A96G181HD

The A96G181HD is an 8-bit CMOS microcontroller based on the M8051 core with 2-clock-per-cycle operation. It combines compact memory, mixed-signal peripherals and reliable power management to address battery-operated and embedded applications such as electric shavers, LED lighting, battery chargers/protection, wireless vacuum cleaners, home automation, IoT and sensor nodes.

Designed for low-voltage systems, the device delivers on-chip FLASH with in-system programming, an internal oscillator, a 12-bit A/D converter, multiple timer/PWM channels and watchdog functionality—providing a highly integrated solution for space- and power-constrained designs.

Key Features

• Core & Performance 8-bit M8051-compatible CPU with 2-clock per cycle operation and a minimum instruction execution time of 125 ns (@16 MHz).
• Memory 2 Kbytes on-chip FLASH with ISP support, 30,000 erase/write endurance and 10-year data retention, plus 256 bytes of internal RAM (IRAM).
• Timers & PWM Multiple timers including Basic Interval Timer (BIT), Watchdog Timer (WDT), one 8-bit timer (T0) and two 16-bit timers (T1/T2). Supports 8-bit PWM (T0) and 16-bit/16-bit complementary PWM (T1/T2) for motor and power control tasks.
• Analog 12-bit A/D converter with input channels suitable for sensor interfacing and battery monitoring (HD variant provides up to 6 ADC input channels as specified for the HD package).
• Power Management & Reset Wide operating voltage range from 1.8 V to 5.5 V, Power-On Reset (POR) with reset release level at 1.32 V, multiple Low Voltage Reset (LVR) and Low Voltage Indicator (LVI) thresholds to support robust battery operation.
• Clocking Internal RC oscillators: HSI 32 MHz (with specified temperature-dependent tolerances) and LSI 128 kHz, enabling operation across the supported temperature range and simplifying board-level clock design. Typical internal RC operation supports system clocking up to 16 MHz.
• System Reliability & Safety Window watchdog timer, multiple interrupt sources (external interrupts, timers, ADC, WDT, BIT, LVI) and power-down modes (STOP, IDLE) for reliable embedded control and low-power management.
• Package & Environmental Range Available in compact 8-SOP (150 mil) surface-mount package. Device supports wide operating temperatures as specified (-40 to +85 °C) suitable for challenging environments.

Typical Applications

• Home Appliances Control and user-interface management for appliances such as electric shavers and wireless vacuum cleaners using integrated timers, PWM and ADC resources.
• LED Lighting Dimming, current sensing and user-control logic leveraging 12-bit ADC accuracy and PWM outputs for efficient LED drive.
• Battery Chargers & Protection Battery voltage monitoring, low-voltage detection and safety watchdog functions ideal for compact charger and protection circuits.
• IoT & Sensor Nodes Sensor interfacing and low-power operation for IoT endpoints and environmental sensors using internal ADC channels and low-current characteristics.
• Embedded Motor Control Small motor control and timing tasks using 16-bit timers and complementary PWM outputs for precise drive control.

Unique Advantages

• Highly integrated mixed-signal platform: On-chip FLASH, IRAM, 12-bit ADC, timers and PWM reduce external components and simplify BOM.
• Field update capability with longevity: In-system programmable FLASH with 30,000-cycle endurance and 10-year retention supports firmware updates and long-term deployments.
• Optimized for low-voltage, battery-powered designs: 1.8–5.5 V operation plus low current characteristics and multiple low-voltage detection levels improve battery runtime and safety.
• Flexible internal clocking: Built-in HSI and LSI oscillators remove the need for an external crystal in many designs, accelerating time-to-market and saving board space.
• Compact, robust packaging: 8-SOP surface-mount package and broad operating temperature support fit space-constrained and harsh-environment applications.
