The Automatic Erase algorithm au- tomatically programs the entire array prior to electrical erase.

The MX29F uses a 5. The sector erase architecture allows memory sectors. Program algorithm—an internal algorithm that auto. The Automatic Program- ming algorithm makes dwtasheet external system do not need to have time out sequence nor to verify the data pro- grammed. The highest degree of latch-up protection is achieved with MXIC’s proprietary non-epi process. After Erase Suspend is completed, the device stays in read mode. Table 1 defines the valid register command sequences. The 8 bits of.

During write cycles, the command register inter- nally latches address and data needed for the program- ming and erase operations.

C2H 29f00 manufacture code, A4H for device code. In addition, the combination of advanced tunnel oxide processing and low internal electric fields for erase and programming operations produces reliable cycling. The MXIC cell is designed to optimize the erase and program mechanisms. A status bit toggling between consecu- tive read cycles provides feedback to the user as to the status of the programming operation.


The device will auto- matically pre-program and verify the entire array.

MXIC’s Automatic Erase algorithm requires the user to write commands to the datasheef register using stand- ard microprocessor write timings. This initiates the Embedded. The timing and verification of electrical erase are controlled internally within the device. Sector erase modes allow sectors of the array to be erased in one erase cycle. A18 A16 A15 A Device operations are selected by writing specific ad- dress and data sequences into the command register.

Device erasure occurs by executing the erase com. The MX29F uses a datashedt register to manage this functionality.

The system can place the device into the standby. The standard MX29F offers access time as fast as 55ns, allowing operation of high-speed microprocessors without wait states.

The typical chip programming time at room temperature of the MX29F is less than 4 seconds. All sectors are 64 Kbytes in size. If read out data is 01H, it means the sector has been protected. Kbytes each for flexible erase capability. The Am29FB is a 4 Mbit, 5.

During a system write cycle, addresses are latched on the falling edge of WE or CE, whichever happens later, and data are latched on the rising edge of WE or CE, whichever happens first.

Writing incorrect address and data values or writing them in the improper sequence will reset the device to the read mode. The Erase Suspend feature enables the user to put.


The device automatically times the programming pulse width, provides the program veri- fication, and counts the number of sequences. Power consumption is greatly reduced in. A status bit 29t040 to DATA polling and a status bit toggling be- tween consecutive read cycles, provide feedback to the user as to the status of the programming operation. Am29FB has a second toggle bit, DQ2, and also.

Register contents serve as inputs to an internal state- machine which controls the erase and programming cir- cuitry. Search field Part name Part description. The data is programmed using datasheef electron injec. This can be achieved via programming equipment. Typical erasure at room temperature is accomplished in less than 4 second.

This initiates the Embedded Erase.

The device is entirely command set compatible with the. For Sector Protect Verify Operation: The host system can detect whether a program or. Device programming occurs by executing the program. After the state machine has completed datashheet task, it will allow the command regis- ter to respond to its full command set.

The device requires only a single 5.

True background erase can thus be achieved. The device electrically erases all bits within a. During a program cycle, the state-machine will control the program sequences 299f040 command register will not respond to any command set.
