... See Table 7 for details. Figure 3. Block Diagram LITHIUM CELL VOLTAGE SENSE The M48Z35/35Y is a non-volatile pin and function equivalent to any JEDEC standard 32K x8 SRAM. It also easily fits into many ROM, EPROM, and EEPROM sockets, providing the non-volatility of PROMs without any requirement for special write timing or limitations on the number of writes that can be performed ...

... M48Z35, M48Z35Y POWER SUPPLY DECOUPLING and UNDERSHOOT PROTECTION I transients, including those produced by output CC switching, can produce voltage fluctuations, re- sulting in spikes on the V bus. These transients CC can be reduced if capacitors are used to store en- ergy, which stabilizes the V CC stored in the bypass capacitors will be released as low going spikes are generated or energy will be absorbed when overshoots occur ...
