MC97FG316LBN

The MC97FG316LBN is an advanced CMOS 8-bit microcontroller based on the M8051 core, designed for embedded control applications requiring integrated analog, timing and communications peripherals. It combines a 16 Kbyte on-chip Flash program memory with a comprehensive peripheral set — including multi-channel PWM, a 12-bit ADC with up to 15 inputs, multiple USART/SPI/I2C interfaces and power-saving modes — to simplify system design and reduce external component count.

Housed in a 32-pin LQFP (7×7‑0.8 mm) surface-mount package and supporting a wide supply range (1.8–5.5 V) and extended operating temperatures, the device is suited to a variety of sensor, motor-control and consumer embedded systems where integration, flexibility and energy efficiency are important.

Key Features

• Core & Performance — 8-bit M8051 CISC core running up to 16 MHz main clock with a minimum instruction execution time of 125 ns at 16 MHz.
• On-chip Memory — 16 Kbytes of on-chip Flash program memory, 512 bytes of EEPROM, and 1 Kbyte of RAM (256 bytes IRAM and 768 bytes XRAM) for code and data storage.
• Analog Subsystem — 12-bit A/D converter with up to 15 input channels (on 32‑pin package) plus a single on-chip analog comparator and a dedicated buzzer output.
• Timers & PWM — Multiple timers including 4×8-bit and 1×16-bit timers (T0–T4), a Basic Interval Timer and an 8-bit Watchdog Timer; PWM capability includes three high-frequency 10-bit PWMs (for 3‑phase control) and additional 8/16-bit PWM channels.
• Communications — Rich serial connectivity with 2×USART, 1×SPI and 1×I2C channel to support peripherals, sensors and user interfaces.
• Power & Clocking — Wide supply voltage range of 1.8–5.5 V, internal and external oscillator options (internal RC at 16 MHz and 1 MHz sub-clock), and power-saving STOP and IDLE modes to lower energy consumption.
• System Reliability & Reset — Watchdog Timer, Power-on Reset (reset release at 1.4 V) and selectable Low Voltage Reset detection levels for robust start-up and fault recovery.
• Package & I/O — 32‑pin LQFP (7×7‑0.8 mm) surface-mount package providing up to 30 general-purpose I/O pins for flexible system integration; operating temperature options documented down to −40 °C.

Typical Applications

• Motor and Drive Control — 3‑phase 10‑bit PWM and multiple timer channels enable compact motor-control designs such as fans, pumps and small BLDC drives.
• Sensor Hubs and Data Acquisition — 12‑bit ADC with up to 15 channels provides multi-sensor analog input capability for environmental, industrial or consumer sensing nodes.
• Home Appliances and Consumer Electronics — Integrated timers, PWM, buzzer and serial interfaces make the device suitable for user-interface control and appliance motor/timing functions.
• Battery-Powered and Portable Devices — Low-voltage operation (1.8–5.5 V) and STOP/IDLE power-saving modes support energy-efficient portable applications.

Unique Advantages

• Highly integrated peripheral set: On-chip ADC, comparator, multiple PWMs, timers and serial interfaces reduce external components and BOM complexity.
• Flexible power and clock options: Wide supply range and both internal/external oscillator support simplify design choices across low-voltage and mixed-frequency systems.
• Multiple communication channels: Dual USART plus SPI and I2C enable simultaneous links to displays, sensors and submodules without additional bridging logic.
• Precision analog inputs: 12‑bit A/D with up to 15 channels supports high-resolution sensor interfacing and multi-channel data acquisition.
• Compact, production-ready package: 32‑pin LQFP (7×7‑0.8 mm) surface-mount package offers up to 30 GPIOs for dense board layouts and flexible pin assignment.
• Robust reset and safety features: Built-in Watchdog Timer, Power-on Reset behavior and selectable low-voltage reset levels help improve system reliability.
