STMicroelectronics Moves 128-Mbit NAND Flash Chip to 90nm Production Technology Geneva – STMicroelectronics announced that production of its 128-Mbit NAND Flash device – the NAND128W3A2BN6E – has been transferred to 90nm process technology. The shrink to 90nm reduces both the cost and the power consumption of the memory chip, which is widely used in cost-sensitive consumer equipment such as Digital Still Cameras, Audio Recorders, PDAs, Set-Top Boxes (STBs), Printers, and bundled Flash Cards. The NAND128 is currently the only 128-Mbit Flash memory on the market to be produced in 90nm technology. The new chip confirms ST’s commitment to continuing product development of its low density ‘Small-Page’ NAND Flash memory products, in support of customers already using the family in volume production. The NAND128W3A2BN6E is a 3V product, in a TSOP package, intended for consumer applications. Other family members – the 256-Mbit, 512-Mbit, both in 3V and in 1.8V versions – will also be moved from 120nm to 90nm technology in the coming months.

High-Voltage, 350mA, Adjustable Linear High-Brightness LED (HB LED) Driver The MAX16800 current regulator operates from a 6.5V to 40V input voltage range and delivers up to a total of 350mA to one or more strings of high-brightness LEDs. The output current of the MAX16800 is adjusted by using an external current-sense resistor in series with the LEDs. An enable input allows wide-range “pulsed” dimming. Wave-shaping circuitry reduces EMI. The differential current-sense input increases noise immunity. The MAX16800 is well suited for applications requiring high-voltage input and is able to withstand automotive load-dump events up to 40V. An on-board pass element minimizes external components while providing ±3.5% output current accuracy. Additional features include a 5V regulated output and short-circuit and thermal protection. The MAX16800 is available in a thermally enhanced, 5mm x 5mm, 16-pin TQFN package and is specified over the automotive -40°C to +125°C temperature range.
