EP1K100FC484-3

The EP1K100FC484-3 is an ACEX-1K family Field Programmable Gate Array (FPGA) optimized for system-on-a-programmable-chip integration and cost-sensitive embedded designs. It combines a logic array, dedicated embedded array blocks (EABs) and flexible I/O to address communications, SOPC integration and general-purpose logic tasks.

Key value comes from an integrated memory-rich architecture—providing approximately 49,152 bits of on-chip RAM and roughly 4,992 logic elements—together with up to 333 user I/O pins in a 484-ball BGA package for compact, surface-mount system designs.

Key Features

• Core Logic  Approximately 4,992 logic elements (LEs) and a maximum system gate count of 257,000, enabling medium-density programmable logic implementations.
• Embedded Memory (EAB)  Total RAM: 49,152 bits implemented across 12 EABs (4,096 bits per EAB), including dual-port capability and up to 16-bit width per EAB for efficient on-chip storage and data buffering.
• I/O and Interface Flexibility  Up to 333 user I/O pins with MultiVolt I/O options (drive/receive 2.5-V, 3.3-V, or 5.0-V devices as described in the family datasheet) and individual pin options such as tri-state enable and open-drain configurations.
• Clocking and Dedicated Chains  Low-skew, built-in clock distribution with up to six global clock signals and dedicated carry and cascade chains for high-speed arithmetic and high-fan-in logic implementation.
• Configuration and Test  Supports in-circuit reconfigurability (ICR) and JTAG boundary-scan per IEEE 1149.1 for device programming and board-level testability without consuming user logic.
• Package & Mounting  Surface-mount 484-BBGA package (supplier device package listed as 484-FBGA 23×23) for high-density board layouts.
• Power & Supply  Specified operating supply range of 2.375 V to 2.625 V (internal recommended 2.5 V operation noted in family documentation).
• Commercial Temperature Grade  Rated for commercial operation from 0 °C to 70 °C; RoHS compliant.

Typical Applications

• Communications Equipment  Use as programmable logic for protocol handling, packet processing and interface bridging where memory-rich blocks and high I/O counts are required.
• System-on-a-Programmable-Chip (SOPC) Integration  Embed controllers, peripherals and custom logic into a single device to reduce BOM and board area for medium-density embedded systems.
• Custom Logic and Glue  Implement glue logic, state machines and data-path functions that require dedicated carry/cascade resources and multiple global clocks.
• PCI-Compatible Interfaces  Family-level documentation indicates compliance with PCI Local Bus Specification Revision 2.2 for 3.3-V operation at 33 MHz or 66 MHz, enabling use in PCI-interface designs (see device family datasheet for compatibility details).

Unique Advantages

• Balanced Logic and Memory  Large on-chip RAM (49,152 bits) combined with nearly 5k logic elements simplifies designs that need embedded data storage alongside combinational and sequential logic.
• High I/O Density  Up to 333 user I/O pins in a 484-BBGA footprint supports complex board-level connectivity without external multiplexing.
• Flexible I/O Standards  MultiVolt I/O capability (as described in family documentation) enables direct interfacing to a range of legacy and modern voltage domains.
• Built-in Test and Reconfiguration  JTAG boundary-scan and in-circuit reconfigurability streamline manufacturing test and field updates without consuming user logic resources.
• Dedicated Arithmetic and Routing Resources  Carry and cascade chains plus FastTrack interconnect options simplify implementation of fast adders, counters and wide combinational functions.
