MC94F1102AMB

The MC94F1102A is an 8-bit CMOS microcontroller based on a high-performance CM8051-S CPU core. It combines on-chip Flash, SRAM, mixed-signal peripherals and multiple system-level features to address compact embedded control applications.

Designed for battery management and small appliance control, the device targets applications that require integrated analog sensing, timing/PWM and low-power operation across a wide supply and temperature range.

Key Features

• Core  High-performance CM8051-S 8-bit CPU architecture with a specified operating rate of 16 MHz.
• Memory  2 Kbytes of on-chip Flash program memory with code area protection and 256 bytes of SRAM data memory.
• Analog  12-bit A/D converter with 6 channels for precise sensor and battery voltage monitoring.
• Timers and PWM  Integrated 16-bit timer/counter with PWM capability for motor control and duty-cycle generation.
• Clocking  Internal oscillator options including an internal RC oscillator; datasheet notes a 32 MHz internal RC oscillator (±1.5% @ 25°C).
• System Reliability  On-chip Power-On Reset (POR), Low-Voltage Interrupt/Reset (LVI/LVR) and a Watchdog Timer (WDT) with WDT oscillator for robust operation.
• Power Management  Multiple power-saving modes to reduce consumption in battery-powered designs; supports a wide supply range of 2.2–5.5 V.
• I/O and Package  6 programmable I/O lines in an 8-SOP (150 mil) surface-mount package; the MC94F1x02A family also offers multiple package options across the series.
• Operating Range  Specified for operation from −40 °C to 85 °C for applications demanding extended temperature capability.

Typical Applications

• Battery charge & discharge control  On-chip 12-bit ADC, LVI/LVR and POR support accurate voltage monitoring and safe battery management logic.
• Small home appliances  Integrated timers, PWM and MCU core enable compact motor and user-interface control in appliance designs.
• Embedded control and sensing  Combined ADC, timer/PWM and low-power modes make the device suitable for general embedded control tasks with sensor inputs and duty-cycle outputs.

Unique Advantages

• Highly integrated mixed-signal platform: 2 KB Flash, 256 B SRAM, 12-bit ADC and 16-bit timer/CNT/PWM reduce BOM and board area.
• Wide supply flexibility: Operates from 2.2 to 5.5 V, enabling direct use in a variety of battery and single-supply systems.
• Robust system features: On-chip POR, LVI/LVR and WDT with its own oscillator provide watchdog and brown-out protection for dependable field operation.
• Compact surface-mount package: 8-SOP (150 mil) package provides a small footprint for space-constrained designs.
• Extended temperature capability: −40 °C to 85 °C operation supports use in industrial and outdoor environments.
