10 / 14 page IGLOO PLUS Device Family Overview 1- 6 v1.3 The FlashROM can be programmed via the JTAG programming interface, and its contents can be read back either through the JTAG programming interface or via direct FPGA core addressing. Note that the FlashROM can only be programmed from the JTAG interface and cannot be programmed from the internal logic array. The FlashROM is programmed as 8 banks of 128 bits; however, reading is performed on a byte-by- byte basis using a synchronous interface. A 7-bit address from the FPGA core defines which of the 8 banks and which of the 16 bytes within that bank are being read. The three most significant bits (MSBs) of the FlashROM address determine the bank, and the four least significant bits (LSBs) of the FlashROM address define the byte. The Actel IGLOO PLUS development software solutions, Libero® Integrated Design Environment (IDE) and Designer, have extensive support for the FlashROM. One such feature is auto-generation of sequential programming files for applications requiring a unique serial number in each part. Another feature allows the inclusion of static data for system version control. Data for the FlashROM can be generated quickly and easily using Actel Libero IDE and Designer software tools. Comprehensive programming file support is also included to allow for easy programming of large numbers of parts with differing FlashROM contents. SRAM and FIFO IGLOO PLUS devices (except AGLP030 devices) have embedded SRAM blocks along their north side. Each variable-aspect-ratio SRAM block is 4,608 bits in size. Available memory configurations are 256×18, 512×9, 1k×4, 2k×2, and 4k×1 bits. The individual blocks have independent read and write ports that can be configured with different bit widths on each port. For example, data can be sent through a 4-bit port and read as a single bitstream. The embedded SRAM blocks can be initialized via the device JTAG port (ROM emulation mode) using the UJTAG macro (except in AGLP030 devices). In addition, every SRAM block has an embedded FIFO control unit. The control unit allows the SRAM block to be configured as a synchronous FIFO without using additional core VersaTiles. The FIFO width and depth are programmable. The FIFO also features programmable Almost Empty (AEMPTY) and Almost Full (AFULL) flags in addition to the normal Empty and Full flags. The embedded FIFO control unit contains the counters necessary for generation of the read and write address pointers. The embedded SRAM/FIFO blocks can be cascaded to create larger configurations. PLL and CCC IGLOO PLUS devices provide designers with very flexible clock conditioning circuit (CCC) capabilities. Each member of the IGLOO PLUS family contains six CCCs. One CCC (center west side) has a PLL. The AGLP030 device does not have a PLL or CCCs; it contains only inputs to six globals. The six CCC blocks are located at the four corners and the centers of the east and west sides. One CCC (center west side) has a PLL. The four corner CCCs and the east CCC allow simple clock delay operations as well as clock spine access. The inputs of the six CCC blocks are accessible from the FPGA core or from one of several inputs located near the CCC that have dedicated connections to the CCC block. The CCC block has these key features: • Wide input frequency range (fIN_CCC) = 1.5 MHz up to 250 MHz • Output frequency range (fOUT_CCC) = 0.75 MHz up to 250 MHz • 2 programmable delay types for clock skew minimization • Clock frequency synthesis (for PLL only) Additional CCC specifications: • Internal phase shift = 0°, 90°, 180°, and 270°. Output phase shift depends on the output divider configuration (for PLL only). • Output duty cycle = 50% ± 1.5% or better (for PLL only) • Low output jitter: worst case < 2.5% × clock period peak-to-peak period jitter when single global network used (for PLL only) • Maximum acquisition time is 300 µs (for PLL only) |
