The CY2305C and CY2309C are die replacement parts for CY2305 and CY2309.

The CY2309C is a low-cost 3.3 V zero delay buffer designed to distribute high speed clocks and is available in a 16-pin SOIC or TSSOP package. The CY2305C is an 8-pin version of the CY2309C. It accepts one reference input and drives out five low skew clocks. The -1H versions of each device operate up to 100–133 MHz frequencies and have higher drive than the -1 devices. All parts have on-chip phase locked loops (PLLs) which lock to an input clock on the REF pin. The PLL feedback is on-chip and is obtained from the CLKOUT pad.

Systems that rely on electronic subsystems for their functionality use EDRs to store information about system status as it evolves after a critical event occurs. A critical event typically stops the system from functioning.

An EDR, such as the one described in this application note, monitors communication among electronic subsystems (controller area network nodes) and records all or selected information. Moreover, an EDR can store information collected and processed locally from various sensors.

First of all , I just want to say thank you very much. I really appreciate your help. I've been scratching my head over this.

It definitely works. But one more question, When i go negative to about -2.49 , it becomes positive again and also when i reach about +2 positive volts , its kinda unstable like changing really fast. Do you know why ?

thanks a lot

Given that CAN is only a single component within the automotive system, developers need to be able to implement it with as few challenges as possible so they can focus on system-level functionality rather than struggle with peripheral configuration. This article will explore the CAN interface and discuss different ways of implementing, configuring, and tuning interfaces to facilitate simplified design.

Response:- PSoC Designer4.4 can be uninstalled using the PSoC Designer4.4 setup launcher. 

Follow the instructions with screen shot in the attached PSoCDesigner4.4Uninstallation.pdf.

Answer: In PSoC Designer and Creator, the LCD APIs uses only 7 bits, the description is as below:-

4 for data lines (D4-D7)

1 for Enable.

1 for Read/Write (RW)

D0-D3 lines of LCD should be grounded.

These pins must be connected consequently on a single port.

i.e. on a single port,  first 4 pins should be data lines, 5th pin as Enable, 6th as Register Select and 7th as Read/Write

Response: Refer the below table for maximum temperature and maximum time for soldering for Cypress Lead and Lead free parts.

Question: What is a PMDD? How to download the PMDD?

Response: Package Material Datasheets identify all substances contained in Cypress parts by package. PMDDs also confirm the absence of many banned substances. The information in the PMDDs will help Cypress customers plan for recycling or other "end of life" requirements. Go to www.cypress.com, Design Support >> Packaging link.  Select  “Package Material Declaration” in the Select Information type pull down list to access the PMDD documents for various packages.
