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

A Combination of Versatile Interfaces, USB On-The-Go and Flexibility

NANTES, France, Feb. 14 /PRNewswire/ -- 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 $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 $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 $5.80 for 10k units. AT90USB1287 is sampling in QFN64 and TQFP64 packages at $6.20 in quantities of 10k. AT90USB647 and AT90USB646 will be available later in 2006 at $4.60 and $4.20, respectively, for 10k units.
