Keywords:ZiLOG? ARRIS? Z8 Encore!? microcontroller? MCU?

ZiLOG Inc. announced that international communications technology provider ARRIS has selected its Z8 Encore! XP microcontroller (MCU) for use in the design of its next-generation Embedded Multimedia Terminal Adaptor (E-MTA) with Voice over IP (VoIP), the Touchstone Telephony Modem TM502.

Delivering two lines of primary line VoIP along with high-speed data access, the ARRIS TM502 E-MTA uses the Z8 Encore! XP 4k (part number Z8F042AHJ020SG) to manage the functional block dedicated to monitoring, testing and charging the unit's batteries, enabling cable operators to offer either four hours or eight hours of uninterrupted telephony service during power outages.

According to ZiLOG, the integration of a high speed analog-to-digital converter on-chip was a major contributory factor in ARRIS selecting the Z8 Encore! 4k, as this plays an important role, offering 14 bits of resolution, which is required to maintain the integrity of the Li-ion in the battery block. In addition, ARRIS made full use of the Encore! XP's other on-chip peripherals, such as the temperature sensor and op amplifier, which also tied into the operation of the battery block and reduced the BOM and external component count, resulting in a reduction in overall system cost.

"The battery-charging block is a key area of differentiation with the TM502 E-MTA, and the technology ARRIS developed using the Z8 Encore! XP is an important element of this differentiation," said ZiLOG CEO and Chairman Jim Thorburn. "Our overall system cost and product offering in this area was the strongest and these factors, coupled with the levels of support offered by our engineers to help the customer develop their product, were precisely why we succeeded over our main competitors, including the incumbent supplier."
