The DS1642 is a 2K x 8 nonvolatile static RAM and a full-function real time clock which are both accessible in a bytewide format.
The nonvolatile time keeping RAM is pin- and function-equivalent to any JEDEC standard 2K x 8 SRAM.
The device can also be easily substituted in ROM, EPROM and EEPROM sockets, providing read/write nonvolatility and the addition of the real time clock function.
FEATURES● Integrated NV SRAM, real time clock, crystal, power fail control circuit and lithium energy source● Standard JEDEC bytewide 2K x 8 static RAM pinout● Clock registers are accessed identically to the static RAM.
These registers are resident in the eight top RAM locations● Totally nonvolatile with over 10 years of operation in the absence of power● Access times of 70 ns and 100 ns● Quartz accuracy ±1 minute a month @ 25°C, factory calibrated● BCD coded year, month, date, day, hours, minutes, and seconds with leap year compensation valid up to 2100● Power-fail write protection allows for ±10% VCC power supply tolerance● Lithium energy source is electrically disconnected to retain freshness until power is applied for the first time
Functional Equivalent (FE) materials, including Fused Filament Fabrication (FFF) form, assembly, and functionally compatible substitute materials.
