MAXIM INTEGRATED / ANALOG DEVICES MAX7221EWG LED Driver
The MAX7221EWG+ is a serially interfaced, 8-digit LED display driver in a 24-pin WSOIC package. It is a compact, common-cathode display driver that connects microprocessors to 7-segment numeric LED displays of up to 8 digits, bar graph displays, or 64 individual LEDs. The device includes an on-chip BCD code-B decoder, multiplex scan circuitry, segment and digit drivers, and an 8x8 static RAM for storing each digit. Only one external resistor is needed to set the segment current for all LEDs. It supports SPI, QSPI, and MICROWIRE interfaces with slew rate-limited segment drivers to reduce EMI. Individual digits can be addressed and updated independently, with options for code-B decoding or no decoding per digit. Features also include low power shutdown mode, brightness control, scan limit register for displaying from 1 to 8 digits, and a test mode that turns all LEDs on. The device operates with a supply voltage range of 4V to 5.5V, supports a 10MHz serial interface, and can control each LED segment individually. It ensures the display is blanked on power-up. Suitable for industrial applications and portable devices.
