Geode CS5535 or CS5536 companion chip Geode SCxx00 Series Developed by National Tel Aviv (NSTA) based on IP from Longmont and other sources. Applications: The SC3200 was used in the Tatung TWN-5213 CU. AMD Geode In 2002, AMD introduced the Geode GX series, which was a re-branding of the National Semiconductor GX2. This was quickly followed by the Geode LX, running up to 667 MHz. LX brought many improvements, such as higher speed DDR, a re-designed instruction pipe, and a more powerful display controller. The upgrade from the CS5535 I/O Companion to the CS5536 brought higher speed USB. Geode GX and LX processors are typically found in devices such as thin clients and industrial control systems. However, they have come under competitive pressure from VIA on the x86 side, and ARM processors from various vendors taking much of the low-end business. Because of the relative performance, albeit higher PPW, of the GX and LX core design, AMD introduced the Geode NX, which is an embedded version of the Athlon processor, K7. Geode NX uses the Thoroughbred core and is quite similar to the Athlon XP-M that use this core. The Geode NX includes 256 KB of level 2 cache, and
