ADUC843BCPZ8-5

8-bit 16MHz MCU, 62KB Flash, 8 ADC, I2C, SPI, UART, LFCSP

8-bit microcontroller featuring an 8052 core architecture operating at up to 16.78MHz. This integrated circuit offers 62KB of FLASH memory and 2.25KB of RAM, with an 8-channel, 12-bit Analog-to-Digital Converter (ADC) supporting an 8-channel PWM output. Connectivity is provided via I2C (2 channels), SPI (1 channel), and UART/USART (1 channel) interfaces, alongside 34 programmable I/Os. Designed for surface mounting in an LFCSP EP package, it operates from a 4.75V to 5.25V supply voltage and functions within a -40°C to 85°C temperature range.
