Table 4.
Odd Byte Command Definitions (Notes 1–5)
* Address for Memory Segment 1 (S1) only. Address for the higher odd memory segments (S3–S15) = (Addr) + ((N–1)/2)*
400000H + 20000H where N = Memory Segment number (1) for 4 Mbyte, N = (1, 3) for 8 Mbyte, N = (1, 3, 5) for 12 Mbyte,
N = (1…9) for 20 Mbyte, N = (1...15) for 32 Mbyte.
Notes:
1. Address bits = X = Don’t Care for all address commands except for Program Address (PA), Read Address (RA) and Sector
Address (SA).
2. Bus operations are defined in Table 1.
3. RA = Address of the memory location to be read.
PA = Address of the memory location to be programmed. Addresses are latched on the falling edge of the WEpulse.
SA = Address of the sector to be erased. The combination of A17, A18, A19, A20, A21 will uniquely select any sector of a
segment.
To select the memory segment:
4 Mbyte:
Use CE2
8 Mbyte:
Use CE2 and A22
20 and 32 Mbyte:
Use CE2 and A22–A24.
4. RD = Data read from location RA during read operation.
PD = Data to be programmed at location PA. Data is latched on the rising edge of WEpulse.
5. A0 = 1 and CE1 = 0 or A0 = X and CE2 = 0.
