AT27C256R-70PU Typical application Circuitry

AT27C256R-70PU

The AT27C256R-70PU is a 256Kbit, low-power, high-performance OTP (one-time programmable) EPROM, manufactured by Microchip Technology. It offers non-volatile memory storage and features a rapid programming algorithm for efficient operation.

Characteristic Features of the AT27C256R-70PU:

1. Functionality: The AT27C256R-70PU is an OTP EPROM. Once configured, it preserves the data even when the power is turned off.

2. Performance: The device offers a 70ns access time, allowing for fast data retrieval.

3. Storage Capacity: It provides 256Kbit (32KB) of memory.

4. Supply Voltage: It operates over a wide voltage range of 4.5V to 5.5V.5. Packaging: A 28-pin DIP (Dual Inline Package) is provided for the chip.

Applications of AT27C256R-70PU:

The AT27C256R-70PU finds applications in a variety of sectors, including Industrial control systems, medical electronics, automotive systems, and any system that requires non-volatile data storage.

Circuit Connection - Industrial Control System Application:

For an industrial control system application, here's how you could connect the AT27C256R-70PU:

- Pin 14 (VCC): This is the supply voltage pin. Connect this to the positive supply, which should be between 4.5V to 5.5V.

- Pin 7 (GND): Connect this pin to the ground of your system.

- Pins 11 (CE - Chip Enable) and 12 (OE - Output Enable): These are the control pins. Typically, they are directly connected to the control unit (like a microcontroller or a microprocessor) of the system. To access data from the EPROM, both of these pins should be in the low state.

- Pins 13 (A0) to 19 (A10) and Pins 21 (A11) to 32 (A17): These are the address input pins, which should be driven by the control unit to specify the memory location from which data is to be read.

- Pins 1 (Q0) to 8 (Q7): These are the data output pins. The data stored at the specified address is presented at these pins.

Design Considerations when using AT27C256R-70PU:

1. Programming: It's important to note that the AT27C256R-70PU can be programmed only once. Thus, ensure your data is accurate and complete before programming.

2. Power Supply Decoupling: To prevent noise interference, place a decoupling capacitor (typically 0.1uF) close to the VCC and GND pins of the AT27C256R-70PU.

3. Data Access: Before bringing the Chip Enable (CE) and Output Enable (OE) pins low, be sure the address is stable.. Changes in address, while the chip is enabled, could lead to incorrect data being accessed.

4. Protection: It's crucial to protect the AT27C256R-70PU from excessive programming voltage or electrostatic discharge, as it may lead to irreversible damage to the device.

The AT27C256R-70PU offers reliable and efficient memory storage, making it a valuable component in a variety of applications.
