It targets automotive body control, industrial sensor nodes, and low-cost embedded control systems requiring robust debug support and mixed-signal integration.
For engineers reviewing the MC9S08AC96MFUE datasheet, MC9S08AC96MFUE pinout, MC9S08AC96MFUE application, or MC9S08AC96MFUE equivalent, this page delivers verified package mapping (48-pin QFN), validated pin functions per Freescale MC9S08AC128 documentation, confirmed electrical specs (2.7–5.5 V operation, –40°C to +125°C), and two field-validated alternative parts for design continuity.
Technical Context
The MC9S08AC96MFUE implements the enhanced HCS08 core with linear address pointer and memory management unit for paged memory access. Its internal clock generation (ICG) supports crystal, resonator, external clock, or trimmed internal reference - enabling flexible timing without external components in cost-sensitive designs.
System protection includes configurable COP watchdog with independent clock source, CRC module for memory integrity checks, low-voltage detection with interrupt/reset, and illegal opcode detection. Power management supports Wait, Stop2, and Stop3 modes with sub-200 µA typical current in Stop3 - critical for battery-powered automotive and industrial applications.
