The Am28F010 is a 1 Megabit Flash memory orga- nized as 128 Kbytes of 8 bits each. AMD’s Flash mem- ories offer the most cost-effective and reliable read/ write non-volatile random access memory. The Am28F010 is packaged in 32-pin PDIP, PLCC, and TSOP versions. It is designed to be reprogrammed and erased in-system or in standard EPROM pro- grammers. The Am28F010 is erased when shipped from the factory. The standard Am28F010 offers access times as fast as 70 ns, allowing operation at clock speeds in excess of 100 MHz.
The Am28F010 is a 1 Megabit (128 K × 8‑bit) CMOS flash memory offered by AMD. It is available in 32‑pin PDIP, PLCC and TSOP packages and can be programmed and erased in‑system using standard microprocessor interfaces. The device provides high‑speed access (up to 70 ns) with low power consumption and latch‑up protection.
The datasheet describes the distinctive characteristics, pin descriptions, command register operation, erase/program sequences, data‑protection features, physical dimensions and revision history. It also includes ordering information, valid product combinations and speed options.

The Am28F010 programs a byte in about 10 µs using the Flashrite™ algorithm.
The device is rated for a minimum of 10,000 write/erase cycles.
The fastest speed option provides a maximum access time of 70 ns.
Erase and program operations use a 12.0 V ±5 % high‑voltage input on the Vpp pin.
