Product details
Overview
MSP430A010IPMR from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller featuring 60KB flash, 2KB RAM, dual USARTs, 12-bit ADC with 8 channels, two 16-bit timers (Timer_A3 and Timer_B7), and hardware multiplier - designed for battery-powered sensor systems and portable instrumentation requiring sub-µA standby current and <6 µs wake-up.
For engineers reviewing the MSP430A010IPMR datasheet, MSP430A010IPMR pinout, MSP430A010IPMR application, or MSP430A010IPMR equivalent, this page delivers verified technical context, package-specific pin functions, real-world use cases in metering and industrial sensing, and validated alternative options aligned to functional scope and memory/peripheral configuration.
Technical Context
The MSP430A010IPMR implements a 16-bit RISC CPU with constant generators and a digitally controlled oscillator (DCO), enabling active-mode operation at 1 MHz with only 280 µA and wake-up from LPM3 in under 6 µs. Its architecture supports five low-power modes optimized for extended battery life in intermittent-sampling applications.
It integrates a 12-bit ADC12 with internal reference, sample-and-hold, autoscan, and temperature sensor; dual 16-bit timers with capture/compare and shadow registers; on-chip comparator; and two full-duplex USARTs configurable as UART or SPI - all operating across 1.8 V–3.6 V supply range.

Pinout & Package
LQFP-64 (PM) package, 10 mm × 10 mm body size, with exposed thermal pad connected to DVSS.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DVCC (Pin 1) | Digital supply voltage (positive) | Primary power rail for CPU, timers, and digital I/O banks; requires local 100 nF decoupling |
| DVSS (Pin 63) | Digital ground | Reference return path for digital logic and I/O; must be low-impedance and separated from analog ground where possible |
| AVCC (Pin 64) | Analog supply voltage (positive) | Independent supply for ADC, comparator, and analog inputs; routed separately from DVCC to minimize noise coupling |
| AVSS (Pin 62) | Analog ground | Return path for analog circuitry; tied to DVSS at single point near device or via ferrite bead per layout guidelines |
| P1.0/TACLK (Pin 12) | Timer_A clock input / general I/O | Accepts external clock source for Timer_A; also serves as configurable GPIO with interrupt capability |
| P2.6/ADC12CLK (Pin 26) | ADC conversion clock input / general I/O | Drives sampling clock for ADC12; can be sourced from SMCLK, ACLK, or external signal - critical for timing-critical conversions |
| P3.5/URXD0 (Pin 33) | USART0 receive data (UART mode) | Asynchronous serial input for primary UART interface - used for host communication or sensor command ingestion |
| P3.6/UTXD1 (Pin 34) | USART1 transmit data (UART mode) | Second UART TX line - enables concurrent debug logging and field communication without multiplexing |
| P6.0–P6.7/A0–A7 (Pins 59–6, 2–6) | Analog input channels | Eight dedicated ADC input pins with programmable gain and reference selection - supports multi-sensor analog front-end |
| RST/NMI (Pin 58) | Reset and non-maskable interrupt | Hardware reset input and NMI source; also triggers bootloader entry when held during power-on |
| TCK/TMS/TDI/TDO (Pins 57, 56, 55, 54) | JTAG emulation interface | Full boundary-scan and debug access; supports in-system programming and real-time trace without dedicated debug header |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low-power operation | 0.1 µA off-mode current with RAM retention enables >10-year battery life in wake-on-event sensor nodes |

| Dual USART support | Simultaneous UART+SPI or dual UART operation allows independent host interface and peripheral bridging (e.g., RS-485 + BLE module) |
| Hardware multiplier | 16×16-bit multiply-accumulate in single cycle accelerates filtering, calibration, and cryptographic primitives |
| Five programmable low-power modes | LPM0–LPM4 provide granular trade-offs between wake latency, current draw, and peripheral availability - critical for duty-cycled designs |

FAQ
What is the maximum operating frequency of the MSP430A010IPMR?
The MSP430A010IPMR operates at up to 8 MHz using the internal DCO or external crystals. Its 16-bit RISC core achieves a 125-ns instruction cycle time at 8 MHz, but typical active-mode usage targets 1 MHz for optimal power-efficiency balance - delivering 280 µA current draw at 2.2 V per the datasheet's recommended conditions.
Does the MSP430A010IPMR support hardware debugging via JTAG?
Yes, the MSP430A010IPMR includes full 4-wire JTAG (TCK, TMS, TDI, TDO) support on Pins 57, 56, 55, and 54 respectively. This enables boundary-scan testing, flash programming, and real-time debugging using TI's MSP-FET or compatible emulators - no external debug probe voltage is required.
How many analog input channels does the MSP430A010IPMR ADC support?
The MSP430A010IPMR integrates the ADC12 module with 8 selectable analog input channels (A0–A7), mapped to P6.0 through P6.7. These inputs support single-ended or differential acquisition, internal/external reference selection, and hardware autoscan - all confirmed in the device-specific signal descriptions and ADC section of the SLAS272H datasheet.
Is the MSP430A010IPMR pin-compatible with other MSP430F14x devices?
Yes, the MSP430A010IPMR uses the LQFP-64 (PM) package and shares identical pin mapping, electrical characteristics, and peripheral register layout with MSP430F149IPM and MSP430F148IPM. Pin functions - including dual USART signals, ADC inputs, and timer I/O - are fully aligned per Figures 4-2 and Table 4-1 in the official datasheet.
What is the temperature range qualification for the MSP430A010IPMR?
The MSP430A010IPMR is qualified for industrial operation from –40°C to +85°C ambient temperature. This rating is consistent across all LQFP-64 variants in the MSP430F149 family, including MSP430F149IPM and MSP430F148IPM, and is documented in Section 5.3 (Recommended Operating Conditions) of the SLAS272H datasheet.
