1 / 10 page AT29LV256 256K (32K x 8) 3-volt Only CMOS Flash Memory Features • Single Supply Voltage, Range 3V to 3.6V • 3-Volt-Only Read and Write Operation • Software Protected Programming • Low Power Dissipation 15 mA Active Current 20 µA CMOS Standby Current • Fast Read Access Time - 200 ns • Sector Program Operation Single Cycle Reprogram (Erase and Program) 512 Sectors (64 bytes/sector) Internal Address and Data Latches for 64-Bytes • Fast Sector Program Cycle Time - 20 ms Max. • Internal Program Control and Timer • DATA Polling for End of Program Detection • Typical Endurance > 10,000 Cycles • CMOS and TTL Compatible Inputs and Outputs • Commercial and Industrial Temperature Ranges Description The AT29LV256 is a 3-volt-only in-system Flash Programmable Erasable Read Only Memory (PEROM). Its 256K of memory is organized as 32,768 words by 8 bits. Manufactured with Atmel’s advanced nonvolatile CMOS technology, the device offers access times to 200 ns with power dissipation of just 54 mW over the commercial temperature range. When the device is deselected, the CMOS standby current is less than 20 µA. The device endurance is such that any sector can typically be written to in excess of 10,000 times.
