FAQ

What is the maximum operating frequency supported by XC4006E-4PG156I?

The XC4006E-4PG156I has a -4 speed grade specifying a maximum internal clock frequency of 125 MHz under industrial temperature and voltage conditions. This value applies to critical logic paths with proper placement and routing; actual system clock rates depend on design topology and I/O timing constraints.

Does XC4006E-4PG156I require external configuration memory?

Yes, XC4006E-4PG156I uses SRAM-based configuration and requires external non-volatile memory (e.g., serial PROM) to store the bitstream. Configuration occurs on power-up via master serial or slave parallel mode, as defined by mode pin settings at startup.

Is XC4006E-4PG156I pin-compatible with other XC4000E family members in the same package?

XC4006E-4PG156I shares the 156-pin PQFP footprint and pinout with other XC4000E devices in PG156 packaging, including XC4004E and XC4008E variants. Signal assignments for power, ground, clocks, and JTAG are identical; I/O pin functions are user-defined during configuration.

What is the I/O voltage tolerance of XC4006E-4PG156I?

XC4006E-4PG156I features 5 V-tolerant I/Os compatible with TTL and CMOS logic levels. Inputs accept 0–5.5 V regardless of VCC, and outputs drive to full 5 V swing-enabling direct interfacing with legacy 5 V systems without level-shifting circuitry.

Can XC4006E-4PG156I be reprogrammed in-system?

Yes, XC4006E-4PG156I supports in-system programming via its IEEE 1149.1 JTAG interface (TCK/TMS/TDI/TDO pins). Reprogramming requires a JTAG controller and valid configuration bitstream; no power cycle is needed for configuration reload after PROGRAM assertion.
