    GENERAL DESCRIPTION The W29C020 is a 2-megabit, 5-volt only CMOS flash memory organized as 256K x 8 bits. The device can be written (erased and programmed) in-system with a standard 5V power supply. A 12-volt VPPis not required. The unique cell architecture of the W29C020 results in fast write (erase/program) operations with extremely low current consumption compared to other comparable 5-volt flash memory products. The device can also be written (erased and programmed) by using standard EPROM programmers. FEATURES · Single 5-volt write (erase and program) operations · Fast page-write operations \- 128 bytes per page \- Page write (erase/program) cycle: 10 mS (max.) \- Effective byte-write (erase/program) cycle time: 39 mS \- Optional software-protected data write · Fast chip-erase operation: 50 mS · Two 8 KB boot blocks with lockout · Typical page write (erase/program) cycles: 100/1K/10K · Read access time: 70/90/120 nS · Ten-year data retention · Software and hardware data protection · Low power consumption \- Active current: 25 mA (typ.) \- Standby current: 20 mA (typ.) · Automatic write (erase/program) timing with internal VPP generation · End of write (erase/program) detection \- Toggle bit \- Data polling · Latched address and data · All inputs and outputs directly TTL compatible · JEDEC standard byte-wide pinouts · Available packages: 32-pin 600 mil DIP, 450 mil SOP, TSOP, and 32-pin PLCC
