Spartan-II/Spartan-IIE Family OTP Configuration PROMs (XC17S00A)
DS078 (v1.10) June 25, 2007
Product Specification
4
R
Standby Mode
The PROM enters a low-power standby mode whenever CE
is asserted High. The output remains in a high-impedance
state regardless of the state of the OE input.
Programming Spartan-II/Spartan-IIE
Family PROMs
The devices can be programmed on programmers supplied
by Xilinx or qualified third-party vendors. The user must
ensure that the appropriate programming algorithm and the
latest version of the programmer software are used. The
wrong choice can permanently damage the device.
Caution! Always tie the two VCC pins together.
