MC68SEC000AE20

The MC68SEC000AE20 is a static embedded microprocessor based on the EC000 core, delivering a single 32‑bit processing core at 20 MHz in a compact 64‑lead LQFP (10 × 10 mm) surface‑mount package. It targets low‑power embedded designs where small footprint and energy efficiency are primary requirements.

Designed for battery‑operated and portable consumer applications, the device combines a 32‑bit architecture, low standby and operating currents, and dual‑voltage operation to provide a balance of performance and power efficiency for embedded systems.

Key Features

• Core and Architecture EC000 core with a single 32‑bit processor; includes eight 32‑bit address registers and eight 32‑bit data registers, supporting the M68000 family instruction set and object‑code compatibility.
• Performance 20 MHz operating speed as specified for this part number, with the EC000 family offering multiple speed options in the series.
• Memory and Bus Supports DRAM controllers; 16‑Mbyte linear addressing range and memory‑mapped I/O for straightforward system integration.
• Low Power Static HCMOS design with typical 0.5 µA current in static standby and ~15.0 mA in normal 3.3 V operation; static implementation allows stopping the processor clock for power management.
• Voltage Operates in either 3.3 V or 5.0 V systems, enabling use in mixed‑voltage applications.
• Interfaces Includes support for 10 Mbps Ethernet (1) and standard memory‑mapped I/O connectivity; graphics acceleration is not included.
• Package and Mounting 64‑lead LQFP (10 × 10 mm) surface‑mount package, ideal for compact board layouts and portable product designs.
• Operating Range and Compliance Rated for 0 °C to 70 °C operation and RoHS compliant.

Typical Applications

• Portable Consumer Devices — Battery‑operated handheld products benefit from the device’s low standby current and compact package to extend runtime and save board space.
• Personal Digital Assistants and Handhelds — 32‑bit EC000 architecture and object‑code compatibility with the M68000 family enable reuse of established code and toolchains for PDAs and similar devices.
• Portable Measurement Equipment — Low power consumption and DRAM controller support suit portable test and measurement instruments requiring efficient processing.
• Electronic Games and Consumer Electronics — Small footprint and single‑chip 32‑bit processing provide a cost‑effective option for embedded game controllers and consumer applications.

Unique Advantages

• Very Low Standby Current: Typical 0.5 µA in static standby mode reduces battery drain for long shelf and standby life.
• Static Design with Clock Stop: Ability to stop the processor clock allows flexible power management strategies in software or system control.
• Dual‑Voltage Operation: Support for 3.3 V or 5.0 V systems eases integration into existing designs without extensive power‑rail redesign.
• Pin‑for‑Pin Replacement Compatibility: Direct replacement for the MC68EC000 in the plastic QFP package facilitates upgrades or redesigns with minimal hardware change.
• Code Compatibility with M68000 Family: Object‑code compatibility lets teams leverage existing codebases and third‑party development tools.
• Compact Surface‑Mount Package: 64‑lead LQFP (10 × 10 mm) minimizes PCB area while supporting standard SMT assembly.
