Matching phases while E2PROM accessed
S-24CS01A/02A/04A/08A does have resetting (the internal circuit), therefore, E2PROM cannot forcibly reset externally. communication interruption occurs E2PROM, must reset software. example, even reset signal input microprocessor, internal circuit E2PROM reset long stop condition input E2PROM. other words, E2PROM retains same status cannot shift next operation. This symptom applies case when only microprocessor reset when power supply voltage drops. With this status, power supply voltage restored, reset E2PROM (after matching phase with microprocessor) input instruction. following shows this reset method.
[How reset E2PROM]
E2PROM reset start stop instructions. When E2PROM reading data outputting acknowledge signal, output line. this status, microprocessor cannot output instruction line. this case, terminate acknowledge output operation read operation, then input start instruction. Figure shows this procedure. First, input start condition. Then transmit clocks (dummy clocks) SCL. During this time, microprocessor sets line high level. this operation, E2PROM interrupts acknowledge output operation data output, input start condition*1. When start condition input, E2PROM reset. make doubly sure, input stop condition E2PROM. Normal operation then possible.

Trap: E2PROM operation case that stop condition received during write operation before receiving defined data value (less than 8-bit)
When E2PROM receives stop condition signal compulsorily, during receiving byte write data, "write" operation aborted. When E2PROM receives stop condition signal after receiving byte more data "page write", 8-bit data received normally before receiving stop condition signal written.
Trap: E2PROM operation write data case that write data input more than defined page size "page write"
When write data input more than defined page size page write operation, example, S-24CS04A (which executed 16-byte page write) received data more than byte, 8-bit data 17th byte over written first byte same page. Data over capacity page address cannot written.
Trap: Severe environments
Absolute maximum ratings: operate these excess absolute maximum ratings listed data sheet). Exceeding supply voltage rating cause latch-up. Operations with moisture E2PROM pins occur malfunction short-circuit between pins. Especially, occasions like picking E2PROM from temperature tank during evaluation. sure that remain frost E2PROM prevent malfunction short-circuit.
