CDP68HC68T1M2Z96 - Renesas Electronics

Description: The CDP68HC68T1 Real-Time Clock provides a time/calendar function, a 32 byte static RAM, and a 3 wire Serial Peripheral Interface (SPI Bus). The primary function of the clock is to divide down a frequency input that can be supplied by the on-board oscillator in conjunction with an external crystal or by an external clock source. The internal oscillator can operate with a 32kHz, 1MHz, 2MHz, or 4MHz crystal. An external clock source with a 32kHz, 1MHz, 2MHz, 4MHz, 50Hz or 60Hz frequency can be used to drive t

CDP68HC68T1M2Z96 Frequently Asked Questions (FAQs)

  • The recommended oscillator crystal frequency for the CDP68HC68T1M2Z96 is 16 MHz or 20 MHz, depending on the specific application and clock speed requirements.
  • The WDT on the CDP68HC68T1M2Z96 can be configured using the WDTCSR (Watchdog Timer Control and Status Register). You need to set the WDTCSR.WDE (Watchdog Timer Enable) bit to enable the WDT, and then set the WDTCSR.WDP (Watchdog Timer Prescaler) bits to select the desired timeout period.
  • The maximum current consumption of the CDP68HC68T1M2Z96 depends on the operating frequency, voltage, and other factors. According to the datasheet, the maximum current consumption is approximately 15 mA at 5V and 16 MHz operating frequency.
  • The CDP68HC68T1M2Z96 has 1 KB of internal EEPROM. To use it, you need to enable the EEPROM by setting the EECON.EEPE (EEPROM Enable) bit. Then, you can read and write data to the EEPROM using the EECON.EEWE (EEPROM Write Enable) bit and the EEPROM address registers.
  • The BOD on the CDP68HC68T1M2Z96 is a feature that detects when the supply voltage falls below a certain threshold (typically 4.5V or 4.2V) and resets the microcontroller to prevent malfunction or data corruption. You can configure the BOD threshold and enable/disable it using the BODCSR (Brown-Out Detector Control and Status Register).
