• Performance  20 MHz operating speed suitable for cost-sensitive, low-power embedded designs.
• Power Management  Static HCMOS design supports stopping the processor clock and low-power operation; typical current consumption cited as 0.5 µA in static standby and 15.0 mA in normal 3.3 V operation. Operates in 3.3 V or 5.0 V systems.
• Memory & I/O  DRAM controller support and memory-mapped I/O capability; architecture supports 56 instruction types and 14 addressing modes for flexible software implementation.
• Interfaces  Includes 10 Mbps Ethernet capability as specified and other embedded I/O suitable for portable and handheld systems.
• Package & Mounting  64-lead Quad Flat Pack (64-QFP) supplier package, 14 mm × 14 mm footprint, surface-mount mounting type.
• Operating Range  Rated for operation from 0 °C to 70 °C.
• Software Compatibility  Object-code compatible with the M68000 Family and pin-for-pin replacement compatibility with the MC68EC000 in QFP packages, enabling reuse of existing code and development tools.
• Regulatory  RoHS compliant.

Typical Applications

• Portable Consumer Electronics  Battery-operated handheld devices and electronic games can leverage the low standby current and compact QFP package for extended battery life and small PCB area.
• Personal Digital Assistants & Handheld Instruments  32-bit processing and DRAM controller support make it suitable for user-interface control and data handling in portable measuring equipment.
• Low-Power Embedded Controls  Static design and the ability to stop the processor clock support power-managed control systems in portable and stand-by sensitive applications.
• Networked Embedded Devices  10 Mbps Ethernet capability enables use in simple networked or connectivity-enabled embedded applications.

Unique Advantages

• Low Standby Consumption:  Typical 0.5 µA in static standby mode reduces battery drain for long-life portable products.
• Flexible Voltage Operation:  Supports both 3.3 V and 5.0 V systems, simplifying integration across different power domains.
• Static Architecture:  Clock-stop capability lets designers implement aggressive power-management strategies without special external circuitry.
• Software Reuse:  Object-code compatibility with the M68000 Family and pin-for-pin replacement with MC68EC000 allow reuse of existing code and development tools, reducing time to market.
• Compact Surface-Mount Package:  64-QFP (14 × 14 mm) surface-mount package minimizes PCB space while maintaining required I/O density.
• Embedded Connectivity:  Integrated 10 Mbps Ethernet support helps enable simple network-enabled applications without adding external MAC hardware.
