Review ATMEL Lot Of And 256kbit Ceramic Ic

The Atmel AT28C256-25DI and AT28C256-15DI are 256 kilobit (32 kilobytes x 8) one-time programmable (OTP) and mask ROM ceramic dip-28 Integrated Circuits (ICs) manufactured by Microchip Technology Inc. following Atmel's legacy. These ICs are ideal for various applications, including data logging, automotive, industrial, and consumer electronics.

The main difference between the two is their pin configuration: The AT28C256-25DI features a 25-pin DIP (Dual In-line Package), while the AT28C256-15DI comes with a 15-pin DIP. This pin count difference allows for more I/O pins and additional features on the 25-pin variant, making it a more versatile option for certain applications.

Both ICs offer eight data I/O lines, a chip select input, a write protect input, and a power-on reset input. The write protect input can be used to prevent inadvertent programming, making it suitable for applications where data should not be changed after manufacturing.

The AT28C256-25DI and AT28C256-15DI are built using CMOS (Complementary Metal-Oxide-Semiconductor) technology, ensuring low power consumption and excellent reliability. They operate over a wide temperature range of -40 C to 85 C, making them suitable for use in various environments.

These ICs include an internal oscillator that supports clock frequencies up to 20 MHz, enabling fast data transfer and processing. They also support various programming interfaces, including I C, SPI, and serial-parallel. This flexibility makes them easy to integrate into various systems and designs.

The AT28C256-25DI and AT28C256-15DI come in a compact DIP package, measuring 26.5 mm x 20.5 mm (1.04 inches x 0.81 inches) for the 25-pin variant and 21.6 mm x 13.8 mm (0.85 inches x 0.54 inches) for the 15-pin variant. This compact size makes them suitable for use in space-constrained applications.

In summary, the Atmel AT28C256-25DI and AT28C256-15DI are versatile and reliable 256 kilobit OTP and mask ROM ceramic dip-28 ICs. Their wide range of features, pin configurations, and compatibility with various programming interfaces make them suitable for various applications in different industries.

The Atmel AT28C256 is a 256 kilobytes (KB) flash memory IC (Integrated Circuit) available in two different packages: 28-pin DIP (Dual In-line Package) with 15 input/output (I/O) pins labeled (AT28C256-15DI) and 28 input/output pins labeled (AT28C256-25DI). Here are some pros and cons of buying this IC:

1. Large memory capacity: The AT28C256 offers a large memory capacity of 256 kilobytes, making it suitable for storing large amounts of data or code.

2. Low power consumption: This IC has a low power consumption, which can be beneficial for battery-powered applications.

3. Wide operating temperature range: It can operate in a wide temperature range, making it suitable for use in various environments.

4. Easy to use: The AT28C256 is a simple and easy-to-use IC. It has a straightforward interface and can be programmed using standard flash memory programming tools.

5. Reliable: Atmel is a well-known and reputable semiconductor manufacturer, ensuring the reliability and quality of their products.

1. Limited input/output pins: Compared to other memory ICs with similar capacities, the AT28C256 has a limited number of input/output pins, which may limit its flexibility in certain applications.

2. DIP packaging: The DIP packaging may be less ideal for applications where space is a concern, as it requires more board space compared to other packaging options.

3. Programming requires additional hardware: To program the AT28C256, you will need additional hardware such as a programmer, which may add to the overall cost.

The Atmel AT28C256 is a reliable and easy-to-use flash memory IC with a large capacity and low power consumption. However, it has a limited number of input/output pins and requires additional hardware for programming. If you have an application that requires a large memory capacity and low power consumption, and you don't mind the additional cost and limitations of the DIP packaging and programming hardware, then the AT28C256 could be a good choice for you.

If you're looking for a similar memory IC with more input/output pins, you may want to consider other ICs with parallel or serial interface, such as the Atmel AT28C512 or the Microchip 25LC040. These ICs offer more input/output pins and may be more suitable for applications where flexibility is a concern. However, they may have different capacities and power consumption levels, so it's essential to consider the specific requirements of your application before making a decision.
