MC68LC302PU20VCT

The MC68LC302PU20VCT is an integrated multiprotocol microprocessor from NXP Semiconductors, based on a static M68000 core. This surface-mount device operates at 20 MHz with a 3.3 V I/O supply and supports 8- or 16-bit system bus widths, delivering an integrated solution for embedded communications and control applications.

Designed for compact and height-restricted designs, the MC68LC302 combines on-chip processing, communications controllers, timers and dual-port RAM to simplify board-level design while supporting common serial protocols and system peripherals.

Key Features

• Core Static M68000 core supporting 8‑ or 16‑bit M68000 family systems; single-core operation at 20 MHz.
• Memory On-chip 1,152‑byte dual‑port RAM with programmable address mapping and system RAM/ROM support; DRAM controller and refresh support.
• DMA and System Bus Independent direct memory access (IDMA) controller and DMA channels for offloading data movement from the CPU.
• Communications Processor (CP) Integrated RISC-based main controller and two independent full‑duplex serial communications controllers (SCCs) supporting HDLC/SDLC, UART and BISYNC style protocols.
• Timers and Watchdog Multiple on‑chip timers including a watchdog timer and a periodic interrupt timer (PIT) for real‑time control and system supervision.
• Clock and PLL On‑chip clock generator with output and on‑chip PLL supporting operation with 32 kHz or 4 MHz crystals for flexible clocking options.
• System Interfaces Parallel I/O ports (some with interrupt capability), four programmable chip‑select lines with wait‑state generator logic, and glueless interfaces to EPROM, SRAM, Flash and EEPROM for straightforward memory integration.
• Package and Mounting Low‑profile 100‑LQFP (14 × 14 mm) surface‑mount package suited to height‑restricted designs.
• Operating Range Specified operating temperature range of 0 °C to 70 °C and 3.3 V I/O voltage.

Typical Applications

• Portable and Height‑Restricted Modules Suitable for compact designs where low profile packaging and integrated peripherals reduce board area and height, including PCMCIA‑style modules.
• Multiprotocol Communications Equipment On‑chip SCCs and CP support standard serial protocols (HDLC/SDLC, UART, BISYNC) for embedded communications controllers and protocol converters.
• Embedded Control and Supervision Integrated timers, watchdog and DMA make the device appropriate for embedded controllers requiring deterministic timing and reduced external logic.
• Memory‑Mapped Embedded Systems Glueless interfaces to EPROM/SRAM/Flash and programmable chip‑selects simplify designs that require direct memory expansion or boot from external nonvolatile storage.

Unique Advantages

• Highly integrated multiprotocol processor: Combines M68000 core, communications controllers, DMA, timers and dual‑port RAM to reduce BOM and simplify board design.
• Static M68000 core: Static core operation with 8/16‑bit bus support enables flexible system data width and simpler timing control.
• Compact, low‑profile package: 100‑LQFP (14×14 mm) surface‑mount package reduces board area and is suitable for height‑restricted assemblies.
• Flexible clocking and boot options: On‑chip clock generator and PLL supporting 32 kHz or 4 MHz crystals, plus boot in 8‑bit mode with runtime switch to 16‑bit mode.
• Built‑in system peripherals: On‑chip timers, watchdog, programmable chip‑selects and glueless memory interfaces lower external component count and integration effort.
• Designed for embedded communications: Two SCCs with support for common serial protocols provide ready‑made interfaces for data link and asynchronous communications tasks.

Why Choose MC68LC302PU20VCT?

The MC68LC302PU20VCT positions itself as an integrated solution for embedded applications that require a classic M68000 architecture with built‑in communications and system peripherals. With its static 68000 core, on‑chip dual‑port RAM, DMA support, dedicated communications controllers and flexible clocking, it streamlines designs where board space, integrated peripherals and predictable timing are priorities.

This device is well suited to engineers building compact communications modules, embedded controllers and memory‑mapped systems that benefit from a single‑chip multiprotocol processor in a low‑profile surface‑mount package. Its integration reduces external components and design complexity while providing clear, verifiable hardware features for long‑term embedded designs.
