MC68EN360VR33L

The MC68EN360VR33L is a CPU32+ microprocessor delivering a single 32‑bit core operating at 33 MHz in a 357‑pin PBGA (25×25) surface‑mount package. Designed for embedded systems, this device integrates a communications‑oriented Communications Processor Module (CPM) and a suite of serial controllers to support complex protocol handling and network I/O.

With on‑chip DRAM controller support, integrated serial channels and DMA, and 5 V I/O, the MC68EN360VR33L targets embedded communications and control applications that require consolidated peripheral functionality and predictable operating characteristics across 0 °C to 70 °C.

Key Features

• Core and Performance — CPU32+ single 32‑bit core running at 33 MHz, providing a familiar CPU32 architecture for embedded software development.
• Voltage and Mounting — 5 V I/O logic levels with a surface‑mount 357‑pin PBGA (25×25) package for compact, board‑level integration.
• Communications Processor Module (CPM) — On‑chip CPM with a RISC controller and protocol support, designed to offload serial communications tasks and manage buffer descriptors for efficient data handling.
• Serial Interfaces — Multiple serial channels including four Serial Communications Controllers (SCCs), two Serial Management Controllers (SMCs) and one SPI, enabling versatile serial protocol connectivity and HDLC/SDLC support.
• Ethernet Support — Full 10 Mbps Ethernet/IEEE 802.3 support available on SCC1, providing an integrated network interface option for embedded networking designs.
• Memory and Bus — Support for dynamic bus sizing up to a 32‑bit data bus and DRAM controller options to interface with SRAM, EPROM, or Flash memory devices.
• Timers and DMA — Four general‑purpose timers (configurable as four 16‑bit or two 32‑bit timers) and two independent DMA controllers for high‑efficiency data transfers and precise timing control.
• System Integration and Diagnostics — System Integration Module features such as watchdog, bus monitoring, breakpoint logic and IEEE 1149.1 Test Access Port to aid system reliability and debug.
• Operating Range and Compliance — Commercial temperature operation from 0 °C to 70 °C and RoHS compliance for environmental conformance.

Typical Applications

• Embedded Communications Equipment — Ideal for modem controllers, protocol concentrators and communication gateways where on‑chip CPM and multiple serial channels accelerate packet handling and protocol offload.
• Network Interface Modules — Use SCC1 Ethernet capability and serial interfaces to implement 10 Mbps network endpoints and legacy serial‑to‑Ethernet bridges.
• Industrial Control and Automation — Integrate control, timing and serial I/O in compact embedded controllers that require deterministic timers and DMA for peripheral data movement.
• Protocol Conversion and Telecom — Support for HDLC/SDLC and multiple serial channels makes the device suited to protocol conversion, link termination and telecom interface modules.

Unique Advantages

• Highly integrated communications peripherals: On‑chip CPM plus SCC/SMC/SPI channels reduce external component count and simplify board design for serial and networked applications.
• Offloaded protocol processing: CPM with dedicated buffer descriptors enables efficient handling of serial protocols without continuous CPU intervention.
• Flexible memory interfacing: Dynamic bus sizing and DRAM controller support allow designers to match memory architectures (SRAM/EPROM/Flash) to application requirements.
• Deterministic I/O and timing: Multiple timers and independent DMA channels provide precise control and high‑throughput data movement for real‑time embedded tasks.
• Compact PBGA footprint: 357‑pin PBGA (25×25) package supports high pin density in space‑constrained embedded systems.
• Standards and environmental readiness: 10 Mbps Ethernet support on SCC1 and RoHS compliance align the device with common networking needs and regulatory expectations.
