MC68LC302AF16VCT

The MC68LC302AF16VCT is an integrated multiprotocol microprocessor from NXP Semiconductors based on a static M68000 core. It provides a single 8/16-bit M68000-family core running at 16 MHz with on-chip communications and system peripherals targeted at embedded applications.

Designed for compact, low-power embedded systems, the device combines processor, DMA, timers, on-chip dual-port RAM and communications controllers in a 100‑LQFP (14×14 mm) surface-mount package, delivering a space-efficient building block for multiprotocol and portable designs.

Key Features

• Core  Static M68000 core supporting 8- or 16-bit system operation at 16 MHz, providing compatibility with M68000-family system designs.
• Memory  On-chip 1152‑byte dual-port RAM and support for DRAM controllers; programmable address mapping for on-chip RAM and IMP registers.
• Interfaces & Communications  Integrated communications processing resources including a RISC CPM co-processor and two full‑duplex serial communications controllers (SCCs) supporting HDLC/SDLC, UART and BISYNC modes as described in the product family documentation.
• DMA and Bus  Independent DMA (IDMA) controller and a general-purpose DMA channel for efficient data movement; four programmable chip-select lines with wait-state generator for glueless interfacing to EPROM, SRAM, Flash and EEPROM.
• Timers & Watchdog  Three on-chip timers including a watchdog timer and a periodic interrupt timer (PIT) for system timing and reliability functions.
• System Control & I/O  Interrupt controller with selectable modes, parallel I/O ports (some with interrupt capability), system status/control logic and options for low-power standby modes and hardware watchdog control.
• Clocking & Boot  On-chip clock generator and PLL supporting operation with 32 kHz or 4 MHz crystals; supports boot in 8-bit mode with the ability to switch to 16-bit operation.
• Electrical & Packaging  3.3 V I/O voltage, surface-mount 100‑LQFP (14×14 mm) package, and an operating temperature range of 0 °C to 70 °C.

Typical Applications

• Embedded Multiprotocol Communications  Integrated SCCs and CPM support HDLC/SDLC, UART and BISYNC modes for communications modules and protocol gateways.
• Portable/Low‑Power Devices  Low-power standby modes, on-chip clocking and a low-profile 100‑LQFP package make the device suitable for height-restricted and battery‑sensitive designs.
• Compact System Controllers  On-chip DMA, timers, PIO and dual‑port RAM enable compact controller designs for embedded appliances and subsystems.
• Memory‑Mapped Embedded Designs  Glueless interface to EPROM, SRAM, Flash and EEPROM plus programmable chip-selects simplify external memory integration and boot configurations.

Unique Advantages

• Highly integrated solution: Combines a static M68000 core, DMA, dual‑port RAM and communications controllers on-chip to reduce BOM and board complexity.
• Space-efficient package: 100‑LQFP (14×14 mm) surface-mount package reduces PCB area and supports height-restricted applications.
• Flexible bus operation: Supports 8‑bit boot and run‑time switch to 16‑bit operation for compatibility with a range of memory and system configurations.
• Rich timing and reliability features: Includes three timers, a watchdog timer and a periodic interrupt timer to support robust system supervision and scheduling.
• On-chip clocking and PLL: Built‑in clock generator and PLL support crystal options for simplified clock design and stable system timing.
• Glueless external memory interface: Programmable chip-selects and wait-state logic allow direct connection to common nonvolatile and volatile memories without complex bus glue logic.
