LC4032V-10TN48I CPLD - High-Performance Programmable Logic Device | Lattice Semiconductor
The LC4032V-10TN48I from Lattice Semiconductor is a cutting-edge Complex Programmable Logic Device (CPLD) engineered for high-speed, low-power embedded applications. With its 32 macrocells and 10ns propagation delay, this device delivers exceptional performance for logic-intensive designs. The 3.3V operation makes it compatible with modern low-voltage systems while maintaining robust noise immunity. Its 48-LQFP package (7x7mm) offers a compact footprint for space-constrained PCB layouts. The device supports in-system programming (ISP), enabling field updates without physical removal, a critical feature for iterative development and post-deployment upgrades.
Architecturally, the LC4032V-10TN48I features two programmable logic blocks with 32 macrocells total, providing flexible implementation of combinational and sequential logic. Each macrocell includes programmable AND/OR arrays and flip-flops with clock enable controls. The device offers 32 I/O pins with individual programmable slew rate control (3.3V LVCMOS/LVTTL compatible). Notably, it operates across an industrial temperature range (-40 C to +105 C junction temperature), making it suitable for harsh environments. The integrated ISP circuitry complies with IEEE 1532 standards for streamlined programming through JTAG interfaces.
Performance-wise, the LC4032V-10TN48I achieves 10ns pin-to-pin delays while consuming minimal standby current (typically 50 A). The advanced CMOS process technology enables high-speed operation up to 200MHz internal frequency. Security features include programmable security bit protection to prevent unauthorized access to configuration data. Power management capabilities include programmable power-down modes and hot-socketing protection (I/O tolerance to 3.6V during power-up). These characteristics make it particularly suitable for interface bridging, protocol conversion, and control plane applications where reliability and deterministic timing are paramount.
The LC4032V-10TN48I excels in diverse applications including industrial automation (PLC I/O expansion, motor control), automotive electronics (sensor interfacing, CAN/LIN bus management), and consumer devices (display controllers, peripheral management). Its combination of deterministic timing, reprogrammability, and small form factor makes it ideal for legacy system upgrades where full FPGA solutions would be over-engineered. The device is supported by Lattice's Diamond Programmer software and third-party synthesis tools, streamlining integration into existing design workflows. For high-volume applications, the LC4032V-10TN48I offers cost-effective programmable logic without sacrificing performance or reliability.
