IC RTC CLK/CALENDAR PAR 32-DIP
The DS1386-32-120+ is a 32-Kbit Serial Real-Time Clock/SRAM (RTCSRAM) device from Maxim Integrated. It combines a real-time clock, a 32-Kbit SRAM, and a power-fail detect circuit in a single package. The device features a low-power CMOS design and is available in a DIP-32 package. It is designed to provide a low-power, low-cost solution for applications requiring real-time clock and SRAM functions. The device is ideal for applications such as industrial control, medical, and consumer applications. The DS1386-32-120+ features a real-time clock with a programmable alarm, a 32-Kbit SRAM, and a power-fail detect circuit. The real-time clock provides time-of-day information and includes a programmable alarm that can be used to generate an interrupt. The 32-Kbit SRAM provides non-volatile storage of data and is accessible via an I2C interface. The power-fail detect circuit monitors the VCC supply and generates an interrupt when the supply voltage drops below a certain threshold. The DS1386-32-120+ is designed to operate over a wide temperature range (-40°C to +85°C) and is available in a DIP-32 package. It is RoHS compliant and is available in both commercial and industrial temperature ranges. (For reference only)
