Holtek launches the BA45F6752/6758 CO/ Gas detector MCU conforming to the new national standard

Sep 22 2021 2021-09 Power Holt Integrated Circuits Inc.

Holtek's new CO/ Gas detector MCU with integrated time and date recording, CO/ Gas Detection AFE and 16-bit Voice DAC - BA45F6752/BA45F6758, For LED display CO/ gas voice alarm (BA45F6752) and LCD display CO/ Gas voice alarm (BA45F6758) that need to record abnormal status or event time.

BA45F6752/6758 series has 8K×16 Flash ROM, 1024×8 RAM, 256×8 EEPROM, 10-bit PTM, 10-bit STM, multi-channel 12-bit ADC and SPI/I2C/UART communication interface. Built-in CO/ gas detection AFE integrates the self-test and amplification circuit required by CO/ gas Sensor, temperature Sensor can be used for CO Sensor temperature compensation, 16-bit Voice DAC can achieve voice alarm function, The built-in LCD/LED driver can be used for CO/ gas gas concentration display and independent powered perpetual calendar, which can significantly reduce the peripheral circuit components of the product and simplify the design.

The BA45F6752/6758 is available in a 48-pin LQFP single package and is fully pin compatible with the BA45F6742/6748. Compared with BA45F6742/6748, this series increases the memory capacity of Flash ROM and RAM and adds the perpetual calendar function, so that the CO/ gas detector is more perfect.
