Key Features

• Core  High-speed 8-bit 8051-compatible CPU (M8051) implementation with 2 clocks per cycle.
• Memory  48 Kbytes of Flash program memory and 1.25 Kbytes (1,280 bytes) of SRAM (256 bytes IRAM + 1,024 bytes XRAM) for code and data storage.
• Clock & Oscillator  Supports internal and external oscillators; includes internal 8 MHz HFIRC (±1.0% trim) and internal 32 kHz LFIRC (±5.0%).
• Analog  12-bit A/D converter with 5 inputs for precision sensor interfacing.
• Display & IR Drive  Integrated LCD driver supporting 32×8 (32 segments × 8 commons) and a built-in transistor for IR LED drive to simplify remote-control and display subsystems.
• Timers & PWM  Multiple timers (8-bit and 16-bit), PWM and a watch timer for timing, carrier generation and motor or buzzer control.
• System Reliability  On-chip POR (Power-On Reset), LVR (Low Voltage Reset), LVI (Low Voltage Interrupt) and a Watchdog Timer (WDT) for robust system operation.
• Data Integrity  16-bit CRC/Checksum generator for error detection and integrity checks.
• I/O and Connectivity  59 I/O lines (13 dedicated I/O and 46 shared with LCD signals) and UART connectivity for serial communication.
• Power  Wide operating supply range from 1.8 V to 5.5 V and support for power-down modes to reduce power consumption.
• Package & Environment  Surface-mount 64-QFN package (9×9 mm, 0.5 mm pitch) and industrial temperature range of −40 °C to +85 °C.

Typical Applications

• Home Appliances  Control panels, user interfaces and sensor monitoring where integrated LCD driving, ADC inputs and timers simplify designs.
• Remote Controls & IR Systems  Embedded remote controllers using the built-in IR LED drive transistor and carrier generation features for IR transmission.
• Industrial Control  Low-voltage control systems and instrumentation benefiting from wide supply range, watchdog protection and CRC/Checksum generation for reliability.
• Consumer Devices  Buzzer control, timed events and serial interfaces for compact consumer electronics with display and sensor requirements.

Unique Advantages

• Highly integrated peripheral set: On-chip ADC, LCD driver, PWM, timers, CRC generator and IR drive reduce external components and BOM.
• Flexible power operation: 1.8 V to 5.5 V supply range plus power-down modes and on-chip reset/LV detection support designs across battery- and mains-powered products.
• Industry temperature support: Rated for −40 °C to +85 °C operation for use in industrial and demanding environments.
• Compact package: 64-QFN (9×9 mm) surface-mount package enables space-efficient PCB layouts for compact products.
• Built-in safety and integrity features: Watchdog Timer, POR/LVR/LVI and 16-bit CRC/Checksum generator improve system robustness and data integrity.
