MC68EN360CVR25L

The MC68EN360CVR25L is a CPU32+ microprocessor in the MC68 series, featuring a single 32-bit core running at 25 MHz and purpose-built communications peripherals. It integrates a Communications Processor Module (CPM) and multiple serial controllers, making it well suited for embedded communications and industrial control applications.

Designed for industrial qualification and surface-mount assembly, the device delivers a combination of integrated I/O, bus flexibility and on-chip system features to simplify designs that require deterministic serial communications and protocol offload.

Key Features

• Core & Performance CPU32+ processor core (32-bit) operating at 25 MHz; documented operation at up to 25 MHz with a static design that supports 0–25 MHz operation and 4.5 MIPS at 25 MHz.
• Bus and Memory Up to 32-bit data bus with dynamic bus sizing for 8- and 16-bit accesses; support for external memory types (SRAM, EPROM, Flash EPROM) and configurable boot chip select for reset-time boot options.
• Communications & Co-Processing On-chip Communications Processor Module (CPM) with a RISC controller and 224 buffer descriptors for serial channel offload; four Serial Communications Controllers (SCCs), two Serial Management Controllers (SMCs) and one SPI channel provide seven serial channels in total. SCC1 optionally supports 10 Mbps Ethernet/IEEE 802.3 (available on MC68EN360 variants).
• Timers & DMA Four general-purpose timers (configurable as four 16-bit or two 32-bit timers) and two independent DMA controllers with buffer chaining and auto-buffer modes for efficient data movement.
• System Integration & Debug System Integration Module (SIM60) including bus monitor, watchdog, breakpoint logic, IEEE 1149.1 Test Access Port and clock synthesizer; background debug mode and support for slave mode or companion operation with external processors.
• Interfaces & Protocol Support Built-in support for HDLC/SDLC on all four SCC channels, HDLC bus, AppleTalk and additional SCC-based interfaces useful for protocol handling and embedded networking.
• Power, Packaging & Environment 5 V I/O voltage, industrial qualification, RoHS compliant, surface-mount 357-PBGA package (25 × 25 mm), and an operating temperature range of −40 °C to 85 °C.
• Graphics & Specialty No graphics acceleration—device focus is on communications, control and protocol processing rather than graphical tasks.

Typical Applications

• Embedded Communications Controllers Use the integrated CPM and multiple SCC/SMC channels to offload serial protocol handling and concentrate host cycles on application logic.
• Industrial Control Systems Industrial-rated temperature range and integrated timers, DMA and watchdog features make the device suitable for deterministic control and monitoring tasks.
• Network Interface & Protocol Gateways SCC channels with HDLC/SDLC support and optional 10 Mbps Ethernet on SCC1 enable gateway and interface applications for legacy and embedded networks.
• Peripheral Offload Modules Leverage the CPM and DMA to implement dedicated peripheral controllers that reduce host CPU load and simplify BOM for communication-centric modules.

Unique Advantages

• Integrated Communications Subsystem: The on-chip CPM and multiple serial controllers provide hardware-level support for protocol processing, reducing external logic and software complexity.
• Flexible Memory and Bus Options: 32-bit data bus with dynamic sizing and multiple memory control signals (CAS/WE/OE lines) simplify interfacing to various external memory types and boot configurations.
• Deterministic I/O and DMA: Independent DMA channels, buffer chaining and efficient packing enable high-throughput transfers with predictable timing for real-time applications.
• Industrial-Ready Packaging: RoHS-compliant 357-PBGA (25 × 25 mm) surface-mount package and −40 °C to 85 °C operating range support deployment in industrial environments.
• On-Chip System Monitoring and Debug: Built-in watchdog, breakpoint logic, IEEE 1149.1 test port and background debug mode assist development, test and long-term reliability.
