On-Board Programming and Erasure
few exceptions. In User Boot mode and Single Boot mode (the RAM Transfer command), the flash memory
can be programmed and erased by the CPU executing software commands. It is the user’s responsibility to
create a program/erase routine. Because the flash memory can not be read while it is being programmed or
erased, the program/erase routine must be executed out of the on-chip RAM or an external memory device.
The TMP1940FDBF flash memory is command set compatible with the JEDEC EEPROM standard, with a

commands. For program/erase operations, the system can issue a command sequence to the flash
memory by using CPU instructions such as LD. After the 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.
from those of the standard flash command sequences. Unless otherwise noted, programming is done
word by word; thus the word load instruction should be used to write to the flash array. The byte load
instruction can be used to issue commands to the flash memory.

The TMP1940FDBF flash memory commands are in principle compatible with the standard JEDEC
Bear in mind that, due to the on-chip CPU interface, the TMP1940FDBF uses addresses different

Programs and verifies the desired addresses word by word 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.
