet are based on simulations and characterization of other AVR microcontrollers manufactured on the same process technology.

Block Diagram Figure 4. Block Diagram PF 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 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. Table 2 summarizes the different configurations for the six devices. Table 2. PA0 Digital supply voltage. The Port A output buffers have symmetrical drive characteristics with both high sink and source capability. As inputs, Port A pins that are externally pulled low will source current if the 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. Port B PB 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 has better driving capabilities than the other ports. 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. The Port D pins are tri-stated when a reset condition becomes active, even if the clock is not running. Port E PE 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. Port F PF Port pins can provide internal pull-up resistors selected for each bit.

The Port F output buffers have symmetrical drive characteristics with both high sink and source capability. As inputs, Port F pins that are externally pulled low will source current if the pull-up resistors are activated. The Port F pins are tri-stated when a reset condition becomes active, even if the clock is not running. Port G PG The Port G output buffers have symmetrical drive characteristics with both high sink and source capability.

As inputs, Port G pins that are externally pulled low will source current if the pull-up resistors are activated. The Port G pins are tri-stated when a reset condition becomes active, even if the clock is not running. Port H PH The Port H output buffers have symmetrical drive characteristics with both high sink and source capability. As inputs, Port H pins that are externally pulled low will source current if the pull-up resistors are activated.

The Port H pins are tri-stated when a reset condition becomes active, even if the clock is not running. Port J PJ The Port J output buffers have symmetrical drive characteristics with both high sink and source capability. As inputs, Port J pins that are externally pulled low will source current if the pull-up resistors are activated.

The Port J pins are tri-stated when a reset condition becomes active, even if the clock is not running. Port K PK The Port K output buffers have symmetrical drive characteristics with both high sink and source capability. As inputs, Port K pins that are externally pulled low will source current if the pull-up resistors are activated. The Port K pins are tri-stated when a reset condition becomes active, even if the clock is not running. Port L PL The Port L output buffers have symmetrical drive characteristics with both high sink and source capability.

As inputs, Port L pins that are externally pulled low will source current if the pull-up resistors are activated. The Port L pins are tri-stated when a reset condition becomes active, even if the clock is not running.

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 26 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. This device can also be supplied in wafer form. Please contact your local Atmel sales office for detailed ordering information and minimum quantities.

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. Inaccurate ADC conversion in differential mode with x gain? High current consumption in sleep mode 1. Typical absolute accuracy may reach 64 LSB. High current consumption in sleep mode. If a pending interrupt cannot wake the part up from the selected sleep mode, the current consumption will increase during sleep when executing the SLEEP instruction directly after a SEI instruction.

ATmega rev. E No known errata. D Not sampled. B Not sampled. Non-Read-While-Write area of flash not functional Part does not work under 2. The problem is related to the speed of the part when reading the flash of this area. Part does not work under 2.

It can give up to 7 LSB error. The result when doing later conversions can then be calibrated. The referring revision in this section are referring to the document revision. Updated Table 1 on page 3.
