ICM7228AIPIZ - Renesas Electronics

Description: The Intersil ICM7228 display driver interfaces microprocessors to an 8-digit, 7-segment, numeric LED display. Included on chip are two types of 7-segment decoder, multiplex scan circuitry, LED display segment drivers, LED display digit drivers and an 8-byte static memory as display RAM. Data can be written to the ICM7228A and ICM7228B's display RAM in sequential 8-digit update or in single-digit update format. Data is written to the ICM7228C display RAM in parallel random access format. The ICM7228A and ICM

ICM7228AIPIZ Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by VDD, and then the input clock signal. This ensures proper initialization of the device.
  • To minimize noise and EMI, it is recommended to keep the analog and digital grounds separate, use a solid ground plane, and keep the clock signal traces short and away from sensitive analog signals.
  • The ICM7228AIPIZ can support clock frequencies up to 100 MHz, but the maximum frequency may vary depending on the specific application and system requirements.
  • To configure the ICM7228AIPIZ for differential clocking, connect the differential clock inputs to the CLKIN+ and CLKIN- pins, and set the CLK_SEL pin to select the differential clock input.
  • The typical power consumption of the ICM7228AIPIZ is around 20-30 mA, depending on the clock frequency and output load.
