A96L414FU

The A96L414FU is an 8-bit CMOS microcontroller in the A96L41x series from Abov, built around an 8051-compatible M8051 core. It combines an 8 Kbyte on-chip Flash program memory with integrated analog and timing peripherals tailored for fire alarm and single-type smoke detector systems.

Designed to deliver a compact, robust control platform, the device integrates ADC, operational amplifiers, constant-current drivers and timers to simplify sensor interface, alarm drive and system monitoring in smart alarm implementations.

Key Features

• Core and Performance — 8-bit CISC M8051 core (8051 compatible) with an internal RC oscillator running at 4 MHz (±3.0% at -40 to +85 °C).
• Program and Data Memory — 8 Kbytes on-chip FLASH with in-system programming/multi-programming capability; 256 bytes IRAM and 256 bytes XRAM (512 bytes total); 256 bytes data flash (EEPROM).
• Analog and Sensor Interface — 10-bit A/D converter with 7 input channels and two rail-to-rail operational amplifiers for direct sensor conditioning; band-gap reference (VBGR) ~0.92 V ±3% (TA = 25 °C).
• Power Management — On-chip LDO (nominal 2.32 V ±3.45% at TA = 25 °C), support for STOP and IDLE power modes, and operating supply range of 2 – 3.6 V.
• Timers and PWM — Basic Interval Timer (8-bit), Watchdog Timer (8-bit), and three 16-bit timers (T0/T1/T2); 16-bit PWM generation for alarm or actuator drive.
• Drive and Safety Features — Two-channel constant sink current generator with 16-step selection and up to 274 mA maximum sink per channel; 16-bit CRC/checksum generator for data integrity.
• Serial Connectivity — USART (configurable as 8-bit UART or 8-bit SPI) and I2C support as provided in device feature set for external device communication.
• I/O and Packaging — 18 GPIO pins; available in a 20-QFN (4 × 4 mm) surface-mount package; operating temperature range -40 to 85 °C.

Typical Applications

• Standalone Smoke Detectors — Integrated ADC, op-amps and current sink drivers enable direct sensor interfacing and alarm drive for single-type smoke detectors.
• Fire Alarm Systems — On-chip timers, CRC and communications (USART/SPI/I2C) support local alarm control, monitoring, and data integrity functions within fire alarm modules.
• Smart Alarm Implementations — Flash multi-programming and data flash allow in-field updates and configuration for intelligent alarm behaviors.

Unique Advantages

• Highly Integrated Analog Front End: ADC with seven channels plus two rail-to-rail op-amps and a band-gap reference reduce external components required for sensor conditioning.
• Direct Alarm Drive Capability: Two-channel constant sink current generator (16-step, up to 274 mA) provides selectable, reliable drive for indicators and alert circuits.
• On-Chip Non-volatile Storage and ISP: 8 Kbytes of Flash with in-system programming and 256 bytes of data flash enable field updates and configuration storage without external memory.
• Comprehensive Timing and Safety: Multiple timer channels, watchdog and interval timer plus a 16-bit CRC/checksum generator support robust timing, supervision and data integrity.
• Compact Surface-Mount Package: 20-QFN (4 × 4 mm) package with 18 GPIOs provides a small footprint for space-constrained detector designs.
• Wide Operating Range: Operation across 2 – 3.6 V and -40 to 85 °C suits a broad range of environmental conditions common to alarm products.
