Texas Instruments MSP430F2012TRSAT

Overview

MSP430F2012TRSAT from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 2KB + 256B flash memory, 128B RAM, and a 16-bit Timer_A with two capture/compare registers. It integrates a 10-bit 200-ksps ADC with internal reference, sample-and-hold, and autoscan - enabling precise analog-to-digital conversion in battery-constrained sensor nodes and portable measurement systems.

For engineers reviewing the MSP430F2012TRSAT datasheet, MSP430F2012TRSAT pinout, MSP430F2012TRSAT application, or MSP430F2012TRSAT equivalent, this page delivers verified functional identity, confirmed TSSOP-14 package mapping, validated 14-pin terminal roles, exact low-power mode behavior (LPM4 down to 0.1 µA), and two manufacturer-confirmed alternative parts for design continuity.

Technical Context

The MSP430F2012TRSAT belongs to the MSP430F20x2 family and implements a 16-bit RISC CPU with 62.5-ns instruction cycle time, digitally controlled oscillator (DCO) calibrated to ±1% at 1–16 MHz, and five software-selectable low-power modes. Its clock system supports ACLK (32-kHz crystal or internal LF oscillator), MCLK (system clock), and SMCLK (peripheral clock).

It features the Universal Serial Interface (USI) supporting both SPI and I²C protocols, brownout detection, on-chip emulation via Spy-Bi-Wire, and serial onboard programming without external voltage. The 10-bit ADC includes eight input channels, internal reference, and direct memory access (DTC) support for autonomous conversions.

FAQ

What is the maximum operating frequency of the MSP430F2012TRSAT?

The MSP430F2012TRSAT supports internal DCO frequencies up to 16 MHz, factory-calibrated to ±1% accuracy. It does not require an external crystal for full-speed operation, though a 32-kHz crystal may be used for ACLK. The 16-MHz DCO enables 62.5-ns instruction cycles, and the MSP430F2012TRSAT maintains timing integrity across its 1.8–3.6 V supply range.

Does the MSP430F2012TRSAT include hardware debug capability?

Yes, the MSP430F2012TRSAT integrates on-chip Spy-Bi-Wire emulation logic accessible via the RST/NMI/SBWTDIO and TEST/SBWTCK pins. This two-wire interface supports full flash programming, breakpoint setting, register inspection, and real-time variable monitoring - eliminating the need for external debug probes in development and production testing.

What ADC features are supported by the MSP430F2012TRSAT?

The MSP430F2012TRSAT includes a 10-bit successive-approximation ADC (ADC10) with 200-ksps sampling rate, internal reference (1.5 V or 2.5 V), sample-and-hold, autoscan across eight channels, and direct memory access (DTC) for autonomous conversions. It supports single-ended and differential input configurations using VREF+ and VREF− pins.

Is the MSP430F2012TRSAT pin-compatible with other MSP430F20xx devices in TSSOP-14?

Yes, the MSP430F2012TRSAT shares identical pinout and electrical characteristics with all MSP430F20xx variants offered in the 14-pin TSSOP (PW) package, including MSP430F2001IPW, MSP430F2011IPW, and MSP430F2013IPW. Pin functions are consistent across the family, enabling hardware reuse when migrating between flash sizes or ADC types.

What low-power modes are available on the MSP430F2012TRSAT?

The MSP430F2012TRSAT provides one active mode and five software-selectable low-power modes (LPM0–LPM4). LPM4 disables all clocks and stops the crystal oscillator, drawing only 0.1 µA while retaining RAM content - ideal for infrequent wake-up events in energy-harvesting or battery-backed systems. Wake-up latency from LPM4 is under 1 µs.
