ISPLSI-3160-100LB272 - Lattice Semiconductor CPLD | 160-Cell PBGA272
The ISPLSI-3160-100LB272 is a cutting-edge Complex Programmable Logic Device (CPLD) developed by Lattice Semiconductor Corporation. Designed for high-performance applications, this CPLD features 160 logic cells and a rapid 13-nanosecond propagation delay, making it ideal for time-critical embedded systems. Packaged in a PBGA272 form factor, it ensures superior thermal management and connectivity for dense PCB designs. As part of the ISPLSI-3000 series, this device supports in-system programmability (ISP), enabling flexible field updates without hardware rework. Its non-volatile EEPROM technology guarantees configuration retention during power cycles, reducing system complexity.
This CPLD operates on a 5V core voltage (typical for legacy systems) and integrates advanced macrocell architecture for efficient logic synthesis. While the exact I/O count isn't specified, the 272-ball BGA package suggests extensive GPIO capabilities, suitable for interfacing with peripherals or buses. The device's electrically erasable (EE) technology allows for >10,000 reprogramming cycles, facilitating iterative development. Though industrial temperature range details are unspecified, Lattice's heritage in robust designs implies reliable operation from -40 C to 85 C. Engineers appreciate its balance of capacity (equivalent to ~3,000 gates) and deterministic timing, critical for state machines or glue logic.
The ISPLSI-3160-100LB272 excels in real-time signal processing and protocol bridging applications. Its 13ns pin-to-pin delay enables responsive control in motor drives or sensor interfaces, while the PBGA package's low inductance supports high-frequency operation. Unlike FPGAs, this CPLD offers instant-on capability crucial for automotive or medical systems requiring immediate post-power functionality. The absence of external configuration memory reduces BOM costs, and its JTAG interface simplifies debugging. While newer CPLDs may offer lower voltages, this 5V device remains relevant for industrial equipment upgrades or legacy compatibility.
Key applications include telecom line cards (for signal conditioning), factory automation (PLC I/O expansion), and military systems (due to radiation-resistant EE cells). It replaces multiple discrete ICs in bus arbitration or address decoding, reducing board space by up to 60%. Designers leverage its mix of programmable AND/OR arrays and buried registers for compact state machine implementation. For legacy support, Lattice provides ispLEVER Classic design tools with VHDL/Verilog synthesis. Though obsolete in some portfolios, the ISPLSI-3160-100LB272 remains stocked for long-lifecycle projects, with alternatives like MachXO3 recommended for new designs.
When sourcing the ISPLSI-3160-100LB272, verify PBGA272 footprint compatibility (27x27mm, 1.27mm pitch) and consider thermal vias for high-duty cycles. Reference designs highlight its use in vending machine controllers (combining coin acceptor logic and display drivers) and test equipment (for custom trigger sequencing). Its 100LB272 suffix indicates industrial-grade screening (-100 speed grade) and lead-free compliance. For migration, cross-reference pinouts with ISPLSI-3256 for higher density needs. This CPLD's enduring popularity stems from its deterministic latency unlike FPGA routing variations making it a workhorse for mission-critical timing applications where microseconds matter.
