MAX6954 Détails du produit

General Description

The MAX6954 is a compact display driver that interfaces microprocessors to a mix of 7-segment, 14-segment, and 16-segment LED displays through an SPI™- or QSPI™-compatible 4-wire serial interface. The serial interface may be cascaded through multiple devices. 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 (or GPIO) 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.



Features

♦ High-Speed 26MHz SPI/QSPI/MICROWIRE™-Compatible Serial Interface

♦ 2.7V to 5.5V Operation

♦ Drives Up to 16 Digits 7-Segment, 8 Digits 14-Segment, 8 Digits 16-Segment, 128 Discrete LEDs, or a Combination of Digit Types

♦ Drives Common-Cathode Monocolor and Bicolor LED Displays

♦ Built-In ASCII 104-Character Font for 14-Segment and 16-Segment Digits and Hexadecimal Font for 7-Segment Digits

♦ Automatic Blinking Control for each Segment

♦ 10µA (typ) Low-Power Shutdown (Data Retained)

♦ 16-Step Digit-by-Digit Digital Brightness Control

♦ Display Blanked on Power-Up

♦ Slew-Rate Limited Segment Drivers for Lower EMI

♦ Five GPIO Port Pins Can Be Configured as Key Switch Reader to Scan and Debounce Up to 32 Switches with n-Key Rollover

♦ IRQ Output when a Key Input Is Debounced

♦ 36-Pin SSOP and 40-Pin DIP and TQFN Packages

♦ Automotive Temperature Range Standard
