MC96F8216AU

The MC96F8216AU is a CMOS 8-bit microcontroller based on a high-speed 8051-compatible CPU, offering 16 Kbytes of on-chip Flash and a rich set of integrated peripherals for embedded control applications. It is targeted at compact, cost-sensitive designs such as small home appliances and other embedded systems that require mixed-signal capability, timing control, and low-power operation.

With an internal 16 MHz oscillator, a 12-bit A/D converter and multiple serial interfaces, the MC96F8216AU delivers a balanced combination of performance, integration and flexibility for designers working within a 2.2–5.5 V supply range and –40 °C to +85 °C operating conditions.

Key Features

• Core  High-speed 8-bit M8051-compatible CISC CPU (2 clocks per cycle) with a 16 MHz operating clock option.
• Memory  16 Kbytes of on-chip Flash program memory and 768 bytes of SRAM (256 bytes iRAM + 512 bytes xRAM) for code and data storage.
• Analog  12-bit A/D converter with multiple inputs (MC96F8216AU provides 11 ADC inputs) for precision sensor and analog signal acquisition.
• Timers & PWM  Integrated timers and counters including 8-bit and 16-bit timers, watchdog timer (WDT) and a watch timer, plus 8-/16-bit PWM outputs for motor, buzzer or power control tasks.
• Serial Interfaces  Hardware support for UART (1), SPI (1) and I2C (1) for flexible peripheral and sensor connectivity.
• System Reliability & Power  On-chip power-on reset (POR), low-voltage detection/reset and support for power-down modes to reduce power consumption in standby.
• Clock Options  Internal 16 MHz RC oscillator (±1.5% at TA = 0 to +50 °C) and support for external clock sources; separate watchdog RC oscillator (~5 kHz).
• IO & Package  22 programmable I/O lines in a compact 24‑QFN (4 × 4 × 0.5 mm) surface-mount package; Pb-free package option.
• Operating Range  Wide supply voltage range of 2.2 V to 5.5 V and industrial operating temperature range of −40 °C to +85 °C.

Typical Applications

• Small Home Appliances  Control and sensing tasks in compact appliances—leveraging the integrated A/D converter, timers and PWM outputs for user controls, motor and actuator interfaces.
• Embedded Control Systems  General-purpose embedded applications that require a mix of digital I/O, timers and serial communications using the 8051-compatible core and on-chip peripherals.
• Human‑Machine Interfaces  LED drive, buzzer control and GPIO-driven UI elements using the dedicated buzzer and high-current LED driver port.

Unique Advantages

• Highly integrated mixed-signal feature set: Combines 16 KB Flash, SRAM, 12-bit ADC and multiple timers/PWM channels on a single chip to reduce BOM and PCB area.
• Flexible connectivity: Built-in UART, SPI and I2C interfaces simplify sensor and peripheral integration without external bridge components.
• Wide supply and temperature range: 2.2–5.5 V operation and −40 °C to +85 °C rating support a broad set of embedded use cases.
• Compact surface-mount package: 24‑QFN (4 × 4 mm) enables space-constrained designs while providing up to 22 programmable I/O lines.
• On-chip power and safety features: Power-on reset and low-voltage detection together with watchdog and power-down modes enhance system stability and robustness.
