Search field Part name Part description. Program algorithm—an internal algorithm that auto. A 29f04 bit toggling between consecu- tive read cycles provides feedback to the user as to the status of the programming operation.

This can be achieved via programming equipment. The timing and verification of electrical erase are controlled internally within the device.

The device is fully. The Automatic Erase datashewt au- tomatically programs the entire array prior to electrical erase. After the state machine has completed its task, it will allow the command regis- ter to respond to its full command set. The 8 bits of. Kbytes each for flexible erase capability. Sector erase modes allow sectors of the array to be erased in one erase cycle. 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.


The device electrically erases all bits within a. MXIC’s Automatic Erase algorithm requires the user to write commands to the command register using stand- ard microprocessor write timings.

Am29FB has a second toggle bit, DQ2, and also. Device operations are selected by writing specific ad- dress and data 29f0400 into the command register.

A hardware method of locking sectors to prevent. The host system can detect whether a program or. The system can place the device into the standby.


Typical erasure at room temperature is accomplished in less than 4 second. In addition, the combination of advanced tunnel oxide processing and low internal electric fields for erase and programming operations produces reliable cycling.

The standard Am29FB offers access times of 55. Device erasure occurs by executing the erase com. The device is entirely command set compatible with the. During a Sector Erase cycle, the command register will only respond to Erase Suspend command.

The data is programmed using hot electron injec. The MXIC cell is designed to optimize the erase and program mechanisms. Table 1 defines the valid register command sequences. All sectors are 64 Kbytes in size. The typical chip programming time at room temperature of the MX29F is less than 4 seconds. The system should generate the following address patterns: This initiates the Embedded. A7 A6 A5 A4. MXIC’s Automatic Programming algorithm require the user to only write program set-up commands including 2 un- lock write cycle and A0H and a program command pro- gram data and address.

MXIC Flash technology reliably stores memory contents even aftererase and program cycles. During write cycles, the command register inter- nally latches address and data needed for the program- ming and erase operations.

The MX29F uses a 5. The highest degree of latch-up protection is achieved with MXIC’s proprietary non-epi process. A status bit similar 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.

Hardware data protection measures fatasheet a low. True background erase can thus be achieved.
