HMNR328D(V)

5.0 or 3.3V, 256K bit (32 Kbit x 8) TIMEKEEPER NVSRAM

HMNR328D(V)

Part No.

General Description

The HMNR328D(V) TIMEKEEPER SRAM is a 32Kb x 8 non-volatile static RAM and real time clock organized as 32,768

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

The HMNR328D(V) directly replaces industry standard 32Kbit 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)

– HMNR328D : V_CC= 4.5 to 5.5V

4.1V ≤ V_PFD≤ 4.5V

– HMNR328DV: 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

■ TYPICAL 5 YEARS OF DATA RETENTION and CLOCK OPERATION IN THE ABSENCE OF POWER PIN

■ SELF-CONTAINED BATTERY and CRYSTAL IN DIP PACKAGE
