Product details
Overview
MSP430F1611IPMR from Texas Instruments is an ultralow-power 16-bit mixed-signal microcontroller with 48KB Flash, 10KB RAM, dual 12-bit DACs, 12-bit ADC with autoscan, two USARTs (UART/SPI/I²C), Timer_B7 with seven capture/compare registers, and DMA controller - deployed in portable sensor systems and battery-powered industrial control.
For engineers reviewing the MSP430F1611IPMR datasheet, MSP430F1611IPMR pinout, MSP430F1611IPMR application, or MSP430F1611IPMR equivalent, key selection criteria include RAM size for C-stack depth, dual USART support for multi-protocol communication, Timer_B7 channel count for complex PWM timing, and QFP-64 package compatibility with legacy PCB layouts.
Technical Context
The MSP430F1611IPMR 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 external crystal support (XT1/XT2).
It features two independent USART modules: USART0 supports UART, SPI, and I²C; USART1 supports UART and SPI only. The 12-bit ADC12 includes internal reference, sample-and-hold, and autoscan across eight channels, while dual DAC12 units provide synchronized voltage outputs with dedicated pins P6.6/DAC0 and P6.7/DAC1.

FAQ
What is the maximum operating frequency of the MSP430F1611IPMR?
The MSP430F1611IPMR operates with a digitally controlled oscillator (DCO) that supports up to 8 MHz at 3.3 V, delivering a 125-ns instruction cycle time. Its 16-bit RISC architecture ensures consistent performance across the 1.8 V to 3.6 V supply range, with timing validated per SLAS368G specifications. The MSP430F1611IPMR does not require external clocking for basic operation but supports XT1 (32 kHz watch crystal) and XT2 (up to 8 MHz standard crystal) for precision timing.
Does the MSP430F1611IPMR support I²C communication?
Yes, the MSP430F1611IPMR supports I²C communication exclusively through USART0, which can be configured in I²C mode using pins P3.1/SDA and P3.3/SCL. USART1 does not support I²C. The I²C implementation complies with standard protocol timing and includes interrupt-driven transaction handling. This capability is confirmed in the SLAS368G datasheet section "Serial Communication Interface (USART0)" and functional block diagram for MSP430F161x.
How much RAM is physically implemented in the MSP430F1611IPMR?
The MSP430F1611IPMR implements 10KB of total RAM, structured as 5KB base RAM (01100h–024FFh), 3KB extended RAM (01900h–024FFh), and 2KB mirrored RAM (01100h–018FFh). This architecture enables flexible memory mapping for stack growth, DMA buffers, and real-time data structures. All 10KB are accessible in active mode and retained in LPM4, as documented in the "memory organization, MSP430F161x" section of SLAS368G.
What development tools are compatible with the MSP430F1611IPMR?
The MSP430F1611IPMR is supported by TI's MSP-FET430UIF (USB JTAG emulator), MSP-FET430U64 (target board for PM package), and MSP-TS430PM64 (standalone target board). It also supports BSL programming via UART on P1.1 and P2.2. All tools interface with Code Composer Studio and IAR Embedded Workbench. These options are explicitly listed in the "DEVELOPMENT TOOL SUPPORT" section of SLAS368G for MSP430F161x devices.
Is the MSP430F1611IPMR pin-compatible with other MSP430F161x variants?
Yes, the MSP430F1611IPMR is pin-compatible with all MSP430F161x family members in the PM (64-pin QFP) and RTD (64-pin QFN) packages, including MSP430F1610IPMR and MSP430F1612IPMR. Pin functions, power terminals, JTAG, and peripheral mappings match exactly across the series, as confirmed by identical pin designation diagrams and terminal function tables in SLAS368G sections 5 and 8. This allows direct substitution in existing PCB designs.
