MCP79512T-I/MS

Real Time Clock Overview

The MCP79512T-I/MS is a calendar real-time clock (RTC) manufactured by Microchip Technology, belonging to the MCP795 series. It features an SPI interface and is housed in a 10-pin MSOP package. The device operates within a supply voltage range of 1.8 V to 3.6 V and supports an industrial temperature range from -40°C to +85°C. Internal memory includes 64 bits of SRAM. The RTC provides date formatting in DW:M:Y:LY structure.

Real Time Clock Feature Summary

• Calendar Real-Time Clock with SPI interface
• 1.8 V to 3.6 V operating voltage range
• Industrial temperature range (-40°C to +85°C)
• 64-bit SRAM storage capacity

Real Time Clock Applications

• General purpose timekeeping in embedded systems
• Data logging applications requiring accurate timestamps
• Consumer electronics with low power requirements

Real Time Clock Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging when ordering. Confirm the 'I' designation corresponds to the industrial temperature grade. Ensure the MSOP-10 package dimensions match the target PCB footprint. Cross-reference the full part number with official Microchip documentation to confirm current production status and availability.

Real Time Clock Selection Notes

Select this component for designs requiring a compact SPI-based RTC with integrated calendar functions. The 1.8 V to 3.6 V voltage range suits low-power microcontroller systems. Compare against the broader MCP795 family if additional memory or different interface options are needed. Verify that the 64-bit SRAM meets the data storage requirements for the specific application.

Real Time Clock Part Context

This part belongs to the Microchip MCP795 series of compact, 10-pin real-time clocks. These devices provide accurate timekeeping over a wide temperature range. The MCP79512 variant specifically offers SPI connectivity and basic calendar functionality, distinguishing it from I2C-based models or those with larger EEPROM capacities in the same family.

Real Time Clock Replacement Considerations

Direct substitutes within the MCP795 series include other SPI-enabled variants such as the MCP79511 or MCP79513, provided pin compatibility and memory sizes align with design constraints. Verify package equivalence for MSOP-10 replacements.
