Summit rolls out S9518E in UCSP package

Summit Microelectronics has released its S9518E DACPOT in an Ultra-ChipScale (UCSP) package, with a total footprint of 1.5-by-2.1mm.
The S9518E brings the power of Summit's S9518 nonvolatile DACPOT to space-constrained applications such cellphones, PDAs, MP3 players, and other handheld wireless equipment. It has debounced up and down switch inputs with "clickless" transition between settings. It can be set to "remember" the wiper setting when power is shut off, thereby seamlessly restoring its setting when the system is next powered up.

According to the company, the UCSP packaging provides a footprint exactly equal to the area of the chip itself, making it suitable for highly-compact handheld equipment and for all other applications where space is at a premium.

Also available lead-free as an option, the UCSP products offer one of the highest level of hermeticity with the industry-standard designation of "moisture sensitivity level 1" (MSL-1).
