Introduction

AI Translation

The AS1115 is a compact LED driver for 64 single LEDs or 8 digits of 7 - segments. The devices can be programmed via an I²C compatible 2 - wire interface. Every segment can be individually addressed and updated separately. Only one external resistor (RSET) is required to set the current. LED brightness can be controlled by analog or digital means. The devices include an integrated BCD code - B/HEX decoder, multiplex scan circuitry, segment and display drivers, and a 64 - bit memory. Internal memory stores the shift register settings, eliminating the need for continuous device reprogramming. All outputs of the AS1115 can be configured for key readback. Keyswitch status is obtained by polling for up to 64 keys while 16 keys can be used to trigger an interrupt. Additionally the AS1115 offers a diagnostic mode for easy and fast production testing. The AS1115 features a low shutdown current of typically 200nA, and an operational current of typically 350μA. The number of digits can be programmed, the devices can be reset by software, and an external clock is also supported. The device is available in a QSOP - 24 and the TQFN(4x4) - 24 package.
