The AT17 Series is packaged in the popular 8-lead LAP, 20-lead PLCC, 44-lead PLCC and the 44-lead TQFP. The AT17 Series family uses a simple serial-access procedure to configure one or more FPGA devices. The user can select the polarity of the reset function by programming four EEPROM bytes. These devices support a write protection mode and a system- friendly READY pin, which signifies a “good” power level to the FPGA and can be used to ensure reliable system power-up. The AT17 Series Configurators can be programmed with industry-standard program- mers, Atmel’s ATDH2200E Programming System and Atmel’s ATDH2225 ISP Cable.1

AT17C/LV002Block Diagram Device Description The control signals for the configuration EEPROM (CE, RESET/OE and CCLK) inter- face directly with the FPGA device control signals. All FPGA devices can control the entire configuration process and retrieve data from the configuration EEPROM without requiring an external intelligent controller. The configuration EEPROM 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 High, the configuration EEPROM resets its address counter and tri-states its DATA pin. The CE pin also controls the output of the AT17 Series Configurator. If CE is held High after the RESET/OE reset pulse, the counter is disabled and the DATA output pin is tri-stated. When OE is subsequently driven Low, the counter and the DATA output pin are enabled. When RESET/OE is driven High again, the address counter is reset and the DATA output pin is tri-stated, regardless of the state of CE. 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. This is the default setting for the device. Since almost all FPGAs use RESET Low and OE High, this document will describe RESET/OE.

Used to protect portions of memory during programming. Disabled by default due to internal pull-down resistor. This input pin is not used during FPGA loading operations. 3 6 13 19 RESET/OE I Output Enable (active High) and RESET (active Low) when SER_EN is High. A Low level on RESET/OE resets both the address and bit counters. A High level (with CE Low) enables the data output driver. The logic polarity of this input is programmable as either RESET/OE or RESET/OE. For most applications, RESET should be programmed active Low. This document describes the pin as RESET/OE. 4 8 15 21 CE I Chip Enable input (active Low). A Low level (with OE High) allows DCLK 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. Note that this pin will not enable/disable the device in the 2-wire Serial Programming mode (SER_EN Low). 5 10 18 24 GND Ground pin. A 0.2 µF decoupling capacitor between VCC and GND is recommended. 6 14 21 27 CEO O Chip Enable Output (active Low). This output goes Low when the address counter has reached its maximum value. In a daisy chain of AT17 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 EEPROM is read again. A2 I Device selection input, A2. This is used to enable (or select) the device during programming (i.e., when SER_EN is Low). A2 has an internal pulldown resistor. – 15 23 29 READY(1) O Open collector reset state indicator. Driven Low during power-up reset, released when power-up is complete. (Recommend a 4.7 kΩ pull-up on this pin if used). 7 17 35 41 SER_EN I Serial enable must be held High during FPGA loading operations. Bringing SER_EN Low enables the 2-wire Serial Programming Mode. For non-ISP applications, SER_EN should be tied to VCC. 8 20 38 44 VCC +3.3V/+5V power supply pin.4 AT17C/LV002 2281D–12/01

AT17C/LV002FPGA Master Serial Mode Summary The I/O and logic functions of any SRAM-based FPGA are established by a configura- tion program. 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 configuration program from an external memory. The AT17 Serial Configuration EEPROM has been designed for compatibility with the Master Serial Mode. This document discusses the AT40K, AT40KAL and AT94KAL applications, as well as Xilinx applications. Control of Configuration Most connections between the FPGA device and the AT17 Serial EEPROM are simple and self-explanatory: • The DATA output of the AT17 Series Configurator drives DIN of the FPGA devices. • The master FPGA CCLK output drives the CLK input of the AT17 Series Configurator. • The CEO output of any AT17 Series Configurator drives the CE input of the next Configurator in a cascade chain of EEPROMs. • SER_EN must be connected to VCC (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. Cascading Serial Configuration EEPROMs For multiple FPGAs configured as a daisy-chain, or for FPGAs requiring larger configu- ration memories, cascaded Configurators provide additional memory. As 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. AT17 Series Reset Polarity The AT17 Series Configurator allows the user to program the reset polarity as either RESET/OE or RESET/OE. This feature is supported by industry-standard programmer algorithms. Programming Mode The programming mode is entered by bringing SER_EN Low. In this mode the chip can be programmed by the 2-wire serial bus. The programming is done at VCC supply only. Programming super voltages are generated inside the chip. The AT17C parts are read/write at 5V nominal. The AT17LV parts are read/write at 3.3V nominal. Standby Mode The AT17C/LV002 Series Configurator enters a low-power standby mode whenever CE is asserted High. In this mode, the Configurator consumes less than 0.5 mA of current at 5V. The output remains in a high-impedance state regardless of the state of the OE input.5 2281D–12/01

Example Circuits Figure 1. AT17 Series Device for Programming PSLI Devices Notes: 1. Reset polarity must be set to active Low. 2. Use of the optional READY pin is not available on the AT17C/LV65/128/256 devices. The FPGA CON/DONE output drives the CE input of the AT17 Series Configurator, while the RESET/OE input is driven by the FPGA INIT pin. This connection works under all normal circumstances, even when the user aborts the configuration before CON/DONE has gone High. A Low level on the RESET/OE input, during FPGA reset, clears the configurator’s inter- nal address pointer so that the reconfiguration starts at the beginning. Figure 2.

All current moves in switching devices with the proper selection of amp rating capability. I chose these to do a job that had to handle only 1/3 of it's rated capacity. So they were the perfect choice. To date they work as expected; perfectly.
