STW PDN 45075 "Status of IOXP is changed to discontinued" (45075_13133)


Availability of Control Unit IOXP is limited


Status of IOXP is changed to discontinued


The IOXP has been successfully at the market for numerous years.

Vendors of main components for the IOXP like output driver, CAN

transceiver and voltage regulator have issued PTNs (product

termination notification) and the same is expected to happen in the

near future for further components like the main controller.


The status of the IOXP will therefore be changed to “discontinued”.


At the same time STW announces the ESX.4ct as pin compatible

successor for the IOXP including a 32-bit AURIX controller as well as

additional features (see attached data sheet - changes in

comparison to IOXP are highlighted with red characters).


The delivery of ESX.4ct samples is scheduled for April 2023,

start of serial production (SSOP) is envisaged for Sept. 2023.


STW encourages you to transfer your applications to the ESX.4ct or

other current controllers. Our sales and support departments look

forward supporting you during this transition.


In case you require further IOXP devices within the scope of a last

time buy (LTB), please talk to your local sales representative too.


As a result of the additional acquisition costs for components (e.g.

material price, storage costs and component qualifying costs), the

price for the IOXP may increase.

Additionally, in future the warranty period may be limited by the

supply conditions of the component manufacturers.
