Product Attributes

Introduction

This device features ultra-low power consumption at 3.6V and supports a DC-DC converter for optimized efficiency. It integrates a 12-bit ADC, a low-power comparator, and an internal current reference. Certain models include an integrated LCD controller. It offers dedicated peripherals for metering applications and an integrated wireless transceiver. Built around a high-speed MCU core, it provides multiple memory options and digital peripherals, with support for multiple clock sources and on-chip debugging.

Features

• Ultra-low power consumption: operating current as low as 130 µA/MHz; sleep current as low as 110 nA (data retention mode).
• Fast wake-up: only 2 µs to wake from any sleep mode.
• 12-bit ADC: 16 channels, up to 75 ksps (12-bit mode) or 300 ksps (10-bit mode); integrated programmable gain amplifier, temperature sensor, and autonomous burst mode.
• Two low-current comparators: programmable hysteresis and response time, configurable as interrupt or reset source.
• Internal 6-bit current reference: output current up to ±500 μA with source and sink capability, PWM interpolation for enhanced resolution.
• Integrated LCD controller: supports up to 128-segment display with integrated charge pump for contrast control.
• Metering-specific peripherals: DC-DC buck converter, sleep-mode pulse accumulator with programmable switch debounce and pull-up control, and dedicated packet processing engine for wireless protocol acceleration.
• Integrated wireless transceiver: operating frequency range 240–960 MHz, receive sensitivity –121 dBm, multiple modulation schemes supported, maximum output power +20 dBm.
• High-speed MCU core: pipelined instruction architecture, most instructions execute in 1 or 2 system clock cycles.
• Rich memory and peripherals: up to 128 kB flash and 8 kB internal data memory; 53 port I/Os, multiple serial interfaces, and timers.
• Flexible clock sources: high-precision internal oscillator, low-power internal oscillator, external oscillator, and RTC oscillator with independent alarm function.
• On-chip debug: full-speed, non-intrusive in-system debugging with breakpoint and single-step execution support.
