Product details
Overview
MSP430F1611IRTDT from Texas Instruments is an ultralow-power 16-bit mixed-signal microcontroller featuring 48KB+256B flash memory, 10KB RAM, dual 12-bit DACs, a 12-bit ADC with autoscan, two 16-bit timers (Timer_A3 and Timer_B7), three-channel DMA, and dual USARTs supporting UART/SPI/I²C. It operates from 1.8 V to 3.6 V and targets battery-powered sensor systems and portable instrumentation.
For engineers reviewing the MSP430F1611IRTDT datasheet, MSP430F1611IRTDT pinout, MSP430F1611IRTDT application, or MSP430F1611IRTDT equivalent, key selection criteria include its 10KB RAM for large C-stack applications, Timer_B7 with seven capture/compare registers, RTD-package QFN-64 footprint, and dual USART support including I²C on USART0 - all validated for industrial control and handheld metering designs.
Technical Context
The MSP430F1611IRTDT implements a 16-bit RISC CPU with constant generators and seven addressing modes, enabling single-cycle register operations and high code efficiency. Its clock system integrates DCO, ACLK, SMCLK, and MCLK with programmable dividers and supports crystal oscillators XT1 (32.768 kHz) and XT2 (up to 8 MHz).
Peripherals are memory-mapped and fully accessible via standard instructions. The device uses a unified interrupt vector table (0xFFFE–0xFFE0), supports maskable/non-maskable interrupts across 16 sources, and includes JTAG/EEM for in-circuit debugging - with dedicated TCK/TMS/TDI/TDO pins and BSL serial programming via P1.1/P2.2.

FAQ
What is the maximum operating frequency of the MSP430F1611IRTDT?
The MSP430F1611IRTDT supports a maximum MCLK frequency of 8 MHz when using the XT2 oscillator (standard crystal up to 8 MHz). With the internal DCO, typical operation reaches 1 MHz in active mode, and the device guarantees full functionality across its 1.8 V–3.6 V supply range at that speed. The 125-ns instruction cycle time corresponds to 8 MHz operation.
Does the MSP430F1611IRTDT support hardware I²C communication?
Yes, the MSP430F1611IRTDT supports hardware I²C exclusively on USART0, using P3.1 (SDA) and P3.3 (SCL) pins. This implementation complies with the Philips I²C specification and supports standard-mode (100 kbps) and fast-mode (400 kbps) operation. USART1 does not provide I²C capability.
How much RAM is physically addressable in the MSP430F1611IRTDT?
The MSP430F1611IRTDT provides 10KB of total RAM, organized as 5KB base RAM (0x1100–0x24FF), 2KB mirrored RAM (0x1100–0x18FF), and 3KB extended RAM (0x1900–0x24FF). This architecture enables efficient stack growth and large data buffers while maintaining compatibility with standard MSP430 toolchains.
What development tools are recommended for the MSP430F1611IRTDT?
Texas Instruments recommends the MSP-FET430UIF (USB JTAG programmer/debugger) and MSP-TS430RTD target socket board for the RTD package. Code development is supported by MSP430Ware peripheral driver libraries and TI's Code Composer Studio IDE. The integrated Embedded Emulation Module (EEM) enables real-time breakpoints and register inspection.
Is the MSP430F1611IRTDT pin-compatible with other MSP430F161x devices in the RTD package?
Yes, the MSP430F1611IRTDT is pin-compatible with MSP430F1610IRTDT and MSP430F1612IRTDT in the 64-pin QFN (RTD) package. All share identical pin functions, electrical characteristics, and package dimensions - allowing firmware reuse and direct substitution within the same hardware design.
