5 Chapter 1 Introduction 1 Introduction The chapter gives short overview of this application note. This application note gives a review on different Flash programming and erasing times for the MB91460 series MCU s with three different Flash programming tools: FME Flash Programmer (serial asynchronous, synchronous) Fujitsu Japan Flash Programmer (serial asynchronous) Conitec GALEP Programmer (parallel) For detailed information s on Flash programming and handling of these Flash programming tools, please refer to application note: mcu-an e-v10-mb91460_flash_programming.pdf Chapter 2 contains all timing measurements for the MB91F467D MCU and the available programming tools.

6 2 Flash programming & erasing timings MB91F467D The MB91F467DA has built-in Flash memory with a capacity of 1 MByte + 64 KBytes, capability of batch-erasing all sectors or erasing on the sector level via single +3.0V-5.5V power supply, and writing by the FR-CPU at the half-word (16-bit) and word (32-bit) level. To test the programming performance of the different flash tools, the embedded Flash is programmed with a 1088 kbytes file. To additionally get results for programming and erasing access to each available 16kByte and 128kByte sector, all sectors in figure 1 are programmed and erased individually.

7 Flash Auto Algorithm Auto Algorithms are launched by writing one to six half words (16 bits) to the Flash memory in succession. This is called a command. Writing an illegal address or data, or writing them in the incorrect order, will reset the Flash memory to read mode. o Writing o o In CPU programming mode, writes are performed in basic units of half words. Writes are performed in 4 bus operations. The command sequence as two unlock cycles, followed by a write setup command and write data cycle. Then, in the final write cycle, writing to memory starts. During writing, all commands written to Flash memory are ignored. Chip Erase Chip erase (erase all sectors at once) is performed via six accesses. First, there are two unlock cycles, after which a setup command is written. This is then followed by two more unlock commands before the chip erase command. Sector Erase Sector erase is performed via six accesses. There are two unlock cycles, after which a setup command is written, followed by another two unlock cycles. On the sixth cycle, a sector erase command is input, starting the sector erase. From the time that the last sector-erase command is written until the timeout of 50ms, the next sector-erase command will be accepted. It is possible to submit multiple sector erases simultaneously by writing the six bus cycles described above. This sequence is performed by writing the addresses of sectors to erase in succession after the sector-erase command. Fujitsu Microelectronics Europe GmbH MCU-AN E-V10

Influences of shorter chip erase times due to reduction of erase times on increasing erase cycles are ignored. MCU-AN E-V Fujitsu Microelectronics Europe GmbH
