LAV-AT-E50-1CBG484C

The LAV-AT-E50-1CBG484C is an Avant™-E series Field Programmable Gate Array (FPGA) IC from Lattice Semiconductor Corporation. It implements the Avant platform architecture with programmable functional units, on-chip memory and DSP capabilities suited for designs that require a large number of logic elements, extensive on-chip RAM, and substantial I/O connectivity.

This device targets commercial-grade applications and offers a combination of programmable logic (409,000 logic element cells), approximately 2.7 Mbits of embedded memory, and 329 I/O pins in a 484-FCCSP (19×19) BGA package—delivering a balance of integration, I/O density, and configurability.

Key Features

• Core Architecture Avant platform architecture with Programmable Functional Unit (PFU) blocks and slice-based logic resources as described in the Avant documentation.
• Logic Capacity 409,000 logic element cells to implement complex custom logic and system functions.
• Embedded Memory Approximately 2.7 Mbits of on-chip RAM (2,723,840 bits) with sysMEM features including RAM initialization, ROM operation, memory cascading, and single/dual/pseudo-dual port and FIFO modes.
• Processing and DSP Platform includes sysDSP blocks for dedicated signal processing capabilities (architectural details and integration provided by the Avant platform overview).
• I/O and Interfaces 329 I/O pins with programmable I/O (PIO) cells, banking schemes and supported sysI/O standards. Programmable I/O cell (PIC) functionality includes input, output and tri-state register blocks.
• High-Speed Interfaces Platform-level support for SERDES, PCS, SERDES/PMA blocks, multi-protocol PCS (MPPCS) and multi-protocol PHY (MPPHY) integration, and DDR memory support with DDRPHY and DQS grouping as described in the Avant platform documentation.
• Clocking and Timing Comprehensive clocking structure including on-chip oscillator, PLL, global/regional/edge/PHY clocks, clock synchronizers/dividers, dynamic clock select/control and DLL delay (DLLDEL).
• Configuration and Reliability Device configuration options include enhanced configuration modes, JTAG support and Single Event Upset (SEU) handling mechanisms discussed in the platform overview.
• Package and Mounting 484-ball FCCSP BGA package (484-FCCSP, 19×19) for surface mount assembly; RoHS compliant.
• Electrical and Environmental Specified supply voltage 820 mV and commercial operating temperature range 0 °C to 85 °C.

Typical Applications

• Memory interface controllers — Leverages DDR memory support and DDRPHY features for designs that require on-board DRAM interfacing and DQS grouping control.
• High-speed serial connectivity — Utilizes SERDES/PMA and PCS capabilities for designs needing multi-protocol serial links and high-speed PHY integration.
• Signal processing accelerators — Employs sysDSP blocks and abundant logic elements for embedded DSP functions and custom data-path implementation.
• Custom I/O bridging and protocol conversion — Programmable I/O cells and a large I/O count enable flexible interfacing between disparate peripherals and buses.

Unique Advantages

• High logic density: 409,000 logic element cells provide capacity for complex control, protocol handling and custom compute functions without external ASICs.
• Substantial on-chip memory: Approximately 2.7 Mbits of embedded RAM with versatile sysMEM modes reduces dependence on external memory for many designs.
• Rich I/O and PHY support: 329 I/O pins combined with SERDES, PCS and DDRPHY support enables high-bandwidth connectivity and flexible interface implementations.
• Comprehensive clocking: On-chip oscillator, PLLs and multiple clock domains support complex timing architectures and dynamic clock control.
• Commercial-grade reliability and compliance: RoHS compliant and specified for 0 °C to 85 °C operation for mainstream commercial applications.
