AT89C51RD2-SLSIM Allgemeine Beschreibung

Operating at a maximum frequency of 33MHz, this microcontroller is suitable for tasks that require high processing speeds. Its 4 8-bit ports and 32 I/O lines provide ample connectivity options, while the 8-channel 10-bit A/D converter ensures accurate and efficient analog-to-digital conversion. To optimize energy usage and prolong battery life, the AT89C51RD2-SLSIM features a power-down mode, idle mode, and power-off wake-up feature
