Smart MCU aims for point-of-sale control
The AT91SAM9261 smart ARM microcontroller (SAM) is based on the ARM926EJ-S processor and is billed as the industry's first ultra-low-power deterministic microcontroller.
Controller maintains automotive system safety
With its built-in driver functions and complete monitoring system, the ATA6814 is a unique solution beneficial for all safety-relevant automotive electronics.
This sensor improves the image enhancement output, leading to greater recognition accuracy while improving the overall system performance.
Capitalising on high-performance thermal technology, the AT77C102B FingerChip sensor uses an improved thermal-sensitive layer on top of the silicon.
This improvement elevates the maximum temperature that the sensor can withstand, leading to new connection capabilities especially with direct flex report.

Flash microcontroller meets USB specs
Atmel has been granted certification by the USB Implementers Forum (USB-IF) for its AT91SAM7S64 ARM-based 32bit Flash microcontroller.
The AT77C102B is also RoHS-compliant, allowing the complete migration to RoHS for all sensors in the FingerChip product range.
"The FingerChip sensors already provide a very good fit to physical access control or point-of-sale application requirements thanks to their high robustness, low power consumption and high resistance to environmental constraints such as dirt, humidity or extreme temperatures", said David Richard, Atmel's Biometrics Marketing Manager.
"The AT77C102B improves the image quality output by the sensor".
"Its full compatibility with its predecessor will make it easy to implement for our current customers while new prospects will appreciate the performance of the sensor".
Atmel's FingerChip product range is a family of high-performance silicon thermal technology of CMOS fingerprint sensors using an Atmel-patented swipe sensor process and is dedicated to embedded applications.
FingerChip sensors provide high-quality images despite impairments such as wet, dry or worn-out fingerprints.
The AT77C102B's sensor measures 0.4 x 14mm in area with a resolution of 500dot/in, using chip-onboard package assembly to facilitate the ease of integration.
Its protective coating ensures excellent reliability, mechanical robustness (more than four million swipes) and a wide range of operating conditions (-40 to +85C).
The AT77C102B operates with very low power consumption (as low as 5mA for image acquisition, less than 10uA in standby mode) which is vital for battery-operated devices and embedded applications.
Atmel designed this FingerChip sensor to provide an ultrasmall form factor minimal sensing area to meet the demand of Biometric security applications.
The AT77C102B also operates well under drastic environmental conditions such as extreme temperatures, high humidity, dirt, oil and water contaminations.
The AT77C102B allows for a reliable authentication method to prevent a device from being used by unauthorised people.
Fingerprint authentification ensures protection of buildings, confidential data, and personal information, by granting access only to authorised users.
The AT77C102B is well suited for high-level applications such as physical access control, point of sales, USB biometric readers of storage devices, PC addons, to name just a few.
The AT77C102B is in production and available with either an elastomer or flex connector.
