A96L116FUN

The A96L116FUN is an 8-bit CMOS microcontroller based on the M8051 core, featuring 16 Kbytes of on-chip Flash and a compact 20-pin QFN package. It is designed for flexible, cost-effective embedded control applications that require integrated analog, timer and communications peripherals in a small form factor.

With a 12-bit ADC, multiple 16-bit timers, low-power modes and a wide operating voltage range, the A96L116FUN delivers a balanced combination of performance, integration and low-voltage operation for sensor interfacing, real-time control and battery-powered designs.

Key Features

• Core M8051 8-bit core (8051 compatible) with 2 clocks per cycle and internal high-frequency RC oscillator (16 MHz HFIRC).
• Memory 16 Kbytes on-chip Flash program memory, 256 bytes iRAM and 768 bytes xRAM, plus 256 bytes of data flash for non-volatile data storage.
• Analog 12-bit A/D converter with up to eight input channels and a conversion time of 9 µs (at 2.7 V) for precise sensor measurement and data acquisition.
• Timers and Real-Time Three 16-bit timers/counters (T0/T1/T2), an 8-bit Basic Interval Timer (BIT) and a WatchDog Timer (WDT); includes Real-Time Clock/Calendar (RTCC) with hour/day/week/month/year counting.
• Interfaces Integrated serial interfaces including I2C (1-channel), SPI (1-channel) and a low-power UART for versatile peripheral and host communication.
• System Reliability & Utilities 16-bit CRC/checksum generator, 128-bit unique ID, power-on reset, low-voltage reset with multiple detection levels and low-voltage indicator.
• Clocking & Power Supports internal and external oscillators (HFIRC 16 MHz, LFIRC 40 kHz, and external crystal/ceramic options) and power-saving modes (STOP and IDLE) for low-power operation.
• I/O and Packaging 18 general-purpose I/O pins in a compact 20-QFN-0404 package (4 × 4 mm), operating over –40°C to +85°C and a supply range of 1.71 V to 3.6 V.

Typical Applications

• Sensor interfacing and data acquisition — Eight-channel 12-bit ADC and fast conversion times enable accurate capture of analog sensors in compact systems.
• Real-time control and scheduling — Multiple 16-bit timers and an on-chip RTCC support timed events, pulse generation and scheduled tasks.
• Low-power portable devices — Power-saving STOP/IDLE modes combined with wide low-voltage operation (down to 1.71 V) suit battery-powered designs.
• Embedded communications and HMI — I2C, SPI and low-power UART provide connectivity for peripherals, displays and simple user interfaces.

Unique Advantages

• Highly integrated analog and digital peripherals: 12-bit ADC, multiple timers, RTCC and CRC reduce external components and simplify PCB design.
• Compact, production-ready package: 20-QFN-0404 (4×4 mm) offers a small footprint for space-constrained applications while providing 18 GPIOs.
• Flexible clock system: Internal HFIRC (16 MHz) and LFIRC (40 kHz) plus external crystal/ceramic support enable optimized trade-offs between accuracy and power.
• Robust operating range: Wide supply voltage (1.71–3.6 V) and industrial temperature rating (–40°C to +85°C) for use across varied environments.
• On-board non-volatile data storage and ID: 256 bytes data flash for application data and a 128-bit unique ID for device tracking and identification.
