Am29LV160D Product Overview
16 Megabit (2M x 8-Bit/1M x 16-Bit)
CMOS 3.0 Volt-only Boot Sector Flash Memory
General Description
The Am29LV160D is a 16 Mbit, 3.0 Volt-only Flash. This device is designed to be programmed in-system with the standard system 3.0 Volt VCC supply. A 12.0V VPP or 5.0 VCC are not required for write or erase operations. The device can also be programmed in standard EPROM programmers. The device offers access times of 70, 90, and 120 ns, allowing high speed microprocessors to operate without wait states. The device is offered in 48-ball FBGA, 44-pin SO, and 48-pin TSOP packages.
Distinctive Characteristics
Architectural Advantages
- Single power supply operation
- Full voltage range: 2.7 to 3.6 Volt read and write operations for battery-powered applications
- Regulated voltage range: 3.0 to 3.6 Volt read and write operations and for compatibility with high performance 3.3 Volt microprocessors
- Manufactured on 0.32 µm process technology
- Fully compatible with 0.32 µm Am29LV160B device
