9 / 28 page  AT6000(LV) Series 9 The devices can be partially reconfigured while in opera- tion. Portions of the device not being modified remain operational during reconfiguration. Simultaneous configu- ration of more than one device is also possible. Full configuration takes as little as a millisecond, partial configu- ration is even faster. Refer to the Pin Function Description section following for a brief summary of the pins used in configuration. For more information about configuration, refer to the AT6000 Series Configuration data sheet. Pin Function Description This section provides abbreviated descriptions of the vari- ous AT6000 Series pins. For more complete descriptions, refer to the AT6000 Series Configuration data sheet. Pinout tables for the AT6000 series of devices follow. Power Pins V CC, VDD, GND, VSS V CC and GND are the I/O supply pins, VDD and VSS are the internal logic supply pins. V CC and VDD should be tied to the same trace on the printed circuit board. GND and V SS should be tied to the same trace on the printed circuit board. Input/Output Pins All I/O pins can be used in the same way (refer to the I/O section of the architecture description). Some I/O pins are dual-function pins used during configuration of the array. When not being used for configuration, dual-function I/Os are fully functional as normal I/O pins. On initial power-up, all I/Os are configured as TTL inputs with a pull-up. Dedicated Timing and Control Pins CON Configuration-in-process pin. After power-up, CON stay- sLow until power-up initialization is complete, at which time CON is then released. CON is an open collector signal. After power-up initialization, forcing CON low begins the configuration process. CS Configuration enable pin. All configuration pins are ignored if CS is high. CS must be held low throughout the configu- ration process. CS is a TTL input pin. M0, M1, M2 Configuration mode pins are used to determine the config- uration mode. All three are TTL input pins. CCLK Configuration clock pin. CCLK is a TTL input or a CMOS output depending on the mode of operation. In modes 1, 2, 3, and 6 it is an input. In modes 4 and 5 it is an output with a typical frequency of 1 MHz. In all modes, the rising edge of the CCLK signal is used to sample inputs and change outputs. CLOCK External logic source used to drive the internal global clock line. Registers toggle on the rising edge of CLOCK. The CLOCK signal is neither used nor affected by the configu- ration modes. It is always a TTL input. RESET Array register asynchronous reset. RESET drives the inter- nal global reset. The RESET signal is neither used nor affected by the configuration modes. It is always a TTL input. Dual-function Pins When CON is high, dual-function I/O pins act as device I/Os; when CON is low, dual-function pins are used as con- figuration control or data signals as determined by the configuration modes. Care must be taken when using these pins to ensure that configuration activity does not interfere with other circuitry connected to these pins in the application. D0 or I/O Serial configuration modes use D0 as the serial data input pin. Parallel configuration modes use D0 as the least-sig- ni fic a n t bi t. Inpu t d a ta mus t mee t s e tu p a nd hol d requirements with respect to the rising edge of CCLK. D0 is a TTL input during configuration. D1 to D7 or I/O Parallel configuration modes use these pins as inputs. Serial configuration modes do not use them. Data must meet setup and hold requirements with respect to the rising edge of CCLK. D1 - D7 are TTL inputs during configuration. A0 to A16 or I/O During configuration in modes 1, 2 and 5, these pins are CMOS outputs and act as the address pins for a parallel EPROM. A0 - A16 eliminates the need for an external address counter when using an external parallel nonvolatile |
