Product details

What this 16-bit MCU brings to a low-power BOM

The 10 general-purpose I/O pins, internal oscillator, and integrated peripherals (brown-out detect, POR, PWM, watchdog timer) mean it can handle a basic supervisory or sequencing role without external glue logic.

Memory budget — 2 KB Flash, 128 bytes RAM

The 2 KB Flash (2K x 8) is the entire non-volatile code and constant-data space. That is enough for a bootloader plus a small state machine, but not for a full protocol stack or lookup table. The 128 x 8 SRAM (128 bytes) sets a tight ceiling on stack depth and interrupt nesting — a single deep ISR chain or a moderate-sized local array can overflow it. Any firmware project targeting this part needs a memory map drawn before the first line of C.

Supply and temperature range

Brown-out detection and POR are on-chip, which simplifies the reset circuit and improves reliability in noisy or battery-powered environments.

Housed in a 14-TSSOP (4.40 mm body width) with a surface-mount footprint. It is a single-row package with no exposed thermal pad, so all heat dissipates through the leads and the PCB copper. The 14-pin count limits I/O to 10, but that is sufficient for a UART, a couple of ADC inputs (if the part had ADC — this variant does not), or a few GPIOs for LED/switch control.

TI lists the MSP430G2201IPW14R as Active. For a production BOM, this part carries no imminent supply risk.

Frequently asked questions

Does MSP430G2201IPW14R have PWM and brown-out detection?

Yes. The peripheral set includes a brown-out detect/reset circuit, a power-on reset (POR), a PWM timer, and a watchdog timer (WDT) — all integrated on-chip. No external supervisor IC is needed for basic reset management.

Is MSP430G2201IPW14R RoHS compliant and lead-free?

The 14-TSSOP package (MSP430G2201IPW14R) is TI's standard Green/RoHS-compliant suffix. The 'R' at the end of the order code indicates tape-and-reel packaging, not a lead-free flag, but TI's MSP430G2xx devices in this package are manufactured with NiPdAu (or similar) lead-free plating per RoHS requirements.

What is the closest pin-compatible alternative to MSP430G2201IPW14R in this component family?

Within the MSP430G2xx series, the MSP430G2201 is a base part number with 2 KB Flash and 128 B RAM. A pin-compatible step-up would be the MSP430G2231 (same 14-TSSOP package, same pinout) which adds a 10-bit ADC and a larger Flash option (2 KB or 4 KB depending on variant). Any swap requires checking the exact memory and peripheral differences against the firmware requirements.

What is MSP430G2201IPW14R's listed speed (16 MHz) on this component line?

The MSP430 CPU16 core is rated for 16 MHz maximum operating frequency. At that speed, the internal Flash requires zero wait states (the MSP430G2xx architecture uses a single-cycle Flash controller up to 16 MHz). The internal oscillator can be calibrated to ±1% accuracy, which is sufficient for UART baud-rate generation without an external crystal.
