EPF10K30ATI144-3

EPF10K30ATI144-3 is a CPLD (Complex Programmable Logic Device) from Altera’s EPF10K30 family. It provides about 10K equivalent gates organized into macrocells that pair combinational logic with a D-type flip-flop, enabling both combinational and sequential logic in a compact device. The “ATI144” suffix indicates a 144-pin package (typically a TQFP/PLCC-style). The “-3” is the speed grade (faster variant within the family).
Key points:
- Medium-density CPLD suitable for glue logic, small state machines, decoders, and peripheral interface logic.
- Configurable I/O blocks and internal routing resources for flexible interconnects.
- Includes programmable clocking/control resources for synchronous designs.
- Designed to be programmed via vendor tools from HDL (Verilog/VHDL) or schematic descriptions.
Typical use: replace discrete logic with a single device for deterministic timing, rapid development, and moderate logic needs in embedded or board-support logic. Note: EPF10K30 is older technology; toolchains and support may be legacy-oriented.

EPF10K30ATI144-3 features (concise):
- Actel (Microsemi) flash-based FPGA with about 10K system gates
- 144-pin TQFP (ATI144) package
- -3 speed grade (moderate max clock; tens of MHz range typical)
- Nonvolatile configuration via on-chip flash; instant-on without external PROM
- In-system Programmability via JTAG; easy reconfiguration
- Rich logic resources: LUT/flip-flop logic, distributed RAM blocks, and shift registers
- Flexible I/O blocks with multiple I/O standards and good fan-out
- Internal routing/clock resources for versatile designs
- Low-power operation with standby/low-power modes
- Security features: bitstream/IP protection
- Broad HDL support (Verilog/VHDL) and standard FPGA design flows
Note: exact I/O count and internal block sizes vary by revision; this summarizes typical capabilities for the EPF10K30ATI144-3 family.

EPF10K30ATI144-3 uses a 144-pin TQFP (Plastic Quad Flat Pack) package.

There isn’t an exact one-to-one cross reference for EPF10K30ATI144-3. It’s an old Actel EPLD (~10K gates, 144-pin). For substitutes, specify target vendor and specs (gates, I/O, speed, packaging). Closest families to evaluate: Microsemi IGLOO2/Fusion devices, Xilinx CPLDs (XC2C/XL2 series), and Lattice ispMACH/ispLSI CPLDs. Providing gate count, I/O requirements, and packaging will yield precise part numbers.
