LHCb week February 2003 D.Charlet SPECS slave mezzanine board

LHCb week February 2003 D.Charlet Functionalities of the mezzanine  8 switches will be available to fix the SPECS slave address and 4 for the broadcast group address (one by type of board for instance).  One PROM will allow the ECS system to get information about the concerned front-end element. It will be mounted on a socket.  8 software programmable I2C/JTAG differential outputs. Each of them can individually be dedicated to one type of bus.  One local I2C bus and one local JTAG bus.  One parallel bus.  One decoder for the channel B of the TTCrx will be implemented within the SPECS slave chip. It will decode the necessary functions (currently L0 counter reset and Test pulse). Others ?  One 32-bit static register to control the local environment (would 16 be enough ? ). We are looking at the possibility to put an 8 bit ADC on this board, for slow measurements like temperature, etc... The problem is actually to find a sufficiently rad-hard one …
