M68LC302CAF20VCT

The M68LC302CAF20VCT is an integrated multiprotocol microprocessor based on a static M68000 core, optimized for embedded and industrial applications. It combines a single 8/16-bit M68000 core running at 20 MHz with on-chip system peripherals to deliver a compact, low-power processing node for communication and control tasks.

This device targets embedded systems that require on-chip DMA, timers, serial communications and flexible memory interfacing while operating across an industrial temperature range. Key value comes from its high integration, low-profile 100-LQFP (14×14) package and on-chip clocking and power features that reduce external component count.

Key Features

• Core  Static M68000 core supporting 8- or 16-bit M68000 family systems; single-core architecture optimized for embedded control.
• Performance & Power  20 MHz operating speed with new low-power (standby) modes and freeze control for debugging to support power-sensitive applications.
• Memory  On-chip 1152-byte dual-port RAM and programmable address mapping; DRAM refresh controller and glueless interface to EPROM, SRAM, Flash EPROM and EEPROM.
• DMA & Interrupts  Independent Direct Memory Access (IDMA) controller, general-purpose DMA channel and an interrupt controller with two modes of operation for deterministic data movement and event handling.
• Communications Processor (CP)  Integrated RISC main controller and two full-duplex Serial Communications Controllers (SCCs) supporting HDLC/SDLC, UART, BISYNC, transparent modes and autobaud for multiprotocol serial links.
• Timers & Watchdog  Three timers including a watchdog timer and a new periodic interrupt timer (PIT) to support time-critical and safety-related functions.
• System & I/O  Parallel I/O ports (some with interrupt capability), four programmable chip-select lines with wait-state logic, and on-chip clock generator with PLL enabling operation with 32 kHz or 4 MHz crystals.
• Package & Environment  100-LQFP (14×14) low-profile surface-mount package; industrial qualification and specified operating temperature range of −40 °C to 85 °C. I/O voltage: 3.3 V.

Typical Applications

• Legacy MC68302-based designs  Drop-in upgrade or replacement in systems that require M68302 family compatibility but with updated static 68000 core and low-profile packaging.
• Industrial communications controllers  Multiprotocol serial interfaces and on-chip DMA make the device suitable for protocol conversion, remote I/O and fieldbus interface modules.
• Portable and low-power embedded equipment  Low-power modes, PLL clock options and compact 100-LQFP package support height-restricted and battery-sensitive products.
• Embedded control and monitoring  Integrated timers, watchdog and interrupt-capable I/O are suited to real-time control, process monitoring and subsystem controllers in industrial systems.

Unique Advantages

• Highly integrated multiprotocol processor: Combines M68000 core, RISC CP and two SCCs to handle diverse serial protocols without large external controller arrays.
• Reduced board space: Low-profile 100-LQFP (14×14) package and on-chip peripherals lower PCB area and component count for compact designs.
• Flexible memory interfacing: Glueless connections to EPROM, SRAM, Flash EPROM and EEPROM plus programmable chip-selects simplify memory subsystem design.
• Robust timing and reliability features: On-chip watchdog, PIT and multiple timers provide deterministic timing and supervisory functions for industrial systems.
• On-chip clocking and PLL: Built-in clock generator and PLL operation with 32 kHz or 4 MHz crystals reduce the need for external clock components.
• Industrial temperature rating: Specified for −40 °C to 85 °C operation to meet common industrial environmental requirements.
