ISPLSI 2032A-110LT48

Complex Programmable Logic Devices Overview

The ispLSI 2032A-110LT48 is a high-density complex programmable logic device (CPLD) manufactured by Lattice Semiconductor. It features 1000 PLD gates, 32 universal I/O pins, two dedicated inputs, and three dedicated clock inputs. Built on advanced 0.35-micron E2CMOS technology, it supports in-system programming via a 5V core. The device operates at a maximum frequency of 111 MHz with a propagation delay of up to 10 ns. It contains eight Generic Logic Blocks (GLBs) with 32 registers and utilizes a Global Routing Pool for interconnectivity. The component is housed in a 48-pin Thin Quad Flat Package (TQFP).

Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix 'LT48' corresponds to the commercial grade 48-pin TQFP package. Confirm that the -110 speed grade meets the system timing requirements of 111 MHz fmax. Check current product status as some devices in this family have been discontinued; consult manufacturer notices for availability or recommended replacements like the ispLSI 2032E series.

Complex Programmable Logic Devices Selection Notes

Select this part when 1000 PLD gates and 32 I/Os are sufficient for the design. Ensure the design fits within the 32 macrocell limit. Verify that 5V I/O levels are compatible with the rest of the system, as the device is TTL compatible. Consider the -110 speed grade if 10 ns propagation delay is acceptable. For new designs, evaluate the ispLSI 2032E series as recommended by the manufacturer.

Complex Programmable Logic Devices Part Context

The ispLSI 2032A-110LT48 belongs to the ispLSI 2032/A family, which is form and function compatible with the original ispLSI 2032 but built on an advanced 0.35 micron process. This family offers non-volatile reprogrammability and in-system diagnostic capabilities. The 'A' variant provides enhanced performance and lower power consumption compared to earlier generations while maintaining pinout compatibility.

Complex Programmable Logic Devices Replacement Considerations

The datasheet recommends using the ispLSI 2032E series for new designs. The ispLSI 2032A is fully form and function compatible with the ispLSI 2032. Specific cross-references should be verified against the manufacturer's obsolescence notices.
