Renesas introduces Dual Voltage MMC and Reduced Size Dual Voltage MMC cards

Renesas Technology introduced the Dual Voltage MMC cards operating at 1.8V or 3V (vs. the standard 3V/5V) as well as the Reduced Size Dual Voltage MMC cards (RS-DV-MMC). The latter are designed for mobile handsets, digital cameras, digital televisions, etc. The latter are approximately twice smaller than standard MMC cards (24.0x32.0x1.4) — 24.0x18.0x1.4 μμ. 32MB models of both types will be introduced in Japan in March 2004, with 64MB and 128MB cards arriving in May 2004.

As for the higher-capacity cards, having already developed 256MB and 512MB solutions for 3.3V voltage, Renesas currently works on 1GB cards. The next product to be announced is a 4GB MMC card. 256MB solutions will be sampling in March and 512MB cards – in June 2004.

Speaking of the complete MMC series offered by Renesas, it also includes standard 3V MultiMediaCards with 16/32/64/128 MB capacities and 32/64MB RS-MMC.

Dual Voltage MMC and RS-DV-MMC solutions are made using 0.13µm process and feature Renesas´s proprietary controllers. By the way, despite the lower voltage, Renesas 1.8V MMC cards provide 1.8MB/s throughput.
