USB transceiver shrinks to micro
leadframe
The USB1T11ABQ is a Universal Serial Bus transceiver in micro leadframe packaging.
The USB1T11ABQ is a Universal Serial Bus transceiver in micro leadframe packaging (MLP) MLP packaging occupies up to 84% less board space than comparable TSSOP and SOIC packages and brings USB 1.1 performance to mobile phones, digital cameras, PDAs, printers, set-top boxes and other space-constrained applications

Dual-output buffer for DDR SDRAM modules
Fairchild Semiconductor has introduced a dual-output registered buffer for 184-pin, 2.5V PC200/PC266, 72bit-wide registered double data rate (DDR) SDRAM modules.
Bus hold makes logic more predictable
Fairchild Semiconductor has made a number of additions to its LCX family, the logic industry standard for 3.3V applications.
Fairchild's USB1T11ABQ transceiver interfaces 5.0 or 3.3V standard or programmable logic to the USB physical layer, and supports both 12Mbit/s full speed and 1.5Mbit/s low-speed data transmission rates.
I/O signal compatibility with the USB Implementers Forum's VHDL "Serial interface engine" specification helps engineers to easily design, modify and update USB 1.1 applications using off-the-shelf logic.
Using the JEDEC MO-220 (3mm2) form factor, the MLP package eliminates coplanarity problems caused by flexing leads, as sometimes occurs with TSSOP and SOIC package designs.
Other MLP-derived design benefits include lower component height of 1.0mm for space-restricted portable designs, lower thermal resistance due to the component's centre DAP that connects directly to the die and PC board, and the device's 0.5mm pin-to-pin pitch that supports current manufacturability standards.
"Fairchild's new USB transceiver in ultra small MLP packaging provides the space savings needed for designers of hand-held devices to add USB functionality to their designs", says Seth Prentice, Product Manager for USB and Analogue Switch Products.
