21ic The package area is only 2.57mm x 3.24mm, but the audio output power is as high as 2x20W. STMicroelectronics' STA333IS is the largest single-chip digital audio system with the largest power capacity. The new product further expands the STMicroelectronics SoundTerminalTM family, integrating advanced process and chip-level packaging technologies, as well as digital audio IP modules such as ST's proprietary FFX full-featured flexible amplification technology.

STA333IS is unique in the market, because only STMicroelectronics has the technology and audio IP (intellectual property) required to integrate advanced signal processing and power circuits. The wide supply voltage range of 4.5V to 18V makes it ideal for battery-powered devices and space-constrained devices such as LCD or LED TVs, music stands and digital wireless speaker systems.
The STA333IS has exceptional sound quality, high thermal efficiency and low electromagnetic radiation. The 8.3mm2 micro package provides developers with more design freedom to develop next-generation audio products.
STMicroelectronics also introduced a microcontroller-free version, and the STA333SML eliminates the need for an external microcontroller, allowing designers to design digital amplifiers with the lowest cost.
The STA333IS and STA333SML of the 5x6 solder ball 0.5mm pitch chip scale package (CSP) have been sampling and put into mass production.
