MC97FG316UBN

The MC97FG316UBN is an advanced CMOS 8-bit microcontroller based on the M8051 core, offering 16 Kbytes of on‑chip Flash memory and a rich peripheral set for embedded control applications. Its combination of integrated analog, timers, communication interfaces and power-management features makes it suitable for compact, energy-conscious control designs.

Designed to run up to a 16 MHz main clock, the device supports both internal and external oscillators, a wide supply range (1.8–5.5 V) and industrial operating temperatures (‑40 to +85 °C), enabling deployment across a variety of temperature and power environments.

Key Features

• Core & Performance M8051 8‑bit CISC core with up to 16 MHz main clock (minimum instruction execution time 125 ns at 16 MHz) for deterministic control tasks.
• Flash, EEPROM & RAM 16 Kbytes on‑chip Flash program memory, 512 bytes data EEPROM and 1 Kbyte RAM (256 bytes iRAM + 768 bytes xRAM) for local code and data storage.
• Analog & Data Conversion 12‑bit A/D converter with multiple channels (up to 15 inputs on 32‑pin package) plus an on‑chip analog comparator for precision sensor interfacing.
• Timers, PWM & Buzzer Multiple timers including 8‑bit and 16‑bit channels, Watchdog Timer (WDT), Basic Interval Timer and dedicated PWM resources (10‑bit PWM channels) along with an integrated buzzer output for user feedback and motor/actuator control tasks.
• Serial Interfaces Rich connectivity with USART ×2, SPI ×1 and I²C ×1 for peripheral communication, sensor networks and host connectivity.
• Power & Clock Options Internal RC oscillators (HSI 16 MHz, LSI 1 MHz) and external crystal support, plus low‑power modes (STOP, IDLE) and selectable low‑voltage reset levels to help manage energy consumption and safe start‑up.
• System Reliability Watch Timer intervals and a hardware WDT help maintain robust operation; multiple low‑voltage reset thresholds and power‑on reset features assist in controlled power sequencing.
• Package & I/O 32‑lead QFN package with 30 GPIO pins (device variant MC97FG316U), surface‑mount friendly and suitable for compact board layouts; operating temperature up to +85 °C.

Typical Applications

• Embedded control systems — On‑board Flash, EEPROM and multiple timers make the MC97FG316UBN well suited for general embedded control tasks and appliance controllers.
• Sensor interfacing & data acquisition — 12‑bit ADC channels and serial interfaces (I²C, SPI, USART) provide the analog and digital connectivity needed for sensor front‑ends and measurement nodes.
• User interface & feedback — Integrated PWM channels and a buzzer output enable responsive UI elements such as tone alerts, LED dimming and simple motor drives.
• Battery‑aware and power‑sensitive devices — Wide supply range (1.8–5.5 V) and STOP/IDLE power modes support portable and energy‑conscious applications.

Unique Advantages

• Highly integrated memory mix — 16 KB Flash, 512 B EEPROM and 1 KB RAM reduce external memory needs and simplify firmware/data storage strategies.
• Versatile analog and timing resources — 12‑bit ADC, analog comparator, multiple timers and PWM channels provide flexible signal processing and control capabilities without additional ICs.
• Flexible clocking and power envelope — Internal RC and external crystal options with operation from 1.8 to 5.5 V enable designs across a wide range of power and timing requirements.
• Compact, surface‑mount package — 32‑QFN package delivers a small footprint with up to 30 GPIOs, ideal for space‑constrained PCBs.
• Industrial operating temperature — Device operation from ‑40 to +85 °C supports deployment in demanding thermal environments.
• Multiple serial peripherals — Dual USARTs plus SPI and I²C allow simultaneous communication channels for sensors, displays and host interfaces.
