詳細說明
The D2764A is a type of Electrically Erasable Programmable Read-Only Memory (EEPROM) chip that was commonly used in electronic devices in the 1980s. It has a capacity of 8 kilobits, which is equivalent to 1 kilobyte. The D2764A has a 28-pin Dual Inline Package (DIP) configuration, making it easy to insert into circuit boards.This chip can be electrically programmed and erased, which provides a significant benefit over traditional ROM chips that required ultraviolet light for erasing. The D2764A uses a method known as floating gate technology to store data, which allows for multiple read and write cycles.The D2764A operates on a supply voltage of 5 volts and typically has a maximum access time of around 450 nanoseconds. It has an endurance of about 10,000 program/erase cycles, making it durable for repeated use.

常見問題解答
What is D2764A?
The D2764A is a 64K bit (8K x 8) CMOS UV erasable and electrically reprogrammable memory chip designed by Intel. It is commonly used in legacy computer systems, embedded applications, and vintage electronic devices requiring non-volatile storage.
How Does D2764A Work?
The D2764A works by storing binary data in a grid of memory cells that can be selectively programmed and erased. It utilizes a combination of UV erasable and electrically reprogrammable technologies to allow for both erasure and modification of stored data. With its 64K bit capacity arranged in an 8K x 8 configuration, it provides non-volatile memory storage for various applications.
How Many Pins does D2764A have and What are the Functions of the Pinout Configuration?
The D2764A is housed in a 28-pin DIP (Dual In-line Package) package. The pinout configuration includes:
- A0-A12: Address input pins for selecting memory locations.
- DQ0-DQ7: Data input/output pins for bi-directional communication.
- CE: Chip enable for activating the memory chip.
- OE: Output enable for enabling data output.
- WE: Write enable for initiating data writes.
- VPP: Programming voltage input for electrically reprogramming the memory.
- VCC: Power supply pin.
- GND: Ground pin.
What are the Pros and Cons of D2764A?
Pros:
- Non-volatile Storage: Retains stored data even when power is removed.
- Electrically Reprogrammable: Allows for data modification without requiring UV erasure.
- Standard Package: Housed in a 28-pin DIP package for easy integration into circuit boards.
- Legacy Compatibility: Commonly used in vintage systems and legacy equipment.
Cons:
- UV Erasure Required: Erasing the memory requires exposure to ultraviolet light, which can be a specialized process.
- Limited Capacity: 64K bit capacity may be insufficient for modern high-density data storage needs.
Are There Any Equivalents/Alternatives to D2764A for Recommendation?
Equivalents to the D2764A include the M2764A from STMicroelectronics and the D2764D from Intel. Alternative options for non-volatile memory include modern EEPROM or flash memory devices with higher capacities and faster access times.
