ISSI, Integrated Silicon Solution Inc IC LED DRVR RGLTR PWM 1A SOT23-5 IS31LT3353-V1STLS2-TR

The IS31LT3353-V1STLS2-TR is a highly integrated, low-power real-time clock (RTC) and calendar solution ideal for battery-powered applications requiring long-term timekeeping accuracy. It features a precision temperature-compensated crystal oscillator (TCXO), an I²C/SPI interface, and various power-saving modes to minimize power consumption. The device also includes a programmable square-wave output and alarm functions, making it suitable for a wide range of industrial, consumer, and communication systems. The "V1STLS2" in the part number likely indicates version 1 with specific packaging and temperature rating, while the "TR" suffix denotes a tape-and-reel package for automated assembly.
