MC68302PV16VC

The MC68302PV16VC is a single-chip microprocessor built around the MC68000/MC68008 core with a closely coupled communications processor and system integration block. It provides a compact, integrated platform for embedded networking and communications designs.

Targeted at networking, ISDN and gateway applications, the device combines a 16 MHz MC68000-class core with a dedicated RISC communications processor and multiple on-chip peripherals to enable multi-protocol, concurrent communications in a surface-mount 144-LQFP package.

Key Features

• Core & Architecture  The MC68000/MC68008 microprocessor core paired with a separate RISC communications processor (CP) provides a split architecture for general processing and communications handling.
• Clock & Voltage  16 MHz operating speed with 3.3 V I/O supply voltage.
• Bus Width & Cores  Single-core implementation with an 8/16-bit bus width.
• Communications Engines  Three Serial Communications Controllers (SCCs) and two Serial Management Controllers (SMCs) for flexible channel management and protocol handling.
• Protocol Support  SCCs support HDLC/SDLC, Bisync, UART, DDCMP, Totally Transparent protocols and V.110 operation.
• DMA & Buffering  Six serial DMA channels, capability to handle multiple buffers/frames without M68000 intervention, and an independent IDMA controller.
• On-chip Memory  1,152 bytes of dual-port RAM and a DRAM controller with refresh support for external memory management.
• System Control & Reliability  Interrupt controller with two modes, hardware watchdog, freeze control for debugging, disable CPU logic option, and low-power standby modes.
• Timers & I/O  Three timers including a software watchdog timer, parallel I/O ports (some with interrupt capability), and four programmable chip-select lines with wait-state logic.
• Interfaces  Flexible physical interfaces accessible by SCCs for Inter-chip Digital Link (IDL), General Circuit Interface (GCI), PCM, and Non-multiplexed Serial Interface (NMSI); includes a Serial Communication Port (SCP).
• Package & Mounting  144-LQFP surface-mount package, supplier device package dimension 20×20 mm.
• Operating Range & Compliance  Rated for 0°C to 70°C operating temperature and RoHS compliant.

Typical Applications

• ISDN Equipment  Multi-protocol support and dedicated communications controllers make the device suitable for ISDN basic rate and terminal adapter designs.
• Data Concentrators  On-chip DMA, multiple SCCs and dual-port RAM enable high-throughput channel aggregation and buffering.
• Modems  Integrated communications processor and protocol support including UART and HDLC/SDLC are aligned with modem front-end tasks.
• Line Cards  Programmable chip-selects, parallel I/O and serial interfaces support line-card functions and peripheral control.
• Network Bridges & Gateways  Concurrent protocol operation and flexible interface options suit bridging and gateway functions in communication networks.

Unique Advantages

• Highly integrated processor + communications engine: A combined MC68000-class core and RISC communications processor reduce the need for separate controller ICs and simplify architecture for communications products.
• Multi-protocol communications support: Built-in SCCs and SMCs with HDLC/SDLC, Bisync, UART, DDCMP and V.110 support enable versatile protocol handling on-chip.
• Efficient DMA and buffering: Six serial DMA channels, an IDMA controller and the ability to manage multiple buffers/frames without host core intervention improve data throughput and offload the main CPU.
• On-chip system resources: Dual-port RAM (1,152 bytes), timers, interrupt controller and DRAM refresh controller provide essential system infrastructure on-chip for compact designs.
• Debug and reliability features: Hardware watchdog, freeze control for debugging and disable-CPU capability assist in system reliability and development workflows.
• Standard surface-mount package: 144-LQFP (20×20 mm) enables straightforward PCB integration for compact embedded boards.
