Key Features

• Core 8-bit CISC M8051 core running up to 16 MHz for legacy-compatible embedded control.
• Memory 32 Kbyte on-chip Flash program memory with 256 bytes IRAM and 1,792 bytes XRAM for application code and runtime data.
• Touch Sensing 20-channel self-capacitive touch switch with 16-bit sensing resolution and single/multi-key detection modes.
• Analog 12-bit A/D converter with 8 external input channels plus 1 channel for internal reference voltage.
• LED Driver Integrated LED driver supporting 8 COM × 16 SEG (T/M-type combinations supported) with constant-current segment levels.
• Timers and PWM Multiple timers including 8-bit and 16-bit timers, PWM (8-bit, 16-bit) and a 16-bit pulse pattern generator for timing and waveform control.
• Connectivity Serial peripherals include 8-bit USART, SPI and I2C functionality (USI/USART implementations) for display, sensor and peripheral interfacing.
• System Reliability Watchdog Timer (WDT), Power-On Reset (POR), Low Voltage Reset (LVR) with multi-level detect and low-voltage indicator for robust startup and fault protection.
• Power and Clock Operates from 2.0 V to 5.5 V (device operation at 16 MHz); touch, ADC and LED driver operate from 2.7 V to 5.5 V. Internal and external oscillator options available.
• Package and Temperature Surface-mount 28‑TSSOP (173 mil) package; specified operating temperature −40 °C to +85 °C.

Typical Applications

• Capacitive touch user interfaces — 20-channel self-capacitive sensing provides multi-key and single-key detection for touch panels and keypad implementations.
• LED segment and indicator control — integrated 8COM × 16SEG LED driver simplifies segment and indicator displays with constant-current segment control.
• Embedded controller designs — 32 KB Flash, multiple timers, ADC and serial interfaces support general embedded control and sensor-interfacing tasks.

Unique Advantages

• Highly integrated touch and UI peripherals — 20-channel capacitive touch engine plus an onboard LED driver reduce external component count for user-interface designs.
• Comprehensive analog and timing resources — 12-bit ADC and multiple 8/16-bit timers provide the measurement and timing building blocks needed for control and sensing functions.
• Flexible serial interfaces — USART, SPI and I2C-capable USI provide options for communicating with displays, sensors and other peripherals.
• Wide voltage operating range — 2.0 V–5.5 V supply support at up to 16 MHz, with touch/ADC/LED driver operation specified from 2.7 V, enabling use across common embedded power rails.
• Design-ready package and temperature rating — available in 28‑TSSOP surface-mount package and rated for −40 °C to +85 °C operation for deployment in standard commercial and industrial environments.
