LAV-AT-E70-2CSG841C

The LAV-AT-E70-2CSG841C is an Avant™-E FPGA IC from Lattice Semiconductor Corporation designed for surface-mount applications in a 841-FCCSP (15×13) package. The device provides a high logic element count, substantial on-chip RAM, and a large I/O complement suitable for designs that require dense programmable logic and flexible I/O integration.

Architected on the Lattice Avant platform, the device implements programmable functional unit (PFU) blocks, configurable routing and clocking structures, and integrated memory and DSP resources as described in the Avant platform overview.

Key Features

• Logic Capacity — 637,000 logic element cells, enabling complex programmable logic implementations.
• Embedded Memory — Approximately 4.24 Mbits of on-chip RAM (4,239,360 total RAM bits) for large data buffering, FIFOs, and local storage.
• I/O Density — 502 user I/Os to support wide bus interfaces and high pin-count peripherals.
• Package & Mounting — 841-BGA / FCCSPBGA package (supplier device package: 841-FCCSP, 15×13) with surface-mount mounting for compact board designs.
• Supply and Temperature — Specified supply voltage at 820 mV and commercial operating temperature range of 0 °C to 85 °C.
• Platform Architecture — Built on the Avant platform with PFU blocks, slices, and configurable routing for application-specific datapaths and control logic.
• Clocking and Timing — On-chip oscillator, PLL, and multiple clock domains including global and regional clock structures for flexible clock distribution and dynamic clock control.
• Memory Subsystem (sysMEM) — Support for single, dual and pseudo-dual port modes, memory cascading, FIFO modes, and RAM initialization/ROM operation as described in the platform documentation.
• DSP and I/O — Integrated sysDSP resources and programmable I/O cells (PIC) with input, output, and tri-state register blocks for interface flexibility.
• High-Speed Interfaces — Platform-level support for DDR memory through DDRPHY and SERDES/PCS blocks and multi-protocol PHY/PCS elements as described in the Avant overview.
• Configuration & Reliability — Device configuration options include JTAG and platform-level SEU handling provisions noted in the Avant documentation.
• Compliance — RoHS compliant.

Unique Advantages

• High logic and memory density: 637,000 logic elements and approximately 4.24 Mbits of embedded RAM provide substantial on-chip resources for complex logic, buffering, and local storage needs.
• Large I/O count: 502 I/Os enable integration of wide external buses and multiple peripheral interfaces without resorting to external multiplexing.
• Platform-level feature set: The Avant platform provides PFU/slice architecture, rich clocking (PLL, on-chip oscillator, global/regional clocks), sysDSP and sysMEM capabilities to implement varied datapaths and memory configurations.
• Compact surface-mount package: 841-FCCSP (15×13) package supports high-density PCB layouts while maintaining a high pin count.
• Commercial temperature and RoHS compliance: Specified for 0 °C to 85 °C operation and RoHS compliant for standard commercial deployments.
