LAV-AT-X70-1LFG1156I

The LAV-AT-X70-1LFG1156I is an Avant™-X FPGA device from Lattice Semiconductor, implemented in a 1156-ball FCBGA package. It leverages the Avant platform architecture, which includes programmable functional unit blocks, on-chip memory and DSP resources, and a comprehensive clocking and I/O structure described in the platform datasheet.

Targeted for industrial applications, this FPGA combines a large programmable fabric with substantial embedded memory and a high I/O count to address designs that require integration of logic, memory interfaces and high-speed I/O within a compact surface-mount package.

Key Features

• Programmable Logic — Approximately 637,000 logic elements enable complex logic integration and large-scale custom processing blocks.
• Embedded Memory — Approximately 4.24 Mbits of on-chip RAM (4,239,360 total RAM bits) supporting single, dual and pseudo-dual port modes, FIFO modes and memory cascading as described in the Avant platform documentation.
• High I/O Density — 554 user I/O pins provide extensive external connectivity for peripheral interfaces and high-pin-count designs.
• Clocking and Timing — Platform-level clock architecture includes on-chip oscillator, PLL, global and regional clocks, edge clocks, PHYCLK, clock synchronizers/dividers, dynamic clock select/control and DLL delay functionality.
• High-speed Interfaces — Avant platform documentation details SERDES/PMA blocks, multi-protocol PCS and PHY integration as well as DDR PHY support for external memory interfaces.
• Programmable I/O and Memory Peripherals — Programmable I/O cell (PIC) features, sysI/O banking and sysMEM capabilities (including RAM initialization, ROM operation and memory output reset) are provided by the platform.
• Device Configuration and Reliability — Device configuration options include JTAG and platform-level SEU handling and trace ID features as outlined in the datasheet.
• Industrial Grade and Environmental — Industrial-grade device with an operating temperature range of −40 °C to 100 °C and RoHS compliance.
• Package and Mounting — Surface-mount 1156-BBGA / 1156-FCBGA package (supplier device package: 1156-FCBGA, 35 × 35 mm) for compact board-level integration.
• Voltage Supply — Listed voltage supply value: 820 mV (specified range: 820 mV to 820 mV).

Typical Applications

• Industrial Control and Automation — Programmable logic density and industrial temperature rating support control systems, machine automation and I/O-intensive sensor aggregation.
• High-speed Data Interfaces — SERDES, DDR PHY and multi-protocol PHY/PCS capabilities make the device suitable for designs that require robust external memory interfaces and high-speed serial links.
• Embedded Processing and Signal Conditioning — Large logic capacity and on-chip DSP/memory resources enable data path acceleration, protocol handling and embedded pre-processing tasks.

Unique Advantages

• Large Programmable Fabric: ~637,000 logic elements provide headroom for complex designs and multiple concurrent functions on a single device.
• Substantial On-Chip Memory: Approximately 4.24 Mbits of embedded RAM supports lookup tables, buffering and FIFO implementations without relying exclusively on external memory.
• High I/O Count: 554 I/Os reduce the need for external I/O expanders and simplify board-level routing for dense peripheral interfaces.
• Comprehensive Clocking Architecture: Built-in oscillators, PLLs and dynamic clock controls from the Avant platform enable flexible timing domains and clock management inside the FPGA.
• Industrial-ready Thermal Range: −40 °C to 100 °C operating range supports deployment in demanding environments.
• Compact Surface-Mount Package: 1156-FCBGA (35 × 35 mm) delivers high integration density in a board-friendly surface-mount form factor.
