FPGA Master Serial Mode Summary
The I/O and logic functions of any SRAM-based FPGA are established by a configuration pro-
gram. The program is loaded either automatically upon power-up, or on command, depending
on the state of the FPGA mode pins. In Master mode, the FPGA automatically loads the config-
uration program from an external memory. The AT17F Serial Configuration PROM has been
designed for compatibility with the Master Serial mode.
This document discusses the Atmel AT40K, AT40KAL and AT94KAL applications as well as Xil-
inx applications.
7.
Control of Configuration
Most connections between the FPGA device and the AT17F Serial Configurator PROM are sim-
ple and self-explanatory.
The DATA output of the AT17F Series Configurator drives DIN of the FPGA devices.
The master FPGA CCLK output drives the CLK input of the AT17F Series Configurator.
The CEO output of any AT17F Series Configurator drives the CE input of the next
Configurator in a cascade chain of configurator devices.
SER_EN must be at logic high level (internal pull-up provided) except during ISP.
The READY pin is available as an open-collector indicator of the device’s reset status; it is
driven Low while the device is in its power-on reset cycle and released (tri-stated) when the
cycle is complete.
PAGE_EN must be held Low if download paging is not desired. The PAGESEL[1:0] inputs
must be tied off High or Low. If paging is desired, PAGE_EN must be High and the PAGESEL
pins must be set to High or Low such that the desired page is selected, see Table 5-2 on
8.
Cascading Serial Configuration Devices
For multiple FPGAs configured as a daisy-chain, or for FPGAs requiring larger configuration
memories, cascaded configurators provide additional memory.
After the last bit from the first configurator is read, the clock signal to the configurator asserts its
CEO output Low and disables its DATA line driver. The second configurator recognizes the Low
level on its CE input and enables its DATA output.
After configuration is complete, the address counters of all cascaded configurators are reset if
the RESET/OE on each configurator is driven to its active (Low) level.
If the address counters are not to be reset upon completion, then the RESET/OE input can be
tied to its inactive (High) level.
9.
Programming Mode
The programming mode is entered by bringing SER_EN Low. In this mode the chip can be pro-
grammed by the 2-wire serial bus. The programming is done at V
CC supply only. Programming
super voltages are generated inside the chip. The AT17F parts are read/write at 3.3V nominal.
