ISPLSI 2032E-110LT48

Complex Programmable Logic Devices Overview

The ispLSI 2032E-110LT48 is a high-density, in-system programmable complex programmable logic device (CPLD) manufactured by Lattice Semiconductor. It features 1000 PLD gates organized into eight Generic Logic Blocks (GLBs), providing 32 universal I/O pins and two dedicated inputs. The device utilizes E2CMOS technology with non-volatile EEPROM storage, allowing for over 10,000 erase/reprogram cycles. Designed for commercial operation between 0°C and +70°C, it operates on a 5V core voltage. The -110 speed grade supports a maximum operating frequency of 110 MHz with a typical propagation delay of 10 ns. It includes three dedicated clock input pins and supports mixed-voltage I/O (3.3V or 5V) via the VCCIO supply.

Complex Programmable Logic Devices Feature Summary

• Contains 1000 PLD gates, 32 macrocells, and 8 GLBs with a Global Routing Pool for complete interconnectivity.
• Supports In-System Programming (ISP) via IEEE 1149.1 JTAG interface using ispJTAG technology.
• Features user-selectable 3.3V or 5V I/O levels in the 48-pin package, enabling mixed-voltage system compatibility.
• Includes programmable output slew rate control and open-drain output options to minimize switching noise.

Complex Programmable Logic Devices Applications

• Glue logic replacement in digital circuits.
• Address decoding and bus bridging applications.
• State machine implementation and counter designs.
• Prototyping of complex logic functions prior to ASIC fabrication.

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific ordering suffix LT48 corresponds to the 48-pin TQFP package variant. Ensure that design specifications align with the commercial temperature range (0°C to +70°C) and 5V logic core requirements defined in the datasheet.

Complex Programmable Logic Devices Selection Notes

Select this model when a 110 MHz performance level is sufficient for the target application. The 48-pin TQFP package is required for mixed-voltage I/O support; other packages may not offer this feature. Consider the -225 speed grade if higher frequencies up to 225 MHz are needed, as recommended for new designs by the manufacturer.

Complex Programmable Logic Devices Part Context

This component belongs to the ispLSI 2000E family, which offers enhanced manufacturing yields and reprogrammability compared to earlier generations. It is functionally and JEDEC upward compatible with the ispLSI 2032 devices. The manufacturer recommends the ispLSI 2032E-225 series for new designs due to superior performance characteristics.

Complex Programmable Logic Devices Replacement Considerations

The ispLSI 2032E-225LT48 is a faster alternative within the same family offering 225 MHz performance. For legacy replacements, the ispLSI 2032A series provides form and function compatibility with identical packaging but different timing specifications.
