Description

Amax – A0

Address Inputs

(Common)

DQ15 - DQ0

Data Inputs/Outputs

OE#

Output Enable input

WE#

Write Enable input

VSS

Ground

No Connect; not connected internally.

RDY

Ready output. Indicates the status of the Burst read.

(Flash)

CLK

Clock input. In burst mode, after the initial word is output, subsequent

active edges of CLK increment the internal address counter. Should be at

VIL or VIH while in asynchronous mode.

(Common)

AVD#

Address Valid input.

Indicates to device that the valid address is present on the address inputs.

(Flash)

F-RST#

Hardware reset input.

F-WP#

Hardware write protect input.

At VIL, disables program and erase functions in the four outermost sectors.

Should be at VIH for all other conditions.

F-ACC

Accelerated input.

At VHH, accelerates programming; automatically places device in unlock

bypass mode. At VIL, disables all program and erase functions. Should be

at VIH for all other conditions.

R-CE#

Chip-enable input for pSRAM

F-CE#

Chip-enable input for Flash.

Asynchronous relative to

CLK for Burst Mode.

F1-CE#

Chip-enable input for Flash 1.

F2-CE#

Chip-enable input for Flash 2.

F3-CE#

Chip-enable input for Flash 3.

R-CRE

Control Register Enable .

(pSRAM – CellularRAM only)

F-VCC

Flash 1.8 Volt-only single power supply.

R-VCC

pSRAM Power Supply.

R-UB#

Upper Byte Control.

(pSRAM)

R-LB#

Lower Byte Control .

Note: R-CRE is only present in CellularRAM-compatible pSRAM.
