Clock circuit
Model number | Name | VCC | Features | Operating temperature | Package type | Alternative model | Alternative method |
HJ2116 | Low-Power Real-Time Clock Circuit | 1.8~5.5 | A low-power regulated power supply featuring crystal‑oscillator stop‑detection and latching, with a built-in digital time‑adjustment circuit and two crystal‑oscillator selection modes: 32 kHz and 32.768 kHz. | -55℃~125℃ | SOP8, TSSOP8 | RS5C372A | In-situ substitution |
HJZ129 | High-Temperature Dual-Channel 10 MHz Clock Source | 1.8~5.5 | It delivers a strong output drive current, features an adjustable clock frequency, requires few external components, and offers the advantages of high-temperature tolerance and low temperature drift. | -55℃~200℃ | F08-04B | In-house development | - |
HJ8563 | I²C Real-Time Clock/Calendar Chip | 1.8~5.5 | Programmable clock output frequency, with a maximum bus speed of 400 kbit/s. | -55℃~200℃ | CSOP08B | PCF8563 | In-situ substitution |
HJ2201 | High-precision, ultra-low-jitter clock timer | 3.0~18 | It integrates a highly stable RC oscillator and a binary counter. It supports both single-shot and continuous trigger modes. By using chip capacitors with ultra‑low temperature coefficients and pairing them with external low‑temperature‑coefficient resistors, the timing accuracy can be maintained within 800 ppm/°C across the entire temperature range. | -55℃~125℃ | 1 | In-house development | - |
