tions. The operating temperature range is –40°C to 105°C.
The AMT21 and AMT23 encoders also are highly customiz-
able and configurable, with the ability to program the direction
of rotation and zero position via CUI’s AMT Viewpoint soft-
ware. The design of the encoders also reduces the time that it
takes to mount and align (to seconds) thanks to the One Touch
Zero feature.

LUMILEDS

LUXEON 5050
http://www.lumileds.com
Lumileds introduced
an upgraded LUXEON
5050 that sets the stan-
dard for high lumens per
watt (lm/W) for high-bay and
street-lighting applications. The
LUXEON 5050 features the best
performance of all multi-die emitters on the market, according
to Lumileds, reaching flux levels of 350 lm and 175 lm/W at
2-W LED drive conditions (4,000K, 70CRI at 85°C).
But the advantage goes beyond superior flux, said Lu-
mileds. The round LES (4.6 mm) eases optic design. With the
industry’s lowest thermal resistance (2K/W), the LUXEON
5050 further enhances performance by removing heat and
reducing heat sink requirements.
The LUXEON 5050 is available in a range of color
temperatures (2,700K–6,500K) and CRI levels (70, 80, 90)
to meet a variety of high bay and street lighting as well as
indoor spotlighting.
Typically for high-lumen fixtures that require a high
lm/W, a group of standard mid-power LEDs would be used.
By using the LUXEON 5050, it enables an overall smaller

system, which can reduce the size and weight of the fixtures.

With newly released LM-80 reliability data, the product also

meets DLC Premium V4.1 requirements, giving fixture man-

ufacturers access to high utility rebates and energy savings.

MICROCHIP TECHNOLOGY

SAMA5D2 System-on-Module

http://www.microchip.com

There is extensive design effort and complexity associated with

creating an industrial-grade MPU-based system running a

Linux operating system, said Microchip, and even experienced

developers spend a lot of time on PCB layout to guarantee sig-

nal integrity for the high-speed interfaces to DDR memory and

Ethernet PHY while complying with EMC standards.

The SAMA5D2 system-on-module (SOM) simplifies design

by integrating the power management, non-volatile boot mem-

ory, Ethernet PHY, and high-speed DDR2 memory on a small,

single-sided PCB. Microchip’s SAMA5D2 SOM is a single-sided

PCB with 169 components including the Arm Cortex-A5–

based SAMA5D2 SiP that integrates DDR2 memory in a single

package, simplifying designs by removing high-speed memory

interface constraints

from a PCB.

The SAMA5D2

SOM is industrial-cer-

tified and features

the highest levels of

security in the industry,

including PCI compli-

ance. It comes integrat-

ed with Arm Trust-

Zone and capabilities
