OR2C15A4S208-DB

The OR2C15A4S208-DB is a Field Programmable Gate Array (FPGA) IC from Lattice Semiconductor Corporation’s ORCA™2 family. It provides a moderate-density programmable logic fabric with 1,600 logic elements, 171 user I/Os and 25,600 bits of on-chip RAM.

Packaged in a 208-BFQFP surface-mount package and specified for commercial operation (0 °C to 70 °C) with a 4.75 V to 5.25 V supply, this device targets commercial embedded designs that require integrated logic, I/O count, and on-chip memory in a compact form factor.

Key Features

• Core Logic  Approximately 1,600 logic elements providing programmable combinational and sequential resources for custom logic implementation.
• Gate Density  Around 44,200 equivalent gates to support a range of medium-complexity logic functions and control paths.
• Embedded Memory  25,600 total RAM bits of on-chip memory (approximately 0.0256 Mbits) for distributed data buffering and small lookup tables.
• I/O  171 user I/O pins to support multiple external interfaces and peripheral connections within a single device.
• Power  Single-supply operation from 4.75 V to 5.25 V, simplifying system power supply requirements for 5 V-based designs.
• Package & Mounting  208-BFQFP surface-mount package; supplier device package listed as 208-SQFP (28 × 28) for board-level integration.
• Operating Range  Commercial grade operation from 0 °C to 70 °C, suitable for standard commercial environments.
• Environmental Compliance  RoHS-compliant construction for regulatory and manufacturing consistency.

Typical Applications

• Commercial Embedded Systems  Leverage the device’s 1,600 logic elements and 171 I/Os to implement control, glue logic, and custom peripheral interfaces in commercial products.
• Interface and I/O Bridging  Use the high I/O count to consolidate multiple external signals and manage protocol translation or signal routing on a single FPGA.
• Prototyping and Development  Compact package and moderate logic density make this FPGA suitable for proof-of-concept and development boards targeting commercial-temperature designs.

Unique Advantages

• Balanced Logic Density:  1,600 logic elements and ~44,200 gates provide a practical balance for medium-complexity functions without over-provisioning.
• High I/O Count:  171 user I/Os enable integration of multiple peripherals and external devices, reducing the need for additional I/O expanders.
• On-Chip Memory:  25,600 bits of embedded RAM allow localized buffering and small lookup implementations, simplifying board-level memory requirements.
• Standard 5 V Supply:  Operation from 4.75 V to 5.25 V aligns with many legacy and commercial system power rails for straightforward integration.
• Compact Surface-Mount Package:  208-BFQFP in a 28 × 28mm SQFP footprint supports dense PCB layouts while maintaining accessible pinout for prototyping and production.
• RoHS Compliant:  Built to meet environmental compliance expectations for modern manufacturing processes.
