Overview
Preliminary W49F201 128K × 16 CMOS FLASH MEMORY GENERAL DESCRIPTION The W49F201 is a 2-megabit, 5-volt only CMOS flash memory organized as 128K × 16 bits.
The device can be programmed and erased in-system with a standard 5V power supply.
A 12-volt VPP is not required.
The unique cell architecture of the W49F201 results in fast program/erase operations with extremely low current consumption (compared to other comparable 5-volt flash memory products).
The device can also be programmed and erased using standard EPROM programmers.
FEATURES • Single 5-volt operations: − 5-volt Read/Erase/Program Fast Program operation: − Word-by-Word programming: 50 µS (max.
) Fast Erase operation: 60 mS (typ.
) Fast Read access time: 45/55 nS Endurance: 1K/10K cycles (typ.
) Ten-year data retention Hardware data protection Sector configuration − One 8K words boot block with lockout protection − Two 8K words parameter blocks − One 104K words (208K bytes) Main Memory Array Blocks • Low power consumption − Active current: 25 mA (typ.
) − Standby current: 20 µA (typ.
) • • • • • • • • • 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: 44-pin SOP, 48-pin TSOP -1- Publication Release Date: June 1999 Revision A1 Preliminary W49F201 PIN CONFIGURATIONS BLOCK DIAGRAM VDD VSS NC NC NC A7 A6 A5 A4 A3 A2 A1 A0 CE GND OE DQ0 DQ8 DQ1 DQ9 DQ2 DQ10 DQ3 DQ11 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 44 43 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 24 23 44-pin SOP RESET WE A8 A9 A10 A11 A12 A13 A14 A15 A16 NC GND DQ15 DQ7 DQ14 DQ6 DQ13 DQ5 DQ12 DQ4 VCC CE OE WE RESET CONTROL OUTPUT BUFFER DQ0 .
