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 minimize 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. 48 47 46 45 44 43 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 A15 A14 A13 A12 A11 A10 A9 A8 A19 A20 NC NC A21 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 48TSOP(Type-I) PIN CONFIGURATION (TOP VIEW) 44 43 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 24 23 A21 A18 A17 A7 A6 A5 A4 A3 A2 A1 A0 CE# VSS OE# D0 D8 D1 D9 D2 D10 D3 D11 A20 A19 A8 A9 A10 A11 A12 A13 A14 A15 A16 BYTE# VSS D15/A–1 D7 D14 D6 D13 D5 D12 D4 VCC 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 44SOP 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 |
