What are the key features of MCP79410T-I/MS?
- Integrated alarm, battery backup, and calendar functions eliminate external components for complete timekeeping in a single 8-pin MSOP package
- I2C serial interface (up to 100kHz at 1.8V) and 64 bytes of battery-backed SRAM enable data persistence across power cycles
- Low-power 32.768kHz oscillator operation with interrupt output provides accurate timekeeping and event triggering for microcontroller systems
What is MCP79410T-I/MS used for?
The MCP79410T-I/MS is designed for embedded systems requiring accurate timekeeping with calendar functionality, such as industrial data loggers, smart meters, medical monitoring devices, and consumer appliances with scheduling features. Its battery backup support ensures the clock continues running during main power interruptions, maintaining accurate time across power cycles. The 64-byte SRAM is useful for storing timestamps, configuration flags, or small data records that must survive power loss.

Frequently Asked Questions
What timekeeping functions does the MCP79410T-I/MS provide?
The MCP79410T-I/MS provides real-time clock (RTC) functions including time (hours, minutes, seconds), calendar (date, month, year), alarm generation, and battery backup support. It also includes 64 bytes of battery-backed SRAM for storing user data that persists through power interruptions.
What interface does the MCP79410T-I/MS use and at what speed?
The MCP79410T-I/MS uses an I2C serial interface with a maximum clock frequency of 100kHz (standard mode). It operates at a nominal voltage of 1.8V and is compatible with 3.3V and 5V systems through level-shifting, making it easy to integrate with a wide range of microcontrollers.
Does the MCP79410T-I/MS support alarms and interrupts?
Yes, the MCP79410T-I/MS includes alarm functionality with interrupt capability (Y). The alarm output can trigger a microcontroller interrupt to wake a system from sleep at a programmed time or date, enabling power-efficient scheduled operations in battery-powered embedded designs.
What package does the MCP79410T-I/MS use?
The MCP79410T-I/MS comes in an 8-pin MSOP (Mini Small Outline Package) with manufacturer code MSOP-8. This compact surface-mount package has a smaller footprint than standard SOIC-8, making it ideal for space-constrained PCB designs in portable and wearable applications.
