ICM7218AIJI - Renesas Electronics

Description: The ICM7218 series of universal LED driver systems provide, in a single package, all the circuitry necessary to interface most common microprocessors or digital systems to an LED display. Included on-chip are an 8-byte static display memory, two types of 7-segment decoders, multiplex scan circuitry, and high current digit and segment drivers for either common cathode or common anode displays. The lCM7218A and 1CM7218B feature two control lines (WRITE and MODE) which write either 4 bits of control informatio

ICM7218AIJI Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by VDD, and then the clock signal. This ensures proper initialization of the device.
  • The thermal shutdown feature is enabled by default. If the junction temperature exceeds 150°C, the device will shut down. To handle this, ensure proper heat sinking and thermal management in your design.
  • The maximum clock frequency supported is 40 MHz. However, it's recommended to operate the device at a frequency below 30 MHz for optimal performance and to minimize power consumption.
  • Yes, the ICM7218AIJI is compatible with 3.3V systems. However, ensure that the input voltage (VCC) is within the recommended range of 2.7V to 5.5V.
  • The watchdog timer is enabled by setting the WDTEN bit in the control register. The timer period can be set using the WDTPER register. Consult the datasheet for specific implementation details.
