Cyrix Cx486SLC/e-V25MP


Cx486SLC/e-V25MP DF7339E	(C)(M)1992 Cyrix USA

This CPU has a 486 instruction set and a 386 pinout. SLC/e stands for low power (SMM: System Management Mode) version of a Cx486SLC.

Comment by Paul Hoffman (paulhoffman18[at]gmail.com):

the Cx486SLC/e was packaged in a unique package named `MQUAD` developed and produced by Olin Interconnect Technologies. The package had a black-anodized lid and base that was attached to the leadframe with an adhesive seal. The characteristic sign of the package was the circular pattern in the center of the lid (as in the picture). This was actually a small anodized aluminum disk that was used to seal a vent hole in the package lid (venting was required during the cure of the adhesive seal). The MQUAD package offered superior thermal performance due to its aluminum body - but was relatively short-lived as it was a non-standard package technology.

Comment by VMUNIX (andres_leitner[at]yahoo.com.ar):

I'm wondering what "fastcache" stands for ? and why is it only 2Kb instead of 8Kb

The Cyrix 486S is a i486SX compatible processor with 2kB write back cache. All the other cpus on the market at this time had no write back cache. The 486S also had a special signal (write burst), the usage of this depends on the motherboard design. These both things brought cyrix a speed up of around 6% (to a i486SX).
