S71107-03-000 5/01 349 FIGURE 2: PIN ASSIGNMENTS FOR 32-LEAD TSOP (8MM X 14MM) - SSTLF041A/043A TABLE 2: PIN DESCRIPTION Symbol Pin Name Functions AMS1-A0 1. AMS = Most significant address Address Inputs To provide memory addresses. A18-A0 to provide flash address A16-A0 to provide SRAM addresses for SST32LF041/041A A14-A0 to provide SRAM addresses for SST31LF043/043A During flash Sector-Erase, A18-A12 address lines will select the sector. DQ7-DQ0 Data Input/output To output data during Read cycles and receive input data during Write cycles. Data is internally latched during a flash Erase/Program cycle. The outputs are in tri-state when OE# or BES# and BEF# are high. BES# SRAM Memory Bank Enable To activate the SRAM memory bank when BES# is low. Note: For SST31LF041A/043A, BES# and OE# share pin 32. BEF# Flash Memory Bank Enable To activate the Flash memory bank when BEF# is low. OE# Output Enable To gate the data output buffers. Note: For SST31LF041A/043A, BES# and OE# share pin 32. WE# Write Enable To control the Write operations.
