1.4 Special Function Modules (SFM)
1.4.1 SFM Module - Overview
The PPM3-MK2 programmer features an interchangeable
‘Special Function Module’
. This module
contains all the
‘I/O Driver Circuitry’
which interfaces the programmer to the Target System. In the
event of damage to the programmer driver circuitry, it is possible to remove the complete Special
Function Module and replace it with a new one. This allows the programmer to be repaired in-situ
without the need to send it back to Equinox thereby saving valuable lost production time.
•
The PPM3-MK2 is fitted with the ‘EQ-SFM-1’ module as standard.
•
There are also other SFM modules available which offer faster SPI / JTAG speeds and better
ESD / Over-voltage protection.
