Texas Instruments TI486SXL2 -50

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 386SX'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. Being a SX 386-class CPU this CPU has a 16-bit external bus.

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.
