A96L623AE

The A96L623AE is a system-on-chip combining a high-voltage power-line transceiver with an 8-bit M8051-compatible microcontroller and 8 Kbytes of on-chip flash. It is designed specifically for smoke detector and fire safety system applications, integrating power management, line communication, analog front-end, and MCU peripherals to simplify detector designs.

With on-chip 5.0 V LDO, built-in line interface comparator and transmit transistor, low-power modes and integrated analog peripherals, the A96L623AE targets compact, low-BOM solutions for line-communication smoke detectors and related fire-safety devices.

Key Features

• Core & Memory  M8051-compatible 8-bit core with an internal 4 MHz RC oscillator (±3% TA = -40 to +85 °C) and 8 Kbytes of on-chip FLASH (ISP). Internal RAM includes 256 bytes IRAM and 256 bytes XRAM plus 256 bytes data flash.
• Power & Line Transceiver  Built-in power-line transceiver supporting VIN up to 42 V, on-chip comparator for line Rx and Tx transistor for line transmit, plus a 5.0 V LDO for VDD to reduce external power components.
• Analog & Sensor Interfaces  Two rail-to-rail operational amplifiers, a 10-bit A/D converter with 5 input channels and sample-and-hold (ADC throughput 72 ksps), and an on-chip temperature sensor for system monitoring.
• Timers & Pulse Generation  Three 16-bit timers (T0/T1/T2) plus an 8-bit basic interval timer and watchdog timer; timers can be used for pulse generation and PWM-style control.
• Communications & I/O  Single-channel USART (UART or SPI selectable) and dedicated RXT/TXR circuitry for one-line communication. GPIO provided for detector control and sensor interfacing.
• Constant Current & Output Drivers  Two-channel constant sink current generator with 16-step selection and maximum sink current up to 287 mA, facilitating LED or horn drive designs.
• Low-Power Modes & Reliability  Power-down modes including STOP and IDLE along with SLEEP mode options to minimize power consumption in standby. Integrated power-on reset and low-voltage reset features improve system robustness.
• Package & Environmental  Available in a 16-SOPN surface-mount package (150 mil), rated for operation from -40 to +85 °C for deployment in a wide range of environmental conditions.

Typical Applications

• Smoke and Fire Detection Systems  Integrated MCU, ADC, op-amps and power-line transceiver make the device suitable for the control, sensing and communication functions required in smoke detectors and fire alarm units.
• Power-Line Networked Alarms  On-chip RXT/TXR line-communication circuitry and line comparator support one-line power-line communication between detectors or to a central controller.
• Mains-Powered or High-Voltage Supply Designs  Built-in 5.0 V LDO and VIN support up to 42 V enable direct integration with higher-voltage detector power input ranges while simplifying external power components.

Unique Advantages

• Highly integrated SoC: Combines MCU, power-line transceiver, ADC, op-amps and power management to reduce BOM and board area in detector designs.
• Wide VIN handling with on-chip regulation: Support for VIN up to 42 V plus a 5.0 V LDO enables flexible front-end power architectures.
• Dedicated line-interface circuitry: Comparator and transmit/receive transistor for the line interface simplify implementation of one-line communication over power wiring.
• Analog front-end and sensor support: Rail-to-rail op-amps and a 10-bit ADC (5 channels, 72 ksps) provide direct interfacing for smoke sensors and analog signal conditioning.
• Power and reliability features: Multiple low-power modes, watchdog timer, power-on reset and low-voltage detection enhance operational stability and energy efficiency.
• Compact package and broad temperature range: 16-SOPN surface-mount package rated -40 to +85 °C for compact, robust detector assemblies.
