A96L416AE

The A96L416AE is an 8-bit CMOS microcontroller from Abov based on an 8051-compatible core with 16 Kbytes of on-chip Flash. It is designed as a complete semiconductor solution for fire alarm and single-type smoke detector systems and for use in smart alarm system designs.

With integrated analog, timing and power-management peripherals plus Flash multi-programming convenience, the device targets compact, robust and cost-effective smoke-detection and fire-alarm electronics.

Key Features

• Core & Memory — 8-bit M8051-compatible core running from a 4 MHz internal RC oscillator; 16 Kbytes on-chip Flash program memory and 1 Kbyte RAM for application code and runtime data.
• Analog & Power — 10-bit ADC with 5 input channels tailored for sensor interfacing, two rail-to-rail operational amplifiers, integrated LDO and internal reference (VBGR / LDO characteristics detailed in datasheet).
• Timers & Pulse Generation — Three 16-bit timers (T0/T1/T2) and two 16-bit PWM channels for pulse generation and timing control; also includes an 8-bit basic interval timer and a watch dog timer for system reliability.
• Interfaces & GPIO — Single USART (configurable for UART or SPI), up to 14 GPIO pins for sensor and actuator connections, and an optional 32 kHz oscillator for low-frequency timing.
• Constant Current Generator — Two-channel constant sink current generator with 16-step selection and maximum sink current up to 274 mA for driving indicators or alert loads.
• System Reliability — 16-bit CRC/checksum generator, power-on reset with defined release level, selectable low-voltage reset thresholds, and STOP/IDLE low-power modes.
• Operating Conditions & Packaging — Operates from 2.0 V to 3.6 V over −40 °C to +85 °C; supplied in a 16-SOPN (150 mil) surface-mount package suited for compact detector PCBs.

Typical Applications

• Standalone Smoke Detectors — Designed to implement single-type smoke detector electronics with on-chip ADC, op-amps and alert driver capabilities.
• Fire Alarm Modules — Suitable for fire alarm control and sensor-interfacing modules that require reliable timing, communication and current-driven alert outputs.
• Smart Alarm Systems — Enables compact smart alarm endpoints where integrated Flash, low-power modes and peripheral set reduce external component count.

Unique Advantages

• Flash multi-programming convenience: 16 Kbytes of on-chip Flash supports in-system programming workflows for rapid firmware updates and deployment.
• Highly integrated analog front end: 10-bit ADC (5 channels) plus two rail-to-rail op-amps and internal references reduce BOM and simplify sensor signal conditioning.
• Built-in alert drive capability: Dual constant-sink current generator with up to 274 mA per channel provides scalable control for LEDs or alert loads without large external drivers.
• Robust system features: Watch dog timer, CRC/checksum generator, power-on/low-voltage reset and selectable power modes help maintain reliable operation in safety-critical detectors.
• Compact, manufacturable package: 16-SOPN surface-mount package (150 mil) supports space-constrained PCB layouts typical of smoke detector designs.
