A96L534AE

The A96L534AE is a multi-chip package that combines a high-voltage line-interface logic IC with an advanced CMOS 8-bit M8051 microcontroller core. It integrates program flash, data flash, on-chip LDO and a rich set of analog and digital peripherals to address fire safety and line-interface applications such as smoke detectors and related safety systems.

Designed for low-power, cost-sensitive systems, the device provides a wide input-voltage range for direct line interfacing, on-chip power management, and built-in analog front-end blocks to simplify sensor and power-line connectivity.

Key Features

• Core & Clock  8-bit M8051-compatible CISC core with an internal 4 MHz RC oscillator (±3.0% over -40 to +85 °C).
• Memory  16 Kbytes of on-chip FLASH program memory with ISP/On-chip debug, 256 bytes internal RAM (iRAM) plus 768 bytes XRAM and 256 bytes Data Flash for non-volatile data storage.
• Power & Line Interface  Integrated LDO (3.0 V ± tolerance specified in datasheet) and logic VIN range for line interface (logic power supply 8.5 V to 42 V, signal inputs 0–42 V), enabling direct power-line connection and simplified BOM.
• Analog Front End  10-bit ADC with 5 input channels, two rail-to-rail OP-AMP channels and a programmable gain amplifier—suitable for sensor conditioning and analog signal acquisition.
• Timers & PWM  Three 16-bit timers/counters plus an 8-bit Basic Interval Timer and a Watchdog Timer provide timing, pulse generation and safety monitoring functions.
• Output Current Control  Constant sink current generator with 2 channels and 16-step selection (maximum sink current up to 274 mA) for driving alarm loads or discharge paths.
• Communications & Interfaces  USART (configurable UART or 8-bit SPI) and dedicated line-interface logic including a power line transceiver for system communications.
• System Reliability  On-chip POR, low-voltage reset with multi-level detection, flash CRC/checksum generator (auto and user modes) and watchdog timer for robust operation in safety systems.
• Low Power Modes  STOP and IDLE power-down modes and low standby current (specified low-power consumption in datasheet) for battery-backed or low-energy designs.
• Package & Temperature  16-SOPN surface-mount Pb-free package (150 mil), operating temperature range -40 to +85 °C.

Typical Applications

• Fire Safety Systems  Integrated MCU, analog front end and line interface simplify smoke detector control, alarm drive and system diagnostics.
• Smoke Detectors  On-chip ADC, OP-AMPs and data flash enable sensor signal conditioning, event logging and firmware updates for detector electronics.
• Line-Interface Devices  Wide logic VIN range and power-line transceiver support direct connection to high-voltage lines and simplify external power-management circuitry.
• Battery-Backed Safety Modules  Low-power modes, watchdog and reset features support reliable standby operation and safe recovery after power events.

Unique Advantages
