Product details

The part is aimed at low-power mixed-signal applications — think sensor nodes, industrial control panels, battery-powered instruments, and LIN-bus slave modules in automotive body electronics.

At 25 MHz the CPUXV2 core can service a UART interrupt, update a PID loop, and toggle a PWM output within a single 40 ns cycle. That is enough throughput for most 8- or 16-bit control tasks without needing a 32-bit part.

Memory budget: 8 KB Flash, 6 KB RAM

8 KB of Flash and 6 KB of RAM put this MCU in the compact-control tier. The Flash holds a moderate firmware image — a bootloader plus a few communication stacks and application routines. The 6 KB RAM (organized as 6K x 8) is enough for a couple of 256-byte buffers, a small state machine, and a modest call stack.

The part integrates I²C, SPI, UART/USART, LIN, and IrDA — covering the common serial buses for sensor and actuator interfacing.

Package and rework

It is at home in factory automation panels, outdoor telecom enclosures, engine-bay-adjacent modules, and HVAC controllers.

Frequently asked questions

Is MSP430F5304IRGZR obsolete or still active?

No discontinuation notice or last-time-buy has been issued.

What is the difference between MSP430F5304IRGZR and MSP430F5304IRGZT?

The two part numbers share the same silicon and package — the difference is in the reel quantity and tape-and-reel packaging suffix. The IRGZR is typically supplied in a larger reel; the IRGZT in a smaller reel. Verify the exact reel quantity with your distributor before ordering for your assembly line.

What is the closest pin-compatible alternative to MSP430F5304IRGZR?

Within the MSP430F5xx family, the MSP430F5304IRGZT is the same die and package, differing only in tape-and-reel quantity. For higher Flash/RAM, look at the MSP430F5310 or MSP430F532x variants — but verify pin compatibility against the datasheet pin maps, as peripheral sets and pinouts can differ across density options.
