Overview of EP20K400GC655-2 – APEX-20KC Field Programmable Gate Array, 655-BCPGA
The EP20K400GC655-2 is an APEX-20KC Field Programmable Gate Array (FPGA) IC from Altera. It provides a balance of programmable logic capacity, embedded memory, and a high I/O count in a 655-BCPGA package for commercial-grade designs.
This device is suited for designs that require up to 16,640 logic elements, approximately 0.213 Mbits of embedded RAM, and up to 488 general-purpose I/O in a through-hole 655-CPGA (62.48 × 62.48 mm) footprint. It operates on a 1.71 V to 1.89 V supply and within a 0 °C to 85 °C commercial temperature range.
Key Features
- Core Logic Provides 16,640 logic elements, enabling complex programmable logic implementations and consolidation of custom digital functions.
- Gate Density Approximately 1.05 million gates of programmable logic to support sizable combinational and sequential designs.
- Embedded Memory Total on-chip RAM of 212,992 bits (approximately 0.213 Mbits) for local buffering, state storage, and small data structures.
- I/O Resources Up to 488 I/O pins to support dense peripheral interfacing, wide parallel buses, or multiple I/O domains.
- Package & Mounting 655-BCPGA package; supplier device package listed as 655-CPGA (62.48 × 62.48 mm). Designed for through-hole mounting.
- Power Nominal operating supply range of 1.71 V to 1.89 V to match targeted system voltage rails.
- Temperature & Grade Commercial grade operation with an ambient temperature range of 0 °C to 85 °C.
- Environmental Compliance RoHS compliant.
Typical Applications
- System Prototyping and Validation Use the programmable logic capacity and ample I/O to prototype custom logic, bus interfaces, and control fabrics.
- I/O-Intensive Interfaces Ideal for bridging or aggregating multiple parallel interfaces where up to 488 I/O are required for peripherals and external devices.
- Embedded Control and State Machines Leverage the device’s logic elements and on-chip RAM for finite state machines, real-time control logic, and sequence handling.
- Logic Consolidation Replace multiple discrete logic components by migrating functions into programmable logic using the device’s gate and element capacity.
Unique Advantages
- High Logic Capacity: 16,640 logic elements enable integration of complex custom digital functions into a single FPGA.
- Substantial On-Chip Memory: Approximately 0.213 Mbits of embedded RAM for buffering, small look-up tables, and local data storage without external memory.
- Large I/O Count: Up to 488 I/O pins support dense peripheral connectivity and wide parallel interfaces, reducing the need for external I/O expanders.
- Robust Gate Count: Around 1.05 million gates provide the logical capacity necessary for medium-to-large designs.
- Commercial Temperature Range: Rated for 0 °C to 85 °C, suitable for mainstream embedded and electronic applications.
- RoHS Compliant: Meets common environmental requirements for lead-free assembly and regulatory preference.
