DESCRIPTION
The TC58NS256 is a single 3.3-V 256-Mbit (276,824,064) bit NAND Electrically Erasable and Programmable
Read-Only Memory (NAND E
2
PROM) organized as 528 bytes
×
32 pages
×
2048 blocks. The device has a 528-byte
static register which allows program and read data to be transferred between the register and the memory cell
array in 528-byte increments. The Erase operation is implemented in a single block unit (16 Kbytes
+
512 bytes:
528 bytes
×
32 pages).
The TC58NS256 is a serial-type memory device which utilizes the I/O pins for both address and data
input/output as well as for command inputs. The Erase and Program operations are automatically executed.
The TC58NS256DC is a SmartMedia
TM
with ID and each device has 128 bit unique ID number embedded in the
device. This unique ID number is applicable to image files, music files, electronic books, and so on where copyright
protection is required.
The data stored in the TC58NS256DC needs to comply with the data format standardized by the SSFDC Forum
in order to maintain compatibility with other SmartMedia
TM
systems.
