HMNR5128D(V)

5.0 or 3.3V, 4 Mbit (512 Kbit x 8) TIMEKEEPER NVSRAM

Part No. HMNR5128D(V)

General Description

The HMNR5128D(V) TIMEKEEPER SRAM is a 512Kb x 8 non-volatile static RAM and real time clock organized as

524,280 words by 8 bits. The special DIP package provides a fully integrated battery back-up memory and real time clock

solution. The HMNR5128D(V) directly replaces industry standard 512Kbit 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)

– HMNR5128D : V_CC= 4.5 to 5.5V

4.1V ≤ V_PFD≤ 4.5V

– HMNR5128DV: 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

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

COMPATIBLE WITH INDUSTRY STANDARD 512K x 8 SRAMS

■ SELF-CONTAINED BATTERY and CRYSTAL IN DIP PACKAGE
