STLED325

STLED325 I²C interfaced, advanced LED controller/driver with keyscan, standby power management and real time clock (RTC) Features ■ LED controller driver with 13 outputs (8 segments/5 digits) ■ Standby power management to host ■ Integrated low-power, accurate RTC ■ Integrated remote control decoding: – Philips (RC5, RCMM) – Thomson (RCA, R2000) – NEC and R-STEP ■ Wake-up using front panel keys, remote control, real time clock (RTC), extra pin (AV or CEC) ■ Battery or super-cap back up mode for real time clock (RTC) ■ Keyscanning (8x2 matrix) ■ Low power consumption in standby mode ■ I2C serial bus interface (SCL, SDA) ■ 16-step dimming circuit to control the display brightness ■ 5.0 V (± 10%) for VCC ■ Built-in thermal protection circuit ■ External crystal with internal oscillator for real time clock (RTC) Applications ■ Set-top boxes ■ White goods ■ Home appliances ■ DVD players, VCRs, DVD-R QFN32 (5 x 5 mm) Description The STLED325 is a compact LED controller/ driver that interfaces microprocessors to LED displays through serial I2C interface. It drives LEDs connected in common anode configuration and includes keyscanning for an 8 x 2 key matrix which automatically scans and de-bounces a matrix of up to 16 switches. Furthermore, the STLED325 provides standby power management to the host. It also integrates a low-power, highly-accurate RTC and a remotecontrol decoder. All functions are programmable using the I2C bus. Low power consumption during standby mode is achieved. T...
