Transputer ST20TP3CX50S SoC for DVB Satellite Systems

[Vlasta]

The ST20TP3CX50S is a full system-on-chip originally designed for DVB-S/DVB-C set-top boxes and professional IRD receivers. It marries a 32-bit ST20 RISC CPU—descended from the legendary INMOS Transputer architecture—with an on-die MPEG-2 transport-stream demultiplexer, ICAM/CSA conditional-access descrambler, smart-card I/O, DMA, and rich peripheral set. 
Because later generations moved to larger, highly-integrated parts, unused factory-fresh dice of this revision are now extremely hard to find—making it a prime collectible for silicon historians, satellite-TV buffs, and embedded-systems educators.
