CHIPMAKER Toshiba has announced an audio codec chip for mobile phones with improved background noise cancellation technology.

Toshiba's semiconductor business has been busy producing NAND flash memory chips found in smartphones and tablets, but the firm has been developing other chips using its proprietary technology for the rapidly growing mobile device market. Now the firm has announced a new audio codec with background noise cancellation technology and a chip structured array that it claims saves prototyping time.

Toshiba's TC94B24WBG single chip audio codec eliminates the need for separate speaker, headphone and line-out amplifiers and has integrated audio post-processing support along with a programmable digital signal processor. The firm said that the chip supports single microphone noise and echo cancellation during phone calls and equaliser and dynamic range control during audio playback.

Aside from its new audio codec chip, Toshiba also announced a new structured array that it claims requires only a few layers of metal masks to customise for specific applications. The firm said the array, which is licensed from Baysand, can be used to create system on chip (SoC) designs and is compatible with field programmable gate arrays (FPGAs) by using register transfer level (RTL) design data.

Toshiba said its structured array, which can hold a maximum of 30 million gates, is fabbed on a mature, low cost 65nm process node. The firm said its structured array will be available from April while the TC94B24WBG audio codec is sampling now and scheduled for production in March. µ
