The FT-817 is based on a similar circuit architecture as Yaesu's FT-857 and FT-897, so it is a compromise transceiver and incorporates its features to its low price ($670.- at its 2001 release). [3] The upgraded FT-817(N)D was launched in 2004. The difference between the two models is the addition of 60 meter band coverage in 5 fixed channels ...
The USI is a multi-purpose hardware communication module. With appropriate software support, it can be used to implement an SPI, [79] I²C [80] [81] or UART [82] interface. USART peripherals have more features than USI peripherals.
The AVR is a modified Harvard architecture machine, where program and data are stored in separate physical memory systems that appear in different address spaces, but having the ability to read data items from program memory using special instructions.
Front page of a floppy disk controller data sheet (1979) A datasheet, data sheet, or spec sheet is a document that summarizes the performance and other characteristics of a product, machine, component (e.g., an electronic component), material, subsystem (e.g., a power supply), or software in sufficient detail that allows a buyer to understand what the product is and a design engineer to ...
Mouser Electronics, Inc., is a global distributor of semiconductors and electronic components.With over $4 billion in annual revenue, Mouser is ranked as the seventh [1] largest electronic component distributor in the world.
Crystal oscillators can be manufactured for oscillation over a wide range of frequencies, from a few kilohertz up to several hundred megahertz.Many applications call for a crystal oscillator frequency conveniently related to some other desired frequency, so hundreds of standard crystal frequencies are made in large quantities and stocked by electronics distributors.
A computer module is a selection of independent electronic circuits packaged onto a circuit board to provide a basic function within a computer. [1] An example might be an inverter or flip-flop , which would require two or more transistors and a small number of additional supporting devices.
30-pin SIMM, 256 KB capacity Two 30-pin SIMM slots on an IBM PS/2 Model 50 motherboard. Standard sizes: 256 KB, 1 MB, 4 MB, 16 MB. 30-pin SIMMs have 12 address lines, which can provide a total of 24 address bits. With an 8-bit data width, this leads to an absolute maximum capacity of 16 MB for both parity and non-parity modules (the additional redundancy-bit chip usually doe
