25Q64FV serial flash memory
Description

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.

IEEE1394 datasheet

Description:

IEEE1394 is an interface standard for a serial bus for high-speed communications and isochronous real-time data transfer. It was developed in the late 1980s and early 1990s by Apple, who called it FireWire. The 1394 interface is comparable to USB though USB has more market share.

IEEE 1394, High Performance Serial Bus, is an electronics standard for connecting devices to your personal computer. IEEE 1394 provides a single plug-and-socket connection on which up to 63 devices can be attached with data transfer speeds up to 400 Mbps ( megabit s per second). The standard describes a serial bus or pathway between one or more peripheral devices and your computer’s microprocessor . Many peripheral devices now come equipped to meet IEEE 1394. Two popular implementations of IEEE 1394 are Apple’s FireWire and Sony’s i.LINK . IEEE 1394 implementations provide:

• A simple common plug-in serial connector on the back of your computer and on many different types of peripheral devices
• A thin serial cable rather than the thicker parallel cable you now use to your printer, for example
• A very high-speed rate of data transfer that will accommodate multimedia applications (100 and 200 megabits per second today; with much higher rates later)
• Hot-plug and plug and play capability without disrupting your computer
• The ability to chain devices together in a number of different ways without terminators or complicated set-up requirements

IEEE1394 cable

This product conforms to the IEEE 1394 Standard. With only one type of connector, you can connect several different pieces of digital peripheral equipment. The IEEE 1394 Standard connector series is capable of accommodating data rates up to 400 Mbps for serial transmission consisting of 6 position connectors, for connections of computers to peripherals, and the 4 position connectors for connections of digital AV equipment.
