Introduction
This document provides information about the Numonyx® AxcellTM P30-65nm Single Bit per Cell (SBC) Flash memory and describes its features, operations, and specifications.

Overview
P30-65nm SBC device provides high performance on a 16-bit data bus. Individually erasable memory blocks are sized for optimum code and data storage. Upon initial power-up or return from reset, the device defaults to asynchronous page-mode read. Configuring the Read Configuration Register (RCR) enables synchronous burst-mode reads. In synchronous burst mode, output data is synchronized with a user-supplied clock signal. A WAIT signal provides easy CPU-to-flash memory synchronization.
