Atmel Receives ZigBee RF4CE Platform Certification Using ATmega128RFA1

Enables faster, more reliable RF remotes and provides freedom to operate devices Removing ‘line-of-sight’ barrier of today’s infrared remotes

LAS VEGAS, Jan. 7 /PRNewswire-FirstCall/ — CES — Atmel® Corporation (Nasdaq: ATML), a leader in touch- and microcontroller-based solutions, today announced that Atmel’s RF4Control platform has received ZigBee® RF4CE certification using the new ATmega128RFA1 wireless AVR® microcontroller. Atmel can now offer its customers an immediate, low-cost, easy-to-implement solution for various remote control applications using the ATmega128RFA1.

The ZigBee RF4CE specification is a standardized specification for radio frequency (RF) remote controls promoted by the ZigBee Alliance. The specification enables flexible control from nearby rooms, enables unique two-way communications between the remote and device, and delivers improved remote battery life for a variety of consumer electronic (CE) devices such as HDTV, home theater equipment, set-top boxes and other audio equipment.

“We are pleased to be among the first to have our wireless platform ZigBee RF4CE certified,” said Magnus Pedersen, product marketing director of MCU wireless solutions at Atmel Corporation. “With this certification, Atmel’s recently launched ATmega128RFA1 can now offer customers more flexibility, reliability and freedom to operate their devices from greater distances. The two-way communication between the device and remote, and by removing the ‘line-of-site’ barrier, enables our consumers to enjoy an even richer experience.”

“The certification of Atmel’s RF4Control platform is another step towards spreading ZigBee’s reach in homes everywhere,” said Benno Ritter, vice president of marketing for the ZigBee Alliance. “ZigBee RF4CE will offer manufacturers a number of advanced remote control features while offering increased flexibility and ease of use.”

“As the authorized ZigBee test lab, we are pleased to certify Atmel’s ATmega128RFA1 to develop products based on the RF4CE standard,” said Osman Sakr, chief technology officer of National Technical Systems Inc. “We look forward to testing more products and platforms to move towards interoperable RF products across multiple vendors based on this new standard.”

The Latest in Pyroshock Testing Techniques

by Vesta I. Bateman, Chair, IEST Working Group DTE032

The IEST Recommended Practice on pyroshock testing has been revised and updated to reflect advances in the art of pyroshock testing and to address common problems related to data accuracy in the pyroshock community. The key changes to IEST-RP-DTE032: Pyroshock Testing Techniques are described here.

New definitions for near-field pyroshock, mid-field pyroshock, and far-field pyroshock adopted by IEST-RP-DTE032.2 are consistent with the definitions given in MIL-STD-810G, Method 517, as shown in the table and the spectra definitions below. The definitions and table values are quantified in terms of shock response spectra (SRS). The SRS, with an appropriate damping value, is the most widely used tool to analyze pyroshock data and is calculated using acceleration measurements near components and subsystems that must be qualified separately. The Jet Propulsion Laboratory will be revising NASA-STD-7003 during the coming year, and the current NASA values for near-field, mid-field, and far-field pyroshock are also shown in the table.

A near-field pyroshock test requires frequency control up to and above 10 kHz for amplitudes greater than 10,000 g. A pyrotechnically excited simulation technique is usually appropriate, although in some cases a mechanically excited simulation technique may be used.

A mid-field pyroshock test requires frequency control from 3 kHz to 10 kHz for amplitudes less than 10,000 g. A mechanically excited simulation technique other than shaker shock is usually required.

A far-field pyroshock test requires frequency control no higher than 3 kHz for amplitudes less than 1,000 g. A shaker shock or a mechanically excited simulation technique is appropriate.
