BUILT-IN FLASH ROM PROGRAMMING
The robust features of the flash permit simple and optimized programming as well as maintaining the flash-ROM.
(1) Programming Method
Programming via JTAG interface
Programming using boot mode
Boot mode of this LSI is used for downloading data to be written to the FLASH through the UART
interface of the MCU from a host system.
In boot mode, the program on the on-chip boot ROM
downloads a flash writing application, that will handle the serial transfer and writing of internal flash, to
internal RAM area of the MCU through the UART interface of the MCU.
Programming via user application running from external memory
Internal flash can be programmed by executing a user flash programming application from external
memory.
(2) Single power source for Read/Program of FLASH: 3.0V to 3.6V
(3) Programming units : 2 bytes
(4) Selectable erasing size
Sector erase: 2Kbytes/sector
Block erase: 64Kbytes/block
Chip erase: All memory cell
(5) Word program time: 30usec
(6) Sector/block erase time: 25msec
(7) Chip erase time: 100msec
(8) Write protection
Block protect: top address 8Kwords can be protected
Chip protect: all words can be protected
(9) Number of commands: 9
(10) Highly reliable read/program
Sector programming: 1000 times
Data hold period: 10 years
