KR1858VM3 - last soviet Z80 : weekend die-shot

KR1858VM3 - is the last soviet Z80. This part was manufactured on Belorussian "Transistor" fab in 1995.

While previous soviet Z80 were NMOS ones, this is 2µm CMOS. But due to "relaxed" layout (in addition to intrinsic lower logic density in CMOS) die size is even larger than 4µm NMOS variant KR1858VM1.

Die size 5050x4657 µm.

KR1858VM1 - soviet Z80 : weekend die-shot

KR1858VM1 - Z80-compatible CPU, manufactured in USSR. Die marking "U880/6" suggests that it was also designed in east Germany company VEB Mikroelektronik "Karl Marx" in Erfurt (MME). Compared to T34VM1 die size is shrunk by a factor of 1.6, reworked IO.

Also, you can compare it to MME Z80A and Zilog Z80.

Die size 3601x3409 µm.
