preliminary w49l201 publication release date: may 2000 - 3 - revision a1 functional descripti on read mode the read operation of the w49l201 is controlled by ce and oe , both of which have to be low for th e host to obtain data from the outputs. ce is used for device selection. when ce is high, the chip is de - selected and only standby power will be consumed. oe is the output control and is used to gate data to the output pins. the data bus is in high impedance state when either ce or oe is high. refer to the timing waveforms for further details. reset operation the reset input pin can be used in some applica tion. when reset pin is at high state, the device is in normal operation mode. when reset pin is driven low for at least a period of t rp , it will halts the device and all outputs are at high impedance state. the device al so resets the internal state machine to read array data. the operation that was interrupted should be reinitiated once the device is ready to accept another command sequence to assure data integrity. as the high state re - asserted to the reset pin, the device will return to read or standby mode, it depends on the control signals. the system can read data t rh after the reset pin returns to v ih . the other function for reset pin is temporary reset the boot blo ck. by applying the 12v to reset pin, the boot block can be reprogrammed even though the boot block lockout function is enabled. boot block operation there is one 8k - word boot block in this device, which can be used to store boot code. it is located in the first 8k words of the memory with the address range from 0000(hex) to 1fff(hex). see command codes for boot block lockout enable for the specific code. once this feature is set the data for the designated block cannot be erased or program med (programming lockout); other memory locations can be changed by the regular programming method. there is one condition that the lockout feature can be overrides. just apply 12v to reset pin, the lockout feature will temporary be inact ivated and the boot block can be erased/programmed. once the reset pin returns to ttl level, the lockout feature will be activated again. in order to detect whether the boot block feature is set on the 8k - words block, users can perform sof tware command sequence: enter the product identification mode (see command codes for identification/boot block lockout detection for specific code), and then read from address "0002 hex". if the output data in dq0 is "1", the boot block programming lockou t feature is activated; if the output data in dq0 is "0", the lockout feature is inactivated and the block can be erased/programmed. to return to normal operation, perform a three - byte command sequence (or an alternate single - word command) to exit the iden tification mode. for the specific code, see command codes for identification/boot block lockout detection. chip erase operation the chip - erase mode can be initiated by a six - word command sequence. after the command loading cycle, the device enters the int ernal chip erase mode, which is automatically timed and will be completed in a fast 100 ms (typical). the host system is not required to provide any control or timing
preliminary w49l201 - 4 - during this operation. the entire memory array will be erased to ff(hex) by the chip eras e operation if the boot block programming lockout feature is not activated. once the boot block lockout feature is activated, the chip erase function will erase all the sectors except the boot mode. sector erase operation the three sectors, main memory and two parameters blocks, can be erased individually by initiating a six - word command sequence. sector address is latched on the falling we edge of the sixth cycle while the 30(hex) data input command is latched at the rising edge of we. after the command lo ading cycle, the device enters the internal sector erase mode, which is automatically timed and will be completed in a fast 100 ms (typical). the host system is not required to provide any control or timing during this operation. the device will automatica lly return to normal read mode after the erase operation completed. data polling and/or toggle bits can be used to detect end of erase cycle. when the boot block lockout feature is inactivated, the boot block and the main memory block will be erased togeth er. once the boot block is locked, only the main memory block will be erased by the execution of sector erase operation. program operation the w49l201 is programmed on a word - by - word basis. program operation can only change logical data "1" to logical data "0" the erase operation (changed entire data in main memory and/or boot block from "0" to "1" is needed before programming. the program operation is initiated by a 4 - word command cycle (see command codes for word programming). the device will internally e nter the program operation immediately after the word - program command is entered. the internal program timer will automatically time - out (50 m s max. - t bc ) once completed and return to normal read mode. data polling and/or toggle bit s can be used to detect end of program cycle. hardware data protection the integrity of the data stored in the w49l201 is also hardware protected in the following ways: (1) noise/glitch protection: a we pulse of less than 15 ns in duration will not initiate a write cycle. (2) v dd power up/down detection: the programming operation is inhibited when v dd is less than 1.8v typical. (3) write inhibit mode: forcing oe low, ce high, or we high w ill inhibit the write operation. this prevents inadvertent writes during power - up or power - down periods. (4) v dd power - on delay: when v dd has reached its sense level, the device will automatically time - out 10 ms before any write (erase/program) operat ion. data polling (dq 7 ) - write status detection the w49l201 includes a data polling feature to indicate the end of a program or erase cycle. when the w49l201 is in the internal program or erase cycle, any attempt to read dq 7 of the last word loaded will r eceive the complement of the true data. once the program or erase cycle is completed, dq 7 will show the true data. note that dq 7 will show logical "0" during the erase cycle, and become logical "1" or true data when the erase cycle has been completed.
preliminary w49l201 publication release date: may 2000 - 5 - revision a1 to ggle bit (dq 6 ) - write status detection in addition to data polling, the w49l201 provides another method for determining the end of a program cycle. during the internal program or erase cycle, any consecutive attempts to read dq 6 will produce alternating 0' s and 1's. when the program or erase cycle is completed, this toggling between 0's and 1's will stop. the device is then ready for the next operation. product identification the product id operation outputs the manufacturer code and device code. programmin g equipment automatically matches the device with its proper erase and programming algorithms. the manufacturer and device codes can be accessed by software or hardware operation. in the software access mode, a six - word (or jedec 3 - word) command sequence c an be used to access the product id. a read from address 0000h outputs the manufacturer code, 00da(hex). a read from address 0001(hex) outputs the device code, 003e(hex). the product id operation can be terminated by a three - word command sequence or an alt ernative one - word command sequence (see command definition table). in the hardware access mode, access to the product id is activated by forcing ce and oe low, we high, and raising a9 to 12 volts. table of operating modes operating mode selection (v hh = 12v 0.5v) mode pins ce oe we reset address dq. read v il v il v ih v ih a in dout erase/program v il v ih v il v ih a i n din standby v ih x x v ih x high z erase/program x v il x v ih x high z/d out inhibit x x v ih v ih x high z/d out output disable x v ih x v ih x high z product id v il v il v ih v ih a0 = v il ; a9 = v hh ; other add = v il manufacturer code 00da (hex) v il v il v ih v ih a0 = v ih ; a9 = v hh; other add = v il ; device code 003e (hex) reset x x x v il x high z
