Introduction
This document provides information about the NumonyxTM AxcellTM P30-65nm Flash
memory and describes its features, operations, and specifications.
P30-65nm is the latest generation of NumonyxTM AxcellTM P30 Flash memory to the
embedded flash market segment, offered in 64-Mbit up through 2-Gbit. This document
covers specifically 512-Mbit and 1-Gbit product information. Benefits include more
density in less space, high-speed interface NOR device, and support for code and data
storage. Features include high-performance synchronous-burst read mode, a
dramatical improvement in buffer program time through larger buffer size, fast
asynchronous access times, low power, flexible security options, and two industry-
standard package choices.
P30-65nm is manufactured using Numonyx™ 65nm ETOX™ X process technology.

Overview
P30-65nm 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.
In addition to the enhanced architecture and interface, the device incorporates
technology that enables fast buffer program and erase operations. The device features
a 512-word buffer to enable optimum programming performance, which can improve
system programming throughput time significantly to 1.46MByte/s.
Designed for low-voltage systems, the P30-65nm device supports read operations with
VCC at 1.8V, and erase and program operations with VPP at 1.8V or 9.0V. Buffered
Enhanced Factory Programming provides the fastest flash array programming
performance with VPP at 9.0V, which increases factory throughput. With VPP at 1.8V,
VCC and VPP can be tied together for a simple, ultra low power design. In addition to
voltage flexibility, a dedicated VPP connection provides complete data protection when
VPP ≤ VPPLK
.
The Command User Interface is the interface between the system processor and all
internal operations of the device. An internal Write State Machine automatically
executes the algorithms and timings necessary for block erase and program. A Status
Register indicates erase or program completion and any errors that may have occurred.
A device command sequence invokes program and erase automation. Each erase
operation erases one block. The Erase Suspend feature allows system software to
pause an erase cycle to read or program data in another block. Program Suspend
allows system software to pause programming to read other locations.
P30-65nm OTP register allows unique flash device identification that can be used to
increase system security. The individual Block Lock feature provides zero-latency block
locking and unlocking. The P30-65nm device adds enhanced protection via Password
Access; this new feature allows write and/or read access protection of user-defined
blocks. In addition, the P30-65nm device also has backward compatible One-Time
Programmable (OTP) permanent block locking security feature.
