PRELIMINARY

DS1747/DS1747P

Y2KC Nonvolatile Timekeeping RAM

www.dalsemi.com

FEATURES

Integrated NV SRAM, real time clock,

crystal, power-fail control circuit and lithium

energy source

Clock registers are accessed identical to the

static RAM. These registers are resident in the

eight top RAM locations.

Century byte register; ie., Y2K compliant

Totally nonvolatile with over 10 years of

operation in the absence of power

BCD coded century, year, month, date, day,

hours, minutes, and seconds with automatic

leap year compensation valid up to the year

2100

Battery voltage level indicator flag

Power-fail write protection allows for ±10%

power supply tolerance

Lithium energy source is electrically

disconnected to retain freshness until power is

applied for the first time

DIP Module only

- Standard JEDEC Byte-wide 512k x 8

static RAM pinout

PowerCap Module Board only

- Surface mountable package for direct

connection to PowerCap containing

battery and crystal

- Replaceable battery (PowerCap)

- Power-On Reset Output

- Pin for pin compatible with other densities

of DS174XP Timekeeping RAM
