PD29F032202AL-Y
32M-BIT CMOS LOW-VOLTAGE DUAL OPERATION FLASH MEMORY
4M-WORD BY 8-BIT (BYTE MODE) / 2M-WORD BY 16-BIT (WORD MODE)
MOS INTEGRATED CIRCUIT
Description
The
µ
PD29F032202AL-Y is a flash memory organized of 33,554,432 bits and 71 sectors. Sectors of this memory
can be erased at a low voltage (2.7 to 3.3 V, 3.0 to 3.6 V) supplied from a single power source, or the contents of the
entire chip can be erased. Two modes of memory organization, BYTE mode (4,194,304 words
×
8 bits) and WORD
mode (2,097,152 words
×
16 bits), are selectable so that the memory can be programmed in byte or word units.
The
µ
PD29F032202AL-Y can be read while its contents are being erased or programmed. The memory cell is
divided into two banks. While sectors in one bank are being erased or programmed, data can be read from the other
bank thanks to the simultaneous execution architecture. The banks are 4M bits and 28M bits.
This flash memory comes in two types. The T type has a boot sector located at the highest address (sector) and the
B type has a boot sector at the lowest address (sector).
Because the
µ
PD29F032202AL-Y 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. Eight small sectors for storing parameters are provided,
each of which can be erased in 8K bytes 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.
Because the
µ
PD29F032202AL-Y 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 a 48-pin PLASTIC TSOP (I) and 63-pin TAPE FBGA.
