Key Features

• Core 8-bit M8051-compatible CPU with 2-clock-per-cycle operation and internal HSIRC running at 16 MHz; supported system frequencies include 2, 4, 8 and 16 MHz.
• Memory 64 KB on-chip Flash memory (10,000-cycle endurance) and 4 KB SRAM for program and data storage.
• Analog 12-bit A/D converter with 8 external input channels plus one internal reference channel for multi-channel sensor acquisition.
• Capacitive Touch & Force Sensing 23-channel self-capacitive touch sensing and 4 pairs of capacitive force sensing for advanced user-interface implementation; includes water-shield support (4-channel mesh) and touch key interrupt wake-up.
• Timers & PWM Multiple timer resources including a basic interval timer, watchdog timer, 8-bit and 16-bit timers, and PWM support (16-bit: 5 channels; 8-bit: 1 channel) for control and timing tasks.
• Interfaces Embedded serial interfaces per the device selection: I2C ×1, SPI ×2 and USART ×2 to support sensor, display and peripheral communications.
• Power, Reset & Clock On-chip power-on reset (POR), low-voltage reset (LVR) with selectable release levels and low-voltage indicators; on-chip RC oscillators including HSIRC (16 MHz) and LSIRC (32 kHz).
• Packaging & Environmental 28-SOP (300 mil) surface-mount package with 26 available I/O pins; operating voltage range 2.0–5.5 V and industrial temperature range −40 to +85 °C.

Typical Applications

• Home Appliances Responsive capacitive touch panels and user controls for appliances that require multi-key touch and force sensing with integrated MCU control.
• Consumer Electronics Embedded control and sensor interfacing where compact integration of ADC, timers and serial interfaces reduces system complexity.
• Touch-based User Interfaces Keypads, control panels and touch sensors benefiting from the device’s multi-channel self-capacitive touch and water-shield support for robust operation.

Unique Advantages

• Highly integrated touch and analog peripherals: Combines 23-channel touch sensing and a 12-bit, 8-channel ADC on the same MCU to minimize external components.
