A96L416FU

The A96L416FU is an 8-bit CMOS microcontroller from Abov designed specifically for fire alarm and single‑type smoke detector systems. Built around an 8051-compatible M8051 core with an integrated peripheral set, the device targets smart alarm applications that require a compact, robust, and cost‑effective semiconductor solution.

The device combines on‑chip Flash, mixed‑signal peripherals and power management features to simplify sensor interfacing, LED/alert drive and system control in standalone smoke detector and alarm designs.

Key Features

• Core & Memory — 8‑bit M8051-compatible core (2 clocks per cycle) with 16 Kbytes on‑chip Flash supporting multi‑programming. Internal data memory includes 256 bytes IRAM, up to 768 bytes XRAM and 256 bytes data flash.
• Clock & Performance — Internal RC oscillator at 4 MHz ±3.0% (TA = −40 to +85 °C), supporting device operation up to the specified operating conditions.
• Analog Signal Chain — 10‑bit A/D converter with 7 input channels and 72 ksps capability, plus two rail‑to‑rail operational amplifiers for sensor signal conditioning.
• Timers & PWMs — Three 16‑bit timers and three 16‑bit PWM channels for timing, pulse generation and alarm/output control; additional 8‑bit timers include a Basic Interval Timer and a Watchdog Timer.
• Drive & Power Management — Two‑channel constant sink current generator (16‑step selectable, up to 274 mA sink) and an on‑chip LDO (nominal 2.32 V ±3.45% at 25 °C) for simplified power and LED/current sink management.
• Communications & Peripherals — One USART (configurable as 8‑bit UART or 8‑bit SPI) for external device communication, a 16‑bit CRC/checksum generator, and a 32 kHz oscillator option for real‑time timing functions.
• GPIO & Packaging — 18 general‑purpose I/O pins in a compact 20‑QFN (4 × 4 mm) package optimized for surface‑mount designs.
• Reliability & Power Safety — Power‑on reset, selectable low voltage reset detection levels, and industrial temperature rating (−40 to +85 °C) for dependable operation in alarm systems.

Typical Applications

• Standalone Smoke Detectors — Integrated analog front end, ADC and op‑amps enable direct sensor interfacing and event detection in single‑type smoke detector designs.
• Fire Alarm Control Modules — Timers, PWMs and constant current sinks support alarm signaling, LED and horn drive, and timed control functions.
• Smart Alarm Devices — On‑chip Flash, USART communications and CRC support firmware updates, device diagnostics and secure data handling in smart alarm implementations.
• Sensor Conditioning and Signal Processing — Two rail‑to‑rail op‑amps with a 10‑bit ADC provide the analog and conversion resources for reliable sensor signal acquisition and processing.

Unique Advantages

• Highly integrated smoke‑detector platform: On‑chip Flash, ADC, op‑amps, PWMs, timers and constant current sinks reduce external components and simplify BOM for detector designs.
• Flash with multi‑programming: 16 Kbytes of on‑chip Flash enables field programming and iterative firmware development for evolving alarm features.
• Robust analog front end: 10‑bit ADC (7 channels) plus dual rail‑to‑rail op‑amps support accurate sensor measurement and conditioning without large external circuitry.
• Power and output flexibility: Integrated LDO and selectable constant sink current generator (up to 274 mA) simplify power sequencing and drive for indicators and alarms.
• Industrial temperature and reset safety: −40 to +85 °C rating with POR and selectable low‑voltage reset levels help ensure reliable operation across typical alarm installations.
• Compact surface‑mount package: 20‑QFN (4 × 4 mm) footprint supports small, space‑constrained detector designs and automated assembly.
