... Low Power Consumption - Low active read current: 10mA (typical) at 5MHz GENERAL DESCRIPTION The MX29LV033 is a 32-mega bit Flash memory orga- nized as 4M bytes of 8 bits. MXIC's Flash memories offer the most cost-effective and reliable read/write non- volatile random access memory. The MX29LV033 is packaged in 40-pin TSOP ...
Page 2
... The MX29LV033 uses a 2.7V to 3.6V VCC supply to perform the High Reliability Erase and auto Program/Erase algorithms. The highest degree of latch-up protection is achieved with MXIC's proprietary non-epi process. Latch-up protection is proved for stresses up to 100 milliamps on address and data pin from -1V to VCC + 1V ...

... HH accelerated programming, or device damage may result. STANDBY MODE MX29LV033 can be set into Standby mode with two dif- ferent approaches. One is using both CE and RESET pins and the other one is using RESET pin only. When using both pins of CE and RESET, a CMOS Standby mode is achieved with both pins held at Vcc ± ...

... OE input. MX29LV033 is capable to provide the Automatic Standby Mode to restrain power consumption during read-out of data. This mode can be used effectively with an applica- tion requested low power consumption such as handy terminals. To active this mode, MX29LV033 automatically switch themselves to low power mode when MX29LV033 ad- dresses remain stable during access time of tACC+30ns ...

Which method requires VID on A9 pin, VIH on WE and A1 pins, VIL on CE, OE, A6, and A0 pins, and sector address on A16 to A21 pins. Which the identified sector is protected, the device will output 01H ...

... Writing is inhibited by holding any one VIL VIH VIH. To initiate a write cycle CE and WE must be a logical zero while logical one. POWER-UP SEQUENCE The MX29LV033 powers up in the Read only mode. In addition, the memory contents may only be altered after successful completion of the predefined command se- quences. ...

... The reset command may be written between the sequence cycles in an erase command sequence before P/N:PM0679 MX29LV033 erasing begins. This resets the device to reading array data. Once erasure begins, however, the device ignores reset commands until the operation is complete. ...
Page 14
... However, a succeeding read will show that the data is still "0". Only erase operations can convert a "0" "1". P/N:PM0679 MX29LV033 UNLOCK BYPASS COMMAND SEQUENCE The unlock bypass feature allows the system to pro- gram bytes to the device faster than using the standard program command sequence ...

... See the Erase/Program Operations tables in "AC Char- acteristics" for parameters, and to Figure 16 for timing diagrams. P/N:PM0679 The MX29LV033 contains a Silicon-ID-Read operation to supplement traditional PROM programming method- ology. The operation is initiated by writing the read sili- con ID command sequence into the command register. ...

... Q5 will produce a "1". This time-out condition indicates that the program or erase cycle was not suc- cessfully completed. Data Polling and Toggle Bit are the P/N:PM0679 MX29LV033 only operating functions of the device under this condi- tion. If this time-out condition occurs during sector erase op- eration, it specifies that a particular sector is bad and it may not be reused ...
