25Q64FV serial flash memory

The 25Q64FV (64M-bit) Serial Flash memory provides a storage solution for systems with limited space, pins and power. The 25Q series offers flexibility and performance well beyond ordinary Serial Flash devices. They are ideal for code shadowing to RAM, executing code directly from Dual/Quad SPI (XIP) and storing voice, text and data. The device operates on a single 2.7V to 3.6V power supply with current consumption as low as 4mA active and 1µA for power-down. All devices are offered in space saving packages.

The 25Q64FV array is organized into 32,768 programmable pages of 256-bytes each. Up to 256 bytes can be programmed at a time. Pages can be erased in groups of 16 (4KB sector erase), groups of 128 (32KB block erase), groups of 256 (64KB block erase) or the entire chip (chip erase). The W25Q64FV has 2,048 erasable sectors and 128 erasable blocks respectively. The small 4KB sectors allow for greater flexibility in applications that require data and parameter storage.

AM28F256A Datasheet PDF – 256K Flash Memory – AMD

Part Number : AM28F256A

Function : 256 kilobit CMOS 12.0 volt, bulk erase flash memory with embedded algorithms

Package : DIP 32 Pin, PLCC 32 Pin Type

Manufacturers : Advanced Micro Devices


Description :

The device is a 256K Flash memory organized as 32K bytes of 8 bits each. AMD Flash memories offer the most cost-effective and reliable read/write non- volatile random access memory. The Am28F256A is packaged in 32-pin PDIP, PLCC, and TSOP versions. It is designed to be reprogrammed and erased in-system or in standard EPROM programmers. The Am28F256A is erased when shipped from the factory.
