The features of the flash memory are summarized below.
The block diagram of the flash memory is shown in figure 19.1.
19.1
Size: 128 kbytes
Programming/erase methods
Reprogramming capability
Three programming modes
Programmer mode
Automatic bit rate adjustment
Programming/erasing protection
The flash memory is programmed 128 bytes at a time. Erase is performed in single-block
units. The flash memory is configured as follows: 32 kbytes
block, 16 kbytes
flash memory, each block must be erased in turn.
The flash memory can be reprogrammed up to 100 times.
Boot mode
User mode
Programmer mode
On-board programming/erasing can be done in boot mode, in which the boot program built
into the chip is started to erase or program of the entire flash memory. In normal user
program mode, individual blocks can be erased or programmed.
Flash memory can be programmed/erased in programmer mode using a PROM
programmer, as well as in on-board programming mode.
For data transfer in boot mode, this LSI’s bit rate can be automatically adjusted to match
the transfer bit rate of the host.
Sets software protection against flash memory programming/erasing.
