Monday, March 09, 2009: Atmel Corporation has introduced a new family
of tinyAVR microcontrollers. These AVR devices are targeted at
applications that run from a single battery, such as AA, AAA, or coin
cell. The first member of this family is the ATtiny43U which is a
perfect fit for portable battery powered consumer applications like
phone accessories, remote controls, sporting goods and personal care
products. ATtiny43U has 4-Kbytes of Flash memory and 64 bytes of
In-System programmable EEPROM.

A regular AA or AAA battery has a voltage of up to 1.8V fully charged.
When energy is drawn from the battery, the battery voltage drops as the
battery discharges, down to 0.7V where there is hardly any energy at
all left in the battery. The ATtiny43U has an on-chip boost regulator
that works from battery voltages between 0.7 and 1.8V. The regulator
converts the low battery voltage up to 3V, this is sufficiently high to
effectively operate the AVR MCU, its peripherals and I/Os. The boost
regulator can deliver enough current to the I/O pins to directly drive
LEDs and electric motors. The ATtiny43U also features a 10-bit ADC, two
8-bit timer counters with PWM outputs, SPI, I2C interface, internal
temperature sensor, and has up to 8 MIPS throughput running from a 0.7V
battery.

"With
the introduction of the ultra low voltage tinyAVR microcontrollers we
are expanding the popular AVR product family into a new market segment.
The ATtiny43U features an internal regulator that removes the need for
multiple batteries or complex external boost regulators, this reduces
the physical size, time to market, and bill of material for battery
powered applications," said Jukka Eskelinen, director, tinyAVR product
marketing, Atmel.

The ATtiny43U features an on-chip debug system
for easy and fast development. All tinyAVR microcontrollers use the
standard AVR microcontroller development tools. 
 
Samples for the ATtiny43U are available now in a QFN20 package. Volume prices for 10k units are $1.00.
