Max7219 led

Description: The MAX7219CNG is a compact, serial input/output common-cathode display driver that can interface microprocessors to 7-segment numeric LED displays of up to 8 digits, bar-graph displays, or 64 individual LEDs. Included on-chip are a BCD code-B decoder, multiplex scan circuitry, segment and digit drivers, and an 8x8 static RAM that stores each digit. Communication with the MAX7219 is achieved through a convenient 4-wire serial interface (supports SPI). Individual digits may be addressed and updated without rewriting the entire display. Only one external resistor is required to set the segment current for all LEDs. The IC also includes a 150μA low-power shutdown mode, analog and digital brightness control, a scanlimit register that allows the user to display from 1 to 8 digits, and a test mode that forces all LEDs on. This device comes in a 24-pin DIP package. Features: 10MHz Serial Interface Individual LED Segment Control Decode/No-Decode Digit Selection 150μA Low-Power Shutdown (Data Retained) Digital and Analog Brightness Control Display Blanked on Power-Up Drive Common-Cathode LED Display Slew-Rate Limited Segment Drivers for Lower EMI (MAX7221) SPI, QSPI, MICROWIRE Serial Interface (MAX7221) 24-Pin DIP package

A convenient four-wire serial interface can connect all common microprocessor. Each data can be addressed in the update does not overwrite all of the display. MAX7219 also allows the user to select each of the data code or not coded. The entire device includes a 150?A low-power shutdown mode, analogue and digital brightness control, a scan-limit register allows the user to 1-8 bits of data, there is a LED light so that all the detection mode. Requires only three IO ports can drive a dot! No flashing dot matrix display! Support cascade! Single module can drive a common cathode 8 * 8 dot matrix Module Operating voltage: 5V Module size: 5 cm X 3.2 cm wide X 1.5 cm high Views: 15
