Lattice LCMXO1200C-5MN132C: A Comprehensive Technical Overview of the Low-Cost, Low-Power CPLD

The Lattice LCMXO1200C-5MN132C represents a key component within Lattice Semiconductor's renowned low-power, low-cost FPGA/CPLD portfolio. As a member of the MachXO™ family, this device is engineered to bridge the gap between traditional complex FPGAs and simple PLDs, offering a unique blend of programmability, efficiency, and economy. It is specifically designed for a vast array of general-purpose logic integration applications, including system management, bus bridging, power-up control, and I/O expansion.

Fabricated on a advanced, low-power process technology, the LCMXO1200C is architected for exceptional power efficiency. It features a non-volatile, flash-based configuration memory, which is a cornerstone of its design. This technology eliminates the need for an external boot PROM, simplifying board design and reducing both component count and total system cost. The device instantly becomes operational upon power-up, enabling immediate system functionality—a critical feature for control and management applications.

At the heart of this CPLD lies a flexible logic structure. The -1200C designation signifies it contains approximately 1200 Look-Up Tables (LUTs), which serve as the fundamental building blocks for implementing custom digital logic. This logic capacity is sufficient for integrating dozens of discrete ICs into a single, reconfigurable chip. The device is packaged in a compact 5mm x 5mm, 132-ball caBGA (MN132C) package. This tiny form factor is essential for modern, space-constrained electronic designs, from consumer gadgets to compact industrial controllers.

The device's I/O capabilities are highly versatile. It supports a wide range of single-ended I/O standards (LVCMOS, LVTTL) and can interface with multiple voltage levels (1.2V, 1.5V, 1.8V, 2.5V, 3.3V), making it ideal for level translation and bridging between processors and peripherals operating at different voltages. Furthermore, it incorporates robust features like on-chip user flash memory (UFM). This embedded non-volatile storage is perfect for storing device serial numbers, system calibration data, or small boot code, adding another layer of integration.

Design and development for the LCMXO1200C are supported by Lattice's powerful and user-friendly Lattice Diamond® and Lattice Radiant® design software suites. These environments provide a complete flow for design entry, synthesis, place-and-route, and verification, significantly accelerating time-to-market for projects utilizing this CPLD.

ICGOOODFIND: The Lattice LCMXO1200C-5MN132C stands out as an exceptionally efficient and cost-optimized solution for logic consolidation. Its combination of instant-on operation, ultra-low power consumption, and high integration in a miniature package makes it a superior choice over discrete logic and ASSPs for a multitude of control-oriented applications in consumer, communications, computing, and industrial markets.
