Product details
Overview
MSP430F2013TRSAR from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 2KB+256B flash, 128B RAM, a 16-bit Sigma-Delta ADC (SD16_A) with differential PGA inputs and internal reference, USI supporting SPI/I²C, and Timer_A2 with two capture/compare registers - deployed in battery-powered sensor front ends and portable measurement systems.
For engineers reviewing the MSP430F2013TRSAR datasheet, MSP430F2013TRSAR pinout, MSP430F2013TRSAR application, or MSP430F2013TRSAR equivalent, key selection criteria include its 16-bit SD16_A converter resolution, -40°C to 105°C extended temperature grade, TSSOP-14 package, Spy-Bi-Wire debug interface, and integrated brownout protection for robust operation in energy-constrained embedded designs.
Technical Context
The MSP430F2013TRSAR implements a 16-bit RISC CPU with constant generators and seven addressing modes, enabling single-cycle register operations at up to 16 MHz via its digitally controlled oscillator (DCO). Its clock system delivers ACLK, MCLK, and SMCLK from internal LF/DCO sources or external 32-kHz crystal/XIN.
It integrates SD16_A with 16-bit sigma-delta conversion, differential input pairs (A0±, A1±, A2±, A3±), programmable gain amplifier, and internal 1.2-V reference - all operating within the 1.8–3.6 V supply range. The USI module supports full-duplex SPI and I²C master/slave protocols using shared P1.4–P1.7 pins.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F2003TRSAR | 1KB+256B flash, no USI, comparator-based A/D (not SD16_A), same 14-pin TSSOP package | Lacks SPI/I²C and 16-bit sigma-delta conversion - suitable only for simpler analog threshold detection | Select only if design requires basic comparator functionality and no serial communication or high-resolution ADC |

FAQ
What is the maximum operating frequency of the MSP430F2013TRSAR's DCO?
The MSP430F2013TRSAR's digitally controlled oscillator (DCO) is factory-calibrated to operate at up to 16 MHz with ±1% accuracy across voltage and temperature. This enables full-speed execution of the 16-bit RISC core and supports high-resolution timing for SD16_A conversions and USI serial communication without requiring an external crystal.
Does the MSP430F2013TRSAR support hardware I²C communication?
Yes, the MSP430F2013TRSAR supports hardware I²C through its Universal Serial Interface (USI) module. Pins P1.6 (SCL) and P1.7 (SDA) provide dedicated I²C functionality, allowing the MSP430F2013TRSAR to act as master or slave in multi-device sensor networks without bit-banging overhead.
What is the purpose of the VREF pin (P1.3) on the MSP430F2013TRSAR?
On the MSP430F2013TRSAR, P1.3 functions as VREF - providing either an internal 1.2-V reference voltage output or accepting an external reference. It also serves as SD16_A negative input A1−, enabling ratiometric measurements critical for precision sensor interfaces like RTDs and bridge circuits.
Can the MSP430F2013TRSAR perform differential analog measurements?
Yes, the MSP430F2013TRSAR's SD16_A module supports true differential analog measurements across four independent channels: A0±, A1±, A2±, and A3±. Each pair maps to dedicated port pins (e.g., P1.0/P1.1 for A0±), eliminating the need for external instrumentation amplifiers in high-precision sensor front ends.
Is the MSP430F2013TRSAR pin-compatible with other devices in the MSP430F20xx family?
Yes, the MSP430F2013TRSAR shares identical pinout and package (14-pin TSSOP) with all MSP430F20xx variants including MSP430F2001–F2013 in PW packaging. This enables hardware reuse across designs - for example, upgrading from MSP430F2012TRSAR (10-bit ADC) to MSP430F2013TRSAR (16-bit SD16_A) without PCB revision.
