The low-data wireless networking reference design targets industrial control applications, such as lighting control, AMR and point-to-point cable replacement. The design features the MICRF505 or MICRF506 , 410MHz to 950MHz ISM-Band FHSS FSK Transceivers. These devices support data rates up to 200kbps while only consuming 34mW of power in receive mode, and 70mW of power in transmit mode, while transmitting at +10dBm output power. The devices are capable of achieving a sensitivity of -113dBm at 2.4kbps. The reference design features MicrelNet™ royalty and licensing free "star-cluster" wireless networking software. The design was developed in cooperation with Zilog and features the Z8 Encore! XP F1680 microcontroller.

The Z8 Encore! XP F1680 Microcontroller Series is a family of highly integrated, low voltage/low power, high performance 8-bit mixed-mode Flash microcontrollers designed for use in a variety of RF solutions such as RFID readers, remote controls and automatic meter readers. The Z8 Encore! XP Z81680 Microcontroller Series, based on a 20 MHz register-based eZ8 CPU core with memory-to-memory arithmetic operation, includes up to 24 Kbytes Flash memory with in-circuit programming capability, up to 2 Kbytes register RAM and 256 Bytes EEPROM capability, a built-in internal precision oscillator with programmable output from 43.2 kHz to 11 MHz and multiple serial interfaces including two LIN UARTs, SPI, and I2C. This series is also a low power series, supporting 1.8-3.6 V operation with very low ACTIVE, HALT and STOP mode currents, and many power saving features.

"Zilog's Z8 Encore! XP F1680 Microcontroller Series help power a variety of RF solutions, and our collaboration with Micrel has allowed the two companies to develop an ideal solution that will save our collective customers money and time to market," said Mike Speckman, Zilog vice president of worldwide sales.

Micrel will also showcase the following products and reference designs:

Highly Integrated System-on-a-Chip Solutions, KSZ9692PB / KSZ9021RL

The KSZ9692PB is a highly integrated 10/100/100Base-T Gigabit System-on-a-Chip (SoC) featuring an ARM 922T 32-bit processor, IP security engine and a comprehensive set of peripherals that address the cost-sensitive, high-performance needs of a wide variety of networking and communications applications including enhanced residential gateways, high-end printer servers, VOIP systems, IP-based multimedia systems, wireless Access Points/Mesh Nodes, USB device servers, Industrial Control, video surveillance systems and SMB/SME network security, including VPN routers.

The KSZ9021RL is a single-port 10/100/100Base-T Gigabit transceiver that supports data transfer over standard CAT-5 unshielded twisted pair cable. The solution features robust performance and very low power consumption. The on-chip integration of termination resistors and LDO controller function, coupled with built-in diagnostic features, significantly reduces cost and complexity in gigabit Ethernet applications. The device is ideal for enabling the highest level of gigabit Ethernet performance in networking applications such as media converters, GEPON ONU routers, wired/wireless Gigabit routers and VoIP gateways.

Single-Port 10/100BASE-T/TX Embedded MAC+PHY Embedded Controller With 8/16/32-bit and SPI Host Interfaces, KSZ8851 Family

The KSZ8851 is a single-port 10/100BASE-T/TX embedded controller product family with 8/16/32-bit and SPI host interfaces. The high throughput device, KSZ8851-16/32MQL , is pin compatible with Micrel's KSZ8841-16/32MQL and KSZ8842-16/32MQL product families and ideal for a wide variety of Ethernet applications in the IPSTB, VoIP, and Industrial Ethernet markets. The KSZ8851-16MLL integrates a Fast Ethernet MAC/PHY with an 8/16-bit generic host processor interface in a smaller package and the KSZ8851SNL , on the other hand, supports SPI interface. The device has 18KB of internal buffer memory shared between the RXQ and TXQ. The buffer memory on the receive queue is 12KB, while the buffer memory for the transmit queue is 6KB. The solution supports both Big-Endian and Little-Endian processors as well as IPv4/IPv6 checksum generation and checking. These features greatly reduce CPU usage and improve overall system performance. The KSZ8851 product family also gives designers enhanced power management feature with energy detect mode.

Integrated 10/100BASE-T/TX/FX 3-Port Switch, KSZ8873 Family

The KSZ8873MLL is a highly integrated 10/100BASE-T/TX 3-port switch on a chip offering the industry's smallest footprint. It is designed to give customers low port count and a cost-sensitive, power efficient, advanced power management solution. Designed to support the GREEN requirement in today's switch systems, the IC features advanced power management schemes that include hardware power down, software power down, and the energy detect mode that shuts down the transceiver when a port is idle. The device also offers the by-pass mode which enables system-level power savings. In this mode, the processor connected to the switch through the MII interface can be shut down without impacting normal switch operation. Applications suited to this solution include IP Set-Top Boxes, IP TV/IP TV POF, IP Phones/Video Phones, Analog Telephone Adapters (ATAs), Automotive Infotainment systems, industrial controls and FTTx CPE.
