AM27C256-55DC Product details
GENERAL DESCRIPTION
The Am27C256 is a 256K-bit ultraviolet erasable programmable read-only memory. It is organized as 32K words by 8 bits per word, operates from a single +5 V supply, has a static standby mode, and features fast single address location programming. Products are available in windowed ceramic DIP packages as well as plastic one time programmable (OTP) PDIP, TSOP, and PLCC packages.
Typically, any byte can be accessed in less than 55 ns, allowing operation with high-performance microprocessors without any WAIT states. The Am27C256 offers separate Output Enable (OE) and Chip Enable (CE) controls, thus eliminating bus contention in a multiple bus microprocessor system.
AMD’s CMOS process technology provides high speed, low power, and high noise immunity. Typical power consumption is only 80 mW in active mode, and 100 µW in standby mode.
All signals are TTL levels, including programming signals. Bit locations may be programmed singly, in blocks, or at random. The Am27C256 supports AMD’s Flashrite programming algorithm (100 µs pulses) resulting in typical programming time of 4 seconds.

Electronic components are the basic building blocks of electronic circuits and are used to construct
various circuits that enable electronic products to perform various functions. The following are common
electronic components and their main functions:
1. Capacitor: used for storing charge, smoothing voltage, filtering, delaying, etc.
2. Resistor: used for limiting current, changing voltage, dividing voltage, regulating current, etc.
3. Diode: used for rectification, voltage stabilization, switching, etc.
4. Transistors such as thyristors and triodes: used for signal amplification, current control, switching, etc.
5. Integrated circuits (ICs): integrate multiple electronic components to achieve complex circuit functions.
6. Sensors: convert various physical quantities into electrical signals, such as temperature, humidity, light intensity, pressure, etc.
Electronic components are widely used in various electronic products such as computers, mobile phones,
