The device is organized in blocks of x8-bit memory and support the patented* single I/O UNI/O(R) serial bus. By using Manchester encoding techniques, the clock and data are combined into a single, serial bit stream (SCIO), where the clock signal is extracted by the receiver to correctly decode the timing and value of each bit. Low-voltage design permits operation down to 1.8V, with standby and active currents of only 1 uA and 1 mA, respectively. The 11AA02E48 is available in standard 8-lead SOIC and 3-lead SOT-23 packages.

They can be interfaced with microcontrollers, including Microchip's PIC(R) microcontrollers, ASICs, or any other device with an available discrete I/O line that can be configured properly to match the UNI/O protocol. The 11AA02E48 devices contain an 8-bit instruction register. The devices are accessed via the SCIO pin. Data is embedded into the I/O stream through Manchester encoding. The bus is controlled by a master device which determines the clock period, controls the bus access and initiates all operations, while the 11AA02E48 works as slave. Both master and slave can operate as transmitter or receiver, but the master device determines which mode is active.

R/W Control This data sheet documents only the device's features and specifications that are in addition to the features and specifications of the 11AA020 device. For information on the features and specifications shared by the 11AA02E48 and 11AA020 devices, see the "11AAXXX/11LCXXX Family Data Sheet" (DS22067). (c) 2008 Microchip Technology Inc. Preliminary DS22122A-page 5 11AA02E48 3.0 PRE-PROGRAMMED EUI-48TM NODE ADDRESS The 11AA02E48 is programmed at the factory with a globally unique, EUI-48TM and EUI-64TM compatible node address stored in the upper 1/4 of the array and write-protected through the STATUS register. The remaining 1,536 bits are available for application use. The 6-byte EUI-48TM node address value is stored in array locations 0xFA through 0xFF, as shown in Figure 3-2. The first 3 bytes are the Organizationally Unique Identifier (OUI) assigned to Microchip by the IEEE Registration Authority. The remaining 3 bytes are the Extension Identifier, and are generated by Microchip to ensure a globally-unique, 48-bit value. 3.1 FIGURE 3-1: MEMORY ORGANIZATION 00h Standard EEPROM Write-Protected EUI-48TM Block FIGURE 3-2: EUI-64TM Support The pre-programmed EUI-48 node address can easily be encapsulated at the application level to form a globally unique, 64-bit node address for systems utilizing the EUI-64 standard. This is done by adding 0xFFFE between the OUI and the Extension Identifier, as shown below. C0h FFh EUI-48 NODE ADDRESS PHYSICAL MEMORY MAP EXAMPLE 24-bit Organizationally Unique Identifier Description Data 00h Array Address FAh 04h A3h 24-bit Extension Identifier 12h 34h 56h FFh Corresponding EUI-48TM Node Address: 00-04-A3-12-34-56 Corresponding EUI-64TM Node Address: 00-04-A3-FF-FE-12-34-56 3.2 Factory-Programmed Write Protection In order to help guard against accidental corruption of the EUI-48 node address, the BP1 and BP0 bits of the STATUS register are programmed at the factory to `0' and `1', respectively, as shown in the following table: 7 X -- 6 X -- 5 X -- 4 X -- 3 BP1 0 2 BP0 1 1 WEL -- 0 WIP -- This protects the upper 1/4 of the array (0xC0 to 0xFF) from write operations. This array block can be utilized for writing by clearing the BP bits with a Write Status Register (WRSR) instruction. Note that if this is performed, care must be taken to prevent overwriting the EUI-48 value.

Note the following details of the code protection feature on Microchip devices: * Microchip products meet the specification contained in their particular Microchip Data Sheet. * Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions. * There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip's Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property. * Microchip is willing to work with the customer who is concerned about the integrity of their code. * Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as "unbreakable." Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our products.
