Atmel Adds USB and OTG to Its Range of AVR Flash MCU

Nantes, France (ots/PRNewswire)

- A Combination of Versatile Interfaces, USB On-The-Go and
Flexibility
Atmel(R) Corporation (Nasdaq: ATML), a global leader in the
development and fabrication of advanced semiconductor solutions,
announced today four new AVR(R) Flash MCUs with USB controller. The
AT90USB microcontrollers are designed to address the varied
requirements of embedded applications needing USB connectivity in
host and function modes.
There are more than 1 billion USB devices in use and after
conquering computers and peripherals, USB is gaining momentum in
consumer products and industrial equipment. Data storage, data
transfer, product configuration and firmware updates are key
applications driving this trend.
The AT90USB1286 and AT90USB646 have USB interface for applications
needing to communicate with USB host. The AT90USB1287 and AT90USB647
comply with the USB On-The-Go (OTG) standard for use as Dual Role
Devices (DRD) in applications operating as either host or function on
the USB. The USB host capability is key to embedded devices needing
to communicate without PC intervention.
The AT90USB1286 and AT90USB1287 have 128 Kbytes of In-System
Programmable (ISP) Flash, 8 Kbytes of RAM and 4 Kbytes of EEPROM. The
AT90USB646 and AT90USB647 are identical but with half the memory
size. All devices have an on-chip bootloader that allows ISP through
the USB bus providing unrivalled flexibility from development phase
to field update.
A new USB controller has been developed to support all USB modes
and OTG it can be configured to operate in low speed at 1.5 Mbit/s or
full speed at 12 Mbit/s. Low speed allows support for a wide range of
low-cost devices like mice and keyboards while full speed is
sufficient to transfer Mbytes in seconds. Up to one control and six
data endpoints/pipes can be configured simultaneously with a maximum
packet size of 64 bytes. The maximum packet size can be extended to a
maximum of 256 bytes, for time critical "isochronous" transfers with
the first data endpoint /pipe. Near maximum USB bandwidth can be
achieved with double buffering, without any real-time constraints
when the AVR MCU runs at 8 MHz.
On-chip PLL with an external crystal of 2 MHz to 16 MHz provides a
48 MHz clock for USB operation. The new AVR microcontrollers can
operate at 8 MHz with a supply voltage of 3V for battery powered
applications. In this case, a typical power consumption of less than
20 mA is measured with the USB host in action. The devices can also
be USB powered at 5V and operate up to 16 MHz.
All devices include a hardware multiplier, one USART, one SPI, one
TWI, two 8-bit and two 16-bit timers with PWM and RTC, 8-channel
10-bit ADC with differential inputs, a programmable gain amplifier
and 48 programmable I/Os.
An extensive software library is offered to support the
most-relevant USB classes for the embedded market: Mass Storage
Device (MSD), Human Interface Device (HID), Device Firmware Upgrade
(DFU), Communication Device Class (CDC), Audio Class, etc.
Evaluation and debug tools are available now. The STK525 Starter
Kit, selling at US$199, can be used in stand-alone mode and
demonstrate all the above mentioned device classes. It can also be
used as an adapter to the generic STK500. The AVR USB Key, selling at
US$29.99, is a very low-cost evaluation tool demonstrating human
interface, mass storage and OTG capability. It can be reprogrammed in
less than five seconds through the USB interface. JTAGICE MkII can
connect to the starter kits and to the USB key for in-system
programming and emulation through On-Chip Debug resources (OCD).
AT90USB1287 will be used for sampling and development for the whole
AT90USB family including devices yet to be announced.
AT90USB1286 is available now in a QFN64 package at US$5.80 for 10k
units. AT90USB1287 is sampling in QFN64 and TQFP64 packages at
US$6.20 in quantities of 10k. AT90USB647 and AT90USB646 will be
available later in 2006 at US$4.60 and US$4.20, respectively, for 10k
units.
