INFORM ATION
PIN DESCRIPTION
A20–A0
= 21 Address Inputs (Common)
A21
= Address Input (Flash)
A22
= Address Input (PDL127 only)
(Flash)
DQ15–DQ0
= 16 Data Inputs/Outputs (Common)
CE#f1
= Chip Enable 1 (Flash)
CE#f2
= Chip Enable 2 (Flash)
(PDL129 Only)
CE#1ps
= Chip Enable 1 (pSRAM)
CE2ps
= Chip Enable 2 (pSRAM)
OE#
= Output Enable (Common)
WE#
= Write Enable (Common)
RY/BY#
= Ready/Busy Output and open drain.
When RY/BY# = V
IH, the device is
ready to accept read operations and
commands. When RY/BY# = VOL,
the device is either executing an em-
bedded algorithm or the device is
executing a hardware reset opera-
tion.
UB#s
= Upper Byte Control (pSRAM)
LB#s
= Lower Byte Control (pSRAM)
RESET#
= Hardware Reset Pin, Active Low
WP#/ACC
= Write Protect/Acceleration Input.
When WP/ACC#= V
IL, the highest
and lowest two 4K-word sectors are
write protected regardless of other
sector protection configurations.
When WP/ACC#= V
IH, these sector
are unprotected unless the DYB or
PPB is programmed. When
WP/ACC#= 12V, program and erase
operations are accelerated.
V
CCf
= Flash 3.0 volt-only single power sup-
ply (see Product Selector Guide for
speed options and voltage supply
tolerances)
V
CCs
= pSRAM Power Supply
V
SS
= Device Ground (Common)
ds
= Data Storage
NC
= Pin Not Connected Internally
CE#1ds
= Chip Enable 1 (Am29LV640MH
Flash- Data Storage)
CE#2ds
= Chip Enable 2 (Am29LV640MH
Flash- Data Storage)
RY/BY#
= READY/BUSY Output (Data Stor-
age)
RESET#ds
= Hardware Reset Pin, Active Low
(Data Storage)
WP#/ACCds
= Write Protect/Acceleration Input
(Data Storage)
