TMP76xxx/MH6xxx

MH6xxx are a microprocessor series produced for Mitsubishi Electric Corp. by Toshiba Corp. by a yet to be determined division. They are used exclusively? for automotive applications in ECUs (PCBs and IC packaging marked Mitsubishi) for multiple makes in models including Mitsubishi's own Mitsubishi Motors Corp., Mitsubishi Motors North America Corp. (Diamond-Star Motors), as well as Mazda, Hyundai, Suzuki, and others.

Production

Technology

• CMOS

From the microscope die images I compiled of TMP76C75T there can be seen in two corners of the die, test transistors. They are marked "S-G-N" and "S-G-P", Source-Gate-N-type and Source-Gate-P-type. From that, and production technology in use at the time based on their date codes (~1990-1995), these were produced with CMOS technology.

Process

• ~500-800nm

Based on production technology in use at the time, based on date codes ~90-95, sources point to the process as being ~500-800nm.

Fab

• Possibly Tohoku Semiconductor(TSC)/Sendai Fab

Though there is no evidence of this, only the coincidence of the plant's opening (~1987), Toshiba's involvement, mentions of microprocessor production and automotive specialization. When Motorola moved production from TSC to Austin, Texas, a document shows that the production on a TMP line was affected.
