SameFrame Pin-Out Example of EPF10K30AFC484-1

Package layout demonstrates how devices in the FLEX 10K family share a consistent ball grid structure across different package sizes. A printed circuit board footprint designed for a 484 pin FineLine BGA package supports devices with different I/O counts by maintaining the same outer ball positions. The diagram compares a 256 pin FineLine BGA device and a 484 pin FineLine BGA device, where the smaller package uses a reduced number of active connections while keeping alignment with the same board layout. This arrangement allows circuit boards designed for the larger package to accommodate smaller versions of the device when fewer input or output signals or logic resources are required.

Device Block Diagram of EPF10K30AFC484-1

Internal layout arranges programmable logic across a grid of Logic Array Blocks that contain multiple logic elements used to build digital circuits. Embedded Array Blocks appear within the array and provide dedicated memory resources that store data during device operation. Horizontal and vertical routing channels labeled as row and column interconnects form the internal signal network that links the logic blocks and memory regions. Input and output elements are positioned around the outer edges of the device, creating the electrical interface between internal logic and external pins. Local interconnect paths inside each logic array block allow nearby logic elements to exchange signals quickly, while the larger routing structure distributes signals across the entire programmable array.

Embedded Array Block of EPF10K30AFC484-1

Memory structure inside the programmable array contains an Embedded Array Block that provides dedicated storage within the FPGA fabric. The block supports configurable memory sizes including 256 × 8, 512 × 4, 1,024 × 2, and 2,048 × 1, allowing flexible data width and depth arrangements depending on the design. Data input, data output, address selection, and write enable paths connect the memory cell to surrounding logic through internal registers and control multiplexers. Local interconnect lines route signals from nearby logic array blocks directly into the memory interface, while row and column interconnect channels link the block to the wider routing network across the device. Dedicated input paths and global control signals manage timing and synchronization so stored data can be accessed by programmable logic elements within the FPGA.
