National Semiconductor Geode SC3200 system on a chip
National Semiconductor Geode SC3200 system-on-a-chip, marketed as "WebPAD-on-a-chip", was announced in September 2000 along with other members from SCx200 family: Geode SC1200 and Geode SC2200. The SoC parts, and a software development platform for the SC3200, became available in March 22, 2001. The system-on-a-chip was used in a number of Personal Access Devices (PAD) and internet appliances, including conceptual Geode Origami Portable Mobile Communicator, unveiled in November 2001, Philips E-Tablet, presented at CeBIT 2002 show, and NEC Smart Display SD10, which was announced in January 2003.
The SC3200 SoC integrates CPU core, as well as many system components and peripherals such as 64-bit memory controller, 2D graphics accelerator and display controller, power-management logic, and several I/O and bus interfaces: USB, IDE, PCI, LPC, ACCESS.bus, and serial and parallel ports. The CPU in the SC3200 is based on Geode GX1 core, which incorporates Floating Point Unit, 16 KB level 1 cache, and, besides support for x86 instruction set, adds MMX instructions. Video controller on the SC3200 supports only TFT interface.
