The AS1115 is capable of driving eight 7-segment digits at a current of 47 mA each and driving 64 individual LEDs at a current of 5 mA per LED. An external resistor makes it easy to adjust the current. The AS1115 has an excellent accuracy of ±3%, and the difference in intensity between the LEDs being driven and between the LED modules is extremely small, greatly improving the image quality of the LED display. Whether it is global digital brightness control or independent dimming of each digital, a 4-bit PWM mechanism is used. In addition, the AS1115 provides up to 16-key readback for a single-chip UI solution.
The Austrian Microelectronics AS1115 has a unique feature called built-in LED error detection. Using a simple, intuitive, user-friendly software interface makes error diagnosis easy to do during normal operation. The solution detects any open or short-circuit faults in a multiplexed 8x8 LED array, while providing detailed error reporting and reading the location of the damaged LED, which greatly reduces test time during production .
The AS1115 operates from a single 2.7V to 5.5V supply with a supply current of only 0.6mA during operation and 200nA in shutdown mode. The AS1115 is connected via an I2C bus, and up to four devices can be attached to one I2C bus.
The AS1115 is suitable for operating temperatures from -40 to 85 ° C and requires minimal external components to minimize system cost. For ease of processing, the AS1115 is available in a QSOP 24-pin package. TQFN (4x4)-24 packages are also available for space sensitive applications.
