DS1244Y-70+ Real Time Clock RTC IC Rizees 32KB Parallel 28-DIP 0.600in

Description

Product Overview

The DS1244Y-70+ Real Time Clock (RTC) Integrated Circuit from Rizees is engineered for high‑precision timing in demanding industrial environments. Featuring a 32KB parallel non‑volatile SRAM (NVSRAM) that retains data without power, the device supports automatic leap‑year correction, ensuring calendar accuracy over long periods. Operating voltage ranges from 4.5V to 5.5V, and the chip consumes a maximum of 10 mA during timekeeping, which helps extend battery life in remote applications. The module is housed in a compact 28‑pin DIP package measuring 0.600 inches (15.24 mm), making it easy to mount on standard printed circuit boards.

Key specifications include a time format of HH:MM:SS:hh with selectable 12‑hour or 24‑hour mode, temperature operating range from 0 °C to 70 °C, and robust protection against voltage spikes. The device’s parallel interface allows rapid data access, simplifying integration with microcontrollers and FPGA designs. Its low standby current and reliable oscillator circuit make it a preferred choice for data loggers, PLCs, and other timing‑critical systems.

Usage

Designed for a wide variety of industrial and scientific applications, the DS1244Y-70+ excels in environments where accurate time stamping is essential. Typical use cases include monitoring and logging equipment in manufacturing plants, synchronizing processes in automation systems, and providing time reference for communication modules in IoT devices. The chip’s ability to retain time data during power interruptions ensures that critical operations resume without loss of schedule integrity.

Engineers can integrate the RTC into embedded systems that require precise scheduling, such as motor control units, environmental monitoring stations, and remote telemetry units. Its compact DIP form factor fits comfortably on dense board layouts, while the parallel data bus reduces latency for time‑critical reads and writes. The device also supports battery backup, allowing continuous operation even when the main power source is disconnected.
