PMBusTM Communication Protocol ACAN-66 Application Note This application note is applicable to the following members of the D1U54P-W1500-12-HxxTC Series: Model Number Number D1U54P-W-1500-12-HC4TC D1U54P-W-1500-12-HA4TC D1U54P-W-1500-12-HB4TC 1 D1U54P-W-1500-12-HC3TC 1 D1U54P-W-1500-12-HA3TC 1 MPS # M1891 M1893 M1895 M1892 M1894 Address Standby Output 3.3Vdc 5Vdc ADDR_SEL 12Vdc (External resistor) 3.3Vdc 5Vdc Airflow Back to Front Front to Back Pending release, consult factory for availability Standard PMBus™ All data communicated over the PMBus™ interface uses PEC (Packet Error Checking) as defined by the standard for PMBus™ Power Systems Management Protocol Part 1 – General Requirements Rev 1.1. Linear data formatting is used for all passed parameters. It is strongly recommended to fully utilize the PEC byte to validate all transactions and to repeat if not validated. Block reads (where the loose byte received denotes the remaining byte to be clocked out) are not supported on this product series. A minimum of 300µs delay between transactions (between the STOP of one command and the START of the next command) is recommended for robust communications. Note: 100KHz I2C communications is supported for the PMBus™ interface. Note: The PMBus™ slave controller does “clock stretch” on ACK or NAK. Device Details Power Supply Controllers Vendor Microchip Technology Inc. Microchip Technology Inc. Power Supply External EEPROM Vendor Microchip Technology Inc. MFG Part Number DSPIC33FJ64GS606T-50I/PT DSPIC33FJ16GS504T-50I/PT Package TQFP64 TQFP44 MFG Part Number 24AA024T-I/MS Package MSOP8 Description ( Secondary) IC Dig SMT Microcontroller PIC33 TQFP64 64k 9kB 50MHz ( Primary) IC Dig SMT Controller PWM Industrial PIC33 TQFP44 40MHz Description IC Dig SMT EEPROM CMOS Serial I2C AT24CXX MSOP8 2kB Device Addressing Methods (See D1U54P-12-CONC Interface Card; Application Note ACAN-64 for Additional Details): There are two methods whereby the three lower order address bits of the seven bit address structure of the internal addressable devices can be assigned (for the secondary microcontroller and the EEPROM device A0, A1 & A2; see the PMBus™ standard). These are as follows: 1. Using the ADDR signal pin (Pin# A3) in digital mode by either: a. Un-terminating (leaving open circuit); this will set a default setting of “111” for the last three addressable bits (A0, A1 & A2) of the seven bit address byte. b. Terminating the pin to RTN/ground (Pin numbers A2/B2); this method will set a default address of “000” for the last three addressable bits (A0, A1 & A2) of the address byte. 2. Using the ADDR signal pin (Pin# A3) in analogue mode by connection of an external resistance to RTN/ground (pin numbers A2/B2). For the possible external resistance values this will result in the following address combinations: HEX Address Combinations by Analogue Method; ADDR External Resistance Values ADDR External Resistance to RTN/Ground Power Module Secondary Power Module (KΩ; ±5% Tolerance) Main Controller (Serial Slave Address)* EEPROM (Serial Slave Address)* 0.82 0xB0 0xA0 2.7 0xB2 0xA2 5.6 0xB4 0xA4 8.2 0xB6 0xA6 15 0xB8 0xA8 27 0xBA 0xAA 56 0xBC 0xAC 180 0xBE 0xAE *The D1U54P-W-1500-12-HxxTC uses 7-bit left shifted” device addressing; the EEPROM addressing follows a similar convention (commences at base address 0xA0); the lowest order bit of the address is the Read/Write bit. It is assumed that the Read Write bit is set to logic “0” (for addresses shown in the table above). www.murata-ps-com/support ACAN-66.A01 Page 1 of 29 PMBusTM Communication Protocol ACAN-66 Application Note PMBus™ Commands Command Code (Hex) Command Name Read / Write Page 00 PAGE R/W All # of Bit # Bytes See Table at rear of Document Link: Operation_Data_01 R/W All 1 ON_OFF_CONFIG 02 See table at rear of Document Link: ON_OFF_Data_02 R All 1 03 CLEAR_FAULTS W All 1 10 WRITE_PROTECT R/W All 1 5:0 7:6 Turn the unit on/off in conjunction with digital input from PSON_H YES Set when Turn off immediately (default) / 0 = Use delay @ turn-off Set when Power on processing is active high (default) Set when Use CONTROL pin for on/off power processing (default) Set when Use OPERATION command for on/off power processing (default) Set when Use both CONTROL pin & OPERATION command (default) YES YES YES 0 1 2 ON_OFF_DELAY ON_OFF_POLARITY USE_CONTROL 3 USE_OPERATION 4 5 6 7 USE_CNTL_AND _OP RESERVED RESERVED RESERVED Write only command clears all faults that have been set in all the STATUS_XXXX registers simultaneously Disable all writes except: WRITE_PROTECT Disable all writes except: WRITE_PROTECT, OPERATION, PAGE Disable all writes except: WRITE_PROTECT, OPERATION, PAGE, ON_OFF_CONFIG, VOUT_COMMAND Enable all writes 0:3 19 CAPABILITY R All 4 SMBALERT_L 6:5 MAX_BUS_SPEED 7 PEC VOUT_MODE R 0 1 20 VSTBY_MODE R 1 1 21 VOUT_COMMAND R/W All 2 25 VOUT_MARGIN_HIGH R/W 0 2 25 VSTBY_MARGIN_LOW R/W 1 2 26 VOUT_MARGIN_HIGH R/W 0 2 26 VSTBY_MARGIN_LOW R/W 1 2 2 FAN_CONFIG_1_2 R All 1 NO YES YES NO NO NO YES YES Set when device has SMBALERT_L pin which supports the SMBus Alert Response protocol 01 = Max supported bus speed = 400kHz; 00 Max supported bus speed = 100kHz Set when packet error checking is supported Single data byte sets the READ_VOUT sensor to linear mode data format and supplies N exponent for translation to volts PMBus Spec - Part II - Revision 1.1 - Sections 8.1-8.3 Single data byte sets the READ_VSTBY sensor to linear mode data format and supplies N exponent for translation to volts PMBus Spec - Part II - Revision 1.1 - Sections 8.1-8.3 YES YES YES YES YES YES 0 1 3A YES NO RESERVED 1 20 Supported ?
