8 / 49 page MBM29F160TE70/90/MBM29F160BE70/90 8 MBM29F160TE/BE Standard Command Definitions Table *1 : Address bits A19 to A11 = X = “H” or “L” for all address commands except or Program Address (PA) and Sector Address (SA). *2 : Bus operations are defined in “MBM29F160TE/BE User Bus Operation Tables (BYTE = VIH and BYTE = VIL)”. *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 WE pulse. SA = Address of the sector to be erased. The combination of A19, A18, A17, A16, A15, A14, A13 and A12 will uniquely select any sector. *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 WE. *5 : The system should generate the following address patterns: Word Mode: 555h or 2AAh to addresses A10 to A0 Byte Mode: AAAh or 555h to addresses A10 to A-1 *6 : Both Read/Reset commands are functionally equivalent, resetting the device to the read mode. Note : The command combinations not described in “MBM29F160TE/BE Standard Command Definitions Table” and “MBM29F160TE/BE Extended Command Definitions Table” are illegal.
