Available Temperature Ranges: Pin Function Table Description: The Microchip Technology Inc. 11AA02E48 device is a 2 Kbit Serial Electrically Erasable PROM. The device is organized in blocks of x8-bit memory and support the patented* single I/O UNI/O ® 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.

2.0 FUNCTIONAL DESCRIPTION

2.1 Principles of Operation

The 11AA02E48 family of serial EEPROMs support the UNI/O ® protocol. They can be interfaced with microcontrollers, including Microchip’s PIC® microcon- trollers, 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, con- trols 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. FIGURE 2-1: BLOCK DIAGRAM Note: This data sheet documents only the device’s features and specifications that are in addition to the features and specifi- cations of the 11AA020 device. For infor- mation on the features and specifications shared by the 11AA02E48 and 11AA020 devices, see the “ 11AAXXX/11LCXXX Family Data Sheet” (DS22067).

3.0 PRE-PROGRAMMED EUI-48™

The 11AA02E48 is programmed at the factory with a globally unique, EUI-48™ and EUI-64™ 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. FIGURE 3-1: MEMORY ORGANIZATION The 6-byte EUI-48™ 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 Micro- chip to ensure a globally-unique, 48-bit value.

3.1 EUI-64™ Support

The pre-programmed EUI-48 node address can easily be encapsulated at the application level to form a glob- ally 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. FIGURE 3-2: EUI-48 NODE ADDRESS PHYSICAL MEMORY MAP EXAMPLE

3.2 Factory-Programmed Write

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: 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 per- formed, care must be taken to prevent overwriting the EUI-48 value. 00h C0h FFh Write-Protected EUI-48™ Block Standard EEPROM FAh FFh 24-bit Organizationally Unique Identifier 24-bit Extension Identifier 00h 04h A3h 12h 34h 56h Corresponding EUI-48™ Node Address: 00-04-A3-12-34-56

4.0 PIN DESCRIPTIONS

The descriptions of the pins are listed in Table 4-1. TABLE 4-1: PIN FUNCTION TABLE

4.1 Serial Clock, Data Input/Output

(SCIO) SCIO is a bidirectional pin used to transfer commands and addresses into, as well as data into and out of, the device. The serial clock is embedded into the data stream through Manchester encoding. Each bit is rep- resented by a signal transition at the middle of the bit period.
