Flash Memory
TMP1940FDBF contains a 512-Kbyte flash EEPROM and 16-Kbyte RAM whereas the TMP1940CYAF
contains a 256-Kbyte ROM and a 10-Kbyte RAM. In other respects, the hardware configuration and the
functionality of the TMP1940FDBF are identical to those of the TMP1940CYAF. For descriptions of the on-
chip I/O peripherals, refer to the TMP1940CYAF datasheet.
This chapter describes the flash memory of the TMP1940FDBF, a flash version of the TMP1940CYAF. The

The TMP1940FDBF contains 4 Mbits (512 Kbytes) of flash memory, which is divided into a total of 19
blocks (fifteen 32-Kbyte, one 16-Kbyte, one 8-Kbyte and two 4-Kbyte blocks) to allow for independent
protection from program and erase for each block. While the CPU can access information in the flash
through a full 32-bit data bus, an external flash programmer can only perform 16-bit data bus writes to
the flash.
The flash memory of the TMP1940FDBF provides two selectable access types: one-clock access and
interleaved access.
Several options exist to program the TMP1940FDBF flash memory. On-Board Programming modes
allow for re-programming of the flash memory while the chip is soldered on a printed circuit board.
Programmer mode utilizes an EPROM programmer to perform code updates.
The TMP1940FDBF flash memory is compatible with the JEDEC standards, except a few unique
functions. Thus, it is easy to migrate from a discrete flash memory device to the on-chip flash memory
of the TMP1940FDBF. The TMP1940FDBF contains hardware to perform programming and erase
Note: These program and erase times are typical values and do not include data transfer overhead. The
Chip programming time: 6 seconds (typ.), including program verify operations

Programmer Mode
Supports use of a general-purpose EPROM programmer.
Toshiba recommends EPROM programmers from Minato Electronics, Inc. For questions
pertaining to Minato’s products, contact the following:
1) User Boot mode
2) Single Boot mode
actual chip program and erase times depend on the programming method used.
Supports use of a user-written programming algorithm.
Downloads new program code using a Toshiba-defined serial interface protocol.
