The MAX7219EWG by Analog Devices is a serial input/output common-cathode display driver designed to interface microprocessors with 7-segment numeric LED displays. It can drive up to 8 digits, bar-graph displays, or 64 individual LEDs. The device includes on-chip BCD code-B decoding, multiplex scan circuitry, segment and digit drivers, and an 8x8 static RAM.
Key features include a convenient 4-wire serial interface, individual LED segment control, and decode/no-decode digit selection. It operates over a voltage range of 4V to 5.5V and has a wide operating temperature range of -40°C to 85°C. A low-power shutdown mode of 150μA is available, and it offers both digital and analog brightness control.
This display driver is available in a 24-SOIC package and is suitable for surface mount applications. The MAX7221 variant is compatible with SPI, QSPI, and MICROWIRE interfaces and features slew-rate-limited segment drivers to reduce EMI. Applications include bar-graph displays, industrial controllers, panel meters, and LED matrix displays.
