Peripheral controller for more versatile handhelds

Cypress Semiconductor has enhanced its West Bridge™ peripheral interface for embedded devices, with a new controller IC that supports the majority of host processors, and is compatible with low-cost Multi-Level Cell (MLC) NAND-Flash memory.

The Cypress Astoria™ peripheral controller off-loads management of USB and storage from the main processor to save resources and maximise data transfer in devices such as mobile phones, digital cameras and personal media players. Astoria builds upon Cypress’s Antioch™ West Bridge IC, which more than doubles the effective file-transfer speed between a mobile phone and a host PC over High-Speed USB.

The Astoria controller goes further by featuring a configurable multimedia storage interface that ELECTRONICS FUTURE Development board DEMO9RS08KA8 is available to members of the Future Board Club. To apply for the development board, and membership of the Board Club, go to www.my-boardclub.com/manf-offers.htm This offer is free and subject to qualification. supports up to 16 NAND-Flash devices and offers the flexibility to select two SDIO devices such as Bluetooth, WiFi and GPS cards. Other storage supported includes Secure Digital High Capacity (SDHC) v. 2.0, MultiMedia Card+ (MMC+) v. 4.2, CE-ATA for HDD, and controlled-NAND variants.

Enhancements to the processor interface enables connection to a wider variety of embedded processors, and include support for asynchronous SRAM, ADMUX (Address Data Multiplexing) and SPI.
