Product details
Overview
MSP430F1610IRTDT from Texas Instruments is a 16-bit ultralow-power mixed-signal microcontroller featuring 32KB+256B flash memory, 5KB RAM, dual 12-bit DACs, a 12-bit ADC with autoscan, two USARTs (UART/SPI/I²C), Timer_A3 and Timer_B7 with shadow registers, three-channel DMA, and hardware multiplier. It operates from 1.8 V to 3.6 V and targets battery-powered sensor systems and portable instrumentation.
For engineers reviewing the MSP430F1610IRTDT datasheet, MSP430F1610IRTDT pinout, MSP430F1610IRTDT application, or MSP430F1610IRTDT equivalent, key selection criteria include its 5KB RAM for large C-stack applications, 64-pin QFN (RTD) package, LPM4 standby current of 0.2 μA, dual USART support, and extended RAM addressing capability unique to the F161x series.
Technical Context
The MSP430F1610IRTDT implements a 16-bit RISC CPU with constant generators and seven addressing modes, enabling single-cycle register operations and high code efficiency. Its architecture integrates dedicated peripherals-including ADC12, DAC12, and DMA-directly into the memory-mapped address space for unified access via all instructions.
It supports six operating modes (AM, LPM0–LPM4), with wake-up from LPM4 in under 6 μs using the DCO oscillator. The device includes two independent USART modules: USART0 supports UART, SPI, and I²C; USART1 supports UART and SPI only-both are fully configurable via module enable and interrupt flag registers.

FAQ
What is the maximum operating frequency of the MSP430F1610IRTDT?
The MSP430F1610IRTDT supports a maximum CPU clock (MCLK) of 8 MHz derived from its digitally controlled oscillator (DCO). At 1 MHz and 2.2 V, active-mode current is specified at 330 μA. Frequency scaling is software-configurable via DCO calibration constants stored in information memory, enabling trade-offs between speed and power across operating conditions.
Does the MSP430F1610IRTDT support I²C communication?
Yes, the MSP430F1610IRTDT 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 includes dedicated I²C interrupt flags (I2CIFG) and control bits in the USPIEx registers, enabling standard master-mode operation with clock stretching and arbitration handling.
How much RAM is accessible in the MSP430F1610IRTDT, and how is it organized?
The MSP430F1610IRTDT provides 5KB of total RAM: 2KB mirrored at addresses 01100h–018FFh and 3KB extended at 01900h–024FFh. This architecture allows large static allocations in extended RAM while preserving fast-access mirrored regions for stack and critical variables-essential for deterministic real-time behavior in C-based firmware.
What development tools are compatible with the MSP430F1610IRTDT?
The MSP430F1610IRTDT is supported by TI's MSP-FET430UIF (USB JTAG emulator), MSP-GANG430 (production programmer), and Code Composer Studio IDE. Hardware debugging uses the standard 4-wire JTAG interface (TCK/TMS/TDI/TDO). The integrated Bootstrap Loader (BSL) also enables UART-based programming via P1.1 and P2.2, eliminating need for JTAG during field updates.
Is the MSP430F1610IRTDT pin-compatible with other MSP430F161x devices?
Yes, the MSP430F1610IRTDT shares identical 64-pin QFN (RTD) package pinout and electrical characteristics with MSP430F1611IRTDT and MSP430F1612IRTDT. All three support the same peripheral mappings, register layouts, and memory organization-enabling drop-in replacement for memory-scaling design iterations without PCB changes.
