The Texas Instruments MSP430F6459TPZR is a 16-bit MSP430 CPUXV2 microcontroller running at 20 MHz, with 512 KB Flash and 66 KB SRAM. It integrates an LCD controller, DMA, a 16-channel 12-bit ADC, and dual 12-bit DACs. The 100-LQFP package keeps rework manageable with a standard soldering iron.
20 MHz core and memory — what it means for the BOM
The 20 MHz CPUXV2 core handles real-time control loops and LCD segment refresh. 512 KB Flash and 66 KB SRAM support firmware, UI strings, and data buffering.
On-chip peripherals reduce external parts
The integrated LCD controller drives segmented displays directly, cutting the need for a separate driver IC. Brown-out detect and POR handle power-on sequencing internally. The 16-channel 12-bit ADC and dual 12-bit DAC cover sensor input and analog output loops — a single-chip solution for a data-acquisition front-end.
