Product details

8 MHz 16-bit core — low-power control for sensor and monitoring designs

The 8-channel 12-bit ADC (8x12b) lets it read analog inputs directly, reducing external component count. Connectivity includes SPI and UART/USART interfaces, and the peripheral set covers POR, PWM, and WDT.

8 KB Flash and 256 B RAM — sizing the firmware footprint

Program memory is 8 KB (8K x 8 plus 256 bytes for info storage). The 256-byte RAM limits runtime data buffering — expect to use Flash for constants and tables. If your application needs larger code or data space, this part is not the fit.

The part is ROHS3 compliant.

Package and supply rails — layout checklist

Housed in a 64-LQFP package (10x10 mm body) with surface-mount leads. The 48 I/O pins give good headroom for parallel buses, keypad matrices, or multiple sensor interrupts. Supply range is 1.8V to 3.6V — a single 3.0V coin cell or a 3.3V rail works without a regulator.

Frequently asked questions

Is MSP430F133IPM obsolete or discontinued?

No. The part is listed with active product status, meaning TI continues to manufacture it. There is no announced end-of-life or last-time-buy.

Is MSP430F133IPM 5V tolerant?

The evidence does not specify 5V tolerance on the I/O pins. The supply maximum is 3.6V, so driving 5V logic directly is not recommended without level translation.

What are the alternatives to MSP430F133IPM?

It is not pin-compatible and targets higher-performance automotive and industrial control applications. For a direct MSP430-family alternative, look at other MSP430x1xx devices with similar Flash and RAM sizes.
