A96L414FR

The A96L414FR is an 8-bit CMOS microcontroller from Abov’s A96L41x series, built on an M8051-compatible core and optimized for fire alarm and single-type smoke detector systems. It combines a compact 8 Kbytes Flash memory footprint with integrated analog, timing and power peripherals to simplify detector electronics design and deployment.

With on-chip oscillators, LDO, dual operational amplifiers, a 10-bit ADC and a programmable constant-current generator, the device targets compact, cost-effective smoke-detector and alarm implementations that require robust analog front-ends and streamlined BOM.

Key Features

• Core — 8-bit M8051-compatible CPU with 4 MHz internal RC oscillator (4 MHz ±3.0% over −40 to +85 °C); 2 clocks per cycle operation.
• Program Memory — 8 Kbytes on-chip Flash with multi-programming capability and ISP support for field and production programming.
• RAM and Data Flash — 0.5 Kbytes RAM (256 B IRAM + 256 B XRAM) and 256 bytes data flash for non-volatile parameter storage.
• Analog Front End — 10-bit ADC with 7 input channels at up to 72 ksps, plus 2 rail-to-rail operational amplifiers and an internal bandgap (V_BGR 0.92 V ±3%).
• Constant Current Generator & PWM — Two-channel, 16-step selectable constant sink current generator (max 274 mA) and 3 × 16-bit PWM channels for LED/actuator control and timing functions.
• Timers and RTC — Multiple timers including 3 × 16-bit timers (T0/T1/T2), basic 8-bit BIT timer and an 8-bit watchdog timer for reliable timing and supervision.
• Communications & Peripherals — USART supporting UART or SPI, CRC/16-bit checksum generator, I2C support and 18 GPIOs for sensor interfacing and system control.
• Power & Oscillators — On-chip LDO (2.32 V ±3.45% at 25 °C), internal 4 MHz RC oscillator and a 32 kHz oscillator; power-down modes (STOP, IDLE) for low-power operation.
• Operating Range & Package — Wide operating temperature −40 to +85 °C, operating voltage range up to 3.6 V, and available in a 20-pin TSSOP surface-mount package.

Typical Applications

• Single-type Smoke Detectors — MCU-level integration of ADC, op-amps and timing functions for compact detector front-ends and alarm logic.
• Fire Alarm Modules — Integrated constant-current sinks, PWMs and communications simplify LED/indicator control, alarm signaling and peripheral interfacing.
• Standalone Detector Electronics — On-chip LDO, internal oscillators and data flash support self-contained detector designs with simplified power and memory management.

Unique Advantages

• Highly integrated analog and power peripherals: Dual op-amps, 10-bit ADC and on-chip LDO reduce external components and simplify sensor front-end design.
• Built-in constant-current sink with high drive: Two selectable channels (up to 274 mA) provide flexible drive options for LEDs or other sinks without extra driver ICs.
• Compact memory and in-system programming: 8 Kbytes Flash with ISP and multi-programming capability streamlines production programming and firmware updates.
• Robust timing and supervision: Multiple 16-bit timers plus watchdog and BIT timers enable reliable timing, fault detection and pulse generation for alarm logic.
• Designed for detector environments: Extended −40 to +85 °C operating range and surface-mount 20-TSSOP package suit typical detector manufacturing and deployment conditions.
• Checksum/CRC support: On-chip 16-bit CRC generator helps ensure firmware and data integrity in the field.
