23 Flash Memory Operation
23.1
23.1.1
This section describes the hardware configuration and operation of the flash memory.
Flash Memory
TMPM380/382FW
Features
1) Memory capacity
2) Write/erase time
3) Programming method
The flash memory included in this device is generally compliant with the applicable JEDEC
standards except for some specific functions. Therefore, if the user is currently using an external
flash memory device, it is easy to implement the functions into this device. Furthermore, the
user is not required to build his/her own programs to realize complicated write and erase
functions because such functions are automatically performed using the circuits already built-in
the flash memory chip.
This device is also implemented with a read-protect function to inhibit reading flash memory
data from any external writer device. On the other hand, rewrite protection is available only
through command-based software programming; any hardware setting method to apply
+12VDC is not supported. See chapter 24 for details of ROM protection and security function.
Product Name
Rewriting method
TMPM380FY
TMPM382FS
The TMPM380/382 contains flash memory. The memory sizes and configurations are
shown in the table below. Independent write access to each block is available. When the
CPU is to access the internal flash memory, 32-bit data bus width is used.
Writing is executed per page. The TMPM380/382 contains 64 words in a page.
Page writing requires 1.25ms (typical) regardless of number of words.
A block erase requires 0.1 s. (typical).
The following table shows write and erase time per chip.
The write time per chip depends on the write method to be used by the user.
The onboard programming mode is available for the user to program (rewrite) the device
while it is mounted on the user's board.
