vides Teradyne users with: advanced JTAG control using vacant slots on a Teradyne multi-function application board; configuration versatili- ty — allowing up to two Test Access Ports (TAPs) with a single CFM slot or up to four TAPs using expander mod- ules; independently adjust - able TAP interface voltages from 1.25 to 3.3V; high-speed 100MHz test clock rate for boundary-scan test support; compatibility with advanced IEEE-1149.6 AC-coupled digi- tal networks; in-system program- ming of flash and CPLD devices including direct SPI and I2
C support. The QuadTAP/CFM is a single
slot custom functional module (CFM) form factor board that installs direct- ly into one of four slots on a Teradyne multi-function application board. Integration is simple and transpar- ent; once installed in the system, up to eight signals of the QuadTAP/CFM JTAG, GPIO, I2
C, and SPI are avail-
able to test fixtures and the tester backplane. Additional signals are made available using the included
Quadtap and Expander both feed the Teradyne ICT.
