Product details
Overview
MSP430F1612IPMR from Texas Instruments is an ultralow-power 16-bit mixed-signal microcontroller featuring 55KB+256B flash memory, 5KB 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 nodes and portable instrumentation.
For engineers reviewing the MSP430F1612IPMR datasheet, MSP430F1612IPMR pinout, MSP430F1612IPMR application, or MSP430F1612IPMR equivalent, key selection criteria include its 55KB flash capacity, 5KB RAM with extended addressing, 64-pin QFP package, LPM4 standby current of 0.2 μA, and dual-USART support for concurrent serial protocols in space-constrained embedded designs.
Technical Context
The MSP430F1612IPMR 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 up to 8 MHz on XT2.
Peripherals are memory-mapped and fully interrupt-capable, including dedicated vector addresses for Timer_B7 (7 capture/compare registers), dual USARTs with independent UART/SPI modes, and ADC12 with internal reference and sample-and-hold - all accessible via unified 16-bit data/address buses without external glue logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPU with 16 general-purpose registers and constant generators; enables efficient C compilation and deterministic real-time execution. |
| Flash Memory | 55KB + 256B information memory; supports in-system programming via JTAG or BSL UART, enabling field firmware updates without hardware rework. |
| RAM | 5KB total (3KB extended + 2KB mirrored); supports large C stacks and real-time buffering for multi-threaded sensor fusion algorithms. |
| ADC | 12-bit SAR ADC with 8-channel autoscan, internal reference, and sample-and-hold; achieves <10 μs conversion time for high-speed analog monitoring. |
