MC68302PV20C

The MC68302PV20C is an integrated microprocessor intended for embedded networking and communications applications. It combines an MC68000/MC68008 core with a system integration block (SIB) and a dedicated communications processor (RISC CPM) to provide a single-chip solution for multi-protocol communications designs.

With a 20 MHz core speed, built-in serial controllers and DMA, and a 144-LQFP (20×20) surface-mount package, the device targets systems such as ISDN equipment, modems, line cards and gateways where integrated communications processing and flexible interface support are required.

Key Features

• Core MC68000/MC68008 microprocessor core (may be disabled for peripheral use) operating at 20 MHz.
• Communications Processor (CP/CPM) Separate RISC communications processor handling multi-channel communications tasks, enabling concurrent protocol operation.
• Serial Controllers Three full-duplex Serial Communications Controllers (SCCs) and two Serial Management Controllers (SMCs) supporting interfaces such as IDL and GCI.
• Protocol Support SCCs support HDLC/SDLC, Bisync, UART, DDCMP, Totally Transparent protocols and V.110 for flexible protocol implementation.
• DMA and Buffering Six serial DMA channels for SCCs and capability to send/receive multiple buffers/frames without M68000 core intervention; independent Direct Memory Access (IDMA) controller included.
• On-chip Memory and Controllers On-chip 1,152‑byte dual-port RAM, DRAM refresh controller and four programmable chip-select lines with wait-state logic.
• System and I/O Interrupt controller with two modes, multiple parallel I/O ports (some with interrupt capability), three timers including a software watchdog, and a hardware watchdog for bus activity monitoring.
• Packaging and Power 144‑LQFP (20×20) surface-mount package; I/O voltage 5 V; operating temperature range 0 °C to 70 °C.
• Compliance RoHS compliant.

Typical Applications

• ISDN Equipment Configurable communications architecture supports interfaces used in ISDN basic rate and terminal adapter applications.
• Data Concentrators Integrated serial controllers, DMA channels and on-chip dual-port RAM support multi-channel data handling and buffering.
• Modems and Line Cards Built-in communications processor and protocol support enable implementation of serial and synchronous telecom protocols on a single device.
• Network Bridges and Gateways Concurrent protocol operation and multiple serial interfaces facilitate bridging and gateway functions in embedded network equipment.

Unique Advantages

• Highly integrated architecture: MC68000/MC68008 core combined with SIB and a dedicated communications processor reduces external component requirements by consolidating CPU, communications and system functions on-chip.
• Flexible multi-protocol support: SCCs and SMCs support a broad set of serial protocols (HDLC/SDLC, Bisync, UART, DDCMP, Totally Transparent, V.110) for varied communications roles.
• Dedicated DMA and buffering: Six serial DMA channels and on-chip dual-port RAM enable efficient data movement and reduce host CPU intervention for frame/buffer handling.
• Robust system control: Interrupt controller, watchdog timers, DRAM refresh controller and programmable chip-selects provide system-level features needed for reliable embedded designs.
• Industry tooling and documentation: Series documentation and third-party tools support simplify development and integration for deployed systems.
