Description
A29040 Series
512K X 8 Bit CMOS 5.0 Volt-only, Preliminary
Features
n 5.0V ± 10% for read and write operations n Access times: - 55/70/90/120/150 (max.) n Current: - 20 mA typical active read current - 30 mA typical program/erase current - 1 µA typical CMOS standby n Flexible sector architecture - 8 uniform sectors of 64 Kbyte each - Any combination of sectors can be erased - Supports full chip erase - Sector protection: A hardware method of protecting sectors to prevent any inadvertent program or erase operations within that sector n Embedded Erase Algorithms - Embedded Erase algorithm will automatically erase the entire chip or any combination of designated sectors and verify the erased sectors - Embedded Program algorithm automatically writes and verifies bytes at specified addresses Typical 100,000 program/erase cycles per sector 20-year data retention at 125°C - Reliable operation for the life of the system Compatible with JEDEC-standards - Pinout and software compatible with single-powersupply Flash memory standard - Superior inadvertent write protection Data Polling and toggle bits - Provides a software method of detecting completion of program or erase operations Erase Suspend/Erase Resume - Suspends a sector erase operation to read data from, or program data to, a non-erasing sector, then resumes the erase operation Package options - 32-pin P-DIP, PLCC, or TSOP(Forward type)
