S71151-07-000 8/06 FIGURE 4: Pin Assignments for 32-pin PDIP Note: X = VIL or VIH (or VH in case of OE# and A9) VH = 11.4-12V TABLE 2: Pin Description Symbol Pin Name Functions AMS1-A0 1. AMS = Most significant address AMS = A15 for SST37VF512, A16 for SST37VF010, A17 for SST37VF020, and A18 for SST37VF040 Address Inputs To provide memory addresses. DQ7-DQ0 Data Input/output To output data during Read cycles and receive input data during Program cycles. The outputs are in tri-state when OE# or CE# is high. CE# Chip Enable To activate the device when CE# is low. WE# Write Enable To program or erase (WE# = VIL pulse during Program or Erase) OE# Output Enable To gate the data output buffers during Read operation when low VDD Power Supply To provide 3.0V supply (2.7-3.6V) VSS Ground NC No Connection Unconnected pins.
