MCP79402-I/SN General Description

Boasting a built-in SRAM memory and a unique factory-programmed ID in EEPROM, the MCP79402-I/SN sets itself apart from other real-time clock/calendar devices. This locked section of EEPROM contains a MAC Address that can be unlocked and reprogrammed by the end user, adding a layer of customization to the device. With its low-cost 32,768 kHz crystal or other clock source, this RTCC provides reliable timekeeping in a compact and affordable package

Key Features

VCC Min = 1.8V
Icc < 5 µA Typical Dynamic Current
VBAT Min = 1.3V
Ibat < 700nA Typical Timekeeping & SRAM Retention Current
VCC to VBAT (power lost)
VBAT to VCC (power restored)
Dual alarms with single Interrupt Output that operates on VCC or VBAT
Clock Out frequencies of 32.768, 8.192 & 4.096 KHz and 1 Hz
1 ppm is approximately 86 milliseconds/day
Protect none, 1/4, 1/2 or all of array
Unique ID is factory programmed with MAC Address
