Revisions EXX and later are affected.
Reason for the Change
The Intel Enpirion family of power modules has been discontinued by the manufacturer. Enpirion regulators are used on the XEM7360 to generate several of the on-board system and VCCO supplies. Opal Kelly has identified suitable replacement parts for these supplies.
Description of the Change
The Enpirion devices on the XEM7360 are being replaced as described in the table below.
|Reference||Voltage||Application||Original P/n||Replacement P/N|
|U3+U5||1.0 V||FPGA VCCINT and VCCBRAM||Intel EN5394QI||Infineon IR38063MTRPBF (U3 only)|
|U2||3.3 V||Miscellaneous system functions||Intel EN5322QI||Microchip MIC23153YMT|
|U4||1.8 V||FPGA VCCAUX, host interface||Intel EN5337QI||MPS MP2316GD-P|
|U6||1.5 V||DDR3||Intel EN5394QI||Alpha & Omega AOZ2262NQI-11 (now U5)|
|U9||2.0 V||FPGA VCCAUX_IO||Intel EP5348UI||Maxim MAX25300BATA/V+|
|U30||VADJ1||Adjustable supply voltage for FPGA banks 15, 16||Intel EN5322QI||Semtech SC186ULTRT¹|
|U31||VADJ2||Adjustable supply voltage for FPGA bank 12||Intel EN5322QI||Semtech SC186ULTRT¹|
|U33||VADJ3||Adjustable supply voltage for FPGA bank 32||Intel EN5322QI||Semtech SC186ULTRT¹|
- The Semtech SC186ULTRT is capable of the same set of output voltages as the Intel EN5322QI. There is no change to VADJ configuration as described in Device Settings.
