The V70 (μPD70632) improved on the V60 by increasing the external buses to 32 bits, equal to the internal buses.
It was also manufactured in 1.5 μm with a two-metal layer process.
Its 14.35 × 14.24 mm² die had 385,000 transistors and was packaged in a 132-pin ceramic PGA.
Its MMU had support for demand paging.
Its floating-point unit was IEEE 754 compliant.
The 20 MHz version attained a peak performance of 6.6 MIPS and was priced, at launch in August 1987, at ¥100,000 ($719.42).
The initial production capacity was 20,000 units per month.
A later report describes it as fabricated in 1.2-micrometer CMOS on a 12.23 × 12.32 mm² die.
The V70 had a two-cycle non-pipeline (T1-T2) external bus system, whereas that of the V60 operated at 3 or 4 cycles (T1-T3/T4).
Of course, the internal units were pipelined.

The V70 was used by Sega in its System Multi 32 and by Jaleco in its Mega System 32. (
See the photo of the V70 mounted on the latter system's printed circuit board.)

JAXA embedded its variant of the V70, with the I-TRON RX616 operating system, in the Guidance Control Computer of the H‑IIA carrier rockets, in satellites such as the Akatsuki (Venus Climate Orbiter), and the Kibo International Space Station (ISS) module.
The H‑IIA launch vehicles were deployed domestically, in Japan, although their payloads included satellites from foreign countries.
As described in JAXA's LSI (MPU/ASIC) roadmap, this V70 variant is designated "32bit MPU (H32/V70)", whose development, probably including the testing (QT) phase, was "from the middle of 1980s to early 1990s".
This variant was used until its replacement, in 2013, by the HR5000 64-bit, 25MHz microprocessor, which is based on the MIPS64-5Kf architecture, fabricated by HIREC, whose development was completed around 2011.

"Space Environment Data Acquisition" for the V70 was done at the Kibo-ISS exposed facility.
