LC4032V-25TN48C: High-Speed 3.3V CPLD by Lattice Semiconductor | 32 Macrocells, 2.5ns Delay
The LC4032V-25TN48C from Lattice Semiconductor Corporation represents the pinnacle of high-performance Complex Programmable Logic Devices (CPLDs). Designed for engineers demanding both speed and flexibility, this 3.3V-operated CPLD delivers an exceptional 2.5ns maximum propagation delay, making it ideal for time-critical applications like real-time industrial controls and high-bandwidth data interfaces. With 32 macrocells organized into 2 logic blocks, the device offers remarkable logic density in a compact 48-TQFP package (7x7mm). Its in-system programmability (ISP) feature allows for field upgrades without physical removal from PCBs, significantly reducing development cycles and enabling agile hardware iterations.
At the heart of the LC4032V-25TN48C lies its advanced architecture featuring 32 fully configurable I/O pins that support versatile voltage level translation. The device operates reliably across industrial temperature ranges (0 C to 90 C junction temperature) with a tight 3.0V to 3.6V internal supply range, ensuring stable performance in electrically noisy environments. Each of the 32 macrocells can independently implement combinatorial or registered logic functions, while the global routing pool provides low-skew signal distribution. The surface-mount TQFP package enables high-density PCB layouts, with the 0.5mm pin pitch facilitating automated assembly processes for cost-effective manufacturing.
Key technical differentiators include the device's ultra-fast pin-to-pin delays (2.5ns typical) and clock frequencies exceeding 300MHz, enabling its use in high-speed state machines and bus interface applications. The CPLD incorporates advanced power management features, including programmable slew rate control and individual output enable per macrocell, reducing overall system power consumption. Security features include 128-bit AES programming encryption and read-back protection, critical for IP-sensitive designs. Lattice's proven ispLEVER design tools provide comprehensive support for Verilog and VHDL development flows, with seamless integration into popular third-party EDA environments.
The LC4032V-25TN48C excels in diverse applications including: Industrial Automation (PLC I/O expansion, motor control timing), Communications Infrastructure (protocol bridging, packet processing), Consumer Electronics (display interface logic, touchscreen controllers), and Automotive Systems (sensor conditioning, lighting control). Its combination of deterministic timing, instant-on operation, and radiation tolerance makes it particularly suitable for mission-critical systems where FPGA alternatives may introduce boot-time latency or configuration volatility.
Engineers will appreciate the device's deterministic timing characteristics, which eliminate the configuration uncertainties of FPGA solutions. The non-volatile configuration memory ensures instant operation upon power-up, while the single-chip solution reduces board space requirements compared to discrete logic alternatives. Lattice provides comprehensive technical documentation including detailed IBIS models for signal integrity analysis and industry-standard JEDEC files for programming equipment compatibility. For volume production, the LC4032V-25TN48C is available in tape-and-reel packaging compatible with high-speed pick-and-place assembly lines, supported by Lattice's global distribution network guaranteeing supply chain reliability.
