IBM 386SLC

From Wikipedia, the free encyclopedia

The 386SLC was an Intel-licensed version of the 386SX, developed and manufactured by IBM in 1991. It included power-management capabilities and an 8KB internal cache, which caused it to run as fast as 386DX processors of the same speed, which were considerably more expensive. Known inside IBM as "Super Little Chip" for its initials, it was used in IBM PS/2 35, 40 56 Series and in IBM PS/ValuePoint, but never gained much market share. It was also marketed as an optional upgrade for 8086-equipped IBM PS/2 25 Series computers.

[edit] Design and Technology

Built with complementary metal oxide semiconductor (CMOS) technology, the IBM 386SLC had a 161-square millimeter die. It was available with clock speeds of 16, 20, and 25 MHz. The 25Mhz model produced only 2.5 watts of dissipated power, making it specially well suited for laptops and other portable devices.

[edit] IBM 486SLC

Is an improved version of the IBM 386SLC, based on the Intel core. IBM 486SLC had a 1.349 mln. transistors, 69mm² die, 16Kb of L1 cache. Manufactured in 1992. 100-pin PQFP, 33MHz FSB.

[edit] Blue Lightning

In July, 1993 IBM produced a full 32-bit 486BL/4 75MHz, 486BLX2, 486BLX3 (BL - Blue Lightning). It was an improved SLC version with 1.4 mln transistors on the 82mm² die, 0.8µm CMOS. Package is 132-pin QFP. Were sold by IBM only.
