Data Sheet
Design Considerations
SST recommends a high frequency 0.1 μF ceramic capacitor to be placed as close as possible
between V DD and V SS less than 1 cm away from the V DD pin of the device. Additionally, a low fre-
quency 4.7 μF electrolytic capacitor from V DD to V SS should be placed within 5 cm of the V DD pin. If you
use a socket for programming purposes add an additional 1-10 μF next to each socket.
Product Identification
The Product Identification mode identifies the device as the SST49LF080A and manufacturer as SST.

Mode Selection
The SST49LF080A flash memory devices can operate in two distinct interface modes: the LPC mode
and the Parallel Programming (PP) mode. The mode pin is used to set the interface mode selection. If
the mode pin is set to logic High, the device is in PP mode. If the mode pin is set Low, the device is in
the LPC mode. The mode selection pin must be configured prior to device operation. The mode pin is
internally pulled down if the pin is left unconnected. In LPC mode, the device is configured to its host
using standard LPC interface protocol. Communication between Host and the SST49LF080A occurs
via the 4-bit I/O communication signals, LAD [3:0] and LFRAME#. In PP mode, the device is pro-
grammed via an 11-bit address and an 8-bit data I/O parallel signals. The address inputs are multi-
plexed in row and column selected by control signal R/C# pin. The row addresses are mapped to the
lower internal addresses (A 10-0 ), and the column addresses are mapped to the higher internal
addresses (A MS-11 ). See Figure 4, the Device Memory Map, for address assignments.
