MSP430F6726IPNR — 16-bit MCU with integrated LCD and dual ADC
The Texas Instruments MSP430F6726IPNR is a 16-bit microcontroller built around the MSP430 CPUXV2 core, running at 25 MHz. It packs 128 KB of Flash program memory and 8 KB of RAM, with a 1.8 V to 3.6 V supply range and an industrial temperature grade of -40°C to 85°C. The standout feature is the dual ADC block — five 10-bit channels for fast sampling and two 24-bit sigma-delta channels for precision measurement — combined with an integrated LCD controller, DMA, and a full set of serial interfaces (I²C, SPI, UART, LIN, IrDA). This makes the part a natural fit for smart meters, instrumentation front-ends, and industrial sensor hubs where a single chip must handle both real-time control and high-resolution analog acquisition.
25 MHz core — timing budget for mixed-signal tasks
The 25 MHz clock rate on the MSP430 CPUXV2 core sets the timing closure for the LCD frame refresh, the 24-bit ADC conversion cycles, and the serial bus bit rates. At this speed, the DMA engine can move conversion results directly to RAM without CPU intervention, keeping the core free for higher-level protocol handling. For a metering design that needs to sample two voltage and current channels at 24-bit resolution while updating a segment LCD every 10 ms, the 25 MHz headroom is sufficient — no external ADC or display driver IC required.
Dual ADC: 5×10b + 2×24b — one chip does the analog front-end
The MSP430F6726IPNR integrates a 10-bit SAR ADC with five channels and a 24-bit sigma-delta ADC with two channels.
Lifecycle status — EOL, sourced to order
The MSP430F6726IPNR carries an end-of-life (EOL) status. New supply is available through independent distribution.
