Interface and connectivity ICs

Where should the EP (Exposed PAD) for the L9825 (Part Number) driver IC be connected?

There is no connection diagram for EP in the datasheet. We are using an LDO (Part Number: LT1121ACS8-5#PBF) to convert the supply voltage for the L9825 (+24V to +5V), and we are providing the L9825 with +5V as a power supply. LDOs have a common groun...

RSSI value not changing in BLE Mesh Network?

Hello ST,@EMECH​ ​I am using BLE_MeshLightingProvisiner sample project. We try to trace the RSSI value from the below mentioned function:: BLEMesh_NeighborRefreshedCallback(const MOBLEUINT8* bdAddr,                     MOBLEBOOL provisioned,         ...

How are the D+/D- lines connected when implementing the STUSB4500 for power purposes? In this case we want a Pi4 to act as a device, but power is handled separately.

STUSB4761 - I2C Device address missing in datasheet

Relating to STUSB4700 / 4710 datasheet I suggest the device address is the same as for 4700 with all adr pins set to 0.But no description in 4761 datasheet for I2C interface or register map.

How to emulate BlueNRG-2n with BlueNRG-2

Hi,We have a custom board with BlueNRG-2 and wants it to act as a co-processor so it can be controlled through SPI from another MCU (STM32L4R9).The BlueNRG-2 has been flashed with STSW-BNRG2N-V320 firmware through the bootloader interface.DIO0 SCKDIO...

What is the maximum SPI speed and MCU system clock which can be configured for using BlueNRG2-M2SP module with it

Hello, in the X-CUBE-BLE package this document STMicroelectronics.X-CUBE-BLE2_GettingStarted.pdf says the maximum SPI frequency could be 1Mbits/s . In high perf MCU running at SysClock >500 Mhz , is it possibe to interface BlueNRG2 with it?using Cl...

Partial framebuffer article and generated code missing details

Does your ULQ2803A have the standard eg; ULxxxx, IECxxxx ?

Hi ST expert,Our customer asked that your ULQ2803A have the standard ULxxxx , IECxxxx.But I could not catch it on your datasheet, also homepage and PRiSMA.Maybe your answer is NOTHING, so can you confirm it ?Thnaks, Yasuda / AVNET Japan

Inquiry about the production of other packages for product STULPI01A or STULPI01B.

Hello?​As title, I ask if a replacement package for the ULPI interface IC is planned to be manufactured.​Currently, the ULPI IC produced by ST is only a BGA package, but this BGA is too small in size and requires special specifications in PCB manufac...

Do ST offer any chips that would be able to support BLE 5.3/5.2 and use LE audio? My project has to have LE audio and i think BBLE 5.2 offers that. thank you
