PROM) organized as (2048 +128) bytes × 64 pages × 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 × 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
increments. The Erase operation is implemented in a single block unit (128 Kbytes + 8 Kbytes: 2176 bytes × 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.
