Model | name | VCC | IQ/Max | characteristic | Operation temperature | Packaging form | Alternative models | Alternative methods |
HJ2116 | Low power real-time clock circuit | 1.8~5.5 | 0.4 | Internally integrated with a low-power regulated power supply, it has the function of crystal oscillator stop detection latch, which can detect the validity of internal clock data by detecting this bit. Built in digital time adjustment circuit ensures high accuracy of clock timing, and there are two crystal oscillator selection modes: 32KHz and 32.768KHz. | -55℃~125℃ | SOP8、TSSOP8 | RS5C372A | In situ substitution |
HJZ129 | High temperature dual channel 10MHz clock source | 1.8~5.5 | 5 | Strong output driving current, adjustable clock frequency, few external components, with the advantages of high temperature resistance and small temperature drift | -55℃~200℃ | F08-04B | Self developed | - |
