MC68LC302PU16CT

The MC68LC302PU16CT is a low-cost integrated multiprotocol processor from NXP Semiconductors, featuring a static M68000 core operating at 16 MHz. Designed for embedded applications, it provides a compact, surface-mount 100-LQFP (14×14) package and on-chip subsystems that simplify board design for communications and portable systems.

With integrated DMA, timers, dual-port RAM and serial controllers, the MC68LC302PU16CT targets embedded and communications applications that benefit from a single-chip multiprotocol controller with low-power modes and flexible boot/host interfaces.

Key Features

• Core and Performance Static M68000 core supporting an 8/16-bit M68000 family system with a maximum clock speed of 16 MHz, suitable for embedded control and protocol handling.
• Memory and DMA On-chip 1,152‑byte dual-port RAM and an Independent Direct Memory Access (IDMA) controller provide efficient data movement and low-latency inter-module communication.
• Communications and Co-processor Integrated communications processing including a RISC main controller and two full-duplex Serial Communications Controllers (SCCs) supporting HDLC/SDLC, UART and BISYNC protocols, plus autobaud support.
• Timers and System Reliability Three timers including a watchdog timer and a Periodic Interrupt Timer (PIT) provide system timing, watchdog protection and periodic wake-up capability.
• System Control and Boot Features programmable address mapping, four programmable chip-select lines with wait-state generator logic, glueless interface to EPROM/SRAM/Flash/EEPROM, and boot support for 8-bit mode with run-time switch to 16-bit mode.
• Clocking and Low-Power On-chip clock generator and PLL allow operation with 32 kHz or 4 MHz crystals and support low-power (standby) modes for reduced energy consumption in portable applications.
• Interfaces and I/O Parallel I/O ports (some with interrupt capability), interrupt controller with two modes of operation, and additional GCI interface provide flexible peripheral connectivity.
• Package and Electrical Supplied in a 100-LQFP (14×14 mm) surface-mount package; I/O voltage 5 V and operating temperature range 0 °C to 70 °C. RoHS compliant.

Typical Applications

• Embedded Communications Modules — Protocol handling and serial connectivity for HDLC/SDLC, UART or BISYNC links using the integrated SCCs and communications processor.
• Portable and Low-Power Devices — Suited to height-restricted, low-power applications (for example PCMCIA-type designs) where compact packaging and standby modes are required.
• Protocol Converters and Gateways — On-chip DMA, timers and dual-port RAM simplify data buffering and protocol bridging between host systems and serial networks.
• Control and Instrumentation — Use the M68000 core, PIO and timers for embedded control tasks, timing, and supervisory watchdog functions in instrumentation systems.

Unique Advantages

• Highly Integrated Multiprotocol Processor: Combines an M68000 core, communications processor, SCCs, DMA, timers and dual-port RAM to reduce BOM and PCB area.
• Compact Surface-Mount Package: 100-LQFP (14×14) package enables deployments in height-restricted and space-constrained applications.
• Flexible Boot and Memory Interface: Glueless interfacing to EPROM/SRAM/Flash/EEPROM with programmable chip-selects simplifies memory subsystem design and boot sequencing.
• Built-In Reliability Features: Watchdog timer, interrupt controller and DRAM refresh controller enhance system robustness and operational stability.
• Designed for Communications: Two full-duplex SCCs with protocol support (HDLC/SDLC, UART, BISYNC) and autobaud allow straightforward integration into serial networks.
• Low-Power and Clock Flexibility: On-chip PLL and clock generator with support for low-frequency crystals plus standby modes aid power-conscious designs.
