MC68SEC000AA20R2

The MC68SEC000AA20R2 is a single-core, 32-bit microprocessor based on the EC000 architecture, supplied in a 64-lead QFP (14 × 14 mm) surface-mount package. This part is a low-power static embedded processor running at 20 MHz and is suited for compact, battery-powered and portable embedded applications.

Designed for low-power operation, the MC68SEC000 family supports both 3.3 V and 5.0 V systems and offers object-code compatibility with the M68000 family, enabling reuse of existing code and development tools.

Key Features

• Core & Architecture  EC000 single-core 32-bit architecture with eight 32-bit address registers and eight 32-bit data registers for efficient 32‑bit processing.
• Performance  Specified for 20 MHz operation for this part number; the MC68SEC000 family supports 10/16/20 MHz speeds in total.
• Power Management  Static design with low-power modes: typical 0.5 µA current in static standby at 3.3 V and typical 15.0 mA in normal 3.3 V operation. Operates at 3.3 V or 5.0 V.
• Memory & Addressing  16 Mbyte linear addressing range with memory-mapped I/O and support for DRAM controllers.
• Interfaces  Ethernet noted at 10 Mbps (1); practical interface capability for networked embedded designs.
• Instruction Set  56 instruction types, operations on five main data types and 14 addressing modes to support a variety of software needs.
• Package & Mounting  Supplied in a 64‑lead QFP (14 × 14 mm) surface-mount package; the MC68SEC000 family is also available in a thin QFP option per product documentation.
• Operating Range & Compliance  Rated for 0 °C to 70 °C operation and RoHS compliant.
• Graphics & Integration  No graphics acceleration; optimized for control and data-processing tasks in embedded systems.

Typical Applications

• Portable Consumer Devices  Battery-operated handheld products where low standby current and compact packaging extend battery life and minimize PCB area.
• Personal Digital Assistants & Handheld Instruments  Control and application processing in PDAs and portable measuring equipment that benefit from static operation and 32‑bit processing.
• Electronic Games & Toys  Embedded control and user-interface processing in electronic games and similar consumer electronics.
• Embedded Networked Devices  Simple networked embedded products that can utilize the documented 10 Mbps Ethernet capability.

Unique Advantages

• Low-power static operation: The static EC000 design enables extremely low standby current (typical 0.5 µA at 3.3 V), reducing power draw in sleep modes.
• Dual-voltage flexibility: Operates at 3.3 V or 5.0 V, allowing integration into a range of system power architectures.
• Code compatibility with M68000 family: Object-code compatibility speeds software reuse and leverages an established ecosystem of development tools.
• Pin-for-pin replacement path: Family compatibility with the MC68EC000 simplifies hardware upgrades and migration.
• Compact surface-mount package: 64‑lead QFP (14 × 14 mm) provides a small footprint for space-constrained PCBs.
• Standards-conscious supply: RoHS compliance supports environmentally conscious designs.
