XEM7360
Device Settings
The XEM7360 supports the FrontPanel Device Settings in the table below, accessible from the FrontPanel Application as well as the Device Settings API.
Note: All VADJ device settings require a power cycle to take effect.
Fan Control Device Settings
You may optionally connect a fan to JP1 (Molex 53398-0271). This connector drives a signal to the fan according to the Device Settings. For most applications, we recommend binary operating mode and enabling the fan at all times. You may optionally configure a temperature control whereby the output is switched based on the measured temperature of the FPGA die.
| NAME | TYPE | DESCRIPTION |
|---|---|---|
| XEM7360_VADJ1_VOLTAGE | INT32 | Vadj1 output voltage specified in 10’s of mV. For example, “330” would set Vadj1 = 3.3v. Valid settings are 330, 250, 180, 150, 125, 120. Rev EXX valid settings are 330, 300, 280, 260, 250, 220, 180, 150, 130, 125, 120. DEFAULT: 120 |
| XEM7360_VADJ2_VOLTAGE | INT32 | Vadj2 output voltage specified in 10’s of mV. For example, “330” would set Vadj2 = 3.3v. Valid settings are 330, 250, 180, 150, 125, 120. Rev EXX valid settings are 330, 300, 280, 260, 250, 220, 180, 150, 130, 125, 120. DEFAULT: 120 |
| XEM7360_VADJ3_VOLTAGE | INT32 | Vadj3 output voltage specified in 10’s of mV. For example, “180” would set Vadj3 = 1.8v. Vadj3 connects to a High Performance bank and supports a maximum of 1.8v. Valid settings are 180, 150, 125, 120. Rev EXX valid settings are 180, 150, 130, 125, 120. DEFAULT: 120 |
| XEM7360_VADJ_MODE | INT32 | (1:0) : Vadj1 mode (3:2) : Vadj2 mode (5:4) : Vadj3 mode (6) : Reserved (7) : Vadj output enable: 0=disable, 1=enable, Applies to ALL Vadj. Vadj Modes: 0=Minimum setting (1.2V) 1=IPMI setting only. If a valid IPMI EEPROM is not found, Vadj is set to its minimum setting (1.2V). 2=IPMI with fallback. If a valid IPMI EEPROM is not found, Vadj is set according to XEM7360_VADJx_VOLTAGE. 3=IPMI ignore. IPMI settings are ignored and Vadj is set according to XEM7360_VADJx_VOLTAGE. DEFAULT: 170 (0xAA) – Each Vadj at mode 2 with output enabled. |
| XEM7360_STATUS | INT32 | Read-only register that contains status during runtime. [0] – POK_3V3 [1] – POK_VADJ [2] – PRSNT_M2C_L [7:3] – RESERVED |
| XEM7360_FAN_MODE | INT32 | 0=Binary mode 1=Temperature controlled mode DEFAULT: 0 |
| XEM7360_FAN_ENABLE | INT32 | In binary mode, 0=disable, 1=enable DEFAULT: 1 |
| XEM7360_FAN_TEMP_THRESHOLD FW 1.31 and before | INT32 | In temperature controlled mode, the number here represents the lower threshold (in degrees Celsius) for temperature-dependent operation. At THRESH, fan control PWM=0%. At THRESH+16C, fan control PWM=50%. At THRESH+32C, fan control PWM=100%. |
| XEM7360_FAN_TEMP_THRESHOLD FW 1.42+ | INT32 | In temperature controlled mode, the number here represents the threshold (in degrees Celsius) for fan enable. At THRESH, fan is enabled At THRESH-10C, fan is disabled DEFAULT: 16C |
