What this 16-bit MCU brings to a metering or sensor design
It carries 128 KB of program Flash and 4K x 8 of RAM, but the standout feature is the analog front-end: three 24-bit sigma-delta ADCs alongside five 10-bit channels.
Texas Instruments lists the MSP430F6735IPNR as Obsolete.
The dual 24-bit ADC — the real selection driver
Three 24-bit sigma-delta ADCs and five 10-bit converters share the die. The 24-bit channels are the reason this MCU gets specified for revenue-grade energy metering and load-analysis applications where the ADC resolution directly determines measurement accuracy. The 10-bit channels handle auxiliary monitoring — temperature, voltage reference, or tamper detection — without tying up the precision path. If your design relies on that 24-bit front-end, the MSP430F6735IPNR is the part you need; a generic 16-bit MCU without the sigma-delta ADCs won't drop in.
Connectivity and peripheral set for system integration
The built-in LCD driver and PWM outputs reduce external component count in user-interface and control loops. Brown-out detect and POR are on-chip, so the supply supervision is handled without a separate reset IC.
