Драйвер дисплея, ЖКД 16 знаков, 7 сегментов, 2.7В до 5.5В питание, SPI интерфейс, TQFN-40

The MAX6954ATL+ from Maxim Integrated Products is a 4-wire interfaced, 2.7V to 5.5V LED display driver with I/O expander and key scan in 40 pin TQFN package. It is a compact display driver that interfaces microprocessors to a mix of 7-segment, 14-segment and 16-segment LED displays. The MAX6954 drives up to 16 digits 7-segment, 8 digits 14-segment, 8 digits 16-segment or 128 discrete LEDs while functioning from a supply voltage as low as 2.7V. The driver includes five I/O expander lines, some or all of which may be configured as a key switch reader which automatically scans and debounces a matrix of up to 32 switches. Included on chip are full 14 and 16-segment ASCII 104-character fonts, a hexadecimal font for 7-segment displays, multiplex scan circuitry, anode and cathode drivers and static RAM that stores each digit. Typical applications include set-top boxes, panel meters, white goods, bar graph displays and audio/video equipments.
