MC68360VR25L

The MC68360VR25L is a 32-bit CPU32+ microprocessor IC in the MC68360 QUICC family, featuring a single CPU32+ core operating at 25 MHz. It combines a general-purpose 32-bit processor with a communications-focused peripheral set, making it well suited for embedded controller and communications-centric applications.

This device integrates on-chip communications management, DMA, timers and a flexible memory interface to deliver an integrated solution for designs that require multiple serial channels, protocol handling and deterministic on-chip resources.

Key Features

• Core Single CPU32+ 32-bit core at 25 MHz (approximately 4.5 MIPS at 25 MHz), with background debug mode and byte-misaligned addressing.
• Memory and Bus Up to 32-bit data bus with dynamic bus sizing for 8/16-bit accesses and up to 32 address lines; supports SRAM, EPROM and Flash memory types and includes a DRAM controller.
• Communications Processor Module (CPM) On-chip CPM with a RISC controller and support for 224 buffer descriptors to offload serial protocol handling and continuous mode transmission/reception.
• Serial Interfaces Multiple serial channels—four SCCs, two SMCs and one SPI—providing versatile serial connectivity; one channel supports 10 Mbps Ethernet (as specified).
• DMA and Timers Two independent IDMAs with buffer chaining and auto-buffer modes for efficient transfers, plus four general-purpose timers (configurable as four 16-bit or two 32-bit timers).
• System Integration and Debug Integrated SIM60 features including watchdog, clock synthesizer, bus and interrupt monitors, breakpoint logic and an IEEE 1149.1 test access port.
• Package, Power and Environment 357-PBGA surface-mount package (357-BBGA footprint), 25×25 mm supplier device package, 5 V I/O voltage, operating temperature range 0 °C to 70 °C, RoHS compliant.

Typical Applications

• Communications Controllers Embedded systems that require integrated protocol handling and multiple serial channels can leverage the CPM and SCC/SMC interfaces to offload communications tasks.
• Network Interfaces and Gateways Designs that need 10 Mbps Ethernet support on a dedicated channel and HDLC/SDLC framing can use the device’s serial and CPM features for protocol processing.
• Embedded Control Systems Single-chip controller applications benefitting from integrated DMA, timers and a 32-bit CPU for real-time control and data movement tasks.

Unique Advantages

• Highly integrated communications hardware: On-chip CPM and multiple serial controllers reduce external components and simplify board-level design.
• Offloaded protocol processing: CPM with buffer descriptor support and continuous mode transmission/reception reduces CPU overhead for serial communications.
• Flexible memory support: Dynamic bus sizing and support for 8/16/32-bit memory configurations plus DRAM controller enable diverse memory architectures and boot options.
• Efficient data movement: Two independent IDMAs with packing, buffer chaining and auto-buffer modes accelerate bulk transfers and peripheral data handling.
• System-level test and reliability: SIM60 features—including watchdog, bus monitors and IEEE 1149.1 TAP—help improve testability and system robustness.
• Manufacturing-ready package and compliance: 357-PBGA surface-mount package with 5 V I/O and RoHS compliance for standard production processes.
