Product details

25 MHz MSP430 CPUXV2 with integrated LCD and dual 24-bit ADC

The standout peripherals are an integrated LCD driver (segment count not specified here but part of the peripheral set) and dual data converters: eight 10-bit channels plus two 24-bit sigma-delta ADCs, which handle precision analog measurements without an external converter.

Flash and RAM sizing for the BOM

The 32 KB Flash (32K x 8) and 2K x 8 RAM define the firmware budget. For a typical smart-meter stack with a Modbus RTU library, LCD update routine, and a 24-bit ADC polling loop, 32 KB is comfortable but leaves limited room for over-the-air update staging. The Flash is field-reprogrammable via the internal bootloader or JTAG/SWD, so firmware updates are possible within the memory ceiling.

Package and mounting — 100-LQFP

The MSP430F6721IPZ comes in a 100-pin LQFP package (body 14x14 mm) with a 0.5 mm pitch. Surface-mount only; no through-hole option. The 100-LQFP footprint is common across the MSP430F6xx family, so a board layout for a sibling part may accept this device with no changes. The supplier device package is 100-LQFP (14x14).

The base product number is MSP430F6721.

Frequently asked questions

What is the flash memory size of MSP430F6721IPZ?

RAM is 2K x 8.

Does MSP430F6721IPZ have an LCD driver?

Yes, the MSP430F6721IPZ includes an integrated LCD driver as one of its peripherals, along with brown-out detect/reset, DMA, POR, PWM, and WDT.

What is the maximum clock speed of MSP430F6721IPZ?

The MSP430 CPUXV2 core in the MSP430F6721IPZ runs at 25 MHz. The internal oscillator is included, so no external crystal is required for basic operation, though an external clock source can be used for tighter timing.
