SANYO assumes no responsibility for equipment failures that result from using products at values that exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or other parameters) listed in products specifications of any and all SANYO products described or contained herein.
A block erase operation erases one of the devices 32 k-word blocks typically within 0.39 second (5 V VCC, 12 V VPP), 4 k-word blocks typically within 0.25 second (5 V VCC, 12 V VPP) independent of other blocks. Each block can be independently erased 100 000 times. Block erase suspend mode allows system software to suspend block erase to read data from, or write data to any other block.
The topping charge is applied for a minimum of two (2) hours. The current consists of the same pulse technique used during the fast charge stage; however, the delay time is extended as shown in Figure 5. Extending the delay time between charge pulses allows the same charging current used as in the fast charge stage so that no changes to the current source are necessary. For example, the same charge pulse that occurs every second at a 1C (1 hour) fast charge rate will occur every eleven (11) seconds for a topping charge rate of C/11. The MMN indicator is a continuous active low during the topping and maintenance charge stages.
