W49L102

Preliminary W49L102 64K × 16 CMOS 3.3V FLASH MEMORY GENERAL DESCRIPTION The W49L102 is a 1-megabit, 3.3-volt only CMOS flash memory organized as 64K × 16 bits. The device can be programmed and erased in-system with a standard 3.3V power supply. A 12-volt VPP is not required. The unique cell architecture of the W49L102 results in fast program/erase operations with extremely low current consumption (compared to other comparable 3.3-volt flash memory products). The device can also be programmed and erased using standard EPROM programmers. FEATURES Single 3.3-volt operations: − 3.3-volt Read − 3.3-volt Erase − 3.3-volt Program Low power consumption − Active current: 15 mA (typ.) − Standby current: 10 µA (typ.) Fast Program operation: − Word-by-Word programming: 50 µS (max.) Fast Erase operation: 100 mS (typ.) Fast Read access time: 55/70/90 nS Endurance: 1K/10K cycles (typ.) Twenty-year data retention Hardware data protection 8K word Boot Block with Lockout protection Automatic program and erase timing with internal VPP generation End of program or erase detection − Toggle bit − Data polling Latched address and data TTL compatible I/O JEDEC standard word-wide pinouts Available packages: 40-pin TSOP and 44-pin PLCC -1- Publication Release Date: June 1999 Revision A1 Preliminary W49L102 PIN CONFIGURATIONS BLOCK DIAGRAM VDD V SS A9 A10 A11 A12 A13 A14 A15 NC WE VDD NC CE DQ15 DQ14 DQ13 DQ12 DQ11 DQ10 DQ9 DQ8 1 2 3 4 5 6 7 8 9 10 11 12 13 14...
