FAQs

What is AT28C64B-15SU?

The AT28C64B-15SU is a 64K (8K x 8) Parallel EEPROM (Electrically Erasable Programmable Read-Only Memory) designed by Microchip Technology. It is ideal for applications requiring non-volatile data storage, such as microcontroller programming, configuration storage, and data logging.

How Does AT28C64B-15SU Work?

The AT28C64B-15SU operates as a non-volatile memory device capable of storing digital data without the need for a continuous power source. It utilizes parallel communication for both data input and output, allowing for efficient interfacing with external microcontrollers or data processors. The EEPROM can be electronically erased and reprogrammed, providing flexibility for data updates and revisions.

How Many Pins does AT28C64B-15SU have and What are the Functions of the Pinout Configuration?

The AT28C64B-15SU is housed in a 28-lead SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:

A0 - A13: Address inputs for selecting memory locations.
IO0 - IO7: Bidirectional data input/output pins.
CE: Chip enable for activating the device.
OE: Output enable for enabling data output.
WE: Write enable for initiating write operations.
VCC: Power supply pin.
GND: Ground pin.

What are the Pros and Cons of AT28C64B-15SU?

Pros:

Non-Volatile Storage: Retains data even without power, suitable for data backup and storage.
Parallel Interface: Allows for high-speed data transfer and efficient interfacing with microcontrollers.
Flexible Write Operations: Supports electronic erasure and reprogramming for data updates.
Wide Voltage Range: Can operate within a wide supply voltage range, providing flexibility in system design.

Cons:

Programming Complexity: Requires careful handling and specific control signals for write operations.
Limited Endurance: May have a limited number of erase/write cycles compared to other non-volatile memory technologies.
Package Size: The 28-lead SOIC package may require more board space compared to smaller form factors.

Are There Any Equivalents/Alternatives to AT28C64B-15SU for Recommendation?

The 28C64 from STMicroelectronics is an equivalent alternative to the AT28C64B-15SU. Alternative options include the M93C66 from Microchip Technology and the 64K from Atmel Corporation.
