National Semi Launches LP3933/35/36/38/41/45/46 ASICs

National Semiconductor Corp. (Santa Clara, CA) introduced seven mixed-signal power and lighting management application-specific integrated circuits (ASICs) for the hand-held market. The new products, the LP3933, LP3935, LP3936, LP3938, LP3941, LP3945 and LP3946, are suitable for voice-centric and multimedia-centric mobile phones and other battery-operated portable devices such as personal digital assistants.

The programmable analog power management systems (the LP3935, LP3938, LP3941, LP3945 and LP3946) include fully independent and programmable lithium-ion and nickel-metal hydride battery charging functions, high-efficiency linear regulators, system startup and control, and serial interfaces and display LED drivers all in compact, thermally efficient, leadless leadframe (LLP) packages.

The new mixed-signal ASIC devices will first be offered in small LLP and laminate chip-scale packages (CSP), and will then move to Microfil™ packaging that will allow size reductions ranging from 4 to 7 times smaller than conventional packaging. The Microfil package will be made available during the summer of 2003, the packages of 64 pins and below will become available during the third quarter of 2003, and higher pin counts will be made available in the fourth quarter.

The LP3935, LP3936, LP3938, LP3941 and LP3945 are available for sampling now. The LP3933 and LP3946 will be sampling during the second quarter of 2003. The LP3935 and LP3945 will release to production during the second quarter of 2003. The LP3933, LP3936, LP3938, LP3941 and LP3946 will release to production during the third quarter of 2003.

The LP3933 is priced at $1.30 each; the LP3936 is priced at $1.20 each; the LP3935 is priced at $1.75 each; the LP3938 is priced at $1.90 each; the LP3941 is priced at $2.25 each; and the LP3945 and LP3946 are priced at $0.98 each and $0.90 each, respectively, all in 500,000-unit quantities.
