Texas Instruments MSP430F2012IPW

Overview

MSP430F2012IPW 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 operates from 1.8 V to 3.6 V, draws 220 µA at 1 MHz/2.2 V in active mode, and supports five power-saving modes - including sub-1-µs wake-up from standby - for battery-powered sensor systems.

Technical Context

The MSP430F2012IPW belongs to the MSP430F20x2 family and integrates a 16-bit RISC CPU with constant generators, digitally controlled oscillator (DCO) calibrated to ±1% at 1–16 MHz, and a basic clock module supporting ACLK (32 kHz crystal or internal LF), MCLK, and SMCLK. Its architecture enables single-cycle 62.5-ns instruction execution and ultra-fast wake-up from LPM3/LPM4.

It features a 10-bit, 200-ksps SAR ADC with internal reference, sample-and-hold, autoscan, and eight analog inputs (A0–A7); Universal Serial Interface (USI) configurable for SPI or I²C; brownout detector; and on-chip emulation via Spy-Bi-Wire. All peripherals are memory-mapped and accessible using full instruction set.

FAQ

What is the maximum operating frequency of the MSP430F2012IPW?

The MSP430F2012IPW supports an internal digitally controlled oscillator (DCO) factory-calibrated to four frequencies: 1 MHz, 8 MHz, 12 MHz, and 16 MHz - all within ±1% accuracy. It does not require an external crystal to achieve 16 MHz operation, making it suitable for applications needing fast wake-up and deterministic timing without added BOM cost.

Does the MSP430F2012IPW include a hardware UART?

No, the MSP430F2012IPW does not include a hardware UART. It features a Universal Serial Interface (USI) module that supports SPI and I²C protocols only. UART functionality must be implemented in software using Timer_A and GPIO pins - a common practice in ultra-low-power designs where asynchronous serial traffic is infrequent.

Can the MSP430F2012IPW operate from a single 2.0 V supply?

Yes, the MSP430F2012IPW operates across a supply range of 1.8 V to 3.6 V. At 2.0 V, it maintains full functionality including 10-bit ADC operation, USI communication, and Timer_A - with active current scaling linearly (e.g., ~200 µA at 1 MHz). This makes it ideal for single-cell lithium or two-cell alkaline battery systems.

How many analog input channels does the MSP430F2012IPW ADC support?

The MSP430F2012IPW integrates a 10-bit SAR ADC with eight selectable analog input channels (A0 through A7), plus dedicated VREF+ and VREF− pins. Channel selection is handled automatically in autoscan mode, allowing sequential conversion of up to eight sensors without CPU intervention - reducing firmware overhead and power consumption.

Is the MSP430F2012IPW pin-compatible with other devices in the MSP430F20xx family?

Yes, the MSP430F2012IPW in TSSOP-14 (PW) package shares identical pinout with MSP430F2001IPW, MSP430F2002IPW, MSP430F2003IPW, MSP430F2011IPW, MSP430F2013IPW, and all 'IN' and 'IRSA' variants. This allows direct substitution within the same package footprint when migrating between flash sizes or peripheral configurations - provided firmware accounts for feature differences.
