MC68EN360ZQ25VL

The MC68EN360ZQ25VL is a single-core CPU32+ microprocessor from NXP Semiconductors, operating at 25 MHz with a 32-bit core architecture. Designed for embedded controller and communications-focused applications, it integrates a Communications Processor Module (CPM) and multiple serial controllers to simplify protocol handling and system integration.

This device targets embedded and communications markets where integrated serial interfaces, on-chip system management, and a compact 357-PBGA (25×25) surface-mount package are valued. Key value comes from its integrated communications peripherals, flexible memory/bus support and on-chip system reliability features.

Key Features

• CPU Core: CPU32+ single 32-bit core running at 25 MHz delivering approximately 4.5 MIPS at 25 MHz as specified for the CPU32+ implementation.
• Bus and Memory Support: Up to 32-bit data bus with dynamic bus sizing for 8- and 16-bit operation and up to 32 address lines; supports external memory types including SRAM, EPROM, Flash and DRAM with multiple CAS/WE/OE signals and boot chip select options.
• Communications Processor Module (CPM): Integrated RISC-based CPM with 224 buffer descriptors and support for continuous transmit/receive modes to offload serial protocol processing.
• Serial Interfaces: Four Serial Communications Controllers (SCCs), two Serial Management Controllers (SMCs) and one SPI; SCC1 offers optional Ethernet (IEEE 802.3) support at full 10 Mbps on the MC68EN360 variant.
• DMA and Timers: Two independent DMAs with buffer chaining, auto buffer modes and efficient packing; four general-purpose timers configurable as four 16-bit or two 32-bit timers with gate mode.
• System Integration Module (SIM60): On-chip features including bus monitor, double bus fault monitor, spurious interrupt monitor, software watchdog, periodic interrupt timer, clock synthesizer and breakpoint logic.
• Debug and Test: Background Debug Mode and IEEE 1149.1 Test Access Port for on-chip debug and boundary-scan testing.
• Power and Packaging: 3.3 V IO supply, surface-mount 357-PBGA (25×25) package, and a Low Power Stop Mode for reduced power operation.
• Operating Range and Compliance: Rated for 0 °C to 70 °C operation and RoHS compliant.

Typical Applications

• Embedded Communications Controllers: Offload protocol handling and serial channel management using the integrated CPM and multiple SCC/SMC channels.
• Network Interface Modules: Implement 10 Mbps Ethernet on SCC1 and manage HDLC/SDLC channels for networked embedded systems.
• Industrial and Control Systems: Use on-chip timers, DMA and robust bus monitoring features for deterministic control and data movement.

Unique Advantages

• Highly integrated communications capability: Multiple SCCs, SMCs, SPI and a CPM reduce external component count and simplify protocol implementations.
• Flexible memory and bus options: Dynamic bus sizing and support for various external memory types enable straightforward interface to existing memory designs.
• On-chip system reliability features: Built-in watchdog, bus fault monitors and spurious interrupt monitoring help detect and recover from system faults.
• Compact surface-mount package: 357-PBGA (25×25) package provides a compact footprint for space-constrained board designs.
• Standard voltage and industry compliance: 3.3 V IO and RoHS compliance simplify integration into modern embedded systems.
