Smoke Detector IC
Description
The GW6310 is a highly flexible smoke detector IC with accurate smoke sensing AFE and long battery life power management circuit. GW6310 integrates 8051 compatible processor and peripherals for photoelectric smoke alarm, low power management, and communication. It includes accurate transimpedance amplifier (TIA), programmable gain amplifier (PGA), 12-bit ADC, LDOs for internal logic circuitry and MCU with IDLE, SLEEP, and RUN mode supported, highly reliable LED driver, two general purpose pulse width modulators (PWM), Power Line Communication (PLC) I/F, serial interfaces, and general purpose I/Os.
The GW6310 features 16KB of embedded Flash memory and 2KB of SRAM for program and data storage.
Multiple communication interfaces, such as UART, SPI and PLC, ensure efficient host device connectivity.
