KMC68LC302AF20CT

The KMC68LC302AF20CT is an integrated multiprotocol microprocessor from NXP Semiconductors featuring a static M68000 core and a 20 MHz operating speed. Designed for embedded communications and control applications, it combines a 8/16-bit system bus architecture with on-chip controllers and peripherals to simplify system design and reduce board-level integration.

This device targets compact, low-power embedded systems that require multiprotocol serial communications, flexible memory interfacing and integrated timing and DMA resources, while offering RoHS compliance and surface-mount packaging for modern manufacturing.

Key Features

• Core and Architecture Static M68000 core supporting 8- or 16-bit system operation with a 20 MHz clock speed, providing compatibility with M68000-family designs.
• Integrated Communications and Co-Processing Includes an on-chip communications processor (RISC CPM) and serial communications controllers supporting common protocols and serial modes for embedded communications tasks.
• Memory and DMA On-chip 1152-byte dual-port RAM and independent DMA controller(s) enable efficient data movement and shared-memory communication between subsystems.
• Timers and System Control Three timers including a watchdog timer and a periodic interrupt timer (PIT) provide robust timekeeping and fail-safe monitoring; system control features include low-power standby modes and clock/PLL options.
• Flexible Bus and Boot Options Glueless interface to EPROM, SRAM, Flash EPROM and EEPROM, four programmable chip-select lines with wait-state generation and programmable address mapping support a range of memory configurations and boot strategies including 8-bit boot and 16-bit runtime.
• Package and Environmental 100-LQFP (14 × 14 mm) surface-mount package optimized for space-constrained designs; operating temperature range 0 °C to 70 °C and RoHS-compliant.
• Supply and I/O Standard 5 V I/O supply for compatibility with legacy embedded systems.

Typical Applications

• Embedded Communications Modules — Implement protocol handling and serial data processing using the on-chip communications processor and serial controllers for gateways and protocol converters.
• Portable and Low-Power Devices — Low-power modes and on-chip clock/PLL support make the device suitable for battery-powered or space-constrained portable systems.
• Bootable Control Systems — Glueless interface to nonvolatile memory and programmable chip-selects enable compact EPROM/Flash-based control and boot configurations.
• Industrial and Consumer Embedded Control — Integrated timers, watchdog, DMA and PIO support typical control, monitoring and user-interface tasks in embedded products.

Unique Advantages

• Highly Integrated Multiprotocol Capability: Combines an M68000 core with a RISC communications processor and serial controllers to reduce external silicon and simplify board design.
• On-Chip Shared RAM: 1152-byte dual-port RAM enables efficient inter-module communication and low-latency data sharing without external memory for many control tasks.
• Flexible Memory Interfacing: Glueless connection to EPROM, SRAM, Flash and EEPROM plus programmable chip-selects reduce BOM and speed time-to-market for memory-mapped designs.
• Robust Timing and Reliability: Multiple timers including watchdog and PIT provide reliable supervision and deterministic interrupt timing for embedded control.
• Compact, Surface-Mount Package: 100-LQFP (14 × 14 mm) package keeps board area minimal while supporting standard SMT assembly processes.
• Standards-Compatible I/O and Power: 5 V I/O and defined operating range (0 °C to 70 °C) align with common embedded system requirements and manufacturing practices.
