MC68360AI25VL

The MC68360AI25VL is a CPU32+ microprocessor from the MC68360 QUICC family, implemented as a single 32-bit core running at 25 MHz in a 240-pin FQFP surface-mount package. It combines a CPU32+ core with an integrated communications processor module (CPM) and a broad set of on-chip peripherals targeted at communications and embedded controller applications.

Designed for controller and communications roles, the device integrates memory control, multiple serial channels, DMA, timers and a system integration module to simplify system design and reduce external component count while supporting standard 3.3 V I/O and commercial temperature operation.

Key Features

• Core — CPU32+ single 32-bit core operating at 25 MHz; complete static design supporting 0–33 MHz operation as described in the device family documentation.
• Memory — On-chip memory controller with support for DRAM (eight-bank controller) and glueless interfaces to common memory types; boot chip select available at reset with options for 8-, 16- or 32-bit memory widths.
• Communications Co-processor (CPM) — Integrated CPM for communications handling and offloading protocol tasks from the CPU core.
• Serial Interfaces — Multiple serial channels including four Serial Communications Controllers (SCCs), two Serial Management Controllers (SMCs) and one Serial Peripheral Interface (SPI) for diverse serial connectivity.
• Ethernet — Integrated 10 Mbps Ethernet interface (1 port) for basic network connectivity.
• Timers & DMA — Four general-purpose timers (configurable as four 16-bit or two 32-bit timers) and two independent DMA channels (IDMAs) for deterministic data movement and timing.
• System Integration — System Integration Module (SIM60) with bus monitor, breakpoint logic, periodic interrupt timer, on-chip bus arbitration and support for external masters and companion-mode operation.
• Package & Mounting — 240-lead Plastic Quad Flat Pack (240-FQFP, 32×32 mm footprint) intended for surface-mount assembly.
• Power & I/O — 3.3 V I/O supply level as specified in product data.
• Operating Range — Commercial temperature range: 0°C to 70°C.
• Compliance — RoHS compliant.

Typical Applications

• ISDN and Telecom Equipment — On-chip CPM, multiple serial channels and integrated timers make the device suitable for telephony and telecom controller functions.
• Mid-range Routers and LAN Switches — Integrated serial interfaces, DMA and an Ethernet port support packet handling and peripheral control in network equipment.
• Bridges and Network Gateways — The combination of CPU core, communications processors and memory controller enables protocol handling and buffering for gateway applications.
• Wireless Infrastructure — Communications-focused peripheral set and system integration features support base station and infrastructure controller tasks.

Unique Advantages

• Integrated communications peripherals: Four SCCs, two SMCs and SPI plus a CPM reduce external interface chips and simplify communications stack integration.
• Single-chip system controller: On-chip CPU, memory controller, timers, DMA and SIM60 lower BOM count and streamline PCB design.
• Flexible memory support: Eight-bank DRAM controller and glueless interfaces to common memory types provide versatile system memory options and boot-time configuration.
• Deterministic I/O and data movement: Dedicated IDMAs and multiple timers enable predictable data transfer and timing for embedded control tasks.
• Commercial temperature and surface-mount packaging: 240-FQFP surface-mount package and 0°C to 70°C operation match common industrial and communications product requirements.
• RoHS compliant: Facilitates use in modern assemblies requiring lead-free components.
