The 44-pin, 330mil SOIC provides a battery pin for an external, user-supplied battery. This is all that is required to fully non-volatize the SRAM. Figure 1.

The control circuitry constantly monitors the single power supply for an out of tolerance condition. When VCC is out of tolerance, the circuit write protects the SRAM, providing a high degree of data security in the midst of unpredictable system operation brought on by low VCC. As VCC falls below approximately VSO, the control circuitry connects the battery which maintains data until valid power returns. Table 2.

The device architecture allows ripple-through access of data from eight of 262,144 locations in the static storage array. Thus, the unique address specified by the 15 Address Inputs defines which one of the 32,768 bytes of data is to be accessed. Valid data will be available at the Data I/O pins within Address Access time (tAVQV) after the last address input signal is stable, providing that the E and G access times are also satisfied. If the E and G access times are not met, valid data will be available after the latter of the Chip Enable Access time (tELQV) or Output Enable Access time (tGLQV). ro l o s ) s t( ) s t( E O ) s ( t c u d o r eP The state of the eight three-state Data I/O signals is controlled by E and G. If the outputs are activated before tAVQV, the data lines will be driven to an indeterminate state until tAVQV. If the Address Inputs are changed while E and G remain active, output data will remain valid for Output Data Hold time (tAXQX) but will go indeterminate until the next Address Access. t e ol s b O 7/19 Operating modes Figure 4.

The start of a WRITE is referenced from the latter occurring falling edge of W or E. A WRITE is terminated by the earlier rising edge of W or E. The addresses must be held valid throughout the cycle. E or W must return high for a minimum of tEHAX from Chip Enable or tWHAX from WRITE Enable prior to the initiation of another READ or WRITE cycle. Data-in must be valid tDVWH prior to the end of WRITE and remain valid for tWHDX afterward. G should be kept high during WRITE cycles to avoid bus contention; although, if the output bus has been activated by a low on E and G, a low on W will disable the outputs tWLQZ after W falls. 8/19 M48Z32V Operating modes Figure 5.

If E goes low simultaneously with W going low, the outputs remain in the high impedance state. d o r 2.3 O ) Data retention mode P e et l o s Ob Note: s ( t c u d With valid VCC applied, the M48Z32V operates as a conventional BYTEWIDE™ static RAM. Should the supply voltage decay, the RAM will automatically power-fail deselect, write protecting itself when VCC falls within the VPFD (max), VPFD (min) window. All outputs become high impedance, and all inputs are treated as “Don't care.” o r eP A power failure during a WRITE cycle may corrupt data at the currently addressed location, but does not jeopardize the rest of the RAM's content. At voltages below VPFD(min), the user can be assured the memory will be in a write protected state, provided the VCC fall time is not less than tF. The M48Z32V may respond to transient noise spikes on VCC that reach into the deselect window during the time the device is sampling VCC. Therefore, decoupling of the power supply lines is recommended. s b O t e ol When VCC drops below VSO, the control circuit switches power to the external battery which preserves data. As system power returns and VCC rises above VSO, the battery is disconnected, and the power supply is switched to external VCC. Write protection continues until VCC reaches VPFD(min) plus tREC(min). Normal RAM operation can resume tREC after VCC exceeds VPFD(max). For more information on Battery Storage Life refer to the Application Note AN1012. 10/19 M48Z32V 2.4 Operating modes VCC noise and negative going transients ICC transients, including those produced by output switching, can produce voltage fluctuations, resulting in spikes on the VCC bus. These transients can be reduced if capacitors are used to store energy which stabilizes the VCC bus. The energy stored in the bypass capacitors will be released as low going spikes are generated or energy will be absorbed when overshoots occur. A ceramic bypass capacitor value of 0.1µF (see Figure 7) is recommended in order to provide the needed filtering. In addition to transients that are caused by normal SRAM operation, power cycling can generate negative voltage spikes on VCC that drive it to values below VSS by as much as one volt. These negative spikes can cause data corruption in the SRAM while in battery backup mode. To protect from these voltage spikes, ST recommends connecting a schottky diode from VCC to VSS (cathode connected to VCC, anode to VSS). (Schottky diode 1N5817 is recommended for through hole and MBRS120T3 is recommended for surface mount). ) s t( Figure 7. c u d Supply voltage protection o r P VCC e t e VCC l o s 0.1μF ) s t( c u d ro P e et l o s Ob b O - c u d o r DEVICE P e et VSS l o bs ) s t( AI02169 O ) s ( t c u d o r eP t e ol s b O 11/19 Maximum rating 3 M48Z32V Maximum rating Stressing the device above the rating listed in the “Absolute Maximum Ratings” table may cause permanent damage to the device.
