Fujitsu Introduces New 128Mbit Mobile FCRAM
The new 128Mbit Mobile Fast Cycle RAM (FCRAM) device adopts burst mode operations complying with Common Specifications for Mobile RAM (COSMORAM) Revision 3, for use in mobile phone applications. The device is ideal for advanced applications in 3G mobile phones.
The new 128Mbit MB82DBS04314C and the MB82DBS08164C achieve maximum burst-operation frequencies of up to 108MHz with a single 1.8V supply voltage, meeting the memory requirements of next-generation mobile phone applications. The devices provide a high data transfer rate, as burst mode enables fast successive read/write operation through synchronization with the system clock.
The maximum standby current of 300 micro-A can be dramatically cut by user-configurable power-down modes such as sleep mode and partial power-down mode. In addition, the MB82DBS04314C is the first 128M Pseudo-Static RAM (PSRAM) that adopts a 32-bit address/data multiplexed bus that more than doubles the data-transfer rate compared with existing products, by extension of the data bus width. It also reduces the pin count, simplifying customer board design.
Pricing and Availability
Sample devices will be available in a monolithic package, and in chip or wafer form for embedded applications, including use in multi-chip package memory solutions. Pricing begins at $14.00 each in 10,000-unit quantities.
This announcement underlines Fujitsu's commitment to the continued development and production of high value-added Application-Specific Memory products, in response to customer requirements.
