In all cases, however, readers are encouraged to verify that they have the latest information before finalizing their design. The following descriptions of Spansion data sheet designations are presented here to highlight their presence and definitions. Advance Information The Advance Information designation indicates that Spansion. is developing one or more specific products, but has not committed any design to production. Information presented in a document with this designation is likely to change, and in some cases, development on the product may discontinue. Spansion. therefore places the following conditions upon Advance Information content: “This document contains information on one or more products under development at Spansion. The information is intended to help you evaluate this product. Do not design in this product without contacting the factory. Spansion. reserves the right to change or discontinue work on this proposed product without notice.” Preliminary The Preliminary designation indicates that the product development has progressed such that a commitment to production has taken place. This designation covers several aspects of the product life cycle, including product qualification, initial production, and the subsequent phases in the manufacturing process that occur before full production is achieved. Changes to the technical specifications presented in a Preliminary document should be expected while keeping these aspects of production under consideration. Spansion places the following conditions upon Preliminary content: “This document states the current technical specifications regarding the Spansion product(s) described herein. The Preliminary status of this document indicates that product qualification has been completed, and that initial production has begun. Due to the phases of the manufacturing process that require maintaining efficiency and quality, this document may be revised by subsequent versions or modifications due to changes in technical specifications.” Combination Some data sheets contain a combination of products with different designations (Advance Information, Preliminary, or Full Production). This type of document distinguishes these products and their designations wherever necessary, typically on the first page, the ordering information page, and pages with the DC Characteristics table and the AC Erase and Program table (in the table notes). The disclaimer on the first page refers the reader to the notice on this page. Full Production (No Designation on Document) When a product has been in production for a period of time such that no changes or only nominal changes are expected, the Preliminary designation is removed from the data sheet. Nominal changes may include those affecting the number of ordering part numbers available, such as the addition or deletion of a speed option, temperature range, package type, or VIO range. Changes may also include those needed to clarify a description or to correct a typographical error or incorrect specification. Spansion. applies the following conditions to documents in this category: “This document states the current technical specifications regarding the Spansion product(s) described herein. Spansion. deems the products to have been in sufficient production volume such that subsequent versions of this document are not expected to change.

Protection Operation Sequence Over Current Protection (DD channel) The DD channel monitors the peak current of FET at any time during the operation. When the DD output becomes the over current state, the output voltage is decreased. Afterward, the timer operation is performed and the output stops after about 1 ms progress. When one of each DD channel stops operation by over current protection, all DD channels stop operation.

I2C Interface 23.1 Structure of I2C Interface 2 The I C interface executes the data communication in 1 byte (8-bit) units using two signal lines (bus), a SCL (serial clock line) and a SDA (serial data line). This bus is connected to multiple devices; master: device to generate the clock signal and to control the data transfer (CPU and so on) slave: device that an address is specified by a master. This IC is set as the slave and has no function to be the master. Each device is defined due to the communication direction as described below. transmitter: device to send data to bus receiver: device to receive data from bus The IC has the function both transmitter and receiver. SCL SDA transmitter receiver receiver maser slave1 transmitter slave2 The IC defines the followings; Write : data is transmitted from master and the IC receives data Read : The IC transmits data and master receives data. 23.2 Definition of Signal Lines SCL and SDA are connected to the power supply by the pull-up resistor. The output circuit is the open Drain output. When a bus is not used (waiting state), the open "H" is set changing the open Drain to the OFF state. Note: − 2 SCL and SDA pins adopt a different ESD protection system from standard I C specification because of ESD enhancement (see 25. I/O Pin Equivalent Circuit Diagram).

The receiver replies the ACK signal to show the data reception to a transmitter every time 1 byte (8-bit) of data is received. The ACK signal is sent in 9clk after sending data 8-bit matching to the SCL signal that the master generates. − A transmitter keeps SDA output "open H" in SCL9clk. − A receiver informs the data reception situation to a transmitter outputting the followings in SCL 9 clk; when data was received : SDA output "L" (ACK) when no data was received : SDA output "open H" (NACK) However, if the master is changed to the receiver, ACK is not replied after the last data reception because the bus keeps open stopping the data transmission to the slave transmitter. In this case, the slave transmitter opens the bus (open H) and is set to the stop condition reception waiting state from the master.

Layout Consider the points listed below and do the layout design. − Provide the ground plane as much as possible on the IC mounted face. GND and PGNDx provide the through hole proximal to GND and PGNDx pins of IC, and connect it with GND of internal layer. − Provide the power plane as much as possible to lower impedance of VCC. − Play the most attention to the loop composed of input capacitor (CPVCCx) and SWFET. Input capacitor (CPVCCx) connected with PVCCx should be placed close to the pin as much as possible to make the current loop as small as possible. Also connect the GND pin of the input capacitor with PGNDx. − Output capacitor (CVO3) connected with VO3 should be placed close to the pin as much as possible. Also connect the GND pin of the output capacitor with PGND3. − GND pins of the switching system parts provide the through hole at the proximal place, and connect it with GND of internal layer. − By-pass capacitor (CVREF, CAVCC) connected with VREF and AVCC should be placed close to the pin as much as possible. Also connect the GND pin of the by-pass capacitor with GND of internal layer in the proximal through-hole. − Pull the feedback line to be connected to the INx pin of the IC separately from near the output capacitor pin, whenever possible. Consider the line connected with INx pins to keep away from a switching system parts as much as possible because it is sensitive to the noise. − There is leaked magnetic flux around the inductor or backside of place equipped with inductor. Line and parts sensitive to noise should be considered to be placed away from the inductor (or backside of place equipped with inductor).
