It packs 62 KB of program Flash, 2.25 K x 8 of RAM, and a full set of mixed-signal peripherals: an 8-channel 12-bit ADC and dual 12-bit DAC. On-chip peripherals include DMA, a programmable PWM, a temperature sensor, and a watchdog timer. Connectivity covers I²C, SPI, and a UART/USART. The part is housed in a 56-lead LFCSP-VQ (8x8 mm) package and operates over the industrial temperature range of -40°C to 85°C on a 2.7 V to 3.6 V supply. ## What the 8.38 MHz clock and integrated converters mean for your design The 8.38 MHz core clock is modest by today's standards, but this part is not a general-purpose number cruncher — it is a mixed-signal controller. The 12-bit ADC samples at rates that match slow-to-moderate sensor signals (temperature, pressure, strain gauges) without needing an external converter. The dual 12-bit DAC gives you two analog output channels for set-point generation or closed-loop trim. If your firmware loop needs to service the ADC, update the DAC, and handle a UART at the same time, the 8.38 MHz clock leaves enough headroom for most industrial control loops. It is ROHS3 compliant. The ADUC842BSZ62-3 shares the same 8.38 MHz speed and 2.7 V supply but in a different package (BSZ suffix). Confirm the package code against your board footprint before substituting.","metaTitle":"ADUC841BCPZ62-3 MicroConverter 8-bit MCU, 62KB Flash","metaDescription":"ADUC841BCPZ62-3 8-bit 8052 MCU with 62KB Flash, 2.25K RAM, 8x12b ADC, 2x12b DAC.
