MC97F2664UB

The MC97F2664 is an 8-bit CMOS microcontroller based on the 8051 core, offering 64 Kbytes of on-chip Flash and 4.25 Kbytes of RAM for embedded control applications. Its integrated peripherals—including timers, PWM, a 12-bit ADC and multiple serial interfaces—provide a flexible platform for compact, cost-effective system designs.

Designed for mixed-signal control, the device supports internal and external oscillators, a wide supply range of 1.8–5.5 V, and power-saving modes to help optimize energy use across applications operating from –40 to 85 °C.

Key Features

• Core and Performance 8051-based 8-bit core running at up to 16 MHz for predictable, legacy-friendly MCU performance.
• Memory 64 Kbytes of on-chip Flash program memory and 4.25 Kbytes of RAM to support embedded firmware and data buffers.
• Analog and Data Conversion 12-bit ADC with 15 channels and up to 50 ksps for precision sensor interfacing and analog monitoring.
• Timers and PWM Multiple timers (8-bit and 16-bit) and PWM channels (8-bit and 16-bit) for timing, control and power-management tasks.
• Connectivity Serial interfaces including SPI, UART and USI to connect displays, sensors and external peripherals.
• System Peripherals Integrated buzzer driver, LDO, power-on reset (POR), watchdog timer (WDT) and wake timer (WT) for robust system control and reliability.
• I/O and Packaging Up to 61 general-purpose I/O pins in a compact 64‑QFN (8 × 8 × 0.4 mm) surface-mount package, simplifying board layout while maximizing signal access.
• Power and Environmental Operates across 1.8–5.5 V and specified for an operating temperature range of –40 to 85 °C, with both internal and external oscillator options and power-saving modes available.

Typical Applications

• Embedded Control — General-purpose control tasks where integrated timers, PWM and I/O count support device control and sequencing.
