TMPM370FY
Product
Name
The TMPM370FY 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 TMPM370FY contains 64 words in a page.
Page writing requires 1.25ms (typical) regardless of number of words.
A block erase requires 0.1 sec. (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.
・The onboard programming mode
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.
(Note) The above values are theoretical values not including data transfer time.
• Automatic programming
• Automatic chip erase
• Automatic block erase
• Data polling/toggle bit
