AMD Élan

December 15, 2023

AMD Élan is a family of 32-Bit embedded SoCs marketed by AMD based on x86 microprocessors. All of these products have been backed with a long-term supply guarantee to meet the needs of embedded processors. However, when AMD acquired the Geode division from National Semiconductor in August 2003, the product was suddenly discontinued. The Élan processors have certainly provided some momentum in the embedded world.[1][2]

SC3xx family edit

The SC300 and SC310 combines a 32-Bit, x86 compatible, low-voltage 25 MHz or 33 MHz Am386SX CPU with memory controller, PC/AT peripheral controllers, real-time clock, PLL clock generators and ISA bus interface. SC300 integrates in addition two PCMCIA 2.1 slots and a CGA-compatible LCD controller. Power consumption at 33 MHz was only 600 mW including CPU, memory controller and peripherals. In suspend mode consumption reduces to 0,17 mW.[3][4][5][2] The low budget 9,7" laptop Brother GeoBook NB60 uses a SC300[6]

SC4xx family edit

The SC400 and SC410 combines a 32-Bit, x86 compatible, low-voltage 33 MHz, 66 MHz or 100 MHz Am486 CPU with memory controller, PC/AT peripheral controllers, real-time clock, PLL clock generators, VESA Local Bus and ISA bus interface. SC400 integrates in addition two PCMCIA 2.1 slots and a 4-bit color Super-twisted nematic display (STN) LCD controller.[7][5] The C64 "Web.it" Internet Computer uses a SC400 with 16 MB of RAM, a 3.5" floppy disk drive, 56k-modem and PCMCIA. [8] The AirPort Base Station uses a SC410,[9] the Nokia 9000 Communicator a SC450.[10] AMD announced the SC400 on October 15, 1996.[11]

SC5xx family edit

The SC520 combines a 32 bit, x86 compatible, low-voltage 100 MHz or 133 MHz Am5x86 CPU with memory controller supporting SDRAM, PC/AT peripheral controllers, real-time clock and PCI bus. ISA and PCMCIA were no longer supported.[12][5] AMD announced the SC520 on August 25, 1999.[13]
