A96L533AE

The A96L533AE is a multi-chip package (MCP) integrating a CMOS 8-bit M8051 core and a high-voltage line interface logic IC, designed for embedded fire-safety and power-line transceiver applications. It combines on-chip nonvolatile code storage, analog front-end resources and line-interface functions to provide a compact, low-power and cost-effective solution for smoke detectors and power-line communications.

Key Features

• Core — 8-bit M8051 compatible CISC CPU with a 4 MHz internal RC oscillator (4 MHz ±3.0% across −40 to +85 °C).
• Memory — 8 Kbytes on-chip FLASH program memory with on-chip ISP and self-program capability; 512 bytes IRAM and 256 bytes EEPROM/Data Flash for persistent parameters and configuration.
• Power and Voltage — Wide VIN supply range (8.5–42 V) with integrated LDO (3 V) for MCU domain and multi-level low-voltage reset (LVR) and POR functions.
• Timers & Watchdog — Multiple timers including 16-bit timer/counters, basic interval timer and an 8-bit watchdog timer for system supervision and pulse generation.
• Analog & Data Conversion — 10-bit ADC with 5 input channels, dual rail-to-rail operational amplifiers and a programmable gain amplifier for sensor conditioning and signal acquisition.
• Line Interface & Current Sink — Integrated power-line transceiver functionality and a constant current sink generator with 16-step selection (max. 274 mA sink capability) for driver loads and alarm signaling.
• Interfaces & Connectivity — USART (configurable as UART or 8-bit SPI) and general-purpose I/O (12 pins) for peripheral control and user interfaces.
• System Reliability & Integrity — Flash CRC/checksum generator (auto and user modes), watchdog timer, POR/LVR and multiple reset levels to maintain reliable operation in safety-critical systems.
• Low-Power Operation & Modes — Idle and STOP power-down modes and low quiescent current operation suitable for battery-backed and low-power designs.
• Package & Temperature — Surface-mount 16-SOPN (150 mil) package rated for −40 to +85 °C operating temperature.

Typical Applications

• Fire safety systems and smoke detectors — Integrated MCU, ADC, op-amps and line-interface features enable compact detector controllers with local sensing, alarm drive and system supervision.
• Power-line transceivers — On-chip high-voltage line logic and integrated transceiver functions simplify designs that communicate over power lines for monitoring and control.
• Sensor signal conditioning — 10-bit ADC, programmable gain amplifier and rail-to-rail op-amps allow direct interfacing to analog sensors in embedded monitoring applications.

Unique Advantages

• Highly integrated solution: Combines MCU core, FLASH, ADC, op-amps, LDO and high-voltage line-interface logic to reduce BOM and board area in safety and line-communication products.
• Wide input voltage tolerance: 8.5–42 V VIN supply range with on-chip LDO enables direct operation from a broad set of system power sources, simplifying power architecture.
• Designed for safety-focused designs: Multiple reset levels, POR/LVR and watchdog support provide layered reliability for fire-safety and alarm applications.
• Integrated analog front end: 10-bit ADC, dual op-amps and PGA support accurate sensor capture and conditioning without large external analog blocks.
• On-chip integrity checks: Flash CRC/checksum generator supports application-level code integrity verification and validation workflows.
• Compact, production-ready package: 16-SOPN surface-mount package and −40 to +85 °C rating facilitate rugged deployment and automated assembly.
