Support Device ATFS05 ATFS10 ATFS40 Advance Information
Description
The FPSLIC Support Devices provide an easy-to-use, cost-effective configuration memory for programming Field Programmable System Level Integrated Circuits by using a simple serial-access procedure to configure one or more FPSLIC devices. See Table 1 for a list of supported FPSLIC devices. The FPSLIC Support Device can be programmed with industry-standard programmers, Atmel's ATDH2200E Programming Kit or Atmel's ATDH2225 ISP Cable.

DATA
Device Description
The control signals for the FPSLIC Support Device (CE, RESET/OE and CCLK) interface directly with the FPSLIC control signals. All FPSLIC devices can control the entire configuration process and retrieve data from the FPSLIC Support Device without requiring an external intelligent controller. 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 EEPROM resets its address counter and tri-states its DATA pin. The CE pin also controls the output of the FPSLIC Support Device. 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 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 CE. When the FPSLIC Support Device has driven out all of its data and CEO is driven Low, the device tri-states the DATA pin to avoid contention with other FPSLIC Support Devices. Upon power-up, the address counter is automatically reset.

Pin Description
8 LAP Pin 1 2 3 Name DATA CLK RESET/OE I/O I/O I I Description Tri-state DATA output for configuration. Open-collector bi-directional pin for programming. Clock input. Used to increment the internal address and bit counter for reading and programming. 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. 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). Ground pin. A 0.2 F decoupling capacitor between VCC and GND is recommended. I 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 pull-down resistor. Serial enable must be held High during FPSLIC loading operations. Bringing SER_EN Low enables the 2-wire Serial Programming Mode. For non-ISP applications, SER_EN should be tied to VCC. +3.3V power supply pin

FPSLIC Master Serial Mode Summary
The I/O and logic functions of the FPSLIC devices are established by a configuration program. The program is loaded either automatically upon power-up, or on command, depending on the state of the mode pins. In Master Mode, the FPSLIC automatically loads the configuration program from an external memory. The FPSLIC Support Device has been designed for compatibility with the Master Mode. Most connections between the FPSLIC device and the FPSLIC Support Device are simple and self-explanatory: * * * The DATA output of the FPSLIC Support Device drives DIN of the FPSLIC devices. The master FPSLIC CCLK output drives the CLK input of the FPSLIC Support Device. SER_EN must be connected to VCC (except during ISP).
Control of Configuration
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 FPSLIC Support Device enters a low-power standby mode whenever CE is asserted High. In this mode, the ATFS05 consumes less than 50 A of current at 3.3V. The output remains in a high-impedance state regardless of the state of the OE input.

The FPSLIC's bi-directional CON pin drives the CE input of the FPSLIC Support Device, while the RESET/OE input is driven by the FPSLIC's bi-directional INIT pin. This connection works under all normal circumstances, even when the user aborts the configuration before CON has gone High. A Low level on the RESET/OE input, during FPSLIC reset, clears the FPSLIC Support Device's internal address pointer so that the reconfiguration starts at the beginning. The spare memory can be accessed by in-system programming the ATFS through a two-wire serial interface built in the FPSLIC device.
