SAN JOSE--Advanced Micro Devices Inc. and STMicroelectronics Inc. today separately introduced new flash-memory products for a range of specialized applications.
AMD rolled out a 64-megabit, page-mode device with security features, while STMicro introduced several new additions to its range of application-specific flash memory devices.
STMicro's new devices include the M58WR128E, which are optimized for use in mobile phones and PDAs, and the M58LWxxxC family optimized for use in set-top boxes, according to the Geneva-based chip giant.
The M58WR128E is a 128-Mbit device, based on an asymmetrical block architecture. Operating with a 1.8-Volt supply, the device includes features, such as burst mode, fast read and programming operations, and block-level erasing and locking. The device, which is available with access times of 70-, 85-, and 100-ns, allows asynchronous and synchronous read operations.
The M58LW032C and M58LW064C are new 32-Mbit and 64-Mbit devices, developed in 0.15-micron technology. All the devices have advanced features such as synchronous burst read mode at up to 56-MHz and page-read mode, with access times of 110- and 25-ns, respectively.
Separately, AMD introduced the Am29PDL640G, a 64-Mbit page-mode device with security features. Designed for wireless applications and set-top boxes, the chip is a 3.0-Volt device that has 65-ns initial access times and 25-ns page access times, according to the Sunnyvale, Calif.-based company.
It features so-called Advanced Sector Protection, which provides 64-bit password protection and multiple layers of security to guard against hackers, tuners, viruses, and even erroneous code. The SecSI sector provides a large 256-byte one-time-programmable region for electronic serial numbers and other critical information.
The Am29PDL640G device is priced at $9.75 each in quantities of 10,000. Prices for STMicro's chips were not disclosed.
