microprocessor selection

Jigar,

Thanks for asking.

AM3352AZCZ60 has all the functionalities you are looking for and if you consider that performance of Cortex-A8 is higher than ARM9, you probably can use AM3352AZCZ30 (300MHz) without issues.

AM3352 has cheaper development tools, more robust software offering and more support and price wise, they are very close. For quotes, please work with your distributor or TI sales representative.

Thank you sir for your replay.

Sir in power supply domain, can we use linear regulators (1.2V,1.8V,3.3V) instead of power management IC (switching regulators)?

Jigar,

We recommend the use of a PMIC because with it you can take advantage of dynamic voltage control reducing power comsuption and it will provide the correct power on sequence.

thanks sir

we will go for PMIC.

Sir what is the life cycle of AM1808BZCED4 & AM3352ZCE27 ?

Jigar,

We have no plans to obsolete both parts, AM335x is the newest Sitara ARM MPU family and we see strong momentum.
