R1EX24256ASASOA

The R1EX24256ASASOA is a Serial EEPROM (Electrically Erasable Programmable Read-Only Memory) manufactured by Renesas Electronics Corporation. It is designed to store small amounts of data in various electronic devices. Here's an overview of the R1EX24256ASASOA:

**Functionality and Features:**

The R1EX24256ASASOA is an EEPROM memory chip with the following key features:

1. **Serial Interface:** The EEPROM uses a serial communication protocol such as I2C (Inter-Integrated Circuit) to communicate with a microcontroller or other devices.

2. **Non-Volatile Storage:** EEPROMs are non-volatile memory devices, which means they can retain data even when the power is turned off.

3. **High Storage Density:** The "24256" in the part number typically indicates the storage capacity, which is 256 kilobits (32 kilobytes) in this case.

4. **Low Power Consumption:** EEPROMs are designed for low-power applications, making them suitable for battery-powered devices.

5. **Write Protection:** Some EEPROMs, including the R1EX24256ASASOA, offer write protection features to prevent accidental or unauthorized modification of stored data.

**Parameters:**

- **Memory Size:** The R1EX24256ASASOA has a memory size of 256 Kbits or 32 Kbytes.
