MC68360AI25L

The MC68360AI25L is a CPU32+ 32-bit microprocessor in a 240-FQFP (32×32) surface-mount package, featuring a single core running at 25 MHz. It is part of the MC68360 QUICC family, a one-chip integrated microprocessor and peripheral combination designed for controller and communications-focused embedded applications.

With on-chip communications acceleration, multiple serial channels and flexible memory/bus options, the MC68360AI25L targets embedded designs that require integrated serial protocol handling, DMA support and system-level integration while operating from 5 V I/O and within a 0 °C to 70 °C range.

Key Features

• Core and Performance — CPU32+ 32-bit core operating at 25 MHz; datasheet indicates 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- and 16-bit operation and up to 32 address lines (at least 28 always available). Supports SRAM, EPROM and Flash EPROM memory types and provides a boot chip select at reset.
• Communications Processor Module (CPM) — On-chip RISC-based CPM with 224 buffer descriptors and support for continuous transmit/receive modes and advanced communication commands to offload serial data handling.
• Serial Interfaces — Seven serial channels (four SCCs, two SMCs and one SPI) for diverse serial connectivity; supports Ethernet/IEEE 802.3 full 10 Mbps on one channel (SCC1) as provided in product specifications.
• DMA and Timers — Two independent IDMAs with 32-bit internal/external transfers, buffer chaining and auto-buffer modes; four general-purpose timers configurable as four 16-bit or two 32-bit timers.
• System Integration and Reliability — System Integration Module (SIM60) providing bus monitor, double bus fault monitor, spurious interrupt monitor, software watchdog, periodic interrupt timer, breakpoint logic and IEEE 1149.1 test access port.
• Package and Environmental — 240-FQFP (32×32) surface-mount package, 5 V I/O, operating temperature 0 °C to 70 °C, and RoHS compliant.

Typical Applications

• Communications Equipment — Dedicated communications controller for handling multiple serial channels and continuous protocol streams using the CPM and on-chip SCC/SMC interfaces.
• Embedded Control Systems — One-chip microprocessor plus peripherals simplifies embedded controller designs that require timers, DMA and flexible memory interfacing.
• Protocol Offload / Interface Modules — Hardware support for HDLC/SDLC and an available 10 Mbps Ethernet channel make the device suitable for protocol processing and network interface implementations.
• Development and Test Platforms — Background debug mode, breakpoint logic and IEEE 1149.1 test access provide on-chip debug and testability for development environments.

Unique Advantages

• Highly integrated communications-centric design: CPU32+ core with CPM and multiple serial controllers reduces external components and simplifies board design.
• Memory and bus flexibility: 32-bit bus with dynamic sizing, multiple memory type support and boot chip select enables varied memory configurations and legacy interfacing.
• Offloaded serial processing: CPM RISC controller plus IDMAs and buffer descriptor support handle protocol-level data transfers, freeing the main CPU for application tasks.
• Comprehensive system diagnostics: On-chip SIM60 features including watchdog, fault monitors and breakpoint logic improve system robustness and debug capability.
• Surface-mount RoHS-compliant package: 240-FQFP (32×32) packaging supports modern assembly processes and environmental compliance.
• Diverse serial channel mix: Four SCCs, two SMCs and one SPI provide flexibility for multi-protocol serial interfacing, including an optional 10 Mbps Ethernet channel.
