RS5C316B-E2-F

Real Time Clock Overview

The RS5C316B-E2-F is a CMOS Real-Time Clock (RTC) and calendar integrated circuit manufactured by Nisshinbo Micro Devices. It operates within a supply voltage range of 2.5V to 5.5V and functions reliably across an industrial temperature range of -40°C to +85°C. The device is housed in an 8-LSSOP package with dimensions of 3.0mm x 4.9mm x 1.1mm maximum height. It supports both parallel and serial interface options for timekeeping in HH:MM:SS format, accommodating 12-hour or 24-hour configurations.

Real Time Clock Feature Summary

• Integrated real-time clock and calendar functionality with leap year adjustment capabilities
• Supports dual interface modes including parallel data bus and serial communication protocols
• Features alarm function with interrupt output for system wake-up or event triggering

Real Time Clock Applications

• Portable electronic devices requiring precise timekeeping
• Industrial control systems needing calendar tracking
• Consumer appliances with scheduled operation features

Real Time Clock Procurement Notes

Verify the specific suffix designation against official datasheets to confirm interface configuration and package variant. Ensure compatibility with system voltage levels and temperature requirements before integration. Cross-reference part numbers with manufacturer documentation to avoid substitution errors involving different interface types or pinouts.

Real Time Clock Selection Notes

Select this component when both parallel and serial interface flexibility are required for RTC implementation. Consider the operating voltage range and temperature specifications relative to the target application environment. Evaluate space constraints against the LSSOP package dimensions and pin count limitations.

Real Time Clock Part Context

This part belongs to the RS5C series of real-time clocks from Nisshinbo Micro Devices, formerly RICOH. The series includes variants like the RS5C372A-E2-F which utilizes I2C interfaces. The RS5C316B-E2-F specifically offers parallel/serial versatility compared to purely serial alternatives in the product line.
