10 / 39 page www.national.com 10 Revision 3.2 Signal Definitions (Continued) DISPOFF# 131 O (12 mA) Disables Panel When this output is asserted low, it indicates that the LCD panel should be disabled. FP_VDDEN 130 O (12 mA) Controls LCD VDD FET When this output is asserted high, voltage should be applied to the panel. This signal is intended to control a power FET to the LCD panel. FP_VCONEN 129 O (12 mA) Controls LCD Bias Voltage Enable When this output is asserted high, the contrast voltage (VCON) should be applied to the panel. 2.2.3 Flat Panel Interface Signals (Continued) Signal Name Pin No. Type (Drive) Description 2.2.4 Memory Interface Signals Signal Name Pin No. Type (Drive) Description MA_A[9:0] 23-32 O (4 mA) DRAM Bank A Address Bus The address bus for Bank A of the DRAM. MD_A[15:0] 33-35, 39-51 I/O (4 mA) DRAM Bank A Data Bus The data bus for Bank A of the DRAM. MA_B[9:0] 95-92, 88-83 O (4 mA) DRAM Bank B Address Bus The address bus for Bank B of the DRAM. MD_B[15:0] 82-74, 70-64 I/O (4 mA) DRAM Bank B Data Bus The data bus for Bank B of the DRAM. OEA# 53 O (4 mA) DRAM Bank A Output Enable The output enable for Bank A of the DRAM. OEB# 63 O (4 mA) DRAM Bank B Output Enable The output enable for Bank B of the DRAM. RASA# 57 O (4 mA) DRAM Bank A Row Address Strobe The row address strobe for Bank A of the DRAM. RASB# 60 O (4 mA) DRAM Bank B Row Address Strobe The row address strobe for Bank B of the DRAM. UCASA# 52 O (4 mA) DRAM Bank A High Byte Column Address Strobe The column address strobe for the upper eight bits of data for Bank A of the DRAM. LCASA# 56 O (4 mA) DRAM Bank A Low Byte Column Address Strobe The column address strobe for the lower eight bits of data for Bank A of the DRAM. UCASB# 62 O (4 mA) DRAM Bank B High Byte Column Address Strobe The column address strobe for the upper eight bits of data for Bank B of the DRAM. |
