Freescale Semiconductor has launched the i.MX233 application processor that integrates mixed signal technology to lower costs and streamline product design in a broad range of embedded and consumer products.

The i.MX233 processor incorporates analog and mixed-signal technology acquired via Freescale's 2008 acquisition of SigmaTel. This key mixed-signal technology includes integrated power management, analog audio and A/D channels.

With an ARM9 core operating up to 454MHz, the i.MX233 processor is designed to maximize performance and extend battery life in many applications such as eBooks, portable media players and other mobile consumer electronics applications requiring graphical user displays. Additional applications include VoIP handsets, smart remotes, home appliances, audio peripherals/accessories and simple human machine interface systems for industrial applications.

The integrated power management system enables efficient MIPS per application while clock gating and multiple low power modes optimize low power performance. The processor also combines an LCD controller with touchscreen and display processing, connectivity ports such as USB 2.0 with PHY, SDIO, standard UARTs, I?C and SPI ports, analog features, including audio codecs and ADCs, and an external memory interface, as well as support for external NAND with hardware error correction capabilities for improved reliability.

An image processing unit supporting 24bit VGA displays is included to enable rich user interfaces. An on-chip SDIO controller eliminates the need for an external component and provides expansion capabilities to memory cards and wireless connectivity standards such as Wi-Fi and Bluetooth wireless technology.

Freescale's i.MX233 processors are offered for both consumer and industrial operating ranges.

Suggested resale pricing of the i.MX233 processors in 10,000-unit quantities ranges from $5.11 to $5.88 in the 128-pin LQFP package and $6.03 to $6.79 in the 169-pin BGA package.

Production quantities of Freescale's i.MX233 processors, along with development boards and software, will be available in October.
