Product details

The MSP430F5252IZQE is a 16-bit microcontroller from the MSP430F5xx series with a 25 MHz core.

The 53 general-purpose I/O lines give headroom for parallel LCD buses or a bank of discrete inputs. Brown-out detection, POR, DMA, and a PWM timer are integrated, so external supervisor ICs and PWM generators can often be removed from the BOM.

Texas Instruments has marked the MSP430F5252IZQE as Obsolete. The last-time-buy window has closed, and the part is no longer available through the factory or authorized distribution. There is no official TI successor listed in the available records; the closest pin-compatible sibling in the same family carries a different Flash/RAM configuration and should be validated for firmware fit before substituting.

Frequently asked questions

Is MSP430F5252IZQE obsolete and what is the replacement?

Yes, the MSP430F5252IZQE is obsolete per TI's product status. No official replacement part number is listed in the available records. The MSP430F5253IZQE is a pin-compatible sibling in the same family, but its Flash and RAM sizes differ — firmware and memory-map validation are required before substituting.

Does MSP430F5252IZQE support I2C and SPI simultaneously?

The connectivity listing includes both I²C and SPI interfaces. Whether they can operate simultaneously depends on the specific peripheral mapping and pin multiplexing — consult the MSP430F5xx family datasheet for the exact shared-resource constraints.

What is MSP430F5252IZQE's listed speed?

The core processor runs at 25 MHz, which is typical for the MSP430F5xx series and sufficient for most sensor-fusion and control-loop tasks at this power envelope.

Is MSP430F5252IZQE compatible with MSP430F5253IZQE?

The MSP430F5253IZQE is a pin-compatible sibling in the same BGA package and family. The key difference is program memory size — the 5253 carries a different Flash/RAM configuration. Board-level swap is possible, but firmware must be re-verified for memory-map and peripheral differences.
