MC97F2664ASL14

The MC97F2664ASL14 is an advanced CMOS 8-bit microcontroller based on a high-speed 8051 (M8051) CPU. It integrates 64 Kbytes of on-chip Flash, multiple timers, a 12-bit ADC, watchdog and power-on reset functions, and supports both internal and external oscillator sources for flexible clocking.

Designed for embedded control applications such as home appliances and industrial control, the device delivers a compact, integrated solution that reduces external components while offering a wide operating voltage range and extended temperature support.

Key Features

• Core & Clocking  High-speed 8-bit M8051 CISC core (2 clocks per cycle) with an internal 16 MHz RC oscillator (±2.0% at TA = 0 ~ +50°C) and support for external crystal oscillators. A watchdog-timer RC oscillator (5 kHz) is included for robust operation.
• Memory  64 Kbytes of on-chip Flash with self read/write capability and In-System Programming (ISP). RAM includes 256 bytes of IRAM and 4,096 bytes of XRAM (total 4.25 Kbytes).
• Program Flash Reliability  Flash endurance and retention are specified: 10,000 program/erase cycles for sectors 0–1019, 100,000 cycles for sectors 1020–1023, and minimum 10 years data retention.
• Power & Reset  On-chip Power-On Reset (POR), Low Voltage Reset/Detect (LVR/LVI) and an integrated LDO. Operates across a wide supply range of 2.2 V to 5.5 V and supports power-down modes to reduce power consumption.
• Timers & PWM  Rich timer set including 8-bit timers (4 channels) and 16-bit timers (6 channels), programmable pulse generation, 8-bit PWM channels and a dedicated watch timer (WT) with selectable intervals.
• Analog  12-bit A/D converter with 15 input channels and up to 50 ksps sampling rate for sensor interfacing and analog monitoring.
• Interfaces & Connectivity  Multiple serial interfaces including UART (3 channels), SPI (2 channels), and USI0/1 (multi-mode UART + SPI + I2C sets) for flexible system integration.
• Peripherals & System Functions  Integrated 16-bit CRC/checksum generator (including auto CRC mode), buzzer driver, watchdog timer (WDT), and other system peripherals for reliable embedded control.
• I/O & Package  Up to 61 programmable I/O lines in a 64-pin LQFP package (64-LQFP, 14×14‑0.8 mm), surface-mount mounting—suitable for compact board layouts.
• Operating Conditions  Industrial temperature range from −40 °C to +85 °C, making the device suitable for a broad set of environmental conditions.

Typical Applications

• Home Appliances  Control of user interfaces, timing and sensor inputs for appliances; integrated ADC, timers and buzzer drive simplify board design.
• Industrial Control  I/O-rich control tasks, timer-driven sequences and CRC-checked communications for robust industrial systems.
• Sensor Hubs & Data Acquisition  Multi-channel 12-bit A/D conversion and multiple serial interfaces enable centralized sensor sampling and aggregation.
• Consumer Electronics  User interface control, communication with peripherals and audio/buzzer signaling in compact device form factors.

Unique Advantages

• Highly integrated peripheral set: A broad collection of timers, ADC, serial interfaces and system functions reduces external components and simplifies BOM.
• Flexible power and clocking: Wide 2.2–5.5 V supply range, internal 16 MHz oscillator and external oscillator support enable deployment across varied power domains and clocking requirements.
• Robust memory features: 64 Kbytes of Flash with ISP and specified endurance/retention characteristics supports field updates and long-term data reliability.
• Rich I/O density: Up to 61 programmable I/O lines in a compact 64-LQFP package supports complex control and interfacing needs without large packages.
• Designed for reliability: On-chip POR, LVR/LVI, watchdog and CRC/checksum generator support fault detection and system integrity.
• Industrial temperature range: −40 °C to +85 °C rating allows use in temperature-demanding environments.
