Product details

16 MHz, 2 KB Flash, 256 B RAM — what fits in that envelope

The MSP430G2232IRSA16R: The 10 I/O pins and integrated 8-channel 10-bit ADC mean it can handle several analog inputs without external muxing. Connectivity runs through I²C, SPI, and the USI module, which covers most low-speed sensor and actuator buses.

16-QFN with exposed pad — layout notes

Package is a 16-QFN (4x4 mm) with exposed pad.

The MSP430G2xx family has broad second-source compatibility within the series — pin-compatible across density options — but no official cross-reference alternate is recorded for this exact order code.

Frequently asked questions

Where can I buy MSP430G2232IRSA16R available via RFQ confirmation?

Submit a request for quote and we will confirm current availability and pricing at quote time — no stock count or lead-time number is published here because the channel picture changes daily.

What is the difference between MSP430G2232IRSA16R and MSP430G2232IRSA16T?

Both share the same die, Flash, RAM, and package. The difference is the reel quantity and tape width — the 'R' suffix typically indicates a larger reel (e.g., 2500 units) versus the 'T' suffix for smaller reels (e.g., 250 units). For a production BOM, the 'R' variant is the standard volume option; the 'T' suits prototyping or low-volume builds. Electrical and timing specs are identical.

Does MSP430G2232IRSA16R have an equivalent or replacement part?

Within the MSP430G2xx family, pin-compatible density options exist — for example, the MSP430G2452 offers more Flash and RAM if the firmware grows. For a direct drop-in, the MSP430G2232IRSA16T is the same die with a different reel quantity.
