A96G150SN

The A96G150SN is an advanced CMOS 8-bit microcontroller based on an M8051-compatible core with up to 64 Kbytes of on-chip Flash and integrated oscillator options. It combines multiple memories, a 12-bit ADC, a comprehensive timer/PWM subsystem, LCD/LED drivers and a broad set of communication interfaces to address embedded control and human‑machine interface designs.

Designed for flexible, low-power embedded applications — including consumer and home-appliance systems — the device delivers a high level of integration to simplify board design and reduce BOM count.

Key Features

• Core M8051 8-bit core (8051 compatible) with 2-clock-per-cycle operation and minimum instruction execution time of 125 ns at a 16 MHz main clock.
• Program and Data Memory 64 Kbytes on-chip Flash (in‑system programming supported, 30,000 write endurance), 2 Kbytes EEPROM (300,000 endurance, 10‑year retention), 256 bytes IRAM and 2,304 bytes XRAM for flexible code and data partitioning.
• Analog 12-bit A/D converter with up to 15 input channels (44-LQFP package) for precision sensor interfacing and data acquisition.
• Timers and Pulse Generation Multiple timers including one 8-bit basic interval timer, one 8-bit watchdog timer, one 8-bit T0 and five 16-bit timers (T1–T5). Programmable pulse generation, 8-bit PWM and dedicated buzzer channel enable motor, actuator and audio control.
• Communication Interfaces Dual USI channels providing USART/SPI/I²C functionality plus an additional USART/SPI channel (USART2) with receiver timeout and 0% error baud rate support for robust serial communications.
• GPIO and Display Up to 42 general-purpose I/O ports in the 44-LQFP package, with 8 high-sink current ports and an integrated LCD driver supporting 24 segments × 8 commons and selectable duty/bias and contrast control.
• System Reliability Watchdog Timer (WDT), Watch Timer (WT), CRC-16 engine, Power‑On Reset (POR), Low‑Voltage Reset (16-level) and Low‑Voltage Indicator (13-level) provide extensive fault detection and recovery features.
• Power and Clock Operates over a wide supply range (1.8–5.5 V with clock-dependent conditions), supports internal and external oscillators (internal RC: HSI 32 MHz, LSI 128 kHz; external crystal support) and includes STOP and IDLE power-down modes for low-power designs.
• Package and Temperature 44-LQFP (10 × 10 mm, 0.8 mm pitch) package and industrial operating temperature range of −40 to +85 °C.

Typical Applications

• Home Appliances — Control of motors, actuators and user interfaces using integrated timers, PWM/PPG and LCD/LED driver features.
• Display and User Interface — Drive segmented LCDs and high-current LED ports while managing menus and input via the abundant GPIO and USART/USI serial interfaces.
• Sensor Acquisition — Multi-channel 12-bit A/D converter combined with timers and CRC support for reliable sensor sampling and data integrity checks.
• Embedded Control — General embedded control tasks that benefit from on‑chip Flash/EEPROM, watchdog, POR/LVR/LVI and flexible clocking.

Unique Advantages

• Highly integrated memory system: 64 KB Flash with ISP plus 2 KB EEPROM and multiple RAM regions reduce external memory needs and simplify design.
• Rich peripheral mix: Multiple timers, PWM/PPG channels, buzzer output and LCD/LED drivers provide direct hardware support for motor control and user interfaces.
• Precise analog inputs: 12-bit ADC with up to 15 channels enables accurate sensor measurement without external ADC components.
• Robust reliability features: POR, multi‑level LVR/LVI, WDT/WT and CRC hardware improve system fault tolerance and diagnostics.
• Flexible power and clocking: Wide supply range (1.8–5.5 V), internal/external oscillator options and low‑power STOP/IDLE modes support battery and mains-powered designs.
• Production-ready package and temperature: 44-LQFP package and −40 to +85 °C operating range meet typical industrial and consumer product requirements.
