Product details

16-bit MCU for industrial and mixed-signal control

The MCU comes in a 38-pin TSSOP package with 32 I/Os. This combination makes it a fit for sensor nodes, motor control, and battery-powered instruments where low power and a wide supply range matter.

8 KB Flash and 512 B RAM — sizing the firmware

The 8 KB program memory (8K x 8 plus 256 B) is sized for moderate-complexity control loops, sensor fusion, or protocol bridging. The 512 x 8 RAM supports a few hundred bytes of stack and variable space — enough for a small RTOS or a state-machine scheduler. If your application needs over-the-air update staging or larger lookup tables, plan to compress or page-swap; the 8 KB limit is the hard ceiling.

The 105°C upper limit gives headroom above the usual 85°C industrial ceiling, useful when the PCB sits near a hot power stage or in a sealed enclosure.

TI lists the MSP430F2232TDAR as Active. The 38-pin TSSOP package is a standard footprint, and the MSP430F2xx family has broad toolchain and software support.

At the high end, it sits comfortably on a 3.3 V system rail.

Frequently asked questions

Is MSP430F2232TDAR RoHS compliant and lead-free?

The part is designated with the 'T' suffix in the order code, which typically indicates a lead-free, RoHS-compliant finish. No explicit RoHS certificate is in this record, but the standard TI lead-free plating applies to the TDA package code.

What is the closest pin-compatible alternative to MSP430F2232TDAR in this family?

Within the MSP430F2xx series, the MSP430F2232 is the base number; higher-density siblings like the MSP430F2418 (with more Flash and RAM) share the same 38-pin TSSOP footprint but differ in memory map and peripheral set. No exact pin-compatible drop-in is named in this record; verify against the TI cross-reference guide for your specific firmware size.

What is MSP430F2232TDAR's listed speed (16 MHz) on this component line?

The core runs at 16 MHz. At this speed the Flash requires zero wait states, so no performance penalty from memory access. The internal oscillator can be used as the system clock, avoiding an external crystal.
