The Microchip Technology Inc. 11AAXXX/11LCXXX (11XX*) devices are a family of 1 Kbit through 16 Kbit Serial Electrically Erasable PROMs. The devices are organized in blocks of x8-bit memory and support the 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 (for 11AAXXX devices), with standby and active currents of only 1 uA and 1 mA, respectively. The 11XX family is available in standard packages including 8-lead PDIP and SOIC, and advanced packaging including 3-lead SOT-23, 8-lead TDFN, and 8-lead MSOP.
