MC68SEC000CAA20

The MC68SEC000CAA20 is a low-power embedded microprocessor from the MC68 series featuring an EC000 core implemented as a static 32-bit processor running at 20 MHz. Packaged in a 64-lead QFP (14×14 mm) surface-mount package and qualified for industrial temperature ranges, it is designed for compact, battery-aware embedded systems.

Its architecture and power-management features make it well suited to handheld and portable applications that require established M68000-family code compatibility, efficient 32-bit processing and small footprint integration.

Key Features

• Core and Architecture — EC000 core with a single 32-bit processor; eight 32-bit address registers and eight 32-bit data registers provide a classic M68000-style architecture optimized for high-level languages and existing toolchains.
• Performance — 20 MHz operating frequency; supports the MC68SEC000 family speed options including 10/16/20 MHz as referenced in product documentation.
• Memory and Addressing — 16 Mbyte linear addressing range and memory-mapped I/O support with 14 addressing modes and a broad instruction set (56 instruction types) for flexible system design.
• Low-Power Operation — Static HCMOS design allows stopping the processor clock for power management; typical current consumption cited as 0.5 µA in static standby and 15.0 mA in normal 3.3 V operation (datasheet values).
• Voltage Compatibility — Designed to operate in either 3.3 V or 5.0 V systems, enabling integration into mixed-voltage platforms.
• Interfaces and Controllers — Integrated DRAM controller support and a 10 Mbps Ethernet interface (1) enable common embedded connectivity and memory options.
• Package and Mounting — 64-lead plastic Quad Flat Pack (QFP), supplier package 64-QFP (14×14 mm); surface-mount for compact PCB layouts.
• Environmental and Qualification — Industrial qualification with an operating temperature range of −40 °C to 85 °C; RoHS compliant.

Typical Applications

• Portable Consumer Devices — Battery-operated handheld products and electronic games benefit from the static low-power design and small package footprint.
• Personal Digital Assistants & Handheld Instrumentation — Low standby current and 32-bit processing make the device suitable for compact PDAs and portable measuring equipment.
• Embedded Control Systems — Industrial embedded controllers that require industrial temperature qualification and DRAM interfacing can leverage the MC68SEC000CAA20.
• Networked Embedded Nodes — Systems needing basic Ethernet connectivity at 10 Mbps can integrate the on-chip Ethernet interface for simple networked functions.

Unique Advantages

• Static, Low-Power Design: Stop-the-clock static architecture enables extremely low standby current for extended battery life and power-sensitive deployments.
• Established M68000 Compatibility: Object-code compatibility with the M68000 family and documented pin compatibility with EC000 derivatives reduce software porting effort and leverage existing toolchains.
• Flexible Voltage Operation: Support for 3.3 V or 5.0 V systems simplifies integration into a variety of platform voltage domains.
• Industrial Temperature Range: Rated for −40 °C to 85 °C operation to meet demanding environmental conditions in industrial and portable applications.
• Compact Surface-Mount Package: 64-QFP (14×14 mm) offers a small footprint for space-constrained PCBs while maintaining accessible pinout for system I/O and memory.
