The AT17F16A is packaged in the 8-pad LAP and 20-lead PLCC (Table 1). The AT17F16A uses a simple serial-access procedure to configure one or more FPGA devices. The AT17F16A can be programmed with industry-standard programmers, the Atmel ATDH2200E Programming Kit, or the Atmel ATDH2225 ISP Cable. Table 1.

Pin Description DATA(1) Three-state DATA output for FPGA Configuration. Open-collector bi-directional pin for configuration programming. DCLK(1) Three-state Clock. Functions as an input when the Configurator is in programming mode (i.e. SER_EN is Low) and as an output during FPGA configuration. PAGE_EN(2) Enable Page Download Mode Input. When PAGE_EN is high the configuration download address space is partitioned into four equal pages. This gives users the ability to easily store and retrieve multiple configuration bitstreams from a single configuration device. This input works in conjunction with the PAGESEL inputs. PAGE_EN must be remain low if paging is not desired. When SER_EN is Low (ISP mode) this pin has no effect. PAGESEL[1:0](2) Page Select Inputs. Used to determine which of the four memory pages are targeted during a serial configuration download. The address space for each of the pages is shown in Table 1-2. When SER_EN is Low (ISP mode) these pins have no effect. RESET/OE(1) 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 nCS Low) enables the data output driver. nCS 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 nCS 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). GND Ground. A 0.2μF decoupling capacitor between VCC and GND is recommended. nCASC Cascade Select Output (when SER_EN is High). This output goes Low when the internal address counter has reached its maximum value. If the PAGE_EN input is set High, the maximum value is the highest address in the selected partition. The PAGESEL[1:0] inputs are used to make the four partition selections. If the PAGE_EN input is set Low, the device is not partitioned and the address maximum value is the highest address in the device (Table 1-2). In a daisy chain of the AT17FxxxA Series devices, the nCASC pin of one device must be connected to the nCS input of the next device in the chain. It will stay Low as long as nCS is Low and OE is High. It will then follow nCS until OE goes Low; thereafter, nCASC will stay High until the entire EEPROM is read again. A2(1) Device Selection Input, (when SER_EN Low). The input is used to enable (or chip select) the device during programming (i.e., when SER_EN is Low). Refer to the Atmel AT17FxxxA Programming Specification available at www.atmel.com for additional details. READY Open Collector Reset State Indicator. Driven Low during power-up reset, released when power-up is complete. (recommended 4.7k pull-up on this pin if used). SER_EN(1) Serial Enable Input. Must remain High during FPGA configuration operations. Bringing SER_EN Low enables the 2-Wire Serial Programming Mode. For non-ISP applications, SER_EN should be tied to VCC.

Device Description The control signals for the configuration memory device (nCS, RESET/OE and DCLK) interface directly with the FPGA device control signals. All FPGA devices can control the entire configuration process and retrieve data from the configuration device without requiring an external intelligent controller. The RESET/OE and nCS 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 nCS pin also controls the output of the AT17F16A. If nCS 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 High, the counter and the DATA output pin are enabled. When RESET/OE is driven Low again, the address counter is reset and the DATA output pin is tri-stated, regardless of the state of nCS. When the configurator has driven out all of its data and nCASC 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. 4. FPGA Master Serial Mode Summary The I/O and logic functions of any SRAM-based FPGA are established by a configuration 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 AT17F16A Serial Configuration PROM has been designed for compatibility with the Master Serial mode. This document discusses the configurator used in Altera applications. 5. Control of Configuration Most connections between the FPGA device and the AT17FxxA Serial Configurator PROM are simple and selfexplanatory. 6. The DATA output of the AT17F16A Configurator drives DIN of the FPGA devices. The DCLK output of the AT17F16A device drives the DCLK input data of the FPGA. The nCASC output of a AT17F16A Configurator drives the nCS input of the next Configurator in a cascade chain of configurator devices. SER_EN must be at logic High level (internal pull-up resistor 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 REMAIN Low if download paging is not desired. 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, (Table 1-2). 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 nCASC output Low and disables its DATA line driver. The second configurator recognizes the Low level on its nCS 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. AT17F16A [DATASHEET] Atmel-3474F-CNFG-AT17F16A-Datasheet_012015 5 7. 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 AT17F16A is read/write at 3.3V nominal. Refer to the AT17F(A) Programming Specification available on www.atmel.com for more programming details. AT17F16A is supported by the Atmel ATDH2200 programming system along with many third party programmers. 8. Standby Mode The AT17F16A enters a low-power standby mode whenever SER_EN is High and nCS is asserted High. In this mode, the AT17F16A typically consumes less than 3mA of current at 3.3V. The output remains in a highimpedance state regardless of the state of the OE input. 6 AT17F16A [DATASHEET] Atmel-3474F-CNFG-AT17F16A-Datasheet_012015 9.
