STM32L021D4P7 Which programmer to use for first time programming this IC

[Karpagamoorthy]

For first time programming this IC the reset pulse should go high to low for 4ms then it should comeback to high like a pulse which is programmer to use ?

STLINK-V3MINIE - will be suitable ?

Suggested for this requirement a programmer.

MPN : STM32L021D4P7

Hello,

Any genuine STLINK is suitable for any STM32 MCU including STLINK-V3MINIE.

So yes STLINK-V3MINIE is suitable for STM32L021D4P7

Can you kindly suggest genuine programmer for this part for first time empty chip programmer name ?

For a first-time programming setup, I’d also check the programmer’s reset and debug capabilities rather than choosing it only based on the MCU model. If the application needs a specific reset pulse sequence, it would be useful to confirm whether the ST-LINK-V3MINIE can handle that timing directly or whether the reset pulse needs to be generated separately by the target hardware. I’d also check the STM32L021D4P7 datasheet and programming connection before selecting the programmer.
