A96G150GR2

The A96G150GR2 is an advanced CMOS 8-bit microcontroller built around an M8051-compatible core (2-clock per cycle) and designed for a wide range of embedded control applications. It combines up to 64 Kbytes of on-chip Flash with integrated RAM, EEPROM, powerful analog and digital peripherals, and on-chip oscillator/clock circuitry to deliver a compact, flexible control solution.

Targeted at embedded systems that require integrated analog acquisition, multiple timers/PWM channels, display and high-current I/O drive, and robust system protections, the A96G150GR2 balances performance and integration across a broad operating voltage and temperature range.

Key Features

• Core M8051 8-bit architecture with 2-clock per cycle operation and a typical main-clock performance point at 16 MHz (minimum instruction execution time 125 ns @16 MHz).
• Memory 64 Kbytes on-chip Flash (ISP, 30,000 program/erase endurance), 2 Kbytes EEPROM (300,000 endurance, 10-year retention), 256 bytes iRAM and 2,304 bytes xRAM for data and stack.
• Analog 12-bit A/D converter with 13 input channels (28-TSSOP package) for precision sensor interfacing and data acquisition.
• Timers & PWM Multiple timers including one 8-bit BIT and WDT, one 8-bit timer (T0), and five 16-bit timers (T1–T5) with programmable pulse generation; 8-bit PWM is available for motor/actuator and buzzer control.
• Interfaces Rich serial connectivity: USI blocks providing USART/SPI/I2C functionality and USART channels for UART communication; receiver time-out and 0% error baud rate features are available for robust serial links.
• Display & Output Drivers Integrated LCD driver (up to 24 segments × 8 commons with selectable duty and internal/external resistor bias), LED driver / high-current ports (8) and dedicated buzzer output simplify UI and audio designs.
• System Reliability & Protections On-chip Power-On Reset (POR, reset release level 1.32 V), Low-Voltage Reset (16-level detection), Low-Voltage Indicator (13-level detection), CRC-16, and watchdog/timers for system safety and integrity.
• Low Power & Clock Power-saving modes including STOP and IDLE, internal RC oscillators (HSI/LSI variants) and support for external crystals (main and 32.768 kHz sub clock) for flexible power/performance trade-offs.
• Electrical & Environmental Wide supply range 1.8–5.5 V and an extended operating temperature range of ‑40 °C to +105 °C, enabling use across diverse environments.
• Package & I/O 28‑lead TSSOP package (173 mil) with 26 general-purpose I/O pins, suitable for compact board layouts.

Typical Applications

• Home Appliances: Drive motor and UI functions, manage sensor inputs and control routines using integrated timers, PWM and ADC resources.
• Consumer Electronics: Implement user interfaces, segment LCD displays and audio feedback with the LCD driver, LED/high-current ports and buzzer support.
• Industrial & Building Control: Perform multi-channel analog sensing and digital control in HVAC, lighting or small automation systems using the 12-bit ADC and robust timer set.
• Sensor Hubs & Data Acquisition: Aggregate and preprocess sensor data with the 12-bit A/D, on-chip RAM/EEPROM and serial interfaces for downstream communication.

Unique Advantages

• Highly integrated peripherals: On-chip Flash, EEPROM, RAM, ADC, LCD driver, PWM, multiple timers and serial interfaces reduce BOM and board complexity.
• Flexible power and clock options: Wide 1.8–5.5 V supply range with internal and external oscillator support enables optimized power/performance for varied designs.
• Robust data storage: Flash with ISP capability and EEPROM with high endurance and long retention support in-field updates and reliable non-volatile storage.
• Comprehensive system protections: POR, multi-level LVR/LVI, watchdog and CRC combine to improve system reliability and fault detection.
• Display and output ready: Built-in LCD drive, high-current LED ports and buzzer output accelerate user interface implementation without external driver ICs.
• Package and temperature flexibility: Compact 28-TSSOP footprint with extended temperature operation suits space-constrained and thermally varied applications.
