MC96F8216PU2N

The MC96F8216PU2N is an 8-bit CMOS microcontroller based on an M8051 core with on-chip Flash and SRAM designed for compact embedded applications. It integrates timing, analog and serial peripherals with a wide operating voltage range and low current consumption, making it suitable for battery-operated devices and general-purpose control systems.

Designed for engineers requiring a balanced combination of compute, analog I/O and peripheral integration, the device supports internal and external oscillators and operates across an extended temperature range for robust deployment.

Key Features

• Core  M8051 8-bit core (8051 compatible) with 2 clocks per cycle and a typical internal high-frequency RC oscillator rated at 16 MHz ±1.0% (user trim available).
• Memory  16 KB on-chip Flash (ISP) for program storage and 768 bytes of RAM (256 bytes IRAM + 512 bytes XRAM as specified in the device documentation).
• Power and Voltage  Wide operating voltage range from 1.8 to 5.5 V and an internal voltage dropout converter for the core; optimized for low current consumption in battery-powered applications.
• Timers and Watchdog  Multiple timers including Basic Interval Timer (8-bit), Watchdog Timer (8-bit), 8-bit T0 and two 16-bit timers (T1/T2) plus power-down modes (STOP, IDLE) for low-power operation.
• Analog  12-bit A/D converter with 11 input channels (device variant), including power-down wake-up function for energy-efficient sensor interfacing.
• Pulse and PWM  Programmable pulse generation via T1/T2 and 8-bit PWM via T0; additional buzzer support (8-bit) for simple audio signaling.
• Connectivity  Integrated serial interfaces: I2C (1), SPI (1) and UART (2) channels for peripheral and module communication.
• System Reliability  Power-on Reset (POR), Low Voltage Reset (LVR) and Low Voltage Indicator (LVI) with multiple detect levels, plus a 16-bit CRC/checksum generator (auto and user modes) for data integrity.
• I/O and Package  22 general-purpose I/O pins in a compact 24‑QFN (4 × 4 × 0.5 mm) surface-mount package optimized for space-constrained boards.
• Environmental Range  Rated for operation from –40 to +105 °C for deployment across extended-temperature applications.

Typical Applications

• Battery-powered instruments  Low-voltage operation and low current consumption suit handheld or portable measurement and control devices.
• Sensor hubs and data acquisition  12-bit ADC with multiple channels and wake-up on ADC power-down enable efficient sensor interfacing and event-driven sampling.
• Consumer and appliance control  Integrated timers, PWM and multiple UART/I2C/SPI interfaces support user interface control, actuator drive and peripheral connectivity.
• Industrial control nodes  Extended temperature range, POR/LVR/LVI and CRC support make the device appropriate for compact control and monitoring modules.

Unique Advantages

• Highly integrated peripheral set: Combines ADC, multiple timers, PWM, CRC, watchdog and serial interfaces to reduce BOM and simplify board design.
• Flexible power envelope: Wide 1.8–5.5 V supply range and internal voltage converter for the core allow operation from common battery chemistries and varied system rails.
• Compact package: 24‑QFN 4 × 4 mm package delivers a small footprint for space-constrained designs without sacrificing I/O count (22 pins).
• Robust operating range: –40 to +105 °C rating enables deployment in thermally demanding environments.
• Memory and code compatibility: 16 KB Flash with ISP and M8051 compatibility supports established 8-bit firmware ecosystems and in-system programming workflows.
