EP20K400EBC652-2

The EP20K400EBC652-2 is an APEX-20KE family field programmable gate array (FPGA) IC from Altera, provided in a 652-ball BGA surface-mount package. It delivers mid-range programmable logic capacity together with substantial I/O count and on-chip memory for configurable digital designs.

With 16,640 logic elements arranged across 1,664 logic blocks, 488 I/O pins, and approximately 0.213 Mbits of embedded RAM, this commercial-grade FPGA targets applications that require flexible logic integration, moderate embedded memory, and a dense I/O footprint. The device operates from a 1.71 V to 1.89 V core supply and is specified for 0 °C to 85 °C operation.

Key Features

• Core Logic  16,640 logic elements implemented across 1,664 logic blocks, providing programmable resources for custom digital functions.
• Embedded Memory  Approximately 0.213 Mbits of on-chip RAM (212,992 bits) to support buffering, state storage, and look‑up table needs within designs.
• I/O Density  488 device I/O pins to support high-pin-count interfacing and multi‑channel connectivity in compact board layouts.
• Gate Equivalent  Approximately 1,052,000 gates, reflecting the device’s overall logic capacity for medium‑complexity designs.
• Power and Operating Range  Core voltage supply range of 1.71 V to 1.89 V and commercial operating temperature from 0 °C to 85 °C.
• Package and Assembly  652-ball BGA package (45 mm × 45 mm) designed for surface-mount assembly on modern PCBs.
• Compliance  RoHS compliant, meeting common regulatory requirements for lead‑free assembly.

Typical Applications

• Embedded Systems  Programmable logic for embedded controllers and custom I/O handling where up to 488 external signals must be managed.
• Data Interface and I/O Aggregation  Consolidating multiple digital interfaces and protocol bridges using the device’s high I/O count and programmable logic resources.
• Custom Digital Acceleration  Implementing application‑specific processing blocks or hardware accelerators that benefit from on‑chip RAM and substantial logic density.

Unique Advantages

• High Logic Capacity: 16,640 logic elements provide room for medium‑complexity designs without moving to a larger device family.
• Significant I/O Count: 488 I/O pins enable dense external connectivity and reduce the need for external multiplexing or additional interface components.
• On‑Chip Memory: Approximately 0.213 Mbits of embedded RAM supports buffering and local data storage, simplifying board-level memory requirements.
• Compact BGA Packaging: 652-BGA (45 × 45 mm) package supports surface-mount assembly and helps keep board area efficient for complex designs.
• Commercial‑Grade Specification: Rated for 0 °C to 85 °C operation and RoHS compliant for mainstream consumer and industrial electronics applications.
