Key Features

• Core  M8051 8-bit CISC CPU running up to 12 MHz (12,000,000 Hz).
• Memory  48 Kbytes of in-system programmable Flash plus 1,280 bytes of SRAM (256 bytes IRAM + 1 Kbyte XRAM).
• Power and Clock  Wide supply range from 1.8 V to 5.5 V; on-chip power-on reset (POR), low-voltage reset/detect (LVR/LVI), and internal oscillators (including an HFIRC and LFIRC) for flexible clocking and reliable startup.
• Analog  12-bit A/D converter (2 channels) for accurate sensor interfacing.
• Timers and PWM  Multiple timers including 8/16-bit timer/counters, a basic interval timer, watch timer and 16-bit PWM for motor, timing and waveform tasks.
• Display and UI  Integrated LCD driver (32 segments × 8 commons) and buzzer driving port for compact user-interface implementations.
• Communications and I/O  UART connectivity and 43 general-purpose I/O lines to support a wide range of peripherals and board-level functions.
• IR and Carrier  Built-in transistor for IR LED drive plus carrier generation for remote-control designs and IR signaling.
• Reliability and Safety  Watchdog timer (WDT), CRC/checksum generator (16-bit) and on-chip reset circuitry to help improve system robustness.
• Package and Environment  Available in a 48-LQFP package (7 × 7 mm, 0.5 mm pitch) and specified for operation from −40 °C to 85 °C.

Typical Applications

• Home Appliances  Control user interfaces, display panels and sensor inputs in appliances using the integrated LCD driver, ADC and timers.
• Industrial Control  Implement compact control nodes with reliable reset, watchdog and industrial temperature operation for industrial environments.
• Remote Controls and IR Devices  Drive IR LEDs and generate carrier signals using the built-in IR transistor and carrier generator for remote-control products.
• Embedded User Interfaces  Combine LCD driving, buzzer output and multiple GPIOs to handle display, input and alert functions in consumer and industrial devices.

Unique Advantages

• Highly integrated peripheral set: On-chip LCD driver, 12-bit ADC, PWM, timers and CRC generator reduce external components and simplify system design.
• Flexible power and clocking: Internal HF and LF oscillators plus a wide 1.8–5.5 V supply range support diverse power architectures and runtime scenarios.
• Robust system features: POR, LVR/LVI and watchdog timer provide reliable startup and fault recovery for embedded applications.
• Compact package with abundant I/O: 43 general-purpose I/Os in a 48-LQFP (7×7 mm) package enable rich feature sets in small boards.
• Designed for user interfaces and remote control: Built-in IR LED drive transistor, carrier generator and buzzer port streamline implementation of consumer-facing controls.
• Pb-free packaging: Supplied in lead-free package options to support modern manufacturing requirements.
