Addressing the Flash Which is Organized in Pages

Note:

1. PCPAGE and PCWORD are listed in 

Note:

1. “XX” is don’t care. The letters refer to the programming description above.

The EEPROM is organized in pages, see 

. When programming the EEPROM, the 

program data is latched into a page buffer. This allows one page of data to be programmed simultaneously. The 
programming algorithm for the EEPROM data memory is as follows (refer to 

 for details on Command, Address and Data loading):

1. A: Load Command “0001 0001”.

2.

G: Load Address High Byte (0x00 - 0xFF).

3.

B: Load Address Low Byte (0x00 - 0xFF).

4.

C: Load Data (0x00 - 0xFF).

5.

E: Latch data (give PAGEL a positive pulse).

K: Repeat 3 through 5 until the entire buffer is filled.
