Product details
Overview
MSP430F169IPMR from Texas Instruments is an ultralow-power 16-bit mixed-signal microcontroller with 60KB+256B flash memory, 2KB RAM, dual 12-bit DACs, 12-bit ADC with autoscan, two USARTs (UART/SPI/I²C), and seven-capture/compare Timer_B. It operates from 1.8 V to 3.6 V and targets battery-powered sensor nodes and portable instrumentation.
For engineers reviewing the MSP430F169IPMR datasheet, MSP430F169IPMR pinout, MSP430F169IPMR application, or MSP430F169IPMR equivalent, key selection criteria include flash/RAM size, dual USART support, 7-channel Timer_B capability, DAC synchronization, and QFP-64 package compatibility for industrial control and metering designs.
Technical Context
The MSP430F169IPMR implements a 16-bit RISC CPU with constant generators and 125-ns instruction cycle time, enabling high code efficiency in power-constrained environments. Its architecture integrates three-channel DMA, hardware multiplier, and programmable clock system with DCO wake-up in under 6 μs from standby mode.
It features two independent serial interfaces: USART0 supports UART, SPI, and I²C modes; USART1 supports UART and SPI only. The 12-bit ADC includes internal reference, sample-and-hold, and autoscan across eight analog inputs, while dual 12-bit DACs provide synchronized voltage outputs on P6.6 and P6.7.

FAQ
What is the maximum clock frequency supported by the MSP430F169IPMR?
The MSP430F169IPMR supports a maximum CPU clock frequency of 8 MHz using the internal digitally controlled oscillator (DCO). External crystal oscillators (XT1 and XT2) can operate up to 4 MHz and 8 MHz respectively, with the DCO tunable across multiple ranges to meet precise timing requirements in real-time applications. This allows the MSP430F169IPMR to balance performance and power consumption dynamically.
Does the MSP430F169IPMR support I²C communication?
Yes, the MSP430F169IPMR 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 MSP430F169IPMR includes dedicated I²C interrupt flags and control bits in its register map, enabling robust master/slave operation with clock stretching and arbitration handling.
How many analog input channels does the MSP430F169IPMR ADC support?
The MSP430F169IPMR integrates a 12-bit ADC12 module with eight selectable analog input channels (A0–A7), accessible via P6.0 through P6.7. The ADC supports autoscan mode to sequentially convert all enabled channels without CPU intervention, and includes internal reference voltage (2.5 V), sample-and-hold, and configurable conversion timing - all confirmed in the SLAS368G datasheet for this exact part number.
Is the MSP430F169IPMR pin-compatible with other devices in the MSP430F16x family?
Yes, the MSP430F169IPMR is pin-compatible with all 64-pin QFP (PM) variants in the MSP430F16x family, including MSP430F167IPMR and MSP430F168IPMR. All share identical pin functions, electrical characteristics, and package dimensions, enabling direct substitution in existing PCB layouts when flash/RAM requirements align with the target application.
What development tools are recommended for programming the MSP430F169IPMR?
Texas Instruments recommends the MSP-FET430UIF (USB JTAG emulator) and MSP-TS430PM64 (target socket board for PM package) for debugging and programming the MSP430F169IPMR. The device also supports UART-based bootloader (BSL) programming via P1.1 and P2.2, eliminating need for external hardware during field updates - a capability fully documented for the MSP430F169IPMR in SLAU049 and SLAS368G.
