5 / 46 page  5 P/N:PM0549 REV. 1.3 , DEC. 24, 2001 MX29F200T/B AUTOMATIC ERASE ALGORITHM MXIC's Automatic Erase algorithm requires the user to write commands to the command register using stand- ard microprocessor write timings. The device will auto- matically pre-program and verify the entire array. Then the device automatically times the erase pulse width, verifies the erase and counts the number of sequences. A status bit toggling between consecutive read cycles provides feedback to the user as to the status of the programming operation. Register contents serve as inputs to an internal state- machine which controls the erase and programming circuitry. During write cycles, the command register internally latches addresses and data needed for the programming and erase operations. During a system write cycle, addresses are latched on the falling edge, and data are latched on the rising edge of WE . MXIC's Flash technology combines years of EPROM experience to produce the highest levels of quality, reliability, and cost effectiveness. The MX29F200T/B electrically erases all bits simultaneously using Fowler- Nordheim tunneling. The bytes are programmed by using the EPROM programming mechanism of hot electron injection. During a program cycle, the state-machine will control the program sequences and command register will not respond to any command set. During a Sector Erase cycle, the command register will only respond to Erase Suspend command. After Erase Suspend is complete, the device stays in read mode. After the state machine has completed its task, it will allow the command register to respond to its full command set. AUTOMATIC PROGRAMMING The MX29F200T/B is byte programmable using the Automatic Programming algorithm. The Automatic Pro- gramming algorithm does not require the system to time out sequence or verify the data programmed. The typical chip programming time of the MX29F200T/B at room temperature is less than 2 seconds. AUTOMATIC CHIP ERASE The entire chip is bulk erased using 10 ms erase pulses according to MXIC's Automatic Chip Erase algorithm. Typical erasure at room temperature is accomplished in less than two second. The Automatic Erase algorithm automatically programs the entire array prior to electrical erase. The timing and verification of electrical erase are internally controlled by the device. AUTOMATIC SECTOR ERASE The MX29F200T/B is sector(s) erasable using MXIC's Auto Sector Erase algorithm. Sector erase modes allow sectors of the array to be erased in one erase cycle. The Automatic Sector Erase algorithm automatically pro- grams the specified sector(s) prior to electrical erase. The timing and verification of electrical erase are inter- nally controlled by the device. AUTOMATIC PROGRAMMING ALGORITHM MXIC's Automatic Programming algorithm requires the user to only write program set-up commands (include 2 unlock write cycle and A0H) and a program command (program data and address). The device automatically times the programming pulse width, verifies the pro- gram, and counts the number of sequences. A status bit similar to DATA polling and a status bit toggling between consecutive read cycles, provides feedback to the user as to the status of the programming operation. |
