Low Cost, Low Power SPI4.2 Cores Bolstered With Enhanced Buffer Management Features
HILLSBORO, OR - NOVEMBER 19, 2008 - Lattice Semiconductor (NASDAQ: LSCC) today announced that its industry-leading LatticeSCM™ FPGA family-based SPI4.2 MACO™ (“Masked Array for Cost Optimization”) cores have been enhanced by adding sophisticated link layer buffer management options. Compared to competitive FPGAs, the LatticeSCM FPGA family has offered the industry’s most feature-rich SPI4.2-based cores and bridge reference designs at the lowest cost, power and printed circuit board footprint. These new features enhance this solution portfolio by allowing designers the option to use a parameterizable buffer manager for applications needing per-channel bandwidth management.
“We continue to enhance our SPI4.2 solution portfolio by integrating sophisticated system-level features, while maintaining the low cost and power targets that have made Lattice a leading SPI4.2 programmable gasket solution provider,” said Shakeel Peera, Director of Strategic Marketing for SRAM FPGAs. “Designers working on 10G Carrier Ethernet and Packet over SONET platforms will find these features useful as they architect systems designed around determinism and Service Level Agreement (SLA) guarantees.”
The LatticeSCM FPGA platform provides designers with multiple hardened SPI4.2 cores using Lattice’s exclusive MACO structured ASIC technology. MACO technology delivers pre-engineered, standard-compliant IP functions, developed by Lattice, that shorten end-system time to market and dramatically lower device cost, power and PCB footprint targets. These new features provide designers with a programmable buffer manager capable of:
- Up to 16 separate physical FIFOs per TX/RX direction
- Packet over-flow and error drop
- Both store & forward as well as cut-through operation
- Parameterizable buffer depth and thresholds
- Dynamic channel provisioning
- Programmable sequencer-based scheduler
