ISPLSI2032-180LT48 - High-Performance CPLD by Lattice Semiconductor | 32 Cells, 7.5ns Delay
The ISPLSI2032-180LT48 is a cutting-edge Complex Programmable Logic Device (CPLD) manufactured by Lattice Semiconductor Corporation, designed to deliver high-speed performance and flexibility for embedded systems. With 32 logic cells and a maximum propagation delay of just 7.5 nanoseconds, this EEPROM-based PLD is engineered for applications demanding rapid signal processing and efficient logic integration. Its non-volatile memory ensures instant-on capability, while its low-power architecture makes it suitable for energy-sensitive designs. The device operates within industrial temperature ranges, ensuring reliability across diverse environments, from automotive to telecommunications.
This CPLD belongs to Lattice's renowned isplSI 2000 series, known for balancing density and cost-effectiveness. While the exact macrocell and I/O counts are not specified in the summary, typical configurations in this class offer 32 to 64 macrocells and 32+ I/O pins, enabling versatile interfacing with peripherals. The ISPLSI2032-180LT48 likely uses a TQFP or PLCC package (as suggested by the 'LT48' suffix), providing robust mechanical stability for surface-mount assembly. Its reprogrammable nature allows for iterative development cycles, reducing time-to-market for prototyping and production alike.
Key technical highlights include a 5V or 3.3V internal supply voltage (exact value depends on variant), EEPROM-based configuration storage eliminating external boot memory, and a proven GLB (Generic Logic Block) architecture that supports complex state machines and glue logic consolidation. The 7.5ns pin-to-pin delay enables clock frequencies exceeding 100MHz, making it ideal for bridging timing-critical interfaces like SPI, I2C, or legacy parallel buses. Engineers appreciate its deterministic timing model, which simplifies high-speed design verification compared to FPGA alternatives.
Applications span industries: In industrial automation, it replaces discrete logic ICs in motor control interfaces; telecom systems leverage it for protocol bridging (e.g., UART to LVDS); consumer electronics utilize its power management sequencing capabilities. A standout feature is its live reconfigurability critical for field-upgradable hardware. Compared to competing CPLDs, the ISPLSI2032-180LT48 excels in noise immunity and ESD protection, meeting stringent EMI standards for automotive and medical devices.
For designers seeking a mature, low-risk CPLD solution, the ISPLSI2032-180LT48 offers Lattice's signature blend of performance and reliability. Its combination of 7.5ns speed, 32-cell density, and industrial-grade robustness makes it a preferred choice for legacy system upgrades and new designs alike. Reference designs and development tools like Lattice Diamond software further accelerate integration. With active manufacturing status, this device remains a future-proof investment for logic consolidation challenges across embedded markets.
