Description
The
碌
PD29F064115-X is a flash memory organized of 67,108,864 bits and 142 sectors. Sectors of this memory can
be erased at a low voltage (1.65 to 1.95 V, 1.8 to 2.1 V ) supplied from a power source, or the contents of the entire
chip can be erased. Memory organization is 4,194,304 words
脳
16 bits, so that the memory can be programmed in
word units.
碌
PD29F064115-X can be read high speed with page mode.
The
碌
PD29F064115-X can be read while its contents are being erased or programmed. The memory cell is divided
into four banks. While sectors in any bank are being erased or programmed, data can be read from the other three
banks thanks to the simultaneous execution architecture. The banks are 8M bits, 24M bits, 24M bits and 8M bits.
Input /output voltage is supplied to 2.7 to 3.3 V.
Because the
碌
PD29F064115-X enables the boot sector to be erased, it is ideal for storing a boot program. In
addition, program code that controls the flash memory can be also stored, and the program code can be programmed
or erased without the need to load it into RAM. 16 small sectors for storing parameters are provided, each of which
can be erased in 4K words units.
Once a program or erase command sequence has been executed, an automatic program or automatic erase
function internally executes program or erase and verification automatically. The programming time is about 0.5
seconds per sector. The erase time is less than 1 second per sector.
Because the
碌
PD29F064115-X can be electrically erased or programmed by writing an instruction, data can be
reprogrammed on-board after the flash memory has been installed in a system, making it suitable for a wide range of
applications.
This flash memory is packed in 48-pin PLASTIC TSOP (I), 63-pin TAPE FBGA and 85-pin TAPE FBGA.
