Product details
Overview
MSP430F1611IPM from Texas Instruments is an ultralow-power 16-bit mixed-signal microcontroller with 48KB+256B flash memory, 10KB RAM, dual 12-bit DACs, 12-bit ADC with autoscan, two USARTs (UART/SPI/I²C), and Timer_B7 with seven capture/compare registers. It operates from 1.8 V to 3.6 V and supports sub-6-μs wake-up from standby mode - ideal for battery-powered sensor nodes and portable instrumentation.
For engineers reviewing the MSP430F1611IPM datasheet, MSP430F1611IPM pinout, MSP430F1611IPM application, or MSP430F1611IPM equivalent, key selection criteria include RAM size (10KB), dual USART support (USART0 + USART1), Timer_B7 channel count (7 CCRs), extended addressing capability, and QFP-64 package compatibility with industrial PCB layouts.
Technical Context
The MSP430F1611IPM implements a 16-bit RISC CPU with constant generators and 16 general-purpose registers, enabling single-cycle register operations and high code efficiency. Its architecture integrates three-channel DMA, hardware multiplier (MPY/MAC), and dedicated peripherals including ADC12 with internal reference and sample-and-hold.
It features dual clock domains (ACLK, SMCLK, MCLK) driven by DCO, XT1, and XT2 oscillators, supporting flexible low-power operation across five LPMs. The device includes JTAG-based debugging via Embedded Emulation Module (EEM), programmable SVS voltage monitoring, and BSL-enabled UART in-system programming without external voltage.

FAQ
What is the maximum operating frequency of the MSP430F1611IPM?
The MSP430F1611IPM supports a maximum CPU clock frequency of 8 MHz using the digitally controlled oscillator (DCO). When externally clocked via XT2, it achieves up to 8 MHz with standard crystals. The 125-ns instruction cycle time corresponds to this 8-MHz operation, enabling deterministic real-time response in time-critical firmware.
Does the MSP430F1611IPM support I²C communication?
Yes, the MSP430F1611IPM 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 hardware implements standard I²C master functionality with clock stretching and arbitration support per the MSP430x1xx Family User's Guide.
How much RAM is physically implemented in the MSP430F1611IPM?
The MSP430F1611IPM contains 10KB of on-chip RAM, organized as 5KB base RAM (01100h–024FFh), 3KB extended RAM (01900h–024FFh), and 2KB mirrored RAM (01100h–018FFh). This architecture enables efficient stack growth, large data buffers, and memory-mapped peripheral access without external SRAM.
Can the MSP430F1611IPM generate simultaneous PWM signals on multiple pins?
Yes, the MSP430F1611IPM can generate simultaneous PWM signals using Timer_A3 (3 output channels) and Timer_B7 (7 output channels), for up to 10 independent PWM outputs. Each CCR supports edge-aligned or center-aligned modes, and outputs can be synchronized via TBCTL.SYNC bit to eliminate phase jitter across channels.
Is the MSP430F1611IPM pin-compatible with other devices in the MSP430F161x family?
Yes, the MSP430F1611IPM is pin-compatible with MSP430F1610IPM and MSP430F1612IPM in the 64-pin QFP (PM) package. All share identical pin functions, electrical characteristics, and memory-mapped peripheral registers - allowing drop-in replacement when flash/RAM requirements align with target firmware constraints.
