3.0 Volt-only Page Mode Technology Background
Introduction
AMD, the technology leader in Flash memories, has developed a new generation of high-
performance, single-power-supply flash memory devices. The Am29PL160C is the first page
mode low-voltage flash memory device from AMD. This device allows read access times as
fast as 25 ns, and performs all read, program, and erase operations using only a single 2.7 volt
power supply. These devices offer all of the features of AMD’s industry-standard 2.7 volt-
only Am29LVxxx devices with substantially faster access times, making it the ideal choice for
low-power, high performance applications. In addition, this device is 5 volt I/O tolerant
allowing it to be easily used in 5 volt systems. The Am29PL160C device supports an industry
standard 8-word page size. This 8-word page size gives system designers the added flexibility
of being able to support not only 8-word page size processors, but also 4-word page size
processors as well.
The following is an abbreviated list of the Am29PL160C distinctive characteristics:
J
25 ns page access time
J
65 ns initial access time
J
2.7 V to 3.6 V device V
CC
operating range
J
5 V I/O tolerant on data, address, and control signals
J
8-word page size
J
Minimum 1,000,000 program/erase cycles guaranteed per sector
For a complete list of features, operational description and specifications see publication
number 22143 (Am29PL160C data sheet).
In many low cost consumer applications, the control code is typically stored in masked ROM.
Masked ROM does not offer any flexibility as far as updating code stored in the ROM. This
places severe limitations on time-to-market, as well as manufacturing efficiency. Typically
during the prototyping phase of a product, the control code is updated several times to include
new features and fix bugs. Each time there is a modification to the code, a new masked ROM
must be spun to store the modified code, as masked ROM is not erasable. Given the average
number of fixes to the code prior to production, this can add up to a significant amount of
development time and money.
The Am29PL160C allows system designers to take advantage of the reprogrammability of
flash during the design and initial production phases—when they need flexibility the most—
and then switch to masked ROM when that flexibility is no longer needed. This is possible
since the AC characteristics and pinout of the Am29PL160C are compatible with page mode
