SEMICONWELL
Integrated Passive Networks
| Keyboard and mouse chip takes protection onboard The SWKBM-16QS is billed as the first RoHS-compliant single-chip keyboard and mouse device to incorporate ESD protection and EMI/RFI filtering. Semiconwell has developed the SWKBM-16QS, the first RoHS-compliant single-chip keyboard and mouse device to incorporate ESD protection and EMI/RFI filtering. The SWKBM-16QS is designed specifically for the ruggedised and embedded industrial computer market. The Semiconwell single chip solution is cost effective, and saves board space by eliminating the use of five capacitors, four pull-up resistors and 10 diodes. It increases reliability, reduces weight and is environmentally friendly being lead free. Samples are available now. The SWKBM-16QS is priced at US $0.61 in 100,000-unit quantities and $1.147 in 5000-unit quantities. Production lead time is 4-6 weeks ARO. Semiconwell has signed Passelec to market and distribute its integrated passive networks products in France Thin film expertise supports French sales Semiconwell has signed Passelec to market and distribute its integrated passive networks products in France. Semiconwell was attracted to Passelec because of its experience in thin film passive components market, sales, marketing and technical resources. Passelec will be servicing existing accounts, and will concentrate on winning new designs in automotive, instrumentation, military, medical and audio applications. Synerdyne has been signed to market and distribute Semiconwell integrated passive networks products to Japan. Semiconwell was attracted to Synerdyne because of its experience in thin film passive components market, technical resources and high levels of market penetration in Japan. Synerdyne had been the local distributor for California Microdevices for many years, but that company's change of focus and marketing strategy had left a market void in Japan to be filled by Semiconwell. As well as servicing existing accounts, Synerdyne will concentrate on winning new designs in automotive, instrumentation, military, medical and audio applications. Semiconwell has developed a new line of 9- and 27-channel surface mount LVD resistive networks designed for high-performance active termination of SCSI networks compliant with SPI-2 (Ultra2), SPI-3 (Ultra3) and beyond. Manufactured on ceramic substrates, these devices virtually eliminate channel capacitance and lead inductance, the primary cause of reduced system performance. The LVD SCSI is packaged in a moulded lead frame package (MLP) which offers greater reliability than the exposed resistors of a BGA version. The MLP package is also smaller than BGA, does not require special assembly equipment and is easy to rework and repair at board level. A typical existing BGA version occupies 90,000mil2 of PCB area for every nine channels. The new 20-pin nine-channel device, the SWRSCSI-20ML5, occupies only 25,200mil2 of board area. And the 27-channel, 56-pin SWRSCSI-56ML13 uses only 102,400mil2 of board, compared with 270,000mil2 necessary for three BGA devices. Semiconwell's integrated isolated zero-ohms jumper array networks can be used in a wide range of applications including as PC board crossovers or permanent jumpers, or to program, customise or alter the functionality of a PC board. Thanks to a very low capacitance between jumpers, these devices can be used also on high-speed data lines. The R0J series solution saves board space, improves PC board performance and reduces assembly cost on passive components. SWR0J devices are available in DIP, SOIC, QSOP, TSSOP packages. SWR0J-3ST is a three-way all-shorted variation of zero-ohm jumpers packaged in a 3-pin SOT23 with two zero-ohms jumpers per package. |
