Product details

Mixed-signal MCU with integrated LCD drive

It packs 128 KB of program Flash and 4K x 8 of RAM, with a rich set of mixed-signal peripherals including a 5-channel 10-bit ADC and a separate 2-channel 24-bit sigma-delta ADC for precision measurement.

Package and mounting

The 128 KB Flash is self-timed and supports byte/word writes, which simplifies firmware updates over the UART or SPI bootloader. The 4K x 8 RAM is modest — enough for moderate data logging or a small RTOS stack, but a heavy frame buffer for the LCD will eat into it fast. The two 24-bit sigma-delta ADCs are the standout feature here: they give you the resolution to read strain gauges, thermocouples, or current shunts directly without an external amplifier, though the conversion rate is slow compared to the 10-bit SAR ADC. Brown-out detect and POR are on-chip, so a simple RC reset is usually sufficient.

Package, supply, and temperature grade

Housed in an 80-pin LQFP with a 12x12 mm body. Surface-mount only — no through-hole option.

Frequently asked questions

What is the difference between MSP430F6725AIPN and MSP430F6724AIPN?

The primary difference is Flash memory size: the MSP430F6725AIPN has 128 KB of program Flash, while the MSP430F6724AIPN has 96 KB. Both share the same 80-LQFP package, 25 MHz core speed, 4K x 8 RAM, and peripheral set including the dual ADCs and LCD driver. The 6725 is the higher-density option for firmware that needs the extra 32 KB.

What are the alternatives to MSP430F6725AIPN from other manufacturers?

Direct pin-compatible alternatives from other manufacturers are not common for the MSP430F6xx series due to TI's proprietary CPUXV2 core and integrated LCD controller. For similar mixed-signal capability with an LCD driver, Renesas offers the RL78/L1A series and Microchip has the PIC24F LCD family, but these require a board redesign and firmware port. Within TI's own MSP430 family, the MSP430F6725AIPN is the 128 KB Flash variant; the MSP430F6724AIPN (96 KB) and MSP430F6723AIPN (64 KB) are drop-in alternatives with less memory.
