white microelectronics ? phoenix, az ? (602) 437-1520 7 flash modules 3 wf128k16, wf256k16-xcx5 principles of operation write device erasure and programming are accomplished via the command register. the contents of the register serve as input to the internal state machine. the state machine outputs dictate the function of the device. the command register itself does not occupy an addressable memory location. the register is a latch used to store the commands, along with address and data information needed to execute the command. the command register is written by bringing write-enable to a logic-low level (v il ), while chip-select is low and oe is at v ih . addresses are latched on the falling edge of the write-enable while data is latched on the rising edge of the we pulse. standard microprocessor write timings are used. refer to ac program characteristics, figures 4 and 7. table 1 - bus operations operation cs oe we a 0 a 1 a 9 i/o read l l h a 0 a 1 a 9 d out standby h x x x x x high z output disable l h h x x x high z write l h l a 0 a 1 a 9 d in enable sector protect l v id l xxv id x verify sector protect l l h l h v id code the following principles of operation of the wf128k16-xcx5 and wf256k16-xcx5 are applicable to each 128k x 8 memory chip inside the mcm. programming of the device is accom- plished by executing the program command sequence. the program algorithm, which is an internal algorithm, automati- cally times the program pulse widths and verifies proper cell margin. sectors can be programmed and verified in less than 0.3 seconds. erase is accomplished by executing the erase command sequence. the erase algorithm, which is internal, automatically preprograms the array if it is not already programmed before executing the erase operation. during erase, the device automatically times the erase pulse widths and verifies proper cell margin. the entire memory is typically erased and verified in three seconds (including pre-program- ming). bus operations read the device has two control functions, both of which must be logically active, to obtain data at the outputs. chip-select (cs) is the power control and should be used for device selection. output-enable (oe) is the output control and should be used to gate data to the output pins. figure 3 illustrates read timing waveforms. output disable with output-enable at a logic-high level (v ih ), output from the device is disabled. output pins are placed in a high impedance state. standby mode the device has two standby modes, a cmos standby mode (cs input held at v cc + 0.5v), and a ttl standby mode (cs is held v ih ). in the standby mode the outputs are in a high impedance state, independent of the oe input. if the device is deselected during erasure or programming, the device will draw active current until the operation is completed.
