Flash memory for wireless market

Supplier News

AMD has introduced the Am29PDL640G, a 64Mb page-mode Flash memory device with sophisticated security features, to frustrate would-be hackers and signal thieves with multiple security modes including 64-bit password protection.

Designed for wireless applications such as mobile phones and other applications including television set-top boxes, the Flash memory device delivers a combination of high-performance, long battery life, and sophisticated security.

The Am29PDL640G device can improve network security and the user experience while also lengthening battery life.

For designers who need to quickly deliver user interfaces and improve their wireless network's security, AMD's Am29PDL640G is a 3V page-mode Flash memory device that offers 1.8V and 3V input and output voltage options, hardware-based simultaneous read/write, and low standby power.

This device includes the following features and specifications:

* 65ns initial access times and 25ns page access times provide up to 80MB/s intra-page read throughput and 66MB/s sustained sequential read throughput.

* Eight-word page-mode provides 10% more throughput than competing four-word page-mode Flash and 40% more throughput than non-page asynchronous Flash.

* Four-bank simultaneous read/write architecture provides high-performance flexibility and less-complicated coding.

* Advanced Sector Protection security provides multiple layers of security to guard against hackers, tuners, viruses, and even erroneous code. 64-bit password protection mode can help ensure only authorised users change manufacturer-selectable areas of the Flash memory.

* The SecSI sector provides a large 256 byte one-time-programmable region for electronic serial numbers and other critical information.

* Space-saving FBGA packaging discourages hardware hackers by limiting access to Flash pins while also enabling thinner and smaller products.

* Enhanced versatile I/O technology increases design flexibility by enabling separate power supply and I/O voltage levels for the Flash memory device.
