A96R717CUN

The A96R717CUN is an advanced CMOS 8-bit microcontroller based on a high-speed 8051 CPU core, offering 24 Kbytes of on-chip Flash and a rich set of integrated peripherals for embedded control applications. It is designed for compact, low-power systems requiring mixed-signal integration and user-interface support.

Typical use cases include home appliances and industrial control where on-chip A/D conversion, LCD drive and IR output simplify hardware design while maintaining operation across a wide 1.8–5.5 V supply and an industrial temperature range.

Key Features

• Core  The device integrates a high-speed 8051 8-bit CPU suitable for legacy and new embedded control codebases.
• Clock and Oscillators  Supports external and internal oscillators, including an internal 8 MHz HFIRC (user trim) and an internal 32 kHz LFIRC; documented operating speeds include 12 MHz and 8 MHz options.
• Memory  24 Kbytes of on-chip Flash program memory with 768 bytes of SRAM (256 bytes IRAM + 512 bytes XRAM) for stack, variables and data buffers.
• Analog  12-bit A/D converter with multiple inputs for sensor interfacing and signal monitoring.
• Display and IR Drive  Integrated LCD driver (32 segments × 8 commons as documented) and a built-in transistor for IR LED drive, enabling compact user-interface and remote-control designs.
• Timers and PWM  Multiple timer resources including 16-bit and 8-bit timers/counters, basic interval timer and 16-bit PWM for control, timing and waveform generation.
• System Reliability and Safety  On-chip Power-On Reset (POR), Low Voltage Reset (LVR/LVI) and a watchdog timer to improve system robustness.
• Data Integrity  16-bit CRC/checksum generator for data verification and communication integrity.
• Interfaces and I/O  UART connectivity plus up to 43 general-purpose I/O pins with additional shared I/O for LCD signals and carrier generation, buzzer drive and other peripheral control.
• Low Power Modes  Power-down modes and internal oscillators that support reduced power operation for battery-powered or energy-sensitive designs.
• Electrical and Environmental  Wide supply range of 1.8–5.5 V and an operating temperature range of −40 to 85 °C.
• Package  Available in a compact 48-QFN package (7 × 7 mm, 0.5 mm pitch) suitable for surface-mount assembly.

Typical Applications

• Home Appliances  User-interface control and sensor monitoring using the on-chip LCD driver, A/D converter and timers for efficient appliance control.
• Remote Controls  Integrated IR LED drive transistor and carrier generation simplify IR transmitter designs for remote-control applications.
• Industrial Control  Wide supply range, watchdog and voltage-detection features support robust embedded control in industrial environments.
• Portable and Battery-Powered Devices  Low-voltage operation and power-down modes enable extended battery life in portable control and sensing products.

Unique Advantages

• Highly integrated peripheral set: Combines ADC, LCD driver, timers, PWM, CRC generator and IR drive in a single chip to reduce BOM and PCB area.
• Wide supply and temperature range: 1.8–5.5 V operation and −40 to 85 °C rating allow flexible deployment across consumer and industrial designs.
• On-chip system safety features: POR, LVR/LVI and a watchdog timer simplify design for reliable, fault-tolerant systems.
• Internal oscillators: Built-in HF and LF oscillators reduce the need for external clock components and speed time-to-market.
• Compact package: 48-QFN (7×7 mm) supports space-constrained designs while providing abundant I/O.

Why Choose A96R717CUN?
