AMD Boosts Wireless Security with New Memory Chip Am29PDL640G


AMD has introduced the Am29PDL640G, a 64 Mbit 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 superior combination of high-performance, long battery life, and sophisticated security.

“This product provides a fortress on a circuit board, helping protect the integrity of the wireless telephone or television network,” said Ian Williams, vice president of customer operations for AMD’s Memory Group. “Customers can count on multiple layers of protection designed to prevent would-be signal thieves from fraudulently billing calls to other users’ accounts or pirating television programming.”

Unlike competing wireless Flash memory products, the Am29PDL640G device can improve network security and the user experience while also lengthening battery life.

“Mobile consumers – ‘connected’ consumers – would rather not have to wait. High-throughput page-mode devices like the Am29PDL640G help minimize phone application load times,” said Williams. “AMD’s Simultaneous Read/Write architecture means the phone can still function while downloading applications, ringers, games, and pictures, so consumers can enjoy rich and responsive interfaces in demanding operating environments, such as 2.5G and 3G phones. Of course, high-performance isn’t enough for battery-powered mobile devices. The Am29PDL640G device features a low-power design to help users to talk, e-mail, stay organized, and play longer. Essentially, we take less power from your battery and give more power to you.”

Features and Packaging

For designers who need to quickly deliver rich user interfaces and improve their wireless network’s security, AMD’s Am29PDL640G is a 3.0-volt page-mode Flash memory device that offers 1.8 V and 3.0 V input and output voltage options, hardware-based simultaneous read/write, and low standby power. This 64 Mbit device includes the following features and specifications:

– 65 ns initial access times and 25 ns page access times provide up to 80 MB/s intra-page read throughput and 66 MB/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 competing 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 that only authorized users change manufacturer-selectable areas of the Flash memory. – – Persistent sector protection mode combines two additional protection mechanisms to help guard against viruses and erroneous code.
– 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. The Am29PDL640G device uses a 3.0 V power supply and can interface with components that use I/O and control pin voltages from the 1.8 V range to the 3.0 V range.
– Standby current as low as 1 µA lengthens battery life during periods of inactivity.
– A pin-compatible upgrade path to 128 Mb, .13 µm Flash provides migration flexibility.
– Multi-Chip Package options allow packaging with SRAM and pSRAM.
– Design targets of one million write/erase cycles, 20 years’ data retention at 125 °C help customers to design with confidence.
