Product details
Overview
MSP430F2013IN from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 2KB+256B flash memory, 128B RAM, and a 16-bit Sigma-Delta A/D converter with differential PGA inputs and internal reference. It operates from 1.8 V to 3.6 V and supports five power-saving modes, enabling sub-1 µs wake-up from standby-ideal for battery-powered sensor front ends and portable measurement systems.
For engineers reviewing the MSP430F2013IN datasheet, MSP430F2013IN pinout, MSP430F2013IN application, or MSP430F2013IN equivalent, key selection criteria include its integrated SD16_A ADC resolution (16-bit), USI interface (SPI/I²C), TSSOP-14/PDIP-14 package compatibility, and -40°C to +85°C industrial temperature range.
Technical Context
The MSP430F2013IN implements a 16-bit RISC CPU with constant generators and seven addressing modes, delivering 62.5-ns instruction cycle time at up to 16 MHz via calibrated DCO. Its basic clock module provides ACLK (from 32-kHz crystal or internal LF oscillator), MCLK (system clock), and SMCLK (peripheral clock).
It integrates Timer_A2 with two capture/compare registers, Spy-Bi-Wire on-chip emulation, brownout protection, and a universal serial interface (USI) supporting both SPI and I²C protocols-enabling direct interfacing with sensors, EEPROMs, and digital transducers without external level-shifting or protocol translation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F2012IN | 10-bit 200-ksps ADC instead of 16-bit SD16_A; identical flash/RAM, USI, and power specs | Better suited for cost-sensitive applications requiring <12-bit resolution and higher sampling rate | Select MSP430F2012IN when 10-bit ADC speed (200 ksps) outweighs resolution needs and system budget is constrained |

FAQ
What is the maximum operating frequency of the MSP430F2013IN?
The MSP430F2013IN supports a maximum system clock (MCLK) frequency of 16 MHz, achieved via its factory-calibrated digitally controlled oscillator (DCO) with four trim points (1/8/12/16 MHz) accurate to ±1%. This enables 62.5-ns instruction cycle time without requiring an external crystal, though a 32-kHz watch crystal may be used for ACLK.
Does the MSP430F2013IN support hardware SPI and I²C simultaneously?
No-the MSP430F2013IN features a single Universal Serial Interface (USI) module that can be configured for either SPI or I²C operation, but not both concurrently. The USI uses shared pins (P1.6/P1.7/P1.5) and requires software reconfiguration to switch between protocols, making it suitable for systems communicating with one type of peripheral at a time.
What analog input configurations does the SD16_A ADC support on the MSP430F2013IN?
The SD16_A ADC on the MSP430F2013IN supports true differential input pairs (e.g., A0+/A0−, A1+/A1−, A2+/A2−, A3+/A3−), pseudo-differential mode using internal VREF, and single-ended acquisition relative to AVSS. Input ranges are programmable via PGA gain settings (1× to 16×), and the internal 1.2-V reference is available on P1.3 for ratiometric measurements.
Can the MSP430F2013IN operate from a single 1.8-V supply without external regulators?
Yes-the MSP430F2013IN is fully specified to operate across 1.8 V to 3.6 V, with all peripherals-including the SD16_A ADC, USI, and Flash memory-functional at 1.8 V. Its ultra-low active and standby currents (220 µA at 1 MHz, 0.5 µA standby) make it ideal for direct coin-cell or single Li-ion battery operation without intermediate regulation.
How many I/O pins are available on the MSP430F2013IN in the PDIP-14 package?
The MSP430F2013IN in the 14-pin PDIP (N) package provides 10 usable I/O pins: P1.0 through P1.7 (8 pins), plus P2.6 and P2.7. Pins RST/NMI/SBWTDIO and TEST/SBWTCK are multifunctional (debug + reset), while VCC and VSS are power terminals-not general-purpose I/O.
