M41T00S General Description

The M41T00S Serial Access TIMEKEEPER^® SRAM is a low power Serial RTC with a built-in 32.768kHz oscillator (external crystal controlled). Eight bytes of the SRAM (see Table 2., page 11) are used for the clock/calendar function and are configured in binary coded decimal (BCD) format. Addresses and data are transferred serially via a two line, bi-directional I2C interface. The built-in address register is incremented automatically after each WRITE or READ data byte.

The M41T00S has a built-in power sense circuit which detects power failures and automaticallyswitches to the battery supply when a power failure occurs. The energy needed to sustain the clock operations can be supplied by a small lithium button supply when a power failure occurs. The eight clock address locations contain the century, year, month, date, day, hour, minute, and second in 24 hour BCD format. Corrections for 28, 29 (leap year - valid until year 2100), 30 and 31 day months are made automatically.

The M41T00S is supplied in an 8-pin SOIC.

M41T00S Maximum Ratings

Symbol	Parameter		Value	Unit
T_STG	Storage Temperature (V_CC Off, Oscillator Off)	SOIC	55 to 125
V_CC	Supply Voltage		0.3 to 7	V
T_SLD	Lead Solder Temperature for 10 Seconds	Lead-free lead finish⁽¹⁾	260
T_SLD	Lead Solder Temperature for 10 Seconds	Standard (SnPb) lead finish^(2,3)	240
V_IO	Input or Output Voltages		-0.3 to V_CC + 0.3	V
I_O	Output Current		20	mA
P_D	Power Dissipation		1	W

Note: 1. For SO8 package, Lead-free (Pb-free) lead finish: Reflow at peak temperature of 260°C (total thermal budget not to exceed 245°C for greater than 30 seconds).
2. For SO8 package, standard (SnPb) lead finish: Reflow at peak temperature of 240°C (total thermal budget not to exceed 180°C for between 90 to 150 seconds).
3. The SOX18 package has Lead-free (Pb-free) lead finish, but cannot be exposed to peak reflow temperature in excess of 240°C (use same reflow profile as standard (SnPb) lead finish).
CAUTION: Negative undershoots below 0.3 volts are not allowed on any pin while in the Battery Back-up Mode
