Product details

16 MHz MSP430 core with AEC-Q100 — the automotive sensor-node MCU

512-byte Flash and 128-byte RAM — what fits in that budget

With 512 bytes of Flash and 128 bytes of RAM, this is not a general-purpose MCU for complex firmware stacks. The code space fits a single sensor readout loop with a few calibration constants, a LIN or PWM output routine, or a simple debounced switch-to-CAN gateway. The RAM holds a handful of variables and a small stack — any buffering beyond a few bytes requires external serial EEPROM or careful allocation. For designs that need more headroom, the MSP430G2 family offers pin-compatible parts with up to 8 KB Flash and 512 B RAM in the same 14-TSSOP footprint.

Supply range and oscillator — single-rail simplicity

For RTC or CAN applications, an external low-frequency crystal can be connected to the available I/O reconfigured as timer inputs.

For production programs that require a second-source or higher-density option, the MSP430G2 family includes multiple Flash and RAM tiers in the same 14-TSSOP package — the MSP430G2201 (2 KB Flash) or MSP430G2401 (8 KB Flash) are drop-in replacements with the same pinout and peripheral set, differing only in memory size.

Frequently asked questions

Can MSP430G2001IPW4RQ1 be used instead of MSP430G2001IPW4?

Yes — the MSP430G2001IPW4RQ1 is the Tape & Reel packaged variant of the MSP430G2001IPW4 (tube). The die, firmware, and pinout are identical. The only difference is the shipping medium: T&R for automated assembly lines versus tube for hand-load or low-volume builds.

What is MSP430G2001IPW4RQ1's listed speed?

The core processor runs at 16 MHz, driven by the internal oscillator. That is the maximum clock speed — no external crystal needed for full-speed operation.
