ISPLSI-2032VL-110LB49

Overview

The ISPLSI-2032VL-110LB49 is a 3.3V In-System Programmable High Density SuperFAST PLD from Lattice Semiconductor. It features 1000 PLD gates, 32 I/O pins with two dedicated inputs, and 32 registers. The device utilizes High Speed Global Interconnect and Wide Input Gating for fast counters and state machines. It operates at a maximum frequency of 300 MHz with a propagation delay of 3.0 ns. The architecture interfaces with standard 5V TTL devices while maintaining 100% functional and pinout compatibility with the ispLSI 2032V series.

Feature Summary

• SuperFAST Architecture: 1000 PLD gates, 32 I/Os, 32 registers, and high-speed global interconnect.
• High Performance: fmax = 300 MHz, tpd = 3.0 ns using E2CMOS technology.
• In-System Programmability: Supports reprogramming via Boundary Scan Test Access Port (TAP).
• Compatibility: 100% JEDEC and pinout compatible with ispLSI 2032V devices.

Applications

• Address decoding logic
• Fast counters and state machines
• Random logic implementation
• Wired-OR or bus arbitration logic

Procurement Notes

Verify the specific suffix 'VL' against official Lattice documentation to confirm voltage and speed grade distinctions compared to the standard 'VE' variant. Ensure the LB49 package code corresponds to the required 49-pin BGA footprint. Confirm RoHS compliance status if lead-free packaging is mandatory for the assembly process.

Selection Notes

Select this component when 3.3V operation is required alongside 5V TTL interface compatibility. The 300 MHz speed grade suits high-frequency digital control applications. Verify that the design fits within the 1000 gate limit and utilizes the 32 available macrocells effectively for the target logic complexity.

Part Context

This part belongs to the ispLSI 2000VE/VL family of Electrically Erasable PLDs. It serves as a drop-in replacement for the older ispLSI 2032V in terms of functionality and pinout, offering improved performance and lower voltage operation capabilities while retaining non-volatile configuration storage.

Replacement Considerations

The datasheet confirms 100% functional and pinout compatibility with the ispLSI 2032V device. Designers migrating from the 2032V can utilize this part without schematic changes, provided the power supply voltage is adjusted to 3.3V.
