MC68LC302CPU16CT

The MC68LC302CPU16CT is a low-cost integrated multiprotocol microprocessor from NXP Semiconductors, based on a static M68000 core running at 16 MHz. It combines a single 8/16-bit M68000-family CPU core with on-chip system peripherals and communication controllers to address embedded and industrial applications.

Designed for compact, low-power systems, the device integrates DMA, interrupt control, timers, dual-port RAM and serial communication controllers, making it suited for portable, height-restricted and industrial embedded designs that require on-chip integration and predictable operating parameters.

Key Features

• Core and Architecture  Static M68000 core supporting 8- or 16-bit operation with a 16 MHz clock speed for deterministic embedded processing.
• Integrated Communications  Includes a communications processor (RISC CPM) and two full-duplex serial communications controllers (SCCs) for multiprotocol serial interfaces.
• DMA and Interrupts  On-chip independent DMA (IDMA) channels and an interrupt controller with selectable modes to manage peripheral data flow and event handling.
• On-Chip Memory  1152 bytes of dual-port RAM and system bus support to simplify shared data access between CPU and peripherals.
• Timers and Watchdog  Three timers including a watchdog and a periodic interrupt timer (PIT) for real-time scheduling and system supervision.
• System Integration  On-chip clock generator and PLL, programmable chip-select lines with wait-state logic, and glueless interface capability to EPROM, SRAM, Flash and EEPROM for straightforward system integration.
• Boot and Mode Flexibility  Support for booting in 8-bit mode with capability to switch to 16-bit operation at runtime.
• Package and Mounting  Low-profile 100-LQFP (14×14 mm) surface-mount package suitable for height-restricted board designs.
• Operating Conditions  Industrial-grade qualification with an operating temperature range of −40 °C to 85 °C and 5 V I/O voltage.
• RoHS Compliance  Component is RoHS compliant for regulated manufacturing environments.

Typical Applications

• Portable and Height-Restricted Modules  Low-profile 100-LQFP package and on-chip integration make the device suitable for PCMCIA-style and other compact modules where board space and height are constrained.
• Multiprotocol Communications Equipment  On-chip RISC communications processor and SCCs enable implementation of serial protocols and data link functions in embedded modems, terminals and gateways.
• Industrial Embedded Control  Integrated timers, watchdog and DMA support reliable control functions and real-time task handling in industrial automation and control systems.
• Low-Power Portable Devices  Designed with low-power modes and an on-chip clock/PLL, the device targets battery-aware portable applications requiring reduced external component count.

Unique Advantages

• Highly integrated multiprotocol processing  Combines an M68000 core, RISC communications processor and serial controllers to reduce external IC count and simplify board design.
• Built-in DMA and dual-port RAM  Independent DMA channels and 1152 bytes of dual-port RAM enable efficient data movement between peripherals and CPU with minimal CPU overhead.
• Flexible system interfacing  Programmable chip-selects, glueless memory interfacing and on-chip clocking reduce the need for external glue logic and simplify memory subsystem design.
• Real-time supervision  Multiple timers including a watchdog and PIT provide deterministic timing and fault recovery for embedded control tasks.
• Compact, industrial-ready package  100-LQFP surface-mount package and −40 °C to 85 °C operating range support industrial boards and constrained mechanical designs.
• Regulatory-friendly  RoHS compliance supports environmental and manufacturing requirements.
