MC68SEC000FU20

The MC68SEC000FU20 is an MC68 series static embedded microprocessor featuring the EC000 core implemented as a single 32-bit processor running at 20 MHz. It is engineered for low-power, compact embedded systems and supports both 3.3V and 5.0V operation.

Typical use cases include portable and battery-powered consumer devices and handheld instruments where power efficiency, a small package footprint, and established software compatibility are important design drivers.

Key Features

• Core and Architecture — EC000 core with a single 32-bit processor; internal architecture includes eight 32-bit address registers and eight 32-bit data registers, supporting a 16 Mbyte linear addressing range.
• Performance — 20 MHz operating frequency for responsive control and processing in embedded applications; supports the established M68000 family instruction set and object-code compatibility with other M68000 Family products.
• Power Management — Static HCMOS design enabling the processor clock to be stopped for low-power operation; documented low-power behavior includes very low standby current and reduced normal-mode current at 3.3V.
• Memory & I/O — DRAM controller support and memory-mapped I/O capability; architecture implements 56 instruction types and 14 addressing modes for flexible software design.
• Connectivity — Ethernet capability listed as 10Mbps (1).
• Package & Mounting — 64-pin Quad Flat Pack (64-QFP) supplier package, 14 × 14 mm footprint; surface-mount mounting type optimized for compact PCB layouts.
• Operating Range — Specified operating temperature range of 0 °C to 70 °C for standard commercial environments.
• Software & Ecosystem — Object-code compatibility across the M68000 Family and pin-for-pin compatibility with MC68EC000 support reuse of existing development tools and software.

Typical Applications

• Handheld Consumer Electronics — Low-power static design and small 64-QFP footprint enable battery-operated electronic games and portable entertainment devices.
• Personal Digital Assistants & Portable Instruments — 3.3V/5.0V operation and low standby current make the device suitable for PDAs and portable measuring equipment where battery life matters.
• Battery-Operated Devices — Static implementation with the ability to stop the processor clock supports designs that require aggressive power management to extend battery life.

Unique Advantages

• Low-power static design: Static HCMOS architecture and the ability to stop the processor clock enable minimal standby current and improved power management for battery-powered products.
• Flexible voltage operation: Operates in either 3.3V or 5.0V systems, allowing integration into a range of existing power architectures.
• Established software compatibility: Object-code compatibility with the M68000 Family and pin-for-pin replacement for MC68EC000 reduce software redevelopment time and leverage existing toolchains.
• Compact surface-mount package: 64-QFP (14×14 mm) package supports compact PCB layouts while providing full access to the processor’s I/O and control features.
• Integrated system support: Built-in DRAM controller and memory-mapped I/O support simplify system-level design and reduce external component count.
