Product details
Overview
MC68SEC000AA10 from Motorola is a static 32-bit embedded microprocessor designed for ultra-low-power portable systems. It delivers 10 MHz operation at 3.3 V or 5.0 V, consumes only 0.5 µA in static standby mode, supports 24-bit addressing (16 MB), and features pin-for-pin compatibility with the MC68EC000 - enabling direct replacement in battery-powered PDAs and handheld test equipment.
For engineers reviewing the MC68SEC000AA10 datasheet, MC68SEC000AA10 pinout, MC68SEC000AA10 application, or MC68SEC000AA10 equivalent, this page provides verified electrical specifications, package mapping to 64-lead QFP/TQFP, static low-power architecture details, and confirmed M68000 Family object-code compatibility - all essential for legacy 68k system upgrades and power-constrained embedded designs.
Technical Context
The MC68SEC000AA10 implements a fully static HCMOS version of the M68000 architecture with eight 32-bit data registers, eight 32-bit address registers, and 14 addressing modes. Its bus controller supports asynchronous transfers via AS, R/W, UDS/LDS, and DTACK, with 24-bit address and statically selectable 8-/16-bit data bus width.
Interrupt handling includes seven priority levels (IPL0–IPL2 + nonmaskable Level 7) with automatic vectoring via AVEC input. Processor status outputs FC2–FC0 indicate supervisor/user mode and address space during active AS cycles - critical for memory-mapped I/O and real-time OS integration.

FAQ
What voltage levels does the MC68SEC000AA10 support?
The MC68SEC000AA10 operates at either 3.3 V or 5.0 V, allowing direct integration into both modern low-voltage and legacy 5 V embedded systems. This dual-voltage capability ensures backward compatibility with existing MC68EC000 designs while supporting newer power-efficient architectures - a key factor in its use for PDA and portable instrumentation upgrades.
Is the MC68SEC000AA10 pin-compatible with the MC68EC000?
Yes, the MC68SEC000AA10 is pin-for-pin compatible with the MC68EC000 in the 64-lead plastic QFP package. This includes identical signal assignments for address, data, control, and interrupt pins - enabling drop-in replacement on existing PCBs without layout modification or signal rerouting, which significantly reduces redesign effort and qualification time for legacy system updates.
Does the MC68SEC000AA10 support true static operation?
Yes, the MC68SEC000AA10 features a fully static HCMOS core that retains full internal state when the clock is stopped. In static standby mode at 3.3 V, it draws only 0.5 µA typical current - enabling indefinite power-down periods with instantaneous wake-up, a critical requirement for battery-powered applications like handheld medical devices and remote data loggers.
What is the maximum clock frequency of the MC68SEC000AA10?
The MC68SEC000AA10 is rated for a maximum clock frequency of 10 MHz. This speed is specified under both 3.3 V and 5.0 V supply conditions and defines the upper bound for instruction execution timing, bus cycle duration, and real-time response latency - making it suitable for deterministic control tasks in portable instrumentation and industrial HMIs.
How does the MC68SEC000AA10 handle interrupt prioritization?
The MC68SEC000AA10 implements seven hardware interrupt priority levels using IPL0–IPL2 inputs, with Level 7 being nonmaskable and highest priority. Combined with the AVEC input, it supports automatic vectoring to dedicated interrupt service routines - ensuring predictable, low-latency response to time-critical events such as sensor triggers or communication timeouts in embedded control systems.
