1. Description
The AT18F Series of JTAG In-System Programmable Configuration PROMs (Configurators) provide an easy-to-use, cost-effective configuration memory for Field
Programmable Gate Arrays. The AT18F Series device is packaged in a 20-lead
TSSOP. The AT18F Series Configurator uses a simple serial-access procedure to
configure one or more FPGA devices.
The AT18F Series Configurators can be programmed with Atmel or industry-standard,
third-party, stand-alone programmers such as BP, Data I/O, Hi-Lo, etc.

4. Device Description
The download interface of the configuration memory will directly communicate with the FPGA
through the interface-control signals (CLK, RESET/OE, CE) to initialize and terminate configuration. All FPGA devices in the master serial mode can control the entire configuration process to
receive data from the configuration device without requiring an external intelligent controller.
When FPGA devices are used in slave serial mode, an external clock signal can be applied to
the CLK pin of an AT18F series device as a configuration loading clock. Multiple FPGAs that are
setup in Master Serial and Slave Serial modes can also be used to control the configuration process to obtain data from a single configurator or cascaded configurators. Please contact Atmel
at [email protected] for detailed descriptions.
The CF pin is used as an optional input pin for the JTAG CONFIG instruction to initialize the
FPGA configuration without requiring powering down the device. The RESET/OE and CE pins
control the tri-state buffer on the DATA output pin and enable the address counter. When
RESET/OE is driven Low, the configuration device resets its address counter and tri-states its
DATA pin. The CE pin also controls the output of the AT18F Series Configurator. If CE is held
High after the RESET/OE reset pulse, the counter is reset and the DATA output pin is tri-stated.
When the configurator has driven out all of its data and CEO is driven Low, the device tri-states
the DATA pin to avoid contention with other configurators. Upon power-up, the address counter
is automatically reset.

5. Programming
AT18Fxx devices are in-system programmable (ISP) devices utilizing the 4-pin JTAG protocol.
This capability eliminates package handling normally required for programming and facilitates
rapid design iterations and field changes.
Atmel provides ISP hardware and software to allow programming of the AT18Fxx via the PC.
ISP is performed by using either a download cable or a comparable 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 JCPS Software. Conversion to other ATE
tester format beside SVF is also possible
AT18Fxx devices can also be programmed using standard third-party programmers such as BP,
DataI/O, Hi-Lo, etc. Factory-preprogrammed devices, as required by customers, are also available for certain ordering quantities.
Contact your local Atmel representatives or Atmel PLD applications for details.
5.1
JTAG-BST Overview
The JTAG boundary-scan testing is controlled by the Test Access Port (TAP) controller in the
AT18F series. The boundary-scan technique involves the inclusion of a shift-register stage (contained in a boundary-scan cell) adjacent to each component so that signals at component
boundaries can be controlled and observed using scan testing principles. Each input pin and I/O
pin has its own boundary-scan cell (BSC) in order to support boundary-scan testing. The
AT18Fxx series does not currently include a Test Reset (TRST) input pin because the TAP controller is automatically reset at power-up. The six JTAG BST modes supported include:
SAMPLE/PRELOAD, EXTEST, BYPASS and IDCODE. BST on the AT18Fxx series is implemented using the Boundary-scan Definition Language (BSDL) described in the JTAG
specification (IEEE Standard 1149.1). Any third-party tool that supports the BSDL format can be
used to perform BST on the AT18Fxx series.
The AT18F series uses the four JTAG-standard I/O pins for In-System programming (ISP). The
AT18F series is programmable through the four JTAG pins using programming algorithm compatible with the IEEE JTAG Standard 1532. Programming is performed by using selectable
voltage levels of the programming signals from the JTAG ISP interface.
5.2
JTAG Boundary-scan Cell (BSC) Testing
The AT18F series has I/Os that contain boundary-scan cells (BSC) in order to support boundary-scan testing as described in detail by IEEE Standard 1149.1. Input to the capture register
chain is fed in from the TDI pin while the output is directed to the TDO pin. Capture registers are
used to capture active device data signals, to shift data in and out of the device and to load data
into the update registers. Control signals are generated internally by the JTAG TAP controller.

Pin Descriptions
DATA (D0)
Open-collector bi-directional data pin. This pin has an internal 20 KΩ pull-up resistor.
6.2
CLK
Clock input. Used to increment the internal address and bit counter for reading and programming. This pin has an internal 20 KΩ pull-up resistor.
6.3
RESET/OE
Output Enable (active High) and RESET (active Low). A Low level on RESET/OE resets both
the address and bit counters. A High level (with CE Low) enables the data output driver. This pin
has an internal 20 KΩ pull-up resistor.
6.4
CE
Chip Enable input (active Low). A Low level (with OE High) allows CLK to increment the address
counter and enables the data output driver. A High level on CE disables both the address and bit
counters and forces the device into a low-power standby mode. This pin has an internal 20 KΩ
pull-up resistor.
6.5
CF
Configuration Pulse (open-drain output). Allows JTAG CONFIG instruction to initiate FPGA configuration without powering down the FPGA. This is an open-drain output that is pulsed Low by
the JTAG CONFIG command.

AT18F010/002/040/080 [Preliminary]
6.6
CEO
Chip Enable Output for configuration download. This output goes Low when the internal address
counter of the device has reached its maximum value which signals that all configuration data is
being clocked out of the device. In a daisy chain of AT18F Series devices, the CEO pin of one
device must be connected to the CE input of the next device in the chain. It will stay Low as long
as CE is Low and OE is High. It will then follow CE until OE goes Low; thereafter, CEO will stay
High until the entire memory device is read again.
6.7
TMS
JTAG Mode Control Input. The state of TMS with the rising edge of TCK determines the state
transitions of the Test Access Port (TAP) controller. TMS has an internal 50 KΩ weak pull-up to
VCCJ to provide a logic 1 to the device.
6.8
TCK
JTAG Clock Input. This pin is the JTAG clock input to the TAP controller of the device.
6.9
TDI
JTAG Serial Data Input. This pin is the serial input to all JTAG instructions and data registers. An
internal 50 KΩ weak pull-up to VCCJ provides a logic 1 to the device.
6.10
TDO
JTAG Serial Data Output. This pin is the serial output to all JTAG instruction and data registers.
An internal 50 KΩ weak pull-up to VCCJ provides a logic 1 to the device if the pin is not driven.
6.11
VCCINT
+3.3V supply voltage for internal logic.

6.15
GND

7. Standby Mode
The AT18F Series Configurators enter a low-power standby mode whenever the JTAG mode is
inactive and CE is asserted High. In this mode, the AT18F Configurator consumes less than 1
mA of current at 3.3V. The output remains in a high-impedance state regardless of the state of
the OE input.
