Texas Instruments MSP430F2013IRSAT

Overview

MSP430F2013IRSAT 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_A with two capture/compare registers - deployed in battery-powered sensor front ends and portable measurement systems.

For engineers reviewing the MSP430F2013IRSAT datasheet, MSP430F2013IRSAT pinout, MSP430F2013IRSAT application, or MSP430F2013IRSAT equivalent, key selection criteria include its -40°C to 85°C industrial temperature rating, 14-pin TSSOP (PW) package, 1.8–3.6 V supply range, sub-1 µs wake-up from LPM4, and integrated analog signal chain for precision low-power sensing.

Technical Context

The MSP430F2013IRSAT implements a 16-bit RISC CPU with constant generators and seven addressing modes, executing instructions in one CPU clock cycle (62.5 ns at 16 MHz). Its basic clock module integrates a digitally controlled oscillator (DCO) calibrated to ±1% at 1, 8, 12, and 16 MHz, plus support for 32-kHz crystal and internal low-frequency oscillators.

It features a dedicated SD16_A 16-bit sigma-delta ADC with differential input pairs (A0±, A1±, A2±, A3±), programmable gain amplifier, internal 1.2-V reference, and oversampling capability - all operating under ultra-low active current (220 µA at 1 MHz, 2.2 V) and standby current (0.5 µA).

FAQ

What is the maximum operating frequency of the MSP430F2013IRSAT's DCO oscillator?

The MSP430F2013IRSAT's digitally controlled oscillator (DCO) is factory-calibrated to operate at up to 16 MHz with ±1% accuracy across voltage and temperature. This frequency is achieved using calibration constants stored in flash information memory segment A (CALBC1_16MHZ/CALDCO_16MHZ), enabling reliable high-speed operation without an external crystal. The MSP430F2013IRSAT supports this full 16-MHz capability in active mode while maintaining ultra-low power consumption.

Does the MSP430F2013IRSAT support hardware UART communication?

No, the MSP430F2013IRSAT does not include a dedicated UART peripheral. It features a Universal Serial Interface (USI) module that supports hardware SPI and I²C protocols only. UART functionality must be implemented in software (bit-banged) using GPIO and Timer_A - which increases CPU load and timing sensitivity. For designs requiring native UART, alternatives like the MSP430G2553IPW28 should be considered, as the MSP430F2013IRSAT's USI cannot emulate UART at standard baud rates without significant firmware overhead.

What are the analog input configurations supported by the SD16_A module in the MSP430F2013IRSAT?

The SD16_A module in the MSP430F2013IRSAT supports four differential analog input pairs: A0±, A1±, A2±, and A3± - each with programmable gain amplifier (PGA) stages. It also provides internal 1.2-V reference and VREF input for external reference use. Inputs are routed exclusively through P1.x pins (P1.0 to P1.7), with no single-ended mode; all conversions require differential signaling. This architecture enables high-precision ratiometric measurements ideal for bridge sensors and low-noise applications, as confirmed in the SLAS491I datasheet section "Device Pinout, MSP430F20x3".

Can the MSP430F2013IRSAT operate from a 1.8-V supply while running the DCO at 16 MHz?

Yes, the MSP430F2013IRSAT is fully specified to operate at 16 MHz DCO frequency across its entire 1.8 V to 3.6 V supply range, as verified in the "Electrical Characteristics" section of SLAS491I. At 1.8 V, the DCO achieves 16 MHz with factory calibration data applied, though typical current consumption rises to ~320 µA in active mode. System design must ensure adequate decoupling and stable regulation, since marginal voltage droop may cause DCO instability - the MSP430F2013IRSAT's brownout detector (BOR) resets the device if VCC falls below the threshold.

Is the MSP430F2013IRSAT pin-compatible with other devices in the MSP430F20xx family?

Yes, the MSP430F2013IRSAT is pin-compatible with all 14-pin TSSOP (PW) variants in the MSP430F20xx family - including MSP430F2001IPW, MSP430F2011IPW, MSP430F2002IPW, MSP430F2012IPW, and MSP430F2003IPW - sharing identical pin numbering, functions, and electrical characteristics per package. However, peripheral differences (e.g., SD16_A vs. ADC10 vs. Comparator_A+) mean firmware and schematic design must match the specific variant's capabilities; the MSP430F2013IRSAT's pinout matches Table 4 ("Terminal Functions, MSP430F20x3") exactly.
