HMNR28D(V)

5.0 or 3.3V, 16K bit (2 Kbit x 8) TIMEKEEPER NVSRAM

Part No. HMNR28D(V)

GENERAL DESCRIPTION

The HMNR28D(V) TIMEKEEPER SRAM is a 2Kb x 8 non-volatile static RAM and real time clock organized as 2,048

words by 8 bits. The special DIP package provides a fully integrated battery back-up memory and real time clock solution.

The HMNR28D(V) directly replaces industry standard 2Kbit x 8 SRAMs. It also provides the non-volatility of Flash without

any requirement for special WRITE timing or limitations on the number of WRITEs that can be performed.

FEATURES

■ INTEGRATED LOW POWER SRAM, REAL TIME CLOCK, POWER-FAIL CONTROL CIRCUIT, BATTERY and

CRYSTAL

■ BCD CODED YEAR, MONTH, DAY, DATE, HOURS, MINUTES, and SECONDS

■ AUTOMATIC POWER-FAIL CHIP DESELECT and WRITE PROTECTION VOLTAGES :

(V_PFD= Power-fail Deselect Voltage)

– HMNR28D : V_CC= 4.5 to 5.5V

4.2V ≤ V_PFD≤ 4.5V

– HMNR28DV: V_CC= 3.0 to 3.6V

2.7V ≤ V_PFD≤ 3.0V

■ CONVENTIONAL SRAM OPERATION : UNLIMITED WRITE CYCLES

■ SOFTWARE CONTROLLED CLOCK CALIBRATION FOR HIGH ACCURACY APPLICATIONS

■ 10 YEARS OF DATA RETENTION and CLOCK OPERATION IN THE ABSENCE OF POWER PIN and FUNCTION

COMPATIBLE WITH INDUSTRY STANDARD 2K x 8 SRAMS

■ SELF-CONTAINED BATTERY and CRYSTAL IN DIP PACKAGE
