Product details

What this 16-bit MCU brings to a control board

The 8-channel 10-bit ADC handles analog inputs directly, saving an external converter.

Memory and peripheral budget — fit for sensor and control loops

It is sized for a PID loop with a few hundred lines of C, a Modbus RTU slave, or a battery monitor that logs to internal Flash. The 8-channel 10-bit ADC samples at rates adequate for 50/60 Hz power-line monitoring or slow thermocouple readout — but the 10-bit resolution limits dynamic range to about 60 dB, so a precision analog front end needs an external ADC. The PWM and watchdog timer are standard for motor drive and system supervision.

Frequently asked questions

Is MSP430G2533IRHB32T end-of-life or obsolete?

No. The lifecycle status is active. It remains a current-production part suitable for new designs.

Does MSP430G2533IRHB32T have a built-in ADC?

Yes. It includes an 8-channel, 10-bit analog-to-digital converter, which can read up to eight external analog signals without an external ADC chip.

Can MSP430G2533IRHB32T replace MSP430G2553 directly?

The MSP430G2553 is a higher-density sibling with 16 KB Flash and 512 B RAM as well, but it adds a comparator and more ADC channels. Pin compatibility depends on the specific package variant — both are available in 32-VQFN, but the peripheral set differs. Check the respective datasheets for exact pin mapping and peripheral availability before substituting.
