MC68EN360VR25L

The MC68EN360VR25L is a CPU32+ microprocessor from the MC68 series featuring a single 32‑bit core running at 25 MHz. Engineered as an integrated communications controller, it combines a CPU32+ core with dedicated communications subsystems suited for embedded controller and networking-oriented applications.

With on‑chip communications peripherals and a compact 357‑pin PBGA (25×25) package, this device targets designs that require integrated serial channels, DMA and memory interfaces while operating from a 5 V IO domain within a 0 °C to 70 °C temperature range.

Key Features

• CPU Core — CPU32+ at 25 MHz: Single 32‑bit CPU32+ core delivering approximately 4.5 MIPS at 25 MHz, with byte‑misaligned addressing and background debug mode.
• Bus and Memory Interface: Up to 32‑bit data bus with dynamic sizing for 8/16 bits and up to 32 address lines; supports DRAM controllers and boot chip select options for 8/16/32‑bit memory.
• Communications Processor Module (CPM): On‑chip RISC communications controller with 224 buffer descriptors, continuous mode support and commands for efficient serial channel handling.
• Serial Channels and Ethernet: Four SCCs plus additional serial channels (SMCs and SPI); Ethernet (IEEE 802.3) 10 Mbps support available on SCC1 for the EN360 variant.
• DMA and Timers: Two independent DMAs with buffer chaining and auto buffer modes for efficient transfers; four general‑purpose timers configurable as four 16‑bit or two 32‑bit timers.
• System Integration Module (SIM60): On‑chip bus monitor, double bus fault monitor, spurious interrupt monitor, software watchdog, periodic interrupt timer, clock synthesizer and breakpoint logic; includes IEEE 1149.1 test access port.
• Package and Mounting: 357‑PBGA (25×25) supplier package, surface‑mount, compact footprint for space‑constrained embedded designs.
• Operating Conditions and Compliance: 5 V IO supply and operating temperature range of 0 °C to 70 °C; RoHS compliant.

Typical Applications

• Networking and Communications Equipment: Integrated SCCs, CPM and optional 10 Mbps Ethernet make this device suitable for protocol handling, gateway and communications controller roles.
• Embedded Controllers: Single‑chip integration of CPU, DMA, timers and serial peripherals supports compact controllers for industrial and OEM embedded systems.
• Legacy Serial and HDLC-Based Systems: Multiple SCC channels with HDLC/SDLC support enable use in systems requiring serial protocol management and HDLC bus implementations.

Unique Advantages

• Integrated Communications Subsystem: CPM plus multiple SCCs and serial channels reduce external peripheral requirements for communications‑centric designs.
• Flexible Memory and DMA Support: 32‑bit bus with dynamic sizing, DRAM controller support and two IDMAs enable efficient memory access and high‑throughput data transfers.
• On‑Chip System Management: SIM60 features such as watchdog, bus monitors and breakpoint logic simplify system reliability and debug implementation.
• Ethernet‑Enabled Variant: The EN360 designation includes optional 10 Mbps Ethernet on SCC1, allowing direct network connectivity without additional MAC controllers.
• Compact Surface‑Mount Packaging: 357‑pin PBGA provides high pin density in a compact footprint suitable for space‑constrained boards.
• Regulatory and Assembly-Friendly: RoHS compliance and standard surface‑mount PBGA packaging support modern manufacturing and environmental requirements.
