NOTES:
1. All voltages are referenced to ground.
2. Maximum operating I
CC
is measured with all output pins disconnected; XTAL1 driven with t
CLKR
,

CLKF
= 10 ns, V
IL
= 0.5V; XTAL2 disconnected; EA = RST = PORT0 = V

3. Idle mode I
CC
is measured with all output pins disconnected; XTAL1 driven at 8 MHz with t

5. Crystal start-up time is the time required to get the mass of the crystal into vibrational motion from
the time that power is first applied to the circuit until the first clock pulse is produced by the on-chip
oscillator. The user should check with the crystal vendor for the worst-case spec on this time.
NORMAL OPERATION IS MEASURED USING:
1) EXTERNAL CRYSTALS ON XTAL1 AND 2.
2) ALL PORT PINS DISCONNECTED.
3) RST = 0V AND EA = V
CC
.
4) PART PERFORMING ENDLESS LOOP WRITING TO INTERNAL
MEMORY.
IDLE MODE OPERATION IS MEASURED USING:
1) EXTERNAL CLOCK SOURCE AT XTAL1; XTAL2 FLOATING.
2) ALL PORT PINS DISCONNECTED.
3) RST = 0V AND EA = V
CC
.
4) PART SET IN IDLE MODE BY SOFTWARE.

DATA SHEET REVISION SUMMARY
The following represent the key differences between 12/13/95 and 08/16/96 version of the DS2250(T)
data sheet. Please review this summary carefully.
1. Correct Figure 3 to show RST active high.
2. Add minimum value to PCB thickness.
The following represent the key differences between 11/20/99 and 06/09/06 version of the DS2250(T)
data sheet. Please review this summary carefully.
1. Updated reference (Features) to 10-year NV RAM data life to include room temperature caveat.
2. Added lead-free package information to the Ordering Information table.
3. Removed 8kB package versions from Ordering Information table.
4. Removed references to “Secure Microcontroller Data Book” and changed them to “Secure
Microcontroller User’s Guide.”
5. Removed references to DS5000TK.
