ATF1508ASV(L) devices are in-system programmable (ISP) devices utilizing the 4-pin
JTAG protocol. This capability eliminates package handling normally required for pro-
gramming and facilitates rapid design iterations and field changes.

ATF1508ASV(L) via the PC. ISP is performed by using either a download cable, a com-
parable board tester or a simple microprocessor interface.
To allow ISP programming support by the Automated Test Equipment (ATE) vendors,
Serial Vector Format (SVF) files can be created by the Atmel ISP software. Conversion
to other ATE tester format beside SVF is also possible
ATF1508ASV(L) devices can also be programmed using standard third-party program-
mers. With third-party programmer, the JTAG ISP port can be disabled thereby allowing
four additional I/O pins to be used for logic.
Contact your local Atmel representatives or Atmel PLD applications for details.
The ATF1508ASV(L) has a special feature that locks the device and prevents the inputs
and I/O from driving if the programming process is interrupted for any reason. The
inputs and I/O default to high-Z state during such a condition. In addition the pin-keeper
option preserves the former state during device programming.
All ATF1508ASV(L) devices are initially shipped in the erased state thereby making
them ready to use for ISP.

CPLDs” application note.
