65K, 128K and 256K
The AT17C65/128/256 and AT17LV65/128/256 (AT17 Series) FPGA Configuration
EEPROMS (Configurator) provide an easy-to-use, cost-effective configuration mem-
ory for Field Programmable Gate Arrays. The AT17 Series is packaged in the 8-pin
DIP and the popular 20-pin PLCC and SOIC. The AT17 Series family uses a simple
serial-access procedure to configure one or more FPGA devices. The AT17 Series
organization supplies enough memory to configure one or multiple smaller FPGAs.
Using a special feature of the AT17 Series, the user can select the polarity of the reset
function by programming a special EEPROM bit.

Controlling The AT17 Series Serial EEPROMs
Most connections between the FPGA device and the Serial
tion cycle. If a system reset is applied to the FPGA, it will
EEPROM are simple and self-explanatory.
abort the original configuration and then reset itself for a
new configuration, as intended. Of course, the AT17 Series
does not see the external reset signal and will not reset its
internal address counters and, consequently, will remain
out of sync with the FPGA for the remainder of the configu-
ration cycle.
• The DATA output of the AT17 Series drives DIN of the
FPGA devices.
• The master FPGA CCLK output drives the CLK input of
the AT17 Series.
Condition 2
• The CEO output of any AT17C/LV128/256 drives the CE
input of the next AT17C/LV128/256 in a cascade chain of
PROMs.
The FPGA D/P output drives only the CE input of the AT17
Series, while its OE input is driven by the inversion of the
input to the FPGA RESET input pin. This connection works
under all normal circumstances, even when the user aborts
a configuration before D/P has gone High. A High level on
the RESET/OE input to the AT17C/LVxxx – during FPGA
reset – clears the Configurator's internal address pointer,
so that the reconfiguration starts at the beginning. The
AT17 Series does not require an inverter since the RESET
polarity is programmable.
• SER_EN must be connected to VCC
.
There are, however, two different ways to use the inputs
CE and OE, as shown in the AC Characteristics wave-
forms.
Condition 1
The simplest connection is to have the FPGA D/P output
drive both CE and RESET/OE in parallel (Figure 1). Due to
its simplicity, however, this method will fail if the FPGA
receives an external reset condition during the configura-

I
RESET/Output Enable input (when SER_EN is High). A Low level on both the
CE and RESET/OE inputs enables the data output driver. A High level on
RESET/OE resets both the addresss and bit counters. A logic polarity of this
input is programmable as either RESET/OE or RESET/OE. This document
describes the pin as RESET/OE.

RESET/OE
CE
I
Chip Enable input. Used for device selection. A Low level on both CE and OE
enables the data output driver. A High level on CE disables both the address
and bit counters and forces te device into a low power mode. Note this pin will
not enable/disable the device in 2-wire Serial mode (ie; when SER_EN is Low).

GND
CEO
Ground Pin
O
Chip Enable Out output. This signal is asserted Low on the clock cycle following
the last bit read from the memory. It will stay Low as long as CE and OE are
both Low. It will then follow CE until OE goes High. Thereafter CEO will stay
High until the entire PROM is read again and senses the status of RESET
polarity.
A2

I
Device selection input, A2. This is used to enable (or select) the device during
programming and when SER_EN is Low (see Programming Guide for more
details).
Serial enable is normally high during FPGA loading operations. Bringing
SER_EN low, enables the 2-wire serial interface for programming.

After configuration is complete, the address counters of all
cascaded Configurators are reset if the reset signal drives
the RESET/OE on each Configurator Active.
FPGA Master Serial Mode Summary
The I/O and logic functions of the FPGA and their associ-
ated interconnections are established by a configuration
program. The program is loaded either automatically upon
power up, or on command, depending on the state of the
three FPGA mode pins. In Master Mode, the FPGA auto-
matically loads the configuration program from an external
memory. The Serial Configuration EEPROM has been
designed for compatibility with the Master Serial Mode.
If the address counters are not to be reset upon comple-
tion, then the RESET/OE inputs can be tied to ground. For
more details, please reference the AT17C Series Program-
ming Guide.
Programming Mode
The programming mode is entered by bringing SER_EN
Low. In this mode the chip can be programmed by the 2-
wire interface. The programming is done at VCC supply
only. Programming super voltages are generated inside the
chip. See the Programming Specification for Atmel's Con-
figuration Memories Application Note for further informa-
tion. The AT17C Series parts are read/write at 5V nominal.
The AT17LV parts are read/write at 3.0V nominal.
Cascading Serial Configuration
EEPROMs
(AT17C/LV128 and AT17C/LV256)
For multiple FPGAs configured as a daisy-chain, or for
future FPGAs requiring larger configuration memories, cas-
caded Configurators provide additional memory (17C/
LV128 and 17C/LV256 only).
After the last bit from the first Configurator is read, the next
clock signal to the Configurator asserts its CEO output Low
and disables its DATA line. The second Configurator recog-
nizes the Low level on its CE input and enables its DATA
output.
AT17C/LVXXX Reset Polarity
The AT17C/LVXXX lets the user choose the reset polarity
as either RESET/OE or RESET/OE.
Standby Mode
Figure 1. Condition 1 Connection
The AT17C/LVXXX enters a low-power standby mode
whenever CE is asserted High. In this mode, the Configura-
tor consumes less than 1.0 mA of current. The output
remains in a high impedance state regardless of the state
of the OE input.
