Key Features

• Core — 8051-based 8-bit microcontroller running at up to 16 MHz, suitable for a wide range of embedded control tasks.
• Memory — 64 Kbytes of on‑chip FLASH program memory and 4.25 Kbytes of RAM provide nonvolatile code storage and runtime data space.
• Analog — Integrated 12‑bit A/D converter for precise analog sensor interfacing and measurement.
• Timers & PWM — Multiple timer and PWM resources including six 16‑bit PWMs, two 8‑bit PWMs, six 16‑bit timers and two 8‑bit timers to support motor drive, PWM dimming and timing functions.
• Connectivity & I/O — SPI and UART serial interfaces plus 41 general-purpose I/O pins for flexible peripheral and sensor connections.
• Power & Reliability — Integrated LDO, POR (power‑on reset), watchdog timer (WDT) and multiple power saving modes to support reliable startup and low power operation across 1.8–5.5 V supply range.
• Oscillator Options — Support for both internal and external oscillators to match system clocking needs.
• Package & Temperature — Available in a 44‑MQFP (10×10‑0.8 mm) package and specified for operation from −40 to 85 °C.

Typical Applications

• Embedded control systems — Use the MC97F2464Q for general-purpose control tasks that require firmware stored in on‑chip Flash and multiple timers/PWM channels.
• Sensor interfacing — The 12‑bit ADC and abundant I/O make it suitable for reading and processing analog sensors in instrumentation and monitoring equipment.
• Power‑sensitive devices — Built‑in power saving modes, LDO and POR support low power designs across a wide supply range.
• User interface and I/O management — 41 I/O lines with UART and SPI support allow integration of displays, keypads and serial peripherals.

Unique Advantages
