The MC94F1102A is an 8-bit CMOS microcontroller based on the high-performance CM8051-S CPU core. It combines 2 Kbytes of on-chip Flash, 256 bytes of SRAM, integrated analog and timing peripherals, and power-management features aimed at low-power embedded control applications.

Designed for compact control tasks such as battery charge/discharge management and small home appliances, the MC94F1102A offers a balance of integration and flexibility across a 2.2–5.5 V operating range and extended temperature support.

Key Features

• Core CM8051-S 8-bit CPU delivering deterministic control for embedded applications; rated operation up to 16 MHz system speed.
• Memory 2 Kbytes of on-chip Flash program memory with code-area protection and 256 bytes of SRAM data memory for compact firmware and scratch storage.
• Timers & PWM Integrated 16-bit timer/counter with PWM capability for motor or power control and precise timing tasks.
• Analog & ADC 12-bit A/D converter (6 channels) for accurate sensor interfacing and measurement in battery- and sensor-driven systems.
• System Reliability On-chip Power-On Reset (POR) with Low-Voltage Indicator (LVI) and Low-Voltage Reset (LVR), plus a Watch Dog Timer (WDT) with internal WDT oscillator to improve system robustness.
• Clocking & Power Internal RC oscillator (documented 32 MHz RC option) and power-saving modes enable reduced external component count and flexible power management across 2.2–5.5 V.
• I/O & Package Configurable I/O (6 available I/O lines for the 8-SOP package) in a compact 8-SOP (150 mil) surface-mount package.
• Operating Range Designed for deployment across an extended temperature range from −40 to 105 °C.

Typical Applications

• Battery charge & discharge control — On-chip ADC, watchdog, and power-management features support reliable monitoring and control of battery systems.
• Small home appliances — Integrated timers, PWM, and analog inputs enable motor control, user-interface management, and sensor reading in compact appliance designs.
• Low-power embedded control — Internal oscillator and power-saving modes make the device well-suited for energy-conscious sensor hubs and embedded controllers.

Unique Advantages

• Highly integrated control — Flash, SRAM, ADC, timers, and watchdog are all on-chip, reducing BOM and board space for compact designs.
• Flexible power operation — Wide VDD range (2.2–5.5 V) and LVI/LVR/POR support enable reliable operation across battery- and adapter-powered systems.
• Robust reset and supervision — On-chip POR and watchdog with internal WDT oscillator provide hardware-level protection against brownouts and software lockups.
• Accurate analog measurement — 12-bit ADC across multiple channels simplifies precise sensor interfacing without external converters.
• Compact SMD footprint — 8-SOP (150 mil) surface-mount package suits space-constrained PCBs while providing necessary I/O for control tasks.
