Texas Instruments TI486SXL2 -50

Pentium Unfinished | MII 333GP/66x4 View next object

A new-old-stock 'FOR OEM USE ONLY' processor from Texas Instruments. It fits in a 386 socket and is able to do clock-doubling like the 486DX2. This means it will run at 50MHz on a 25MHz motherboard.

Because this CPU has 8KB L1-cache it should perform quite well. Regular 386's don't have L1-cache at all and most budget 486 CPU's that fit in a 386 socket only have 1KB L1-cache.

Unfortunately this CPU doesn't have a date code so I can't really pin-point when it's made. The code FC2-63ANT9T is a batch code that is not unique to this particular CPU; all the CPU's from this batch have that same number. Texas Instruments released the TI486SXLC-33, TI486SXL-40, TI486SXLC2-50, TI486SXL2-50 for respectively, US$79, US$89, US$110 and US$149, in quantities of 1000 units.

You do know that Ti486SXL2 has nothing to do with 386SX. It is a 386DX replacement and performs around 30% faster then the 386DX at the same clock. Doubleclocking has to be enabled via small program. Otherwise you can run it as 1X up to 50MHz if you overclock the 386 motherboard.

Thanks for the heads-up. I've corrected the text. It is indeed a DX-replacement .
