This exclusive Oki 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; · Short lead time, since the P2ROM is programmed at the final stage of the production process, a large P2ROM inventory "bank system" of un-programmed packaged products are maintained to provide an aggressive lead-time and minimizes liability as a custom product. · No mask charge, since P2ROMs do not utilize a custom mask for storing customer code, no mask charges apply. · No additional programming charge, unlike Flash and OTP that require additional programming and handling costs, the P2ROM already has the code loaded at the factory with minimal effect on the production throughput. 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. 44SOP, 44TSOP(Type-II) A15 A14 A13 A12 A11 A10 A9 A8 A19 NC NC NC NC NC NC A18 A17 A7 A6 A5 A4 A3 A2 A1 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 48 47 46 45 44 43 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 A16 BYTE# VSS D15/A–1 D7 D14 D6 D13 D5 D12 D4 VCC D11 D3 D10 D2 D9 D1 D8 D0 OE# VSS CE# A0 48TSOP(Type-I) 1/10 FEDR27T1602F-02-02 OKI Semiconductor MR27T1602F/P2ROM BLOCK DIAGRAM A–1 × 8/× 16 Switch CE# CE OE# OE BYTE# Column Decoder A0 A1 A2 A3 A4 A5 A6 A7 A8 A9 A10 A11 A12 A13 A14 A15 A16 A17 A18 A19 Row Decoder Memory Cell Matrix 1M × 16-Bit or 2M × 8-Bit Address Buffer Multiplexer Output Buffer D0 D1 D2 D3 D4 D5 D6 D7 D8 D9 D10 D12 D14 D15 D11 D13 In 8-bit output mode, these pins are placed in a high-Z state and pin D15 functions as the A-1 address pin.
