Product details

What this MSP430G2433IN20 brings to a low-power control design

The through-hole 20-pin DIP (0.300" width) is breadboard-friendly and easy to hand-solder, making this a common choice for prototyping, low-volume production, and field-repair replacements where a surface-mount part would be harder to service.

Memory and peripheral fit for sensor and control loops

With 8 KB Flash and 512 bytes of RAM, the MSP430G2433IN20 is sized for small code footprints — think a few hundred lines of C for a temperature/humidity sensor with I²C output, or a PWM fan controller with LINbus reporting. The 8-channel 10-bit ADC covers analog inputs like thermistors or potentiometers without an external converter. The brown-out detect and watchdog timer (listed peripherals) add reset reliability for unattended equipment.

Frequently asked questions

What is the closest pin-compatible alternative to MSP430G2433IN20 in the MSP430G2xx family?

Within the same 20-pin DIP footprint, the MSP430G2453IN20 is a direct pin-compatible sibling. The G2453 doubles the Flash to 8 KB (same as the G2433) but adds a larger RAM option — check the specific memory map if you need more RAM than 512 bytes. Both share the same peripheral set and supply range.

Is MSP430G2433IN20 RoHS compliant?

Yes, TI lists this part as ROHS3 Compliant.
