Overview
A29001/290011 Series 128K 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 (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 Kbyte/ 4 KbyteX2/ 16 Kbyte/ 32 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 A290011) n Package options - 32-pin P-DIP, PLCC, or TSOP (Forward type) Boot Sector Flash Memory General Description The A29001 is a 5.
0 volt-only Flash memory organized as 131,072 bytes of 8 bits each.
The A29001 offers the RESET function, but it is not available on A290011.
The 128 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 A16.
