The cost is included in the unit price. * Custom Marking is available at no additional charge. * Pin Compatible with Mask ROM and some FLASH products. 44 A20 2 43 A19 3 42 A8 4 41 A9 5 40 A10 6 39 A11 7 38 A12 8 37 A13 9 36 A14 10 35 A15 11 34 A16 12 33 BYTE# 13 32 VSS 14 31 D15/A-1 15 30 D7 16 29 D14 17 28 D6 18 27 D13 19 26 D5 20 25 D12 21 24 D4 22 23 VCC 44SOP, 44TSOP(Type-II) P2ROM ADVANCED TECHNOLOGY P2ROM stands for Production Programmed ROM. This exclusive LAPIS Semiconductor's technology utilizes factory test equipment for programming the customers code into the P2ROM prior to final production testing. Advancements in this technology allows production costs to be equivalent to MASKROM and has many advantages and added benefits over the other non-volatile technologies, which include the following; 1 A15 A14 A13 A12 A11 A10 A9 A8 A19 A20 NC NC NC NC NC A18 A17 A7 A6 A5 A4 A3 A2 A1 1 48 A16 2 47 BYTE# 3 46 VSS 4 45 D15/A-1 5 44 D7 6 43 D14 7 42 D6 8 41 D13 9 40 D5 10 39 D12 11 38 D4 12 37 VCC 13 36 D11 14 35 D3 15 34 D10 16 33 D2 17 32 D9 18 31 D1 19 30 D8 20 29 D0 21 28 OE# 22 27 VSS 23 26 CE# 24 25 A0 48TSOP(Type-I) 1/10 FEDR27T3202F-002-04 MR27T3202F / P2ROM BLOCK DIAGRAM A-1 OE# CE OE BYTE# Row Decoder CE# Memory Cell Matrix 2M x 16-Bit or 4M x 8-Bit Column Decoder A0 A1 A2 A3 A4 A5 A6 A7 A8 A9 A10 A11 A12 A13 A14 A15 A16 A17 A18 A19 A20 Address Buffer x 8/x 16 Switch Multiplexer Output Buffer D0 D2 D1 D4 D3 D6 D5 D8 D7 D10 D9 D12 D11 D14 D13 D15 In 8-bit output mode, these pins are placed in a high-Z state and pin D15 functions as the A-1 address pin.
