7.3.  U405 (TC58NVG0S3HTAI0 only for LC-50LD266)   
General Description   
The TC58NVG0S3HTAI0 is a single 3.3V 1Gbit (1,140,850,688bits) NAND Electrically Erasable and Programmable Read-Only 
Memory (NAND E
2
PROM) organized as (2048 +128) bytes 
ǘ 64 pages ǘ 1024blocks. The device has a 2176-byte static 
registers which allow program and read data to be transferred between the register and the memory cell array in 2176-byte 
increments. The Erase operation is implemented in a single block unit (128 Kbytes + 8 Kbytes: 2176 bytes 
ǘ 64 pages). The 
TC58NVG0S3HTAI0 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 making the device most suitable for 
applications such as solid-state file storage, voice recording, image file memory for still cameras and other systems which 
require high-density non-volatile memory data storage.
