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.","metaTitle":"MSP430G2001IPW4RQ1 16-bit MCU, 16 MHz, 512B Flash, AEC-Q100","metaDescription":"Texas Instruments MSP430G2001IPW4RQ1 16-bit MCU, 16 MHz, 512B Flash, 128B RAM, 10 I/O, -40°C to 85°C, AEC-Q100 automotive qualified.
