Product details

It carries 8 KB of Flash program memory (8K x 8 plus 256 B) and 512 x 8 bytes of RAM — enough for moderate embedded control firmware, sensor fusion, or communication protocol handling.

Peripheral set and I/O — sizing the BOM fit

The 12-channel 10-bit ADC (A/D 12x10b) covers analog inputs like thermistors, potentiometers, or current-sense resistors.

Package and footprint — 38-TSSOP layout notes

Housed in a 38-TSSOP (0.240", 6.10 mm width) surface-mount package, the MSP430F2232IDA fits on space-constrained two-layer boards. The 38-pin TSSOP body is 9.7 mm long with a 0.65 mm pitch — standard for automated assembly. No exposed thermal pad, so heat dissipation is through the leads; keep the ambient below 85°C for the full speed range.

Frequently asked questions

What is the difference between MSP430F2232IDA and MSP430F2232IRHB?

The two devices share the same core, memory, and peripheral set. The key difference is the package: MSP430F2232IDA comes in a 38-TSSOP, while MSP430F2232IRHB uses a 40-VQFN. The QFN variant offers a smaller footprint and better thermal performance but requires a different PCB layout.

What is the closest pin-compatible alternative to MSP430F2232IDA in the MSP430F2xx family?

Within the same 38-TSSOP footprint, the MSP430F2232IDA is pin-compatible with other MSP430F2xx devices in the 38-pin TSSOP package, such as the MSP430F2132IDA (lower Flash) or MSP430F2418IDA (higher Flash and RAM). Verify the specific memory and peripheral differences against your firmware requirements.

What is the MSP430F2232IDA's listed speed?

The MSP430F2232IDA is rated for a 16 MHz CPU clock speed. This is the maximum core frequency supported by the MSP430 CPU16 processor in this device.
