Datecode 827.Die size 1358x1104 µm.Read more → January 8, 2022 RCA CD4000BE - CMOS standard logic : weekend die-shotCD4000 contains 2x 3-input NOR gate + 1x inverter gate. Die size 1722x1394 µm. Datecode 749. January 2, 2022 Infineon BFP450 - highly linear low noise BJT, 24Ghz fT : weekend die-shotI like that it is complex for a BJT, yet one can see everything without de-layering. You can compare it to BC858C (fT 250 MHz), BFP540 (fT 30 GHz) and BFR740 (fT 42 GHz). Apparently complexity explodes beyond 24Ghz. Die size 526x456 µm.

November 1, 2021 Ti TMS0119 - single-chip calculator (1971) : weekend die-shotTexas Instruments TMS0119 is part of TMS100-series of integrated single-chip calculators. Ti was first in the world (1971) to achieve this level of integration. Originally used in TI-2500 calculator. It is made using 10 um metal gate PMOS process (metal width = 10 um, metal spacing = 10 um, diffusion width = 10 um, diffusion spacing = 10 um). You can read much more about Texas Instruments calculators & their microchips at http://www.datamath.org/, which is a result of countless years of Joerg Woerner's dedication. Die size 5874x5800 µm. October 11, 2021 Toshiba TC74HC181P - 4-bit ALU : weekend die-shotTogether with 74*182, Toshiba TC74HC181P could be used to build custom discrete CPU. Die size 2730x2722 µm. Datecode 8813H. 1↦23..35
