AT27C512R-45JU Typical application Circuitry

AT27C512R-45JU

The AT27C512R-45JU is a high-performance, low-power OTP (one-time programmable) EPROM (erasable programmable read-only memory) device by Microchip Technology. The main functionality of this chip is non-volatile data storage, capable of retaining information even without power supply.

Key features of the AT27C512R-45JU:

1. Functionality: The AT27C512R-45JU is an OTP EPROM, allowing for programming once and retaining the stored information indefinitely.

2. Storage Capacity: It provides a memory of 512Kbit (64KB), doubling the storage space provided by its predecessor, the AT27C256R-70PU.

3. Speed: The device delivers an access time of 45ns, permitting speedy data retrieval.

4. Operating Voltage: The chip operates over a voltage range of 4.5V to 5.5V.

5. Packaging: The AT27C512R-45JU comes in a PLCC (Plastic Leaded Chip Carrier) 32-pin package, differentiating it from the DIP packaging of the AT27C256R-70PU.

Applications of AT27C512R-45JU:

The AT27C512R-45JU is often used in sectors such as medical electronics, automotive systems, industrial control systems, and any area that requires dependable non-volatile data storage.

Circuit Connection - Example in Medical Electronics Application:

Here's how to connect the AT27C512R-45JU in a medical electronics application:

- Pin 16 (VCC): This is the supply voltage pin, which should be connected to a voltage supply ranging from 4.5V to 5.5V.

- Pin 8 (GND): Attach this pin to the system's ground.

- Pins 15 (CE - Chip Enable) and 20 (OE - Output Enable): Connect these control pins to your control unit, such as a microprocessor or microcontroller. For data access from the EPROM, both pins should be in the low state.

- Pins 4 to 7, and 9 to 14 (A0 to A10) and Pins 23 to 31 (A11 to A18): These are the address input pins, which should be driven by the control unit to designate the memory location from which data will be read.

- Pins 1 to 3, and 19 to 22 (Q0 to Q7): Data stored at the specified address is presented at these data output pins.

Design Considerations for AT27C512R-45JU:

1. Programming Precautions: Be aware that the AT27C512R-45JU can only be programmed once. Make sure your data is accurate and finalized before programming.

2. Power Supply Decoupling: Use a decoupling capacitor (e.g., 0.1uF) near the VCC and GND pins of the AT27C512R-45JU to mitigate noise interference.

3. Data Access: Before bringing the Chip Enable (CE) and Output Enable (OE) pins low, the address must always be stabilized.

4. Protection: It is essential to safeguard the AT27C512R-45JU from overprogramming voltage and electrostatic discharges to avoid permanent damage to the device.

The AT27C512R-45JU ensures trustworthy and efficient memory storage, proving itself an essential component in a variety of applications.
