Overview
A29002/A290021 Series 256K X 8 Bit CMOS 5.
0 Volt-only, Boot Sector Flash Memory 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 - 16 Kbyte/ 8 KbyteX2/ 32 Kbyte/ 64 KbyteX3 sectors - 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 Top or bottom boot block configurations available 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 n Typical 100,000 program/erase cycles per sector n 20-year data retention at 125°C - Reliable operation for the life of the system n Compatible with JEDEC-standards - Pinout and software compatible with single-powersupply Flash memory standard - Superior inadvertent write protection n Data Polling and toggle bits - Provides a software method of detecting completion of program or erase operations n 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 n Hardware reset pin ( RESET ) - Hardware method to reset the device to reading array data (not available on A290021) n Package options - 32-pin P-DIP, PLCC, or TSOP (Forward type) General Description The A29002 is a 5.
0 volt-only Flash memory organized as 262,144 bytes of 8 bits each.
The A29002 offers the RESET function, but it is not available on A290021.
The 256 Kbytes of data are further divided into seven sectors for flexible sector erase capability.
The 8 bits of data appear on I/O0 I/O7 while the addresses are input on A0 to A17.
