... Each is capable of sequential read, at which time addresses are automatically incremented in 16-bit blocks. The instruction code is compatible with the NM93CSXX Series. The S-29XX1A Series is capable of protecting the memory, 50% of which can be protected starting from address 00. 5 Endurance : 10 ...

... SK after CS goes high. A start-bit can only be recognized when the high latched to the rising edge of SK when CS goes from low to high impossible for recognized as long low, even if there are SK pulses after CS goes high. Any SK pulses input while DI is low are called "dummy clocks." Dummy clocks can be used to adjust the number of clock cycles needed by the serial IC to match those sent out by the CPU ...

... Series easy to VERIFY the completion of the write operation in order to minimize the write cycle by setting CS to high and checking the DO pin, which is low during the write operation and high after its completion. This VERIFY procedure can be executed over and over again. ...

... After changing CS to high, input a start-bit, op-code (WRITE), address, and 16-bit data. If there is a data overflow of more than 16 bits, only the last 16-bits of the data is considered valid. Changing CS to low will start the WRITE operation not necessary to make the data "1" before initiating the WRITE operation. ...

... This command erases 16-bit data in a specified address. After changing CS to high, input a start-bit, op-code (ERASE), and address not necessary to input data. Changing CS to low will start the ERASE operation, which changes every bit of the 16 bit data to "1." ...

If there is a data overflow of more than 16 bits, only the last 16-bits of the data is considered valid. Changing CS to low will start the WRAL operation not necessary to make the data "1" before initiating the WRAL operation. ...

... Write enable (EWEN) and Write disable (EWDS) The EWEN instruction puts the S-29XX1A Series into write enable mode, which accepts WRITE, ERASE, WRAL, and ERAL instructions. The EWDS instruction puts the S-29XX1A Series into write disable mode, which refuses WRITE, ERASE, WRAL, and ERAL instructions. ...

... Both the recognition of a start-bit and the VERIFY procedure occur when CS is “high.” Therefore, only after a write operation, in order to accept the next command by having CS go high, will the DO pin switch from a state of high- impedence to a state of data output; but if it recognizes a start-bit, the DO pin returns to a state of high-impedence. ...
