Table 3.1 NOR Flash and RAM Input/Output Descriptions
Description
Address Inputs
Data Inputs/Outputs
Output Enable input
(Common)
Write Enable input
Ground
No Connect; not connected internally.
Ready output. Indicates the status of the Burst read.
(Flash)
Clock input. In burst mode, after the initial word is output, subsequent
active edges of CLK increment the internal address counter. Should be at (Common)
V_IL or V_IH while in asynchronous mode.
Address Valid input.
Indicates to device that the valid address is present on the address inputs.
Hardware reset input.
Hardware write protect input.
At V_IL, disables program and erase functions in the four outermost sectors.
Should be at V_IH for all other conditions.
Accelerated input.
At V_HH, accelerates programming; automatically places device in unlock
bypass mode. At V_IL, disables all program and erase functions. Should be
at V_IH for all other conditions.
Chip-enable input for pSRAM
(Flash)
Chip-enable input for Code Flash.
Chip-enable input for Data Flash 1.
Chip-enable input for Data Flash 2.
Asynchronous relative to
CLK for Burst Mode.
Control Register Enable.
(pSRAM – RAM Type 4 only)
Flash 1.8 Volt-only single power supply.
pSRAM Power Supply.
Upper Byte Control.
Lower Byte Control .
