PSoC™ 5, 3 & 1

I'm looking for a replacement for CY8C4245PVI-482 (datasheet), ideally with the same footprint/package (28-SSOP).

Maybe the CY8C4246PVI-DS402 (datasheet)?

CY8C4245PVI-482 CY8C4246PVI-DS402
ADC Resolution: 12 bit No ADC
24 I/O 21 I/O

CY8C4245PVI-482
CY8C4246PVI-DS402

 

Attributes Code 000-999: Code of feature set in the specific family. What does this mean? What features?

From the application's schematic, the pins colored on the left half are used:

CY8C4246PVI -482 vs -DS402.png

Is the DS402 compatible? (I cannot show the program.)

Hi @adamelli,

To add to your points, there will be no capsense support, no direct lcd drive and no adc in CY8C4246PVI-DS402. 

I observe that [P3.0 to P3.3] and [P0.1 to P0.3] are used. Since the particular functions of those pins are not revealed, you need to check if CY8C4246PVI-DS402 supports those functionalities.

[by considering all the alternative functions for the pins used in CY8C4245PVI-482, it seems possible to accommodate them in CY8C4246PVI-DS402]

Thanks for the quick reply!

P3.0 to P3.3 either uses GPIO or PWM. These pins seem like they would work. Although, I would guess P0.1 to P0.3 (red-green-blue-white light LEDs), which can be run off a DMX controller, has to have analog functionality.

Hi @adamelli ,

P3.0 to P3.3 either uses GPIO or PWM. >> Yes, there are resources available for PWM in CY8C4246PVI-DS402.

You can use analog pins for the analog functionalities. Below are the analog pins available for CY8C4246PVI-DS402.

Hello.

Be aware that P3.2 and P3.3 are also used for programming the device thru SWD signals.
