| GENERAL DESCRIPTION The Am29F200B is a 2 Mbit, 5.0 Volt-only Flash memory organized as 262,144 bytes or 131,072 words. The 8 bits of data appear on DQ0–DQ7; the 16 bits on DQ0–DQ15. The Am29F200B is offered in 44-pin SO and 48-pin TSOP packages. The device is also available in Known Good Die (KGD) form. For more information, refer to publication number 21257. This device is designed to be programmed in-system with the standard system 5.0 volt VCC supply. A 12.0 volt VPP is not required for program or erase operations. The device can also be reprogrammed in standard EPROM programmers. DISTINCTIVE CHARACTERISTICS ■ 5.0 V for read and write operations — Minimizes system level power requirements ■ Manufactured on 0.32 µm process technology — Compatible with 0.5 µm Am29F200A device ■ High performance — Access times as fast as 45 ns ■ Low power consumption — 20 mA typical active read current (byte mode) — 28 mA typical active read current for (word mode) — 30 mA typical program/erase current — 1 µA typical standby current ■ Sector erase architecture — One 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and three 64 Kbyte sectors (byte mode) — One 8 Kword, two 4 Kword, one 16 Kword, and three 32 Kword sectors (word mode) — Supports full chip erase — Sector Protection features: A hardware method of locking a sector to prevent any program or erase operations within that sector Sectors can be locked via programming equipment Temporary Sector Unprotect feature allows code changes in previously locked sectors ■ Top or bottom boot block configurations available |
