MC68LC302AF16CT

The MC68LC302AF16CT is a low-cost integrated multiprotocol microprocessor from NXP Semiconductors based on a static M68000 core. It operates at 16 MHz with a single 8/16-bit core and is designed for embedded systems that require on-chip peripheral integration, compact packaging, and low-power operation.

Well suited to multiprotocol communications and portable/space-constrained designs, the MC68LC302 family delivers integrated DMA, interrupt control, timers and on-chip dual-port RAM to simplify system design and reduce board-level BOM.

Key Features

• Core & System  Static M68000 core supporting 8- or 16-bit operation with a system bus designed for embedded multiprotocol processing.
• Clock & Performance  16 MHz operating speed with an on-chip clock generator and on-chip PLL that supports operation with 32 kHz or 4 MHz crystals.
• Memory & DMA  On-chip 1152-byte dual-port RAM and independent DMA (IDMA) controller for efficient data movement and inter-module communication.
• Timers & Watchdog  Three timers including a watchdog timer and a periodic interrupt timer (PIT) for real-time control and system reliability.
• Interfaces & Communications  Integrated peripheral controllers including programmable I/O (PIO), communications RISC controller (CP/CPM), and additional interfaces such as GCI.
• Bus & Boot Flexibility  Glueless interface to EPROM, SRAM, Flash EPROM and EEPROM; supports boot in 8-bit mode with runtime switch to 16-bit mode and four programmable chip-select lines with wait-state logic.
• Power Management  New low-power (standby) modes with wake-up options and freeze control for debugging (feature details vary by package).
• Package & Temperature  Surface-mount 100-LQFP package (14 × 14 mm) with an operating temperature range of 0 °C to 70 °C and 5 V I/O signaling.
• Compliance  RoHS compliant.

Typical Applications

• Portable Communications Modules  Integrated DMA, timers and communications controllers make the device suitable for portable multiprotocol communications equipment where low power and compact size matter.
• Height‑Restricted Modules (e.g., PCMCIA)  Low-profile 100-LQFP package is targeted to space- and height-constrained form factors.
• Embedded Control and I/O Management  On-chip PIO, timers and DMA enable control tasks, peripheral management and deterministic event handling in embedded designs.
• Legacy 68000‑Family Designs  Static M68000 core supports migration or maintenance of systems based on the 68000 family with integrated modern system features.

Unique Advantages

• Highly integrated solution: Combines a static M68000 core with IDMA, interrupt controller, PIO and on-chip dual-port RAM to reduce external components and simplify board design.
• Compact, low-profile package: The 100-LQFP (14 × 14 mm) package reduces board space and enables use in height-restricted applications.
• Flexible clocking and boot options: On-chip PLL supporting 32 kHz or 4 MHz crystals plus 8-bit boot with switch to 16-bit runtime operation for flexible system start-up.
• Built-in reliability features: Watchdog timer, periodic interrupt timer and low-power standby modes support robust embedded operation and power management.
• Glueless memory interfaces: Direct interfacing to EPROM, SRAM, Flash EPROM and EEPROM simplifies memory integration and reduces design complexity.
