M68LC302CAF16VCT

The M68LC302CAF16VCT from NXP Semiconductors is an integrated multiprotocol microprocessor based on a static M68000 core running at 166 MHz. Designed for embedded and industrial applications, it combines a single 8/16-bit M68000 core with on-chip communications, DMA, timers and memory interfaces to simplify system design.

With a 3.3 V I/O domain, industrial temperature qualification and a compact 100-LQFP (14×14) surface-mount package, this part targets compact, low-power and height-restricted embedded solutions that require integrated serial protocols and real-time control.

Key Features

• Core – Static M68000 core providing a single 8/16-bit processing engine operating at 166 MHz for deterministic embedded control.
• 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 for flexible memory architectures.
• Communications & Co-Processing – Integrated communications subsystem (CP) with a RISC CPM and two full-duplex Serial Communication Controllers (SCCs) supporting HDLC/SDLC, UART and BISYNC modes for multiprotocol connectivity.
• DMA & Interrupts – Independent DMA channels and an interrupt controller with multiple modes for efficient data movement and prioritized real-time interrupt handling.
• Timers & Watchdog – Three timers including a watchdog timer and a periodic interrupt timer (PIT) to support robust timing, watchdog supervision and periodic task scheduling.
• Clocking & PLL – On-chip clock generator and PLL allowing operation with 32 kHz or 4 MHz crystals for flexible clock sources and low-power timing options.
• System Control & Low Power – System status/control logic with low-power standby modes and wake-up sources; freeze control for debugging in supported packages.
• Package & Environmental – 100-LQFP (14×14) surface-mount package, industrial qualification with operating temperature range −40 °C to 85 °C, and RoHS compliant.
• Voltage & I/O – 3.3 V IO domain suitable for common embedded system logic levels.
• Additional Interfaces – Includes General Control Interface (GCI) and multiple programmable chip-select lines with wait-state generator logic for flexible peripheral interfacing.

Typical Applications

• Industrial Control – Real-time control and supervisory tasks where industrial temperature range and integrated DMA/timers simplify system design.
• Communications Equipment – Multiprotocol serial interfaces and CPM-based co-processing for protocol handling and data link management.
• Compact Embedded Systems – Low-profile 100-LQFP packaging and low-power modes make it suitable for height-restricted and portable embedded devices.
• Legacy M68000-based Designs – Drop-in support for M68000 family systems that need integrated memory interfaces and peripheral control.

Unique Advantages

• Highly integrated solution: Combines CPU, communications co-processor, DMA, timers and on-chip RAM to reduce BOM and board area.
• Multiprotocol communications: Two SCCs plus a CPM provide built-in support for HDLC/SDLC, UART and BISYNC for diverse serial requirements.
• Flexible memory interfacing: Glueless interfaces to EPROM, SRAM, Flash and EEPROM plus DRAM refresh support simplify external memory integration.
• Deterministic real-time control: Hardware DMA, prioritized interrupts and multiple timers (including watchdog and PIT) enable reliable real-time operation.
• Compact industrial package: 100-LQFP (14×14) surface-mount package with −40 °C to 85 °C qualification supports compact, rugged designs.
• Power and clock flexibility: On-chip clock generator and PLL with low-power modes support efficient power management and multiple crystal options.
