Key Features
- SPI interface running at up to 3 MHz enables fast host access from any microcontroller with a standard SPI bus
- 1 Kb on-chip EEPROM and 64-byte SRAM provide non-volatile configuration storage and volatile scratchpad in a single device
- Operates from 1.8 V minimum supply, making it ideal for low-voltage, battery-powered and energy-harvesting designs
- Integrated unique ID memory simplifies device authentication and board serialization without external EEPROM
- Interrupt output pin enables event-driven wake-up of host MCU for ultra-low-power sleep-and-wake applications
Applications
The MCP79510T-I/MN is well-suited for IoT sensor nodes and data loggers that require accurate timekeeping with timestamped records stored in the built-in 64-byte SRAM between transmissions. Its 1.8 V minimum operating voltage and SPI interface make it a natural companion for low-power microcontrollers in wearable devices and remote wireless meters that rely on coin-cell batteries. The integrated EEPROM also allows the host system to store calibration constants or configuration flags alongside the real-time clock function.

Frequently Asked Questions
What communication interface does the MCP79510T-I/MN use, and at what maximum clock speed can the host access it?
The MCP79510T-I/MN uses a standard SPI serial interface with a maximum clock frequency of 3 MHz when operating from a 1.8 V supply, and faster speeds at higher voltages. This makes it directly compatible with virtually any microcontroller SPI peripheral without level-shifting in 3.3 V systems, simplifying firmware integration and reducing component count in battery-powered data-logger or IoT edge-node designs.
How much on-chip memory does the MCP79510T-I/MN provide, and what can each memory block be used for?
The device integrates 1 Kb of EEPROM for non-volatile storage of configuration data or calibration constants, 64 bytes of SRAM as a volatile scratchpad for temporary data between sleep cycles, and a factory-programmed unique ID block for board serialization. Together, these three memory types eliminate the need for external EEPROM or FRAM in applications that require lightweight data retention alongside a real-time clock function.
Which compact package does the MCP79510T-I/MN use, and how does it help space-constrained wearable designs?
The part is housed in a TDFN-10 (S-PDSO-N10) no-lead surface-mount package, which typically measures 3 mm x 3 mm with a very low profile under 1 mm. This footprint is ideal for wearable health monitors, smart badges, and miniature data loggers where PCB real estate is limited to a few square centimeters and height clearance must stay below 2 mm above the board surface.
Can the MCP79510T-I/MN operate reliably from a coin-cell battery, and what supply voltage range does it support?
Yes. The MCP79510T-I/MN operates from 1.8 V to 5.5 V, covering the full discharge curve of a CR2032 coin cell (3 V nominal, down to roughly 2 V at end of life). Its 32.768 kHz oscillator consumes only a few microamps in timekeeping mode, allowing years of battery-backed operation in remote sensing nodes, access-control tokens, and portable instruments that require continuous time tracking without a main power source.
