AT89C51ED2-RLTIM General Description

One of the standout features of the AT89C51ED2-RLTIM is its integrated real-time clock and timer (RLTIM) module. This module provides precise timing and scheduling capabilities for time-sensitive applications, offering a programmable clock with a resolution of 1ms and the ability to trigger interrupts at specific time intervals. This makes it an ideal choice for applications that require accurate timekeeping and scheduling
