| HN62338B Series High Speed 1048576-word x 8-bit CMOS Mask Programmable ROM Description The HN62338B is a 8-Mbit CMOS mask-programmable ROM organized as 1048576 words by 8 bits. In addition, the HN62338B, which provides large capacity of 8M bits, is ideally suited for kanji character generators. Features * Single +5V power supply * Maximum access time: 150 ns (max) Low power consumption: 250 mW (typ) active5 W (typ) standby * Byte-wide data organization * Pin compatible with JEDEC Ordering Information Type No. HN62338BP-15 HN62338BF-15 Access Time 150 ns 150 ns Package 600 mil 32-pin plastic DIP (DP-32) 32-pin plastic SOP (FP-32D) HN62338B Series Pin Arrangement A19 A16 A15 A12 A7 A6 A5 A4 A3 A2 A1 A0 D0 D1 D2 VSS 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 (Top view) 32 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 VCC A18 A17 A14 A13 A8 A9 A11 OE A10 CE D7 D6 D5 D4 D3 Block Diagram A0 Address buffer Memory array 3-state output buffer D0 to to A19 D7 CE OE 2 HN62338B Series Absolute Maximum Ratings Parameter Supply voltage All input and output voltage Operating temperature range Storage temperature range Temperature under bias Note: 1.
