A96G166AE

The A96G166AE is an 8-bit CMOS microcontroller based on an M8051 CISC core, offering a flexible platform for embedded control applications. It combines a 16 Kbyte on-chip Flash program memory with integrated analog, timer and serial peripherals to simplify system design and reduce BOM.

Designed for efficient operation across a wide supply range (1.8–5.5 V) and temperature capability (–40 to +85 °C), the device targets applications that require reliable control, mixed-signal interfacing and low-power operation.

Key Features

• Core and Performance — 8-bit M8051 CISC core with operation up to a 16 MHz main clock (minimum instruction execution time 125 ns at 16 MHz).
• Flash Memory — 16 Kbytes on-chip Flash with in-system programming (ISP) and 30,000 write endurance for field-updatable firmware.
• RAM — 256 bytes of internal IRAM and 512 bytes of external XRAM for stack, variables and data buffers.
• Analog — 12-bit A/D converter with device-specific input configuration (A96G166AE provides 7 external ADC inputs and one internal reference channel).
• Timers and PWM — Multiple timers including 8-bit and 16-bit timers (T0/T1/T2), Basic Interval Timer (BIT), Watch Timer (WT) and programmable 16-bit PWM with dead-time control for pulse generation.
• Serial Interfaces — Dual USART channels (configurable for UART or SPI) and one I2C channel provide flexible serial connectivity for sensors, peripherals and modules.
• System Reliability — On-chip Power-on Reset (POR), Low Voltage Reset (LVR) with multi-level detection, Low Voltage Indicator (LVI) and Window Watchdog Timer for safe, robust operation.
• Oscillator and Clock — Internal RC oscillators (HSI 32 MHz and LSI 128 kHz ranges) plus support for external crystals allow flexible clocking options.
• Power Management — STOP and IDLE power-saving modes to reduce energy consumption in low-activity states.
• GPIO and Drive — 14 general-purpose I/O lines on the 16-SOPN (150 mil) package with dedicated high-sink port options noted in the device family.
• Operating Range and Package — Wide supply range 1.8–5.5 V, operating temperature –40 to +85 °C, supplied in a compact 16-SOPN (150 mil) package.

Typical Applications

• Embedded control — Core control tasks and firmware-updatable control logic for a wide range of embedded systems.
• Sensor interfacing and data acquisition — 12-bit ADC and multiple serial interfaces enable precise sensor readings and communication with external devices.
• Motor and actuator control in appliances — Timers, PWM and high-drive I/O support pulse generation and control of motors and power stages in consumer and appliance designs.
• User interface and communications — Dual USART channels and I2C facilitate display, keypad, and peripheral communications for appliance and consumer electronics interfaces.

Unique Advantages

• Highly integrated peripheral set: On-chip ADC, PWM/timers, dual USART and I2C reduce external component count and simplify PCB design.
• Field-updatable firmware: 16 Kbytes of Flash with in-system programming allows firmware updates without removing the device.
• Flexible power and clocking: Wide 1.8–5.5 V supply range, internal and external oscillator support, and STOP/IDLE modes enable adaptable power/clock strategies.
• Robust operation: Comprehensive reset and voltage monitoring (POR, LVR, LVI) plus window watchdog support improve system safety and reliability.
• Compact package with wide temperature range: 16-SOPN (150 mil) package and –40 to +85 °C capability suit space-constrained designs operating across wide temperature ranges.
• Designed for control applications: M8051 core with dedicated timers and PWM plus high-sink I/O options support common embedded control tasks.
