Description The µPD23C256112A is a 256 Mbit NAND interface programmable mask read-only memory that operates with a single power supply. The memory organization consists of (512 + 16 (Redundancy)) bytes x 32 pages x 2,048 blocks. The µPD23C256112A is a serial type mask ROM in which addresses and commands are input and data output serially via the I/O pins. The µPD23C256112A is packed in 48-pin PLASTIC TSOP(I). Features • Word organization (33,554,432 + 1,048,576 Note) words by 8 bits • Page size (512 + 16 Note) by 8 bits • Block size (16,384 + 512 Note) by 8 bits Note Underlined parts are redundancy. Caution Redundancy is not programmable parts and is fixed to all FFH. • Operation mode READ mode (1), READ mode (2), READ mode (3), RESET, STATUS READ, ID READ • Operating supply voltage : VCC = 3.3 ± 0.3 V • Access Time Memory cell array to starting address : 7 µs (MAX.) Read cycle time : 50 ns (MIN.) /RE access time : 35 ns (MAX.) • Operating supply current During read : 30 mA (MAX.) (50 ns cycle operation) During standby (CMOS) : 100 µA (MAX.)
