Samsung is upping performance in higher-end mobile phones and PDAs through the release of an ARM9-based CPU that can scale up to 533 MHz.
Developed in a 0.13-micron process, the S3C2440 combines an ARM920T core with 16 kbyte of both I and D cache, a four-channel DMA controller, an LCD DMA/controller, a camera interface, a JTAG interface and a USB controller.
The chip also offers a host of interfaces, including: a NAND flash interface, an SD/MultiMediaCard/SDIO interface and I2C interface, an I2S interface for stereo outputs along with an analog-to-digital interface for linking in touch-screen interfaces.
The S3C2440 supports Windows CE, Palm, Symbian and Linux operating systems. It also delivers support for both TFT and STN LCD displays.
The mobile processor will be available in 300-, 400-, and 533- MHz speeds and will operate from a 0.13-V core supply. When running from this voltage, Samsung expects the chip to consume approximately 0.8-mW/MHz power.
The processor is supplied in a 289-ball BGA package and will enter volume production in the fourth quarter of 2003.
