commands. After a command sequence is written, the flash memory does not require the system to
provide further controls or timings. The flash memory initiates the embedded program or erase
algorithm automatically. The entire flash memory or one or more flash blocks can be erased at a time.
commands. Unless otherwise noted, the subsections that follow indicate addresses as seen from the
programmer.
Programmer mode, with a few exceptions such as the data bus width. Refer to Section 3.6 for a
description of the program and erase operations in on-board programming modes.
The TMP1940FDBF flash memory commands are in principle compatible with the standard JEDEC
All accesses to the flash memory are performed halfword by halfword, including the writing of
The program/erase operations of on-board programming modes are very similar to those of
Programs and verifies the desired addressed halfword by halfword automatically.
Erases and verifies the entire memory array automatically.
Erases and verifies all memory locations in the selected block automatically.
Erases and verifies all memory locations in multiple selected blocks automatically.
Provides several status bits such as the Data Polling bit, which can be used to determine whether a
program or erase operation is complete or in progress.
Prevents intrusive access to the flash memory while in Programmer mode. When the security
feature is turned off, the entire memory array is erased and verified automatically, regardless of
whether a given block is protected or not.
Disables both program and erase operations in any block.
