1 Erase can be suspended during sector erase with Addr (“H” or “L”). Data (B0h)
1 Erase can be resumed after suspend with Addr (“H” or “L”). Data (30h)
*1 : Either of the two reset commands will reset the device.
*2 : The fourth bus cycle is only for read.
Notes : • Bus operations are defined in “MBM29F017A User Bus Operations”.
• RA = Address of the memory location to be read.
IA= Autoselect read address that sets A6, A1, A0.
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 A20, A19, A18, A17, and A16 will uniquely select
any sector.
• RD = Data read from location RA during read operation.
ID= Device code/manufacture code for the address located by IA.
PD = Data to be programmed at location PA. Data is latched on the rising edge of WE.
• Read and Byte program functions to non-erasing sectors are allowed in the Erase Suspend mode.
• The command combinations not described in “MBM29F017A Command Definitions” are illegal.
