The following features require in the microcontroller

Flash memory size 4k max

Data RAM size 256 bytes

EEPROM size 64 bytes

Two 16-bits timers

I2C protocol supported

External clock supported

20 GPIO

If third timer can operate on 32 768 KHz External crystal then it is more preferable

which have this feature

no issue with SOP OR TSSOP 28 etc

Welcome, @jayden cai, to the community!

For example, you can use the STM8S003K3, but you can also choose other devices from the STM8 portfolio if you have additional requirements.

However, I would like to draw your attention to the fact that all STM8 have been set to NRND (Not Recommended for New Design) and will only be manufactured until 2032.

An alternative could be the Cortex-M0+ devices STM32L010F4 or STM32L010K4 (same device, just different package), which operate at 1.8-3.6V and also have 5V tolerant GPIOs (when operated as open drain without pull resistors).

Hope that helps?
