• Manufacturer Part Number: SST49LF004B-33-4C-WHE
• Description: 4 Mbit Firmware Hub
• Manufacturer: SST [Silicon Storage Technology, Inc]

Preliminary Specifications
DEVICE MEMORY MAP
DESIGN CONSIDERATIONS
SST recommends a high frequency 0.1 µF ceramic capac-
itor to be placed as close as possible between V
V
Additionally, a low frequency 4.7 µF electrolytic capacitor
from V
pin. If a socket is used for programming purposes, an addi-
tional 1-10 µF should be added next to each socket.
The RST# and INIT# pins must remain stable at V
entire duration of an Erase or Program operation. WP#
must remain stable at V
Erase and Program operations for non-Boot Block sectors.
To write data to the top Boot Block sectors, the TBL# pin
must also remain stable at V
Erase and Program operations.

PRODUCT IDENTIFICATION
The Product Identification mode identifies the device as the
SST49LF004B and manufacturer as SST.
TABLE 2: P
Manufacturer’s ID
Device ID
1. Address shown in this column is for boot device only.
2. The device ID for SST49LF004B is the same as
SST49LF004B
Address locations should appear elsewhere in the 4
GByte system memory map depending on ID strapping
values on ID[3:0] pins when multiple LPC memory
devices are used in a system.
