MC68E360VR25VLR2

The MC68E360VR25VLR2 is a single-core CPU32+ microprocessor IC operating at 25 MHz with a 32‑bit core optimized for embedded communications tasks. It combines a CPU32+ core with a dedicated Communications Processor Module (CPM) and multiple serial controllers to address communications‑centric embedded designs.

Designed for systems requiring integrated serial connectivity, DMA support and flexible memory interfacing, the device targets embedded and communications applications where integration and deterministic I/O are important.

Key Features

• Core  CPU32+ 32‑bit processor core; documented 4.5 MIPS at 25 MHz and background debug mode for development and troubleshooting.
• Memory and Bus  Up to 32‑bit data bus with dynamic bus sizing for 8/16 bit operation and up to 32 address lines (at least 28 available). Boot chip select and options for 8/16/32‑bit memory interface are supported.
• Communications Processor Module (CPM)  On‑chip CPM RISC controller with support for buffer descriptors (224) and commands to manage continuous transmit/receive and efficient serial operations.
• Serial Channels  Multiple serial channels: four SCCs, two SMCs and one SPI (seven serial channels total), enabling diverse serial protocol support and multitasking communications.
• Ethernet and SCCs  SCC architecture supports Ethernet/IEEE 802.3 optional operation and HDLC/SDLC on multiple channels; SCC1 Ethernet 10 Mbps noted in series documentation.
• Timers and DMA  Four general‑purpose timers (configurable as four 16‑bit or two 32‑bit timers) and two independent DMAs with buffer chaining and auto buffer modes for efficient data movement.
• System Integration & Debug  System Integration Module (SIM60) features bus monitors, software watchdog, breakpoint logic and IEEE 1149.1 test access port for on‑chip diagnostics and system control.
• I/O and Power  3.3 V I/O signaling and surface mount 357‑PBGA (25×25) supplier package for compact board placement.
• Operating Range and Compliance  Commercial operating temperature range of 0 °C to 70 °C and RoHS‑compliant status.

Typical Applications

• Network and Communications Controllers  Leverages the CPM and multiple serial channels for protocol handling, packet processing and serial multiplexing in embedded network equipment.
• Embedded Gateways  Integrates serial interfaces and DMA to bridge heterogeneous interfaces and offload serial protocol processing from a host CPU.
• Industrial Control Systems  Provides deterministic timers, DMA and serial interfaces for supervisory control, telemetry and serial device integration in commercial industrial applications.

Unique Advantages

• Highly integrated communications subsystem: On‑chip CPM plus multiple SCC/SMC/SPI channels reduce external logic and simplify board design for serial and protocol‑heavy applications.
• Deterministic data movement: Dual independent DMAs with buffer chaining and auto buffer modes enable efficient, low‑overhead transfers for real‑time data streams.
• Flexible memory interfacing: Support for dynamic bus sizing and boot chip select for 8/16/32‑bit memories eases system memory design and boot options.
• Compact surface‑mount package: 357‑PBGA (25×25) package allows high‑density PCB layouts while retaining extensive on‑chip functionality.
• Development and debug support: Background debug mode, breakpoint logic and IEEE 1149.1 TAP facilitate development, testing and in‑system diagnostics.
• Standards‑aware communications: SCCs support HDLC/SDLC and optional Ethernet/IEEE 802.3 operation, enabling a wide range of serial network protocols.
