World's smallest claim for Flash cards
Hitachi reckons its RS-MMC reduced-size MultiMediaCards are the world's smallest Flash cards.
Hitachi reckons its RS-MMC reduced-size MultiMediaCards are the world's smallest Flash cards Measuring just 18 x 24 x 1.4mm, the 16, 32 and 64Mbyte cards offer the same functionality as current MultiMediaCards but are approximately half the size and weight

MCUs have a huge 32Kbyte of RAM on-chip
Hitachi Europe has announced the immediate availability of a new series of 16bit microcontrollers featuring 32Kbyte on-chip RAM - the first in the industry to do so.
Most integrated GSM RF transceiver so far
Hitachi has launched its most integrated GSM RF transceiver solution to date.
The cards are suitable for data storage in small mobile devices, including next-generation mobile phones and PDAs, and portable imaging products such as digital cameras.
The new cards are the first commercial models of the RS-MMC standard, which was approved by the MultiMediaCard Association (MMCA) and announced on 11th November 2002.
The reduced size of the cards will enable the development of small, high-density wearable devices.
The RS-MMCs can be used as ultra-compact built-in memory modules that can be easily added or replaced, as well as removable media.
The RS-MMCs employ Hitachi's multi-chip module mounting technology and incorporate the same multi level cell AND-type Flash memories and controller as the HB28xxxxMM2 high-speed MultiMediaCard series.
The new devices are compatible with current MultiMediaCards and have identical functions, pin-count and thickness.
An adapter (mechanical expander) can be used to make the package size equal to that of a standard-size MultiMediaCard, enabling RS-MMCs to be used in products designed for MultiMediaCard use.
The new cards offer a fast write speed of 1.0Mbyte/s (this does not including processing time in the player) and have low power consumption, with a typical read current of 28mA and typical write current of 33mA.
This helps to extend the battery life of mobile devices.
The devices use the same support tools as previous MultiMediaCards.
Driver and file manager software, hardware such as an H8S microcontroller-based development platform, and analytical tools such as a dedicated MultiMediaCard protocol analyser, are available from third-party suppliers.
