Product Overview
Intel's Smart 3, Smart 5 and SmartVoltage FlashFile™ memory components offer the lowest cost per bit flash solutions for high density applications. The FlashFile family provides density upgrades with full pinout and package compatibility for 4-, 8- and 16-Mbit densities. These components feature SmartVoltage technology which enables fast factory programming and low voltage designs. They provide a high-density, low-cost nonvolatile read/write storage solution that is ideal for both code and data storage.
Product Description
The 4-, 8- and 16-Mbit Smart 3, Smart 5 and SmartVoltage FlashFile memory component families are symmetrically blocked, byte-wide flash devices. They have 64-Kbyte erasable blocks, extended cycling, high read performance write automation, program/erase suspend capability and individual block locking. Combined, these features provide a highly flexible component that is suitable for a wide range of applications.
SmartVoltage technology on these new byte-wide FlashFile memory components offer voltages factory optimized for different system requirements at a lower cost to the customer. Smart 5 components are specifically optimized for 5V systems and support 5V Vcc and 5V or 12V Vpp. While Smart 3 components operate at 2.7V (read-only) or 3.3V Vcc and 3.3V or 12V Vpp. For ultimate voltage flexibility, SmartVoltage flash memories support 2.7V (read-only), 3.3V or 5V Vcc and 3.3V, 5V or 12V Vpp. Fast programming with 12V Vpp option, supported on all byte-wide components, lowers manufacturing cost by improving throughput time. The 3.3V and 5V Vpp enables simple, single-voltage, lower power designs.
New in the command set of this byte-wide FlashFile memory family are enhanced program/erase suspend capabilities. The Smart 3, Smart 5 and SmartVoltage FlashFile memory families are the first flash memory components to offer program-suspend-to-read with a known maximum latency, enabling rigorous real-world solutions. Additionally, the suspend commands allow two system processes to multiplex. For example, a flash audio recorder can "write while erasing." This emulates tape recorders which record over previous data. Based on these enhanced features, new aplications for flash memory will emerge.
The byte-wide Smart 3, Smart 5 and SmartVoltage FlashFile memory families are the ideal choice for high-density code and data storage applications. For high-density data acquisition applications, these products offer a cost-effective and reliable alternative to SRAM + battery. For secure code storage applications, such as networking, where code is either directly executed out of flash or downloaded to DRAM, the byte wide FlashFile memory families offer three levels of code protection: absolute protection with Vpp=GND, selective hardware block locking, and flexible software block locking. These alternatives give the designer ultimate control of code security needs.
The byte-wide Smart 3, Smart 5, and SmartVoltage FlashFile memory families are manufactured on Intel's 0.4-micron ETOX™ V process technology. They are available in 40-lead TSOP and 44-lead PSOP packages.
