What is the difference between the model numbers with 1 and without 1? [Copy link]

For example, what is the difference between MSP430F6745A and MSP430F67451A? I checked the configurations and they are the same. Searching for MSP430F6745 shows 4 types, MSP430F6745A and MSP430F67451A, MSP430F6745 and MSP430F67451. The one with A should mean the revised version, so what does the one with 1 mean? Where can I find information on this issue? In addition, can the chips of multi-phase metering system-on-chip (SoC) such as MSP430F6745A be used as ordinary microcontrollers? I mainly use 4 24-bit ADCs to measure signal voltage. I checked some information and it is too clear. Please help me solve my doubts if you understand. Thank you.

Generally, BSL with 1 uses I2C, and BSL without 1 uses UART
