D1U54P-W-650-12-HBxC-xxx PMBusTM Communications Protocol ACAN-59 Application Note PMBus™ Commands & Features This application note is applicable for the following members of the D1U54P-W-650-12-HBxC-xxx Series: MPS# Model Number M1845 N/A M1876 D1U54P-W-650-12-HB4C M1871 D1U54P-W-650-12-HB4C-AB M1877 D1U54P-W-650-12-HB3C M1872 D1U54P-W-650-12-HB3C-AB Serial Communication Slave Addressing Airflow Standby (Vdc) Back-to-Front ADDR_Select (External Resistor) 12 front-to-back Standard PMBus™ Commands 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: 100/400 KHz I2C communications is supported for the PMBus™ interface. Note: The PMBus™ slave controller does “clock stretch” on ACK or NAK.

Manufacturers Part Number DSPIC33FJ16GS504T-50I/PT DSPIC33FJ64GS606T-50I/PT 24AA024T- I /MS Package Description 44 Pin 64 Pin 8 Pin Primary Digital Signal Controller, 16-bit dsPIC, 32K flash, 2K SRAM, --40C to +85C Secondary Digital Signal Controller, 16-bit dsPIC, 64K flash, 9K SRAM, -40C to +85C 2K Bit, 2.5-5.5V, 400KHz, 1.8-2.5V 100KHz, -40C to +85C 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-650-12-HBxC-xxx 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 08 Feb 2016 ACAN59.A01 Page 1 of 23 D1U54P-W-650-12-HBxC-xxx PMBusTM Communications Protocol ACAN-59 Application Note PMBus™ COMMANDS Command Codes Page Command is supported to allow the ability to control and monitor the dual outputs (the Main 1 output and VSTANDBY outputs).
