A96G166GD

The A96G166GD is an 8-bit CMOS microcontroller based on the M8051 core, designed for flexible, cost-effective embedded control solutions. It integrates 16 Kbytes of on-chip Flash, a 12-bit ADC, multiple timers and communication interfaces to address compact control and sensing applications.

With up to 26 I/O pins, on-chip oscillator options, on-board power supervision (POR/LVR/LVI) and multiple power-saving modes, the A96G166GD is tailored for designs that require a balance of integration, low-voltage operation and system-level reliability.

Key Features

• Core 8-bit M8051 CISC core providing established instruction compatibility for embedded control firmware.
• Memory 16 Kbytes of on-chip FLASH with in-system programming (ISP) and documented endurance; 256 bytes of IRAM and 512 bytes of XRAM for code and data.
• GPIO and Drive Up to 26 general-purpose I/O pins with high sink current support on up to 8 ports for direct LED or driver interfacing.
• Timers and PWM Multiple timers including 8-bit and 16-bit timers, Basic Interval Timer, Watch Timer and Window Watch Dog Timer; programmable pulse generation and 16-bit complement PWM with dead-time control.
• Analog 12-bit A/D converter with multiple external input channels plus an internal reference channel for accurate sensor interfacing.
• Interfaces Serial communications including I2C and dual USART (configurable for UART or SPI) to connect displays, sensors and peripherals.
• Power, Clock and Low Power Modes Wide operating supply 1.8–5.5 V, internal RC oscillator (HSI 32 MHz) and low-speed internal clock (LSI 128 kHz), plus STOP and IDLE power-down modes for energy-efficient operation.
• System Reliability On-chip POR, Low Voltage Reset (LVR) with multiple detect levels, Low Voltage Indicator (LVI), CRC-16 module and window WDT for robust system supervision.
• Package and Environment Available in a 28-SOP (300 mil) surface-mount package and specified for operation from –40°C to +85°C.

Typical Applications

• Home Appliances — Control user interfaces, sensor inputs and actuators using integrated ADC, timers and high-current I/O ports for consumer appliance designs.
• Consumer and Industrial Control — Manage discrete control tasks, timing and serial peripheral communications with dual USART and I2C connectivity.
• Sensor and Interface Modules — Perform multi-channel analog sensing with the 12-bit ADC and handle local signal conditioning and communication.
• Power and Peripheral Drive — Implement PWM-based drive and pulse generation for buzzer, LED and peripheral control using on-chip timers and high-sink ports.

Unique Advantages

• Highly integrated peripheral set: Combines FLASH, IRAM/XRAM, ADC, timers, PWM and serial interfaces to reduce BOM and simplify board-level design.
• Wide supply range: 1.8–5.5 V operation supports low-voltage battery-powered designs as well as standard 3.3 V and 5 V systems.
• Flexible clocking: Internal 32 MHz RC and low-speed internal oscillator options enable designs without external crystals or with external clocking when required.
• Robust supervisory functions: POR, multi-level LVR/LVI and window WDT provide layered protection for reliable system operation in the field.
• In-system programmability: On-chip FLASH with ISP capability and documented endurance supports iterative firmware updates and in-field revisions.
• Industrial temperature capability: Specified for –40°C to +85°C operation to accommodate demanding environmental requirements.
