ISL1209IU10-TK

Real Time Clock Overview

The ISL1209IU10-TK is a Real-Time Clock (RTC) integrated circuit manufactured by Renesas Electronics Corporation. It features an I2C serial bus interface and supports date formats of YY-MM-DD-dd and time formats of HH:MM:SS in 24-hour mode. The device operates within a supply voltage range of 2.7 V to 5.5 V and includes backup switching capabilities for continuous operation during power loss. It is housed in a 10-lead MSOP package and functions reliably across an industrial temperature range from -40°C to +85°C.

Real Time Clock Procurement Notes

Verify the specific suffix 'TK' against official Renesas documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with system voltage levels between 2.7 V and 5.5 V. Confirm moisture sensitivity level requirements for surface mount assembly processes.

Real Time Clock Selection Notes

Select this component when a compact RTC with I2C connectivity and low-power backup switching is required. The MSOP-10 package suits space-constrained designs. Verify that the 2-byte SRAM storage capacity meets application data retention needs.

Real Time Clock Part Context

This part belongs to the ISL1209 series of real-time clocks. The series offers various package options including SOIC and TSSOP, with differing SRAM capacities. The ISL1209 variant specifically provides 2 bytes of general-purpose RAM alongside clock/calendar functionality.

Real Time Clock Replacement Considerations

Consult official cross-reference lists for direct substitutes. Other members of the ISL1209 family may offer different pinouts or memory sizes.
