PSoC™ 4 Forum Discussions
Hello Everyone. We have been using CY8C27443-24SXI for years and we have an out of state engineer who has done our programming but has passed away and we are in a situation. The above chip is out of stock until march 2022 it looks like. Can anyone recommend a substitute that we can drop in without modifying anything?
Thanks in advance!
Show LessHi! I'm seeing this issue on several PSoC 4200L devices where an OVT pin in digital hi-z mode, ie used as an input, gets "stuck" outputting something like 2.8 V after connecting it to a 5 V source unless pulled down fairly hard (10k external pull-down gets it back to 0 V; 47k and above does not).
As an example, this can be reproduced on a CY8CKIT-046 PSoC® 4 L-Series Pioneer Kit by connecting pin P6.0 to 5 V with a 47 k pull-down. After disconnecting thr 5 V source, the pin will be around 2.6 V and the current through the resistor around 0.07 mA.
Is this a known behaviour and does anyone have an explanation for it?
Show LessLast month I build some boards with 40pcs data code 1731 0887(only 5pcs works), and 10 pcs data code 2013 2600(all works)
Any difference from product side?
Show LessI would like to propose this part to the customer but the website does not have Datasheet.
please provide the datasheet of this part as below. Thanks.
Part Number: CY8C4147AZI-S453T (cypress.com) package 48QFP.
Show LessHello,
I have questions about default GPIO drive mode.
1. I think the default drive mode for all GPIOs at the factory shipment is High-Impedance Analog, is that correct?
2. In case of PSoC4000S, GPIOs other than Dedicated Analog Resources (LPCOMP) are recognized as not connecting analog, is this correct?
3. In case of PSoC4100S and PSoC4100S Plus, GPIOs other than Dedicated Analog Resources (LPCOMP and OPamps) are recognized as not connecting analog, is this correct?
I imagined from the block diagram below.
Best regards,

Hello,
Does anyone know of a programming/test socket for a 28 SSOP PSoC 4, specifically CY8C4124PVI-442. I see there are sockets out there, but I don't think this particular PSoC size fits them or is standard.
Thanks,
Show LessHi everyone,
I am new to this group, I need a help for programming CY8C4245axi-483.
Can I use CY8CKIT-049-42xx PSoC 4
For programming the external CY8C4245axi-483. If it is not useful. Please suggest me the suitable programmer.
Thank you in advance.

Hi,
I am testing the component Die temperature with the boad CY8CKIT-041-41XX, bur the temperature value is wrong: -30°C at 25°C ambient.
I am using your example code called CE195275 – Sequencing SAR ADC and Die
Temperature Sensor with PSoC 4.
Why is there this difference ?
Best regards

Show LessHello Team Cypress,
I am here to ask for a Cypress MCU in order to replace Microchip's ATSAMHA1E15A-B(32-pin QFN)
https://www.microchip.com/en-us/product/ATSAMHA1E15A-B
The MCU part, that we seek, shall
-have the automotive quality.
- be used for the step motor starter application for "active grille shutters"
- be used along with the LIN step motor gate driver from Infineon (see the blocks above).
- support LIN+SPI communication protocol (the MCU will run in LIN slave mode)
- have an equal or smaller packaging size with the products listed above preferably due to PCB size.
- have a relatively good delivery date in terms of logistics.
If you could suggest
specific model with the part number
from the Cypress automotive quality MCU
for the MCU part of the design block,
that would be really appreciated.
Thank you in advance.
Sincerely,
Ben
My team and I are looking for a suitable Cypress Automotive MCU part for the following applications and features needed.
One of my clients is considering to replace a MLX81315 Melexis with a Cypress MCU part.
Smart LIN driver IC for DC, stepper, BLDC motors (MLX81310/15) #Melexis
There are available candidates listed on the left side block of the diagram above,
but I am here to ask for advice if there is any automotive quality Cypress MCU part suggestion adequate for the job.
The MCU part, that we seek, shall
-have the automotive quality.
- be used for the step motor starter application for "active grille shutters" (which help the vehicle's aerodynamic design).
- be used along with the LIN step motor gate driver from Infineon (see the blocks above).
- support LIN+SPI communication protocol
- have an equal or smaller packaging size with the products listed above preferably due to PCB size.
(S9S08SL8F1MTJ (TSSOP-20) / ATSAMHA1E15A-B(32-pin QFN) )
- have a relatively good delivery date in terms of logistics.
If you could suggest us the Cypress automotive part that fits the MCU part of the block, that would be really appreciated.
Thank you in advance.
