Product details
Overview
MC68SEC000AE10 from Motorola is a static 32-bit embedded microprocessor designed for ultra-low-power applications, featuring 24-bit address bus, 16-bit data bus (8/16-bit selectable), 10 MHz operation at 3.3V or 5.0V, 0.5 µA static standby current, and pin-for-pin compatibility with MC68EC000. It serves as the core controller in battery-powered handheld devices such as PDAs and portable test equipment.
For engineers reviewing the MC68SEC000AE10 datasheet, MC68SEC000AE10 pinout, MC68SEC000AE10 application, or MC68SEC000AE10 equivalent, key selection criteria include static low-power operation, M68000 family object-code compatibility, 64-pin QFP/TQFP packaging, interrupt-level support (IPL0–IPL2), and asynchronous bus control signals (AS, DTACK, UDS/LDS).
Technical Context
The MC68SEC000AE10 implements a fully static HCMOS version of the M68000 architecture with eight 32-bit data registers, eight 32-bit address registers, 16-Mbyte linear addressing, and 14 addressing modes. Its execution unit supports 56 instruction types across five data types and enables memory-mapped I/O.
Hardware compatibility with MC68EC000 includes identical pinout in 64-lead QFP/TQFP packages and identical asynchronous bus protocol using AS, R/W, UDS/LDS, and DTACK. The processor supports seven interrupt levels with autovectoring via AVEC and uses FC0–FC2 to indicate supervisor/user mode and address space during valid AS cycles.

FAQ
What voltage levels does the MC68SEC000AE10 support?
The MC68SEC000AE10 operates at either 3.3V or 5.0V supply voltage, allowing direct integration into both legacy 5V systems and modern low-voltage designs. This dual-voltage capability ensures backward compatibility with MC68EC000 hardware while enabling reduced power consumption in 3.3V implementations. The MC68SEC000AE10 maintains full functionality and timing specifications across both voltage grades without external level-shifting circuitry.
Is the MC68SEC000AE10 pin-compatible with the MC68EC000?
Yes, the MC68SEC000AE10 is pin-for-pin compatible with the MC68EC000 in the 64-lead plastic QFP package. All signal names, pin positions, and electrical characteristics match exactly, permitting direct PCB-level replacement without layout modification. The MC68SEC000AE10 retains identical asynchronous bus control signaling (AS, DTACK, UDS/LDS) and interrupt interface (IPL0–IPL2, AVEC), ensuring hardware interoperability.
What is the standby current specification for the MC68SEC000AE10?
The MC68SEC000AE10 draws only 0.5 µA typical current in static standby mode at 3.3V, enabling multi-year battery operation in always-on portable devices. This ultra-low quiescent current is achieved through its fully static HCMOS design, which permits complete clock stopping while preserving register and memory contents. The MC68SEC000AE10 achieves this without external power switches or auxiliary circuitry.
Does the MC68SEC000AE10 support 8-bit data transfers?
Yes, the MC68SEC000AE10 supports configurable 8-bit or 16-bit data bus operation via the MODE pin. When MODE is asserted, the processor uses D7–D0 for data transfer and asserts only LDS (not UDS), enabling seamless interface to 8-bit peripherals and memory. This flexibility allows the MC68SEC000AE10 to connect directly to low-cost 8-bit SRAM, EPROM, or I/O expanders without bus-width translation logic.
What development tools are compatible with the MC68SEC000AE10?
All third-party development tools supporting the MC68EC000 - including assemblers, C compilers, debuggers, and emulators - are fully compatible with the MC68SEC000AE10 due to object-code and hardware equivalence. The MC68SEC000AE10 leverages the same M68000 Programmer's Reference Manual and User's Manual, eliminating toolchain requalification effort. Existing firmware built for MC68EC000 runs unchanged on the MC68SEC000AE10.
