MC97F2664ASUB

The MC97F2664ASUB is an advanced CMOS 8-bit microcontroller based on a high-speed M8051 core. It combines 64 Kbytes of Flash, 4.25 Kbytes of SRAM (256 bytes IRAM + 4 Kbytes XRAM) and a broad set of on-chip peripherals to address embedded control applications in home appliances and industrial control.

Designed for flexible integration, the device supports a wide supply range (2.2–5.5 V), an internal 16 MHz RC oscillator and multiple serial interfaces, enabling compact, cost-effective designs that require ADC, timers, PWM and robust system management features such as POR, LDO and WDT.

Key Features

• Core  M8051 8-bit CISC CPU with 2 clocks per cycle and support for an internal 16 MHz RC oscillator (±2.0%, TA = 0 ~ +50°C) and external clock sources.
• Memory  64 Kbytes of on-chip Flash with self read/write and ISP/On-Chip debug capability, plus 4352 bytes of SRAM (256 bytes IRAM + 4096 bytes XRAM). Flash endurance and retention are documented in the datasheet.
• Analog  12-bit A/D converter with 15 input channels and up to 50 ksps sampling for sensor interfacing and precision measurement.
• Timers & PWM  Multiple timer resources including four 8-bit timers and six 16-bit timers, plus 8-bit PWM channels and dedicated buzzer output for pulse generation and motor/actuator control.
• Serial Interfaces  Rich connectivity with UART (up to three 8-bit channels), SPI (two 8-bit channels) and two USI blocks supporting UART/SPI/I2C combinations.
• System Reliability  Integrated Power-On Reset (POR), low-voltage detection (LVR/LVI), watchdog timer (WDT) and 16-bit CRC/checksum generator for system monitoring and data integrity.
• Power & Low-Power  On-chip LDO and multiple power-saving modes to optimize energy consumption across a wide supply window (2.2–5.5 V).
• I/O & Package  Up to 61 programmable I/O lines in a compact 64-QFN package (8 × 8 × 0.75–0.4 mm), suitable for high-density PCB designs.
• Operating Range  Industrial-temperature operation from −40 °C to +85 °C for deployment in varied environmental conditions.

Typical Applications

• Home Appliances  Embedded control for appliances such as washing machines, HVAC controllers and smart kitchen devices where ADC, timers and PWM manage sensors, motors and user interfaces.
• Industrial Control  Process and machine control applications that require multiple timers, robust I/O and reliable reset/watchdog features for stable operation.
• Sensor Hubs & Measurement  Multi-channel 12-bit ADC and CRC engine enable sensor aggregation, signal conversion and integrity checks in compact sensor nodes.
• Human Interface & Indicator Control  Multiple UART/SPI channels, buzzer output and abundant GPIO support display, keypad and alert functions in consumer and industrial products.

Unique Advantages

• Highly integrated feature set: Combines Flash, SRAM, ADC, timers, PWM, UART/SPI/USI and system monitors on a single chip to reduce BOM and simplify board design.
• Flexible power envelope: Wide supply range (2.2–5.5 V) plus on-chip LDO and power-saving modes allow deployment across battery-powered and line-powered designs.
• Robust system management: Built-in POR, LVR/LVI and WDT protect against power and runtime faults, improving reliability in long-running applications.
• Compact footprint with extensive I/O: 61 programmable I/O lines in a 64-QFN package support high-density layouts without sacrificing peripheral access.
• Proven memory capabilities: 64 Kbytes of Flash with documented endurance and minimum retention, plus separate IRAM/XRAM for deterministic RAM usage and stack/data separation.
