MC96F8208SU

The MC96F8208SU is an 8-bit CMOS microcontroller based on a high-speed 8051 CPU core, integrating 8 Kbytes of Flash program memory and 512 bytes of SRAM (256 bytes iRAM + 256 bytes xRAM). It delivers a compact, integrated control platform for embedded control applications and small home appliance designs.

With an internal 16 MHz RC oscillator, a 12-bit A/D converter, multiple timer/PWM peripherals and common serial interfaces (I2C, SPI, UART), the device is positioned to simplify system design while supporting a wide supply voltage range (1.8–5.5 V) and industrial temperature operation (−40 to 85 °C).

• Memory 8 Kbytes of on-chip Flash program memory and 512 bytes of SRAM split as 256 bytes iRAM and 256 bytes xRAM for data and stack usage.
• Analog 12-bit A/D converter with 10 inputs and up to 50 ksps sampling throughput for precise analog measurement and sensor interfacing.
• Timers & PWM Multiple timer/counter channels with 8/16-bit resolution, 16-bit PPG and 8-bit PWM outputs, plus a dedicated buzzer-driving port for audio signaling.
• Serial Interfaces Integrated communications including I2C, SPI and one UART channel to support a range of peripheral and sensor buses.
• System Reliability & Reset Built-in Power-On Reset (POR), Low Voltage Reset/Detect (LVR/LVI) and Watchdog Timer (WDT) to improve system robustness.
• Clocking Internal 16 MHz RC oscillator (±1.5% at 0–50 °C) with support for external oscillator sources.
• Power & Low-Power Modes Wide supply voltage range (1.8–5.5 V) and power saving modes to reduce consumption in standby and active states.
• I/O & Package Up to 18 programmable I/O lines in a compact 20-pin QFN package (20-QFN, 4x4-0.5 mm), suitable for surface-mount applications.
• Environmental Range Industrial operating temperature range from −40 to 85 °C for reliable operation across common application environments.

Typical Applications

• Small Home Appliances Control and user-interface tasks in appliances where compact integration, ADC inputs and PWM/timer control are required.
• Embedded Control Applications General-purpose embedded control roles that benefit from an 8051 core, on-chip Flash and multiple peripheral interfaces.
• Sensor Measurement and Analog Interfacing Multi-channel 12-bit ADC enables precise sensor data acquisition and analog signal monitoring in compact systems.
• Battery-Powered and Portable Devices Wide supply range (1.8–5.5 V) and power-saving modes support designs that require flexible power sources and energy-efficient operation.

Unique Advantages

• Highly integrated MCU: 8 Kbytes Flash, 512 bytes SRAM and a 12-bit ADC on a single chip reduce external component count and simplify BOM.
• Flexible clocking: Internal 16 MHz RC oscillator and support for external oscillators provide design flexibility for timing and cost trade-offs.
• Broad supply compatibility: 1.8–5.5 V operation enables direct use across a range of power domains and battery types.
• Industrial temperature range: −40 to 85 °C operation supports deployment in varied environmental conditions.
• Compact surface-mount package: 20-QFN (4x4-0.5 mm) provides a small footprint for space-constrained PCBs.
• Built-in system safety features: POR, LVR/LVI and WDT help maintain reliable operation and reduce external supervisory circuitry.
