The device is optimized for use in many industrial and mercial applications where low-power and low-voltage operations are essential. The LR24C02/LR24C04/LR24C08/LR24C16 is available in space-saving 8-lead PDIP, 8-lead SOP, and 8-lead TSSOP packages and is accessed via a two-wire serial interface. Pin Descriptions 1/15 Block Diagram LESHAN RADIO PANY, LTD. 2/15 LESHAN RADIO PANY, LTD. DEVICE/PAGE ADDRESSES (A2, A1 and A0): The A2, A1 and A0 pins are device address inputs that are hard wired for the LR24C02. Eight 2K devices may be addressed on a single bus system (device addressing is discussed in detail under the Device Addressing section). The LR24C04 uses the A2 and A1 inputs for hard wire addressing and a total of four 4K devices may be addressed on a single bus system. The A0 pin is a no connect and can be connected to ground. The LR24C08 only uses the A2 input for hardwire addressing and a total of two 8K devices may be addressed on a single bus system. The A0 and A1 pins are no connects and can be connected to ground. The LR24C16 does not use the device address pins, which limits the number of devices on a single bus to one. The A0, A1 and A2 pins are no connects and can be connected...
