A29L800A Series 1M x 8Bit / 512K x 16Bit CMOS 3.0 Volt-only, Boot Sector Flash Memory (March, 2006, Version 1.2) AMIC Technology, Corp. This document provides details of the 1M x 8Bit / 512K x 16Bit CMOS 3.0 Volt-only, Boot Sector Flash Memory. The document includes the product's features and characteristics, access times, current, flexible sector architecture, sector protection and extended operating temperature range.
The A29L800A is an 8Mbit Flash memory organized as 1,048,576 bytes of 8 bits or 524,288 words of 16 bits. It operates on a single 3.0V power supply (2.7V to 3.6V) and does not require an additional VPP voltage for in-system programming or erasure.
The device features flexible sector architecture with options for 16Kbyte, 8Kbyte x2, 32Kbyte, or 64Kbyte x15 sectors. It includes embedded algorithms for automatic program and erase operations, data polling via toggle bits (I/O7 and I/Os), and hardware protection methods to prevent inadvertent writes.
