MC68SEC000AA20B1

The MC68SEC000AA20B1 is a static EC000-series embedded microprocessor implementing a single 32-bit core. It delivers 20 MHz operation in a 64-pin QFP (14 × 14 mm) surface-mount package for compact, low-power embedded designs.

Engineered for low-power, portable and battery-operated applications, the device supports 3.3 V or 5.0 V systems and includes a low-power standby mode. Typical use cases include handheld consumer products, portable measuring equipment and other space-constrained, power-sensitive systems.

Key Features

• Core and Architecture  EC000 core with a single 32‑bit processor; internal 32‑bit architecture with eight 32‑bit address registers and eight 32‑bit data registers as documented for the MC68SEC000 family.
• Performance  20 MHz maximum operating speed as specified for this part.
• Power Management  Static HCMOS design enabling clock stop; typical current consumption cited as 0.5 µA in static standby and 15.0 mA in normal 3.3 V operation. Operates in either 3.3 V or 5.0 V systems.
• Memory and Addressing  16‑Mbyte linear addressing range and memory‑mapped I/O support, plus multiple addressing modes and instruction types documented for the EC000 architecture.
• Interfaces  Includes DRAM controller support and one 10 Mbps Ethernet interface as listed in product specifications.
• Package and Mounting  64‑lead plastic Quad Flat Pack (64‑QFP, 14 × 14 mm) for surface‑mount assembly, enabling compact board layouts.
• Operating Range and Compliance  Commercial operating temperature range of 0 °C to 70 °C; RoHS compliant.
• Software Compatibility  Object‑code compatibility with the M68000 family and pin‑for‑pin replacement compatibility with MC68EC000 in the QFP package (as documented for the MC68SEC000 family).

Typical Applications

• Handheld Consumer Devices  Low standby current and compact QFP package make the part suitable for battery‑operated electronic games and personal digital assistants.
• Portable Measurement Equipment  32‑bit architecture and DRAM controller support enable responsive control and data handling in portable instruments.
• Battery‑Operated Products  Static design and low power modes reduce quiescent current for extended battery life in field devices.
• Embedded Control Systems  Memory‑mapped I/O and a broad set of addressing modes help implement control and interface functions in compact embedded systems.

Unique Advantages

• Low Standby Current:  Typical 0.5 µA in static standby for minimized battery drain during idle periods.
• Dual Supply Operation:  Supports 3.3 V or 5.0 V systems to accommodate mixed-voltage designs.
• Static Architecture:  Clock can be stopped to reduce dynamic power consumption, simplifying power management strategies.
• Compact Surface‑Mount Package:  64‑QFP (14 × 14 mm) enables small PCB footprint for space-constrained applications.
• Software and Hardware Compatibility:  Object‑code compatibility with the M68000 family and pin‑for‑pin replacement compatibility within the EC000/SEC000 family reduce migration effort and leverage existing toolchains.
• Integrated System Interfaces:  On‑chip DRAM controller and a 10 Mbps Ethernet interface provide system integration options for embedded designs.
