Q: What are the key features of the Micron Technology PC28F256P30TFE?
A: The Micron Technology PC28F256P30TFE is a 256 Mbit NOR flash memory device designed for nonvolatile data storage. It uses multi-level cell (MLC) technology and supports the Common Flash Interface (CFI), which helps compatible systems identify the memory's configuration. Key specifications include a 52 MHz interface frequency, a 100 ns access time, and a 64-ball EasyBGA package measuring approximately 10 × 13 mm. Its nonvolatile design retains stored information when power is removed, making it suitable for firmware and other essential system data.
Q: What is the PC28F256P30TFE used for?
A: The PC28F256P30TFE is used to store firmware, boot code, configuration settings, and other data that must remain available when a system is powered off. Typical applications include embedded computing equipment, industrial control systems, communication devices, and electronic products that require reliable program storage. Its NOR flash architecture supports code storage and random access, while CFI support can simplify memory identification and configuration in compatible systems.
Q: Are there alternative manufacturers and part numbers for the PC28F256P30TFE?
A: Potential alternatives include the Infineon S29WS256P and related 256 Mbit parallel NOR flash devices from other manufacturers. However, these parts may differ in memory organization, command sets, supply voltage, timing, sector layout, and package configuration. The PC28F256P30TFE is an older device and is listed as obsolete by distributors, so replacement selection requires particular care. Confirm pin compatibility, electrical specifications, memory commands, and firmware requirements before using an alternative.
